Abstract

One of the most important traits in plant domestication and breeding is the stem growth habit, which can be determinate (terminated) or indeterminate (not terminated). Some taxa have a semideterminate stem growth habit. In different crops preference can be given to cultivars with different stem growth habits. Because of this, among angiosperms for this trait, pronounced homologous series in hereditary variability are observed. The review considers molecular genetic mechanisms controlling the stem growth habit in dicotyledonous and monocotyledonous plants, which underlie phenotypic variation. Data on the known homologs of the Arabidopsis TFL1 gene are presented. Comparison of modern data on the genetic control of stem growth habit in the representatives of different taxa of angiosperms points to the evolutionary conservation of molecular genetic mechanisms controlling the initiation of flowering, as well as to the conserved functionality of the genes involved in this process.

TFL1直系同源物在确定植物建筑学中的作用

摘要

植物驯化和育种中最重要的特征之一是茎的生长习性，其可以确定（终止）或不确定（不终止）。一些分类群具有半确定的茎生长习性。在不同的作物中，可以优先选择具有不同茎生长习性的品种。因此，在该特性的被子植物中，观察到明显的遗传序列同源序列。审查认为控制双子叶植物和单子叶植物的茎生长习性的分子遗传机制，这是表型变异的基础。关于拟南芥 TFL1已知同源物的数据基因被提出。关于被子植物不同分类群中茎生长习性的遗传控制的现代数据的比较表明，控制开花的分子遗传机制的进化保守性以及该过程中所涉及基因的保守功能。
