小麦（Triticum aestivum L.）是世界上最重要的粮食作物之一。体细胞胚胎发生是由生长素激素的存在引发的事件，用于诱导体细胞转化为胚胎细胞。体细胞胚胎发生是植物全能性的重要过程。生长素的作用在胚胎发生的各个阶段，包括极性建立、去分化、再分化和形态发生中被广泛理解。许多Aux/IAAs和ARF是生长素信号转导的一部分，它们在胚胎发育过程中发挥着不同的作用。在此分析中，Aux/IAA和ARF的T.已经在基因组水平上分析了普通小麦;它们的结构、功能和进化相关性被确定。T.通过差异表达研究发现，普通小麦专门调节轴形成、分生组织定型和其它再分化过程。
Wheat (Triticum aestivum L.) is one of the most important food crops in the world. Somatic embryogenesis is an event that is triggered by the presence of auxin hormone for the induction of somatic cells to get converted to embryonic cells. Somatic embryogenesis represents the most important process of totipotency of plants. The role of auxins is widely understood during various stages of embryogenesis including polarity establishment, de-differentiation, re-differentiations, and morphogenesis. Many of the Aux/IAAs and ARFs which are part of auxin signaling components have been identified to play various roles during embryogenesis. In this analysis, the Aux/IAAs and ARFs of T. aestivum have been analyzed at the genome-scale; their structure, function, and evolutionary relatedness were determined. Several Aux/IAAs and ARFs components of T. aestivum have been found to exclusively regulate axis formation, meristem commitment, and other re-differentiation processes by differential expression studies.
