Abstract

As an important legume, common bean (Phaseolus vulgaris L.) is widely utilized as a staple crop and as a source of protein, minerals and vitamins for resource-poor populations in the tropics and in subtropical regions. However, substantial amounts of common beans may be lost due to infestations by bruchids and nematodes, among other pests. With the discovery of arcelins, a class of seed proteins, a biotechnological approach to addressing attacks by bruchids may be developed. Arcelins are components of a multigene family encoded by the APA locus [arcelin (Arc)/Phytohemagglutinin (PHA)/α-Amylase Inhibitor (αAI)] and have been shown to confer resistance to bruchids. Here we present an overview of the APA locus and briefly discuss the function of the components that make up this gene family, while linking this to the biocidal effects of the arcelin proteins and their biotechnological potential in the control of bruchids in common bean and other leguminous crops.

综述了APA基因座和arcelin蛋白及其在野鼠病控制中的生物技术潜力

普通豆(Phaseolus vulgaris L.)是一种重要的豆科植物，在热带和亚热带地区资源贫乏的人群中被广泛用作主要作物和蛋白质、矿物质和维生素的来源。然而，大量的普通豆可能会因糙毛虫和线虫等害虫的侵扰而损失。随着arcelins(一类种子蛋白)的发现，一种解决野鼠攻击的生物技术方法可能会发展起来。Arcelins是由APA位点[arcelin (Arc)/植物血凝素(PHA)/α-淀粉酶抑制剂(αAI)]编码的多基因家族的组成部分，并已被证明具有对野蓟的抗性。本文介绍了APA基因座的概况，并简要讨论了组成该基因家族的组分的功能，同时将其与arcelin蛋白的生物杀灭作用及其在控制普通豆和其他豆科作物糙腿病中的生物技术潜力联系起来。

期刊介绍： Agri Gene publishes papers that focus on the regulation, expression, function and evolution of genes in crop plants, farm animals, and agriculturally important insects and microorganisms. Agri Gene strives to be a diverse journal and topics in multiple fields will be considered for publication so long as their main focus is on agriculturally important organisms (plants, animals, insects, or microorganisms). Although not limited to the following, some examples of potential topics include: Gene discovery and characterization. Genetic markers to guide traditional breeding. Genetic effects of transposable elements. Evolutionary genetics, molecular evolution, population genetics, and phylogenetics. Profiling of gene expression and genetic variation. Biotechnology and crop or livestock improvement. Genetic improvement of biological control microorganisms. Genetic control of secondary metabolic pathways and metabolic enzymes of crop pathogens. Transcription analysis of beneficial or pest insect developmental stages Agri Gene encourages submission of novel manuscripts that present a reasonable level of analysis, functional relevance and/or mechanistic insight. Agri Gene also welcomes papers that have predominantly a descriptive component but improve the essential basis of knowledge for subsequent functional studies, or which provide important confirmation of recently published discoveries provided that the information is new.
