Abstract

Pulses are important crops for global food security and are highly adaptable to diverse environmental conditions. Despite these merits, pulses often face neglect and undervaluation in production. Conventional breeding has been successful for centuries in improving various traits, based on their superior agronomic performance. However, this is a phenotype-based selection that is laborious, expensive, inefficient, error-prone, and often poorly adaptive. To address these challenges, molecular breeding has emerged as a valuable approach, bridging the gap between phenotype and genotype.

Consequently, we aimed to review recent advances in molecular breeding for major pulse crops, and the introgression of novel genes providing a comprehensive overview of breeding strategies for sustainable food security, particularly in developing countries. Genetic improvement through molecular breeding tools has been used to reliably improve pulse nutritional quality traits (such as taste, aroma, protein digestibility, essential amino acid profile, and the absence of anti-nutritional factors) and resistance to environmental stresses. Accordingly, the integration of next-generation genome sequencing, genome-wide association studies, high-throughput phenotyping, and omics research approaches are accelerating the discovery of the genetic loci underlying these traits and improving pulse research, mainly for key pulses like soybean, chickpea, broad bean, common bean, field pea, grass pea, cowpea, mung bean, and lentil. In general, molecular interventions in pulse breeding hold great promise for improving food and nutrition security, particularly in developing countries.

分子育种的最新进展以及对主要脉动改良工作的重要见解,以促进可持续粮食安全
豆类是全球粮食安全的重要作物,对各种环境条件的适应性很强。尽管豆类具有这些优点,但在生产中却常常受到忽视,价值被低估。数百年来,传统育种方法成功地改良了豆类的各种性状,这些性状都是基于其优异的农艺表现。然而,这是一种基于表型的选择,费力、昂贵、低效、易出错,而且往往适应性差。为应对这些挑战,分子育种已成为弥合表型与基因型之间差距的一种重要方法。因此,我们旨在回顾主要豆类作物分子育种的最新进展,以及新基因的导入情况,为可持续粮食安全的育种战略提供一个全面的概览,尤其是在发展中国家。通过分子育种工具进行的遗传改良已被用于可靠地改善豆类的营养品质性状(如口感、香气、蛋白质消化率、必需氨基酸谱和无抗营养因子)和抗环境胁迫性。因此,下一代基因组测序、全基因组关联研究、高通量表型分析和 omics 研究方法的整合正在加速发现这些性状的遗传位点,并改进主要针对大豆、鹰嘴豆、蚕豆、庶豆、大田豌豆、禾本科豌豆、豇豆、绿豆和小扁豆等关键豆类的豆类研究。总体而言,对豆类育种的分子干预在改善粮食和营养安全方面大有可为,尤其是在发展中国家。

期刊介绍: Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
