AtMYB44 Positively Regulates the Enhanced Elongation of Primary Roots Induced by N-3-Oxo-Hexanoyl-Homoserine Lactone in Arabidopsis thaliana
N-acyl-homoserine lactones (AHL) are the quorum-sensing (QS) signal molecules used by many gram-negative bacteria to coordinate their collective behavior in a population.Recent evidence demonstrates their roles in plant root growth and defense responses.AtMYB44 is a multifaceted transcriptional factor that functions in many physiological processes
