The 2'-O-methyladenosine nucleoside modification gene OsTRM13 positively regulates salt stress tolerance in rice.

abstract：:Sexual reproduction in higher plants uses pollination, involving interactions between pollen and pistil. Self-incompatibility (SI) prevents self-fertilization, providing an important mechanism to promote outbreeding. SI is controlled by the S-locus; discrimination occurs between incompatible pollen, which is rejected,...
