Abstract:Under exposure of wheat plants to high temperatures (33, 37, and 43°C), the level of transcripts of the genes encoding proapoptotic proteins-TaMCAII (encodes type II metacaspase) and TaBAX (functional homologue of the CDF1 gene of Arabidopsis thaliana)-in leaf cells increased. This process at temperatures of 37 and 43°C passed ahead of (in the case of TaBAX mRNA) or was accompanied by (in the case of TaMCAII mRNA) the emergence of signs of nucleosomal DNA degradation in leaves. The accumulation of malondialdeh… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
