Abstract

The theoretical substantiation and new scientific decision of ability to genetic construction of agriculturally valuable inflorescence structure in oil crops of Brassicaceae family are proposed on the examples of A. thaliana genes AP1, BP1 and TFL1. New types of plants are more suitable to machine seed harvesting as a result of decreasing non-simultaneous ripeness of seeds within inflorescences. It has been determined that A. thaliana forms inflorescences with new combinations of untypical for family Brassicaceae features by the effects of recessive alleles ap1-1, bp-1 and tfl1-2 expression.

摘要

以拟南芥基因AP1、BP1和TFL1为例,提出了十字花科油料作物具有农业价值的花序结构遗传构建能力的理论依据和新的科学决策。由于花序内种子成熟不同步性降低,新型植物更适合机械采收种子。已经确定,拟南芥通过隐性等位基因ap1-1、bp-1和tfl1-2的表达效应,形成了具有十字花科非典型特征新组合的花序。
