Plant Vascular Cell Division Is Maintained by an Interaction between PXY and Ethylene Signalling

ERF genes are required for the eto1 vascular phenotype.
(A) Graph showing cells per vascular bundle at the base of the inflorescence stem of 10 week Col, eto1, eto1 erf109, eto1 erf1 and eto1 erf109 erf1 plants. eto1 erf109 erf1 plants are significantly smaller than eto1 single mutants. (B) Graph showing hypocotyl diameter (mm) of Col, eto1 erf109, eto1 erf1 and eto1 erf109 erf1 plants at 10 weeks. ERF109 and ERF1 are required for increases in hypocotyl diameter observed in eto1. (A and B) * significantly smaller than eto1 (p<0.05); error bars are standard error.
