ERECTA contributes to non-host resistance to Magnaporthe oryzae in Arabidopsis

Abstract

ERECTA controls both developmental processes and disease resistance in Arabidopsis. We investigated the function of ERECTA in non-host resistance to Magnaporthe oryzae in Arabidopsis. In the pen2 er mutant, penetration resistance and post-penetration resistance to M. oryzae were compromised. These results suggest that ERECTA is involved in both penetration and post-penetration resistance to M. oryzae in Arabidopsis.

SOBIR1 contributes to non-host resistance to Magnaporthe oryzae in Arabidopsis

“…[18][19][20][21][22][23] Recently, we have also shown that the RLK ERECTA is a positive regulator of NHR to M. oryzae in Arabidopsis. 24) In this study, we examined the function of BAK1 and SOBIR1 in NHR to M. oryzae in Arabidopsis.…”

SOBIR1 and AGB1 independently contribute to nonhost resistance to Pyricularia oryzae (syn. Magnaporthe oryzae) in Arabidopsis thaliana

“…We previously studied the genetic interactions involved in NHR to P. oryzae in Arabidopsis and found that AGB1, ERECTA, and SOBIR1, but not BAK1, are positive regulators of NHR to P. oryzae in Arabidopsis pen2-1 mutant plants [33,[37][38][39]. To elucidate the genetic interactions between these components controlling NHR to P. oryzae in Arabidopsis pen2-1 mutant plants, pen2-1 sobir1-12 agb1-2 and pen2-1 sobir1-12 bak1-4 triple mutants were generated and their NHR response to P. oryzae was analyzed.…”

“…To date, we have determined that AGB1, ERECTA, and SOBIR1, but not BAK1, function as positive regulators in NHR to P. oryzae in Arabidopsis pen2-1 mutants [33,[37][38][39]. Based on being identified as suppressors of bir1-1, recent reports suggest that SOBIR1, BAK1, and AGB1 function in a genetic pathway to control cell death and plant immunity [9,10,26].…”

Plant peptides in plant defense responses

“…Until now, ERECTA-mediated plant immunity pathway efficient rescues plants from infection of the fungus P. cucumerina, Verticillium longisporum, and Magnaporthe oryzae, the bacterium R. solanacearum, the oomycete Pythium irregular, etc. [40][41][42][43][44][45]…”
