Abstract:: ... Embryo sac abortion is one of the major reasons for sterility in indica/japonica hybrids in rice. To clarify the causal mechanism of embryo sac abortion, we studied the female gametophyte development in two indica/japonica hybrids via an eosin B staining procedure for embryo sac scanning using confocal laser scanning microscope. Different types of abnormalities occurred during megasporogenesis and ...

Abstract:: ... Hybrid sterility of the heterogametic sex is one of the first postzygotic reproductive barriers to evolve during speciation, yet the molecular basis of hybrid sterility is poorly understood. We show that the hybrid male sterility gene Odysseus-site homeobox (OdsH) encodes a protein that localizes to evolutionarily dynamic loci within heterochromatin and leads to their decondensation.

In this article, we show that BPMs can also assemble w ...

Abstract:: ... The collection of Cola nitida in Côte d'Ivoire was previously classified, based on isozyme markers, into three groups named A, B and C, based on isozymic differences. In this study, morphological traits and several yield components as well as genotypic and phenotypic variabilities for vigour were investigated in groups A and B. We found that group A was characterized by a low vigour and high yield ...
