PPS — Arabidopsis thaliana

Summary

AT2G42620, also known as MAX2, PPS, or ORE9, encodes an F-box and leucine-rich repeat-containing protein with transcription regulator activity and DNA-binding activity. In Arabidopsis, MAX2 is associated with strigolactone perception, response to karrikin, and detection of parasitic plants. The gene is linked to regulation of shoot morphogenesis, axillary branching, bud dilation, and secondary growth. It has been associated with drought tolerance, abscisic acid breakdown, glutathione and flavonoid anabolism, and hydrogen peroxide biosynthetic process. MAX2 is also associated with phloem development, tracheary element differentiation, and SCF complex assembly. The protein localizes to the nucleus, cytoplasm, SCF complex, and condensed nuclear chromosome. Related genes in other species link it to disease resistance and fruit quality traits such as ascorbic acid and soluble sugar content.
