General Information

General Information Comment Organism
malfunction single knockout mutants of isoforms APY6 and 7 display a minor change in pollen exine pattern without obvious change in fertility, while double knockout mutants of APY6 and 7 display severe defects in pollen exine pattern, deformed pollen shape and reduced male fertility Arabidopsis thaliana
physiological function isoforms APY6 and AtAPY7 play an important role in exine development of pollen grains, possibly through regulating the production of key polysaccharides needed for proper assembly of the exine layer Arabidopsis thaliana
