1. {"_":"The Cinderella tree, - A soap story.","i":["Quillaja saponaria"]}
PMID:日期:2025-11-25The Chilean soapbark tree, Molina, grows in the central part of Chile. As its name suggests, the tree is a natural source of soap. Indeed, the name is derived from the indigenous Chilean word 'küllay', which means 'soap'. Soapbark is not the only plant to produce natural soaps. Other examples include the perennial soapwort (), which grows in Europe and has historically been used as a source of gentle soap for washing delicate fabrics, including allegedly the Turin shroud; and (soapberry or soapnut), which grows in temperate and tropical regions of the world. The soapy properties of these plants are due to their production of glycosylated compounds known as saponins. In fact, saponins are found across the Plant Kingdom, not just in species with 'soap' in their names, and are one of the largest groups of plant natural products. The major saponin produced by , which is known as QS-21, is a potent immunostimulant and has been approved for use in human vaccines. QS-21, which is the first naturally occurring plant glycoside to be used as an adjuvant, is a highly complex molecule that is produced only by . This review covers the history of the soapbark tree, the discovery of QS-21 and the potential for making the next generation of saponin vaccine adjuvants using engineering biology approaches.

2. From Mysore to Cambridge and back: The education of a groundnut breeder.
PMID:日期:2023-12-07Studies that show how empire influenced the development of plant genetics add to the established history of genetics and 20th-century agricultural science. One approach to broadening this history is to consider the contributions of students studying abroad and their greater careers back home. Research agendas differed between and within institutions, much as they do today. This article explores the postgraduate education of an Indian groundnut breeder. It highlights the structural challenges faced by researchers at agricultural departments who sought promotion through education and examines the consequences for plant breeding and for farmers. Through the biography of V.K. Badami, this article contributes to debates about genetics and plant breeding in the history of science. Badami, an accomplished breeder in the Mysore Department of Agriculture, took a leave to study genetics at the University of Cambridge. His professors nearly failed him, yet Badami's groundnut breeding experiments proved influential for Indian farmers as well as advances in crop science. This history adds to the thesis that academic genetics varied in support of professional plant breeding by comparing institutional expections between Mysore and Cambridge.The argument is developed by reading Badami's student records along with his groundnut breeding experiments in South India.The study connects the disciplinary history of genetics to plant breeding for the British empire.Badami's experience at Cambridge is indicative of the power relationship between academic genetics and imperial plant breeding in the early 20th century. In this case, his commitments as an Indian agricultural officer conflicted with the discipline's devotion to quantitative analysis.

3. {"_":": Agricultural extension and the origins of the hybrid corn seed industry.","i":["The Cornbelt's Last Open Pollinated Corn"]}
PMID:日期:2023-08-14Agricultural extension is recognized as an important pathway for generating changes in individual farmers' practices and therefore broader patterns of production. In the United States, historical research has implicated extension work in transformations that privileged White farmers and wealthier operations over other producers and that fostered the industrialization and consolidation of farms. This article examines the work of one early 20th-century extension agent and the demonstrations he used to teach farmers how to choose and keep corn seeds and to identify the best performing corn varieties for a particular location. This history can inform contemporary efforts to develop more socially and ecologically aware approaches to agricultural research, extension, and production by emphasizing the need for measures of success that align with community-level objectives and for larger institutional structures that support and sustain such goals. The article examines the histories of agricultural extension and crop development in the early 20th-century United States. It discusses the role of farm demonstrations, including the participation of farmer-breeders, in the development of spread of higher yielding corn varieties in the Midwestern states in the 1910s and 1920s. It highlights the emphasis placed on finding locally or regionally appropriate varieties in some early corn extension activities and dwells on the irony that these locally specific endeavors played a role in the development of universalized solutions.The article examines and contextualizes an unusual archival document as an entry point into these histories: , a two-volume work prepared by Martin Luther Mosher (1882-1982). Mosher was the first county agricultural extension agent in the state of Iowa and worked in extension until his retirement in 1950.The article makes three main observations: (1) is best read as an agricultural demonstration; (2) is Mosher's attempt to grapple with the material legacies of his extension work in relation to the different agricultural life he idealized; and (3) Mosher's work exemplifies the complex relationships and expectations seen among breeders, seed companies, extension agents, and farmers in the early 20th-century United States.The article concludes that Mosher's work with open-pollinated corn varieties offers insight into the importance of agricultural extension as a means of crop development and highlights the contingent nature of agricultural industrialization.

