Sterols, which are isoprenoid derivatives, are structural components of biological membranes. Special attention is now being given not only to their structure and function, but also to their regulatory roles in plants. Plant sterols have diverse composition; they exist as free sterols, sterol esters with higher fatty acids, sterol glycosides, and acylsterol(More)
Recently, the role of salicylic acid in plant cell responses to various effects has been intensely studied by many researchers. It was shown that pathogens induce production of large amounts of salicylic acid in plant cells (its concentration may increase by one or two orders of magnitude) [1, 2]. Note that salicylic acid may be released into the apoplast(More)
53 Sterols are an important structural element of bio logical membranes. Unlike animals, higher plants have a complex sterol composition [1], the main com ponents of which are β sitosterol, stigmasterol, and campesterol. We have previously shown the presence of the main types of phytosterols in wheat roots [2]. Today, the research of the functions of(More)
Three homeologous copies of the TaSMT1 gene for C24-sterol methyltransferase, which are located on chromosomes A, B, and D of Triticum aestivum hexaploid genome, were discovered. The bioinformatic analysis of the structure of these genes and sequencing de novo promoter sequences revealed differential expression of homeologous TaSMT1 genes in leaves and(More)
