Unlabelled: Studies 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.
Summary: 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.

Herbivore insects deploy salivary effectors to manipulate the defense of their host plants. However, it remains unclear whether small RNAs from insects function as effectors in regulating plant-insect interactions. Here, we report that a microRNA (miR29-b) found in the saliva of phloem-feeding whitefly (Bemisa tabaci) can transfer into the host plant phloem during feeding and fine-tune the defense response of tobacco (Nicotiana tabacum).

Heat stress poses a significant challenge for maize production, especially during the spring when high temperatures disrupt cellular processes, impeding plant growth and development. The B-cell lymphoma-2 (Bcl-2) associated athanogene (BAG) gene family is known to be relatively conserved across various species. It plays a crucial role as molecular chaperone cofactors that are responsible for programmed cell death and tumorigenesis.

Objectives: Toona sinensis, commonly known as Chinese toon, is a perennial woody plant with significant economic and ecological importance. This study employed whole-genome resequencing of 180 T. sinensis samples collected from Shandong to analyze genetic variation and diversity, ultimately identifying 18,231 high-quality SNPs after rigorous quality control and linkage disequilibrium pruning.

Background: Drought stress is a major environmental constraint affecting crop yields. Plants in agricultural and natural environments have developed various mechanisms to cope with drought stress. Identifying genes associated with drought stress tolerance in potato and elucidating their regulatory mechanisms is crucial for the breeding of new potato germplasms.
