WebSelf-incompatibility was controlled sporophytically by a pair of S alleles. All but two of the differential protein bands were completely correlated with S alleles, ... WebThe simple genetic basis of the natural variation and effects of single-gene mutations suggests that F1 lethality in polyploids could evolve rapidly. Furthermore, the role of the …

Incompatibility and Incongruity in Wild and Cultivated Plants

WebHomomorphic multi-locus sporophytically determined self-incompatibility systems are much rarer than multi-locus gametophytic systems. This note examines some of the possible reasons for this disparity and concludes that, while each additional locus in a gametophytic system allows increased crossing among related plants as well as a lower … WebDerivatives: sporophytic adj. sporophytically adv.

S-allele specificity of stigma proteins in Brassica oleracea

Web17 Jun 2013 · The formation of the female gametophyte is divided into two main steps, megasporogenesis and megagametogenesis [1], [2]. During megasporogenesis the Megaspore Mother Cell (MMC) undergoes meiosis and produces four haploid megaspores. WebIPCN-derived data, using the “Spor Count” (i.e., sporophytically derived count) column for ploidy inference; unique values in the “Gam Count” column were doubled and also used. For pri-mary literature-derived values, we favored the authors’ inference of ploidy when available. Within each clade, inference was generally –, – –, – Websporophytically controlled mechanism.
