malfunction | loss-of-function mutations in hydroxyproline O-arabinosyltransferase-encoding genes cause pleiotropic phenotypes that include enhanced hypocotyl elongation, defects in cell wall thickening, early flowering, early senescence and impaired pollen tube growth | Arabidopsis thaliana |
physiological function | essential role of Hyp O-arabinosylation in both vegetative and reproductive growth (hypocotyl elongation, cell wall thickening, flowering, senescence and pollen tube growth) | Arabidopsis thaliana |
