Transcript level changes of genes involved in TDIF/PXY/WOX4 pathway and vascular development markers in wild-type Arabidopsis and various mutants and overexpressors. (A) Gene expression levels analyzed by qPCR in the hypocotyls of 5-week-old wild-type Arabidopsis and mutants under long-day conditions; (B) Change in gene expression level in the basal stem part of two 51-day-old PXC1 mutants after the long-day to short-day shifting experiment; (C) Relative CLE44 expression level measured by qRT-PCR in Col-0 and three CLE44 ox plants with inflorescence stems as tall as 15 cm; (D) Relative expression level of marker genes in wild-type and three CLE44 ox lines with inflorescence stems as tall as 15 cm.
