Ethylene Contributes to maize insect resistance1-Mediated Maize Defense against the Phloem Sap-Sucking Corn Leaf Aphid.
Signaling networks among multiple phytohormones fine-tune plant defense responses to insect herbivore attack. Previously, it was reported that the synergistic combination of ethylene (ET) and jasmonic acid (JA) was required for accumulation of the maize insect resistance1 (mir1) gene product, a cysteine (Cys) proteinase that is a key defensive protein against chewing insect pests in maize (Zea ...
متن کاملThe Recently Identified Isoleucine Conjugate of cis-12-Oxo-Phytodienoic Acid Is Partially Active in cis-12-Oxo-Phytodienoic Acid-Specific Gene Expression of Arabidopsis thaliana
Oxylipins of the jasmonate family are active as signals in plant responses to biotic and abiotic stresses as well as in development. Jasmonic acid (JA), its precursor cis-12-oxo-phytodienoic acid (OPDA) and the isoleucine conjugate of JA (JA-Ile) are the most prominent members. OPDA and JA-Ile have individual signalling properties in several processes and differ in their pattern of gene express...
متن کاملCyclophilin 20–3 is positioned as a regulatory hub between light-dependent redox and 12-oxo-phytodienoic acid signaling
The jasmonate family of phytohormones plays central roles in plant development and stress acclimation. However, the regulatory modes of their signaling circuitry remain largely unknown. Here we describe that cyclophilin 20-3 (CYP20-3), a binding protein of (+)-12-oxo-phytodienoic acid (OPDA), crisscrosses stress responses with light-dependent redox reactions, which fine-tunes the activity of ke...
متن کاملCell wall composition as a maize defense mechanism against corn borers.
European and Mediterranean corn borers are two of the most economically important insect pests of maize (Zea mays L.) in North America and southern Europe, respectively. Cell wall structure and composition were evaluated in pith and rind tissues of resistant and susceptible inbred lines as possible corn borer resistance traits. Composition of cell wall polysaccharides, lignin concentration and ...
متن کاملEfficient synthesis of (+)-cis-12-oxo-phytodienoic acid by an in vitro enzymatic reaction.
12-Oxo-phytodienoic acid (OPDA) is an important metabolite on the octadecanoid pathway of plants. This study shows an efficient in vitro synthesis of (+)-cis-OPDA by using a flaxseed extract and an allene oxide cyclase. The OPDA yield of the reaction in this study was almost 7-fold higher than that in the conventional reaction with the flaxseed extract.
