Gene is Associated With Sex Determination in .

In the past decade, progress has been made in sex determination mechanism in . However, genes responsible for sexual differentiation and its mechanism in remain unknown. Here, we identify a sex determination candidate gene coding adenine phosphoribosyl transferase 3 () in .

[Allelopathy of grape root aqueous extracts].

Taking the tissue-cultured seedlings of grape cultivar Red Globe as test objects, this paper examined the effects of their root aqueous extracts on seedling's growth, with the allelochemicals identified by LC-MS. The results showed that 0.02 g x ml(-1) (air-dried root mass in aqueous extracts volume; the same below), 0.
