The isochorismate pathway is negatively regulated by salicylic acid signaling in O3-exposed Arabidopsis.

abstract：MAIN CONCLUSIONS:Compared to Artemisia ordosiea Kraschen, a higher content of α-tocopherol in Artemisia sphaerocephala Kraschen under salt stress inhibits the conversion of linoleic acid (C18:2) into linolenic acid (C18:3), maintains cell membrane stability and contributes to higher salt resistance. Artemisia sphaeroce...

The enzyme has requirements for Mg(2+) and ATP in the biosynthetic reaction and in addition will catalyse a γ-glutamyl transferase reaction in the presence of Mn(2+) and arsenate. The enzyme is inhibited by AMP, CTP, glycine and alanine. Thes...

abstract：:Plant defence strategies usually involve the action of several gene products. Transgenic resistance strategies are likely to have enhanced efficacy when they involve more than one transgene. Here we explore possible mechanisms for the co-delivery of multiple effectors via a single transgene. As an example we report th...