4. Visualising an invisible symbiosis.
PMID:日期:2021-02-11Despite the vast abundance and global importance of plant and microbial species, the large majority go unnoticed and unappreciated by humans, contributing to pressing issues including the neglect of study and research of these organisms, the lack of interest and support for their protection and conservation, low microbial and botanical literacy in society, and a growing disconnect between people and nature. The invisibility of many of these organisms is a key factor in their oversight by society, but also points to a solution: sharing the wealth of visual data produced during scientific research with a broader audience. Here, we discuss how the invisible can be visualised for a public audience, and the benefits it can bring. Whether too small, slow or concealed, the majority of species on Earth go unseen by humans. One such rather unobservable group of organisms are the arbuscular mycorrhizal (AM) fungi, who form beneficial symbioses with plants. AM symbiosis is ubiquitous and vitally important globally in ecosystem functioning, but partly as a consequence of its invisibility, it receives disproportionally little attention and appreciation. Yet AM fungi, and other unseen organisms, need not remain overlooked: from decades of scientific research there exists a goldmine of visual data, which if shared effectively we believe can alleviate the issues of low awareness. Here, we use examples from our experience of public engagement with AM symbiosis as well as evidence from the literature to outline the diverse ways in which invisible organisms can be visualised for a broad audience. We highlight outcomes and knock-on consequences of this visualisation, ranging from improved human mental health to environmental protection, making the case for researchers to share their images more widely for the benefit of plants (and fungi and other overlooked organisms), people and planet.

5. {"_":"Postharvest seed coat darkening in pinto bean () is regulated by , an allele of the basic helix-loop-helix transcription factor .","i":["Phaseolus vulgaris",{"_":"P","sup":["sd"]},"P"]}
PMID:日期:2020-08-19Pinto bean () is one of the leading market classes of dry beans that is most affected by postharvest seed coat darkening. The process of seed darkening poses a challenge for bean producers and vendors as they encounter significant losses in crop value due to decreased consumer preference for darker beans. Here, we identified a novel allele of the gene, , responsible for the slow darkening seed coat in pintos, and identified trait-specific sequence polymorphisms which are utilized for the development of new gene-specific molecular markers for breeding. These tools can be deployed to help tackle this economically important issue for bean producers. Postharvest seed coat darkening in pinto bean is an undesirable trait that reduces the market value of the stored crop. Regular darkening (RD) pintos darken faster after harvest and accumulate higher level of proanthocyanidins (PAs) compared to slow darkening (SD) cultivars. Although the markers cosegregating with the SD trait have been known for some time, the () gene identity had not been proven.Here, we identified as a candidate for controlling the trait. Genetic complementation, transcript abundance, metabolite analysis, and inheritance study confirmed that is the gene. is another allele of the () gene, whose loss-of-function alleles result in a white seed coat. encodes a bHLH transcription factor with two transcript variants but only one is involved in PA biosynthesis. An additional glutamate residue in the activation domain, and/or an arginine to histidine substitution in the bHLH domain of the transcript in the SD cultivar is likely responsible for the reduced activity of this allele compared to the allele in a RD cultivar, leading to reduced PA accumulation.Overall, we demonstrate that a novel allele of , , is responsible for the SD phenotype, and describe the development of new, gene-specific, markers that could be utilized in breeding to resolve an economically important issue for bean producers.

