Arabidopsis phospholipase Dβ1 modulates defense responses to bacterial and fungal pathogens

Zhao, Jian; Devaiah, Shivakumar P.; Wang, Cunxi; Welti, Ruth; Wang, Xuemin (2013-10-24)

[1] Pathogen infection of higher plants often induces rapid production of phosphatidic acid (PA) and changes in lipid profiles, but the enzymatic basis and the function of the lipid change in pathogen–plant interactions ...
Inter-relationship between sphingosine kinase and phospholipase D in signaling Arabidopsis response to abscisic acid

Guo, Liang; Mishra, Girish; Markham, Jonathan E.; Li, Maoyin; Tawfall, Amanda; Welti, Ruth; Wang, Xuemin (2012-05-21)

Phosphatidic acid (PA) and phytosphingosine-1-phosphate (phyto-S1P) both are lipid messengers involved in plant response to abscisic acid (ABA). Our previous data indicate that PA binds to sphingosine kinase (SPHK) ...
