Effect of volatile methyl jasmonate on the oxylipin pathway in tobacco, cucumber, and arabidopsis.

abstract：:The metabolism of soluble nucleotides was investigated in wheat (Triticum aestivum var. Olympic) aleurone layers treated with gibberellic acid. Whereas nucleotide levels were relatively unaffected by the treatment, a transient increase was observed in the incorporation of (32)P. The effect was maximal 30 to 60 minutes...