6. A commercial arbuscular mycorrhizal inoculum increases root colonization across wheat cultivars but does not increase assimilation of mycorrhiza-acquired nutrients.
PMID:日期:2020-01-03Production and heavy application of chemical-based fertilizers to maintain crop yields is unsustainable due to pollution from run-off, high CO emissions, and diminishing yield returns. Access to fertilizers will be limited in the future due to rising energy costs and dwindling rock phosphate resources. A growing number of companies produce and sell arbuscular mycorrhizal fungal (AMF) inoculants, intended to help reduce fertilizer usage by facilitating crop nutrient uptake through arbuscular mycorrhizas. However, their success has been variable. Here, we present information about the efficacy of a commercially available AMF inoculant in increasing AMF root colonization and fungal contribution to plant nutrient uptake, which are critical considerations within the growing AMF inoculant industry. Arable agriculture needs sustainable solutions to reduce reliance on large inputs of nutrient fertilizers while continuing to improve crop yields. By harnessing arbuscular mycorrhizal symbiosis, there is potential to improve crop nutrient assimilation and growth without additional inputs, although the efficacy of commercially available mycorrhizal inocula in agricultural systems remains controversial.Using stable and radioisotope tracing, carbon-for-nutrient exchange between arbuscular mycorrhizal fungi and three modern cultivars of wheat was quantified in a non-sterile, agricultural soil, with or without the addition of a commercial mycorrhizal inoculant.While there was no effect of inoculum addition on above-ground plant biomass, there was increased root colonization by arbuscular mycorrhizal fungi and changes in community structure. Inoculation increased phosphorus uptake across all wheat cultivars by up to 30%, although this increase was not directly attributable to mycorrhizal fungi. Carbon-for-nutrient exchange between symbionts varied substantially between the wheat cultivars.Plant tissue phosphorus increased in inoculated plants potentially because of changes induced by inoculation in microbial community composition and/or nutrient cycling within the rhizosphere. Our data contribute to the growing consensus that mycorrhizal inoculants could play a role in sustainable food production systems of the future.

7. Overcoming plant blindness in science, education, and society.
PMID:DOI:日期:2019-07-01Plants are amazing organisms. They make up around 80% of all biomass on Earth, play important roles in almost all ecosystems, and support humans and other animals by providing shelter, oxygen, and food. Despite this, many people have a tendency to overlook plants, a phenomenon known as "plant blindness." Here, we explore the reasons behind plant blindness, discuss why some people are relatively unaffected by it, and promote education around plant science to overcome this phenomenon and raise awareness of the importance of plants in the wider community. Summary Many people tend to overlook the importance of plants in the biosphere. This phenomenon is described as "plant blindness," a term proposed 20 years ago to denote the inability of a person to notice plants and/or appreciate their significance. To explore why some people seem immune to plant blindness, we asked plant scientists on Twitter why they became interested in plants. Many replied that their interest developed from early experiences in life or inspiring teachers at school. Others were attracted to the scientific disciplines related to plant science or valued the contribution of plants to global ecosystems and human civilization. Based on these anecdotes and the empirical findings of other researchers, we argue that plants should play a more central role in biological education, from the early years to university and beyond. Furthermore, as plant scientists, we should do our best to raise awareness about the fascinating aspects of plants and their importance in human affairs within the wider community.

8. Opening the dialogue: Research networks between high- and low-income countries further understanding of global agro-climatic challenges.
PMID:DOI:日期:2019-02-02Societal Impact Statement In the modern world it has become increasingly urgent to balance human food security needs with environmental needs. These needs are not necessarily mutually exclusive, and can be synergistic. The Cambridge-India Network for Translational Research in Nitrogen (CINTRIN) seeks to reduce nitrogen fertilizer overapplication (and the resulting environmental pollution) in Indian agriculture: a situation with various scientific and sociopolitical drivers, which equally have various sociopolitical and scientific solutions. By listening to the needs of local farmers and applying the knowledge and resources of global plant science research, achieving higher crop yields with less nitrogen is an achievable prospect for India.
