additional information	the progeny of VPS34/vps34 heterozygous plants, harboring a T-DNA insertion, shows a segregation ratio of 1:1:0 for wild-type, heterozygous, and homozygous mutant plants, indicating a gametophytic defect. The abnormal segregation ratio is due to failure to transmit the mutant allele through the male gametophyte. A 2fold higher proportion of pollen grains in heterozygous plants are dead or show reduced numbers of nuclei compared to the wild-type, phenotype, overview. Pollen grains from VPS34/vps34 plants are defective in vacuolar reorganization following the first mitosis	Arabidopsis thaliana
