Abstract

Multiflowering (MF) is a condition in which a plant bears more than two flowers per peduncle (FPP) on a single flowering node. In legumes, MF is reported in peas, chickpeas, and lentils and is reportedly governed by one to two recessive gene(s) or polygenes (Fn, Fna, Hr, Dne, Lf, Sn, nep–1, nep–2, sfl, and cym). MF is a relatively stable trait, although influenced by G × E interaction, particularly by temperature (11°C–20°C). Among the various genes regulating MF, the sfl gene results in the formation of two FPP in chickpea and was fine-mapped at 5.1 cM on LG6. The fine mapping and functional characterization of all the known MF genes will help in the manipulation of the number of FPPs and also the total number of flowers per plant through MAS (marker-assisted selection) or genome editing. This review investigates the roles, pathways, and genomic locations of all the MF genes in various legumes and the possibility of realizing better yield.

解开豌豆、扁豆和鹰嘴豆的多花性状：遗传见解和育种进展

多花（MF）是一种植物在一个花节上每花梗（FPP）有两朵以上花的情况。在豆类中，据报道，MF存在于豌豆、鹰嘴豆和小扁豆中，并由一到两个隐性基因或多基因（Fn、Fna、Hr、Dne、Lf、Sn、nep-1、nep-2、sfl和cym）控制。虽然受到G × E相互作用的影响，特别是温度（11°C - 20°C）的影响，但MF是一个相对稳定的性状。在调控MF的多个基因中，sfl基因导致鹰嘴豆形成两个FPP，并在LG6上的5.1 cM处被精细定位。所有已知MF基因的精细定位和功能表征将有助于通过MAS（标记辅助选择）或基因组编辑来操纵FPPs的数量和每株花的总数。本文综述了MF基因在各种豆科植物中的作用、途径、基因组定位以及实现更高产量的可能性。
