Webcryptic bract (CB). The blue domain represents cryptic bract tissue. b The ‘‘bulging in the shallow crease’’ stage in a P3 primordium where the FM initiates in the crease of the bract axil, thereby creating a second crease between FM and IM. c Outgrowth of the FM incorporates the bulge of the cryptic bract and eradicates the crease at WebResults and discussion. ULT1 is required to regulate both cell division rate and auxin signaling in the root apical meristem. 19 Whether ULT1 contributes to DNRR is still unknown. To address this question, we examined rooting rate and root regeneration capacity by culturing leaf explants on B5 medium without exogenous hormone treatment … WebMay 29, 2009 · Subsequent development of the cryptic bract is strongly suppressed by an unidentified signal derived from the floral meristem ( Nilsson et al., 1998; Long and Barton, 2000 ), resulting in the formation of a flower that lacks a visible subtending bract. greenville sc nurseries and greenhouses
