Abstract
The development of male gametophytes in diploid and monosomic-1, -2, -3, -4, -6, -7, -8, -9, and -10 maize plants was characterized. Developmental differences due to nullisomy in the gametophyte were evaluated by comparing the development of haploid and nullisomic microspores formed by monosomic plants, while differences due to gene dosage in the sporophyte were evaluated by comparing the development of haploid microspores in monosomic plants with those in diploids. These analyses show that (i) male gametophytes nullisomic for the chromosomes analyzed are developmentally delayed and eventually abort; (ii) male gametophytes nullisomic for chromosome 2 or 6 can reach the first mitosis, but those nullisomic for chromosomes 1, 3, 4, 7, 8, 9, or 10 do not reach the first division; and (iii) monosomy of chromosome 1, 2, 3, 4, 6, 7, 8, or 9 interferes with normal male gametophyte development, and monosomic-2 and -9 plants specifically cannot support pollen maturation.
