The population of P. capsici on pepper in Yunnan was diverse and it suggested that A1A2 mating type might play an important role on sexual reproduction of P. capsici.
云南辣椒疫霉群体组成较为复杂,A1A2交配型可能在云南辣椒疫霉的有性生殖中起到了重要的作用,成为影响群体结构的一个重要途径。
It was found first in yeast cell, and participated in mating type gene silencing, telomere gene silencing, and rDNA recombination, to maintain genic stability. It had important relationship with substance metabolism and longevity and was deacetylase depending on NAD+.
沉默信息调节因子SIR2(Silent information regulator 2)是调节生物体衰老进程的一个重要基因,首先在酵母细胞中发现,参与了酵母菌交配型基因沉默、端粒区基因沉默和rDNA重组,维持了基因的稳定性,并与物质代谢和长寿有着很大的关系,是依赖NAD+的去乙酰化酶,能够去乙酰化多种底物,从而介导不同生物效应。
