Seven genes encoding PLCs form tomato were identified.
Recombinant tomato PLC proteins showed typical PLC activity.
Tomato PLC2, PLC4 and PLC5 showed distinct requirements for Ca2 + ions and the pH.
The activity of each tomato PLC enzyme is probably differentially regulated in vivo.
The response to flg22 as well as FLS2 endocytosis are suppressed by inhibition of PLC activity.
