tended toward significanceP = 0.07
Although neither loss of Pp CLV1 nor Pp RPK2 displayed statistically significant interactions with Pp CHK loss of function, a negative interaction between Ppclv1 and Ppchk mutations tended toward significance ( clv1:chk P = 0.07; rpk2:chk P = 0.11), weakly supporting a role for PpCLV1 upstream of cytokinin.
