D53 represses rice blast resistance by directly targeting phenylalanine ammonia lyases

J Integr Plant Biol. 2024 Sep;66(9):1827-1830. doi: 10.1111/jipb.13734. Epub 2024 Jun 28.

Abstract

In rice, DWARF 53 directly binds to the promoters of seven phenylalanine ammonia lyase genes, OsPAL1˜OsPAL7, and represses their expression, leading to decreased lignin accumulation and compromised resistance against Magnaporthe oryzae.
