Overexpression of Arabidopsis in Hexaploid Wheat ( L.) Alters Plant Development and Freezing Tolerance.

Jasmonates are plant hormones that are involved in the regulation of different aspects of plant life, wherein their functions and molecular mechanisms of action in wheat are still poorly studied. With the aim of gaining more insights into the role of jasmonic acid (JA) in wheat growth, development, and responses to environmental stresses, we have generated transgenic bread wheat plants overexpressing (), one of the key genes of the JA biosynthesis pathway. Analysis of transgenic plants showed that overexpression affects wheat development, including germination, growth, flowering time, senescence, and alters tolerance to environmental stresses.
