- Аннотация: Analysis of interactions between mutations abruptus and leafy and previous data on interaction of abruptus with homeotic mutations apetala1, apetala2, and apetala3 showed that the functions of the ABRUPTUS/PINOID (ABR/PID) gene are as follows: (1) it directs pattern formation in inflorescence axis specifying the development either of floral meristem (FM) or of cauline leaves; (2) in concert with the leafy gene, it participates in the formation of FM; (3) it is involved in the determination and the formation of floral organ primordia in the first, second, and third whorls. Auxin accumulation in the abr mutant cells in callus culture was shown indicating the involvement of the ABR/PID gene in regulation of auxin efflux from cells. It is suggested that the ABR/PID expression in the sites of formation of FM and floral organs leads to local reduction in auxin level, which in turn, enhances expression of the LFY and homeotic genes responsible for FM formation and differentiation.
