To gain further insight into the abortive stages and ultrastructural changes leading to pollen degeneration of a novel cytoplasmic male sterile radish 805A, we compared differences of cellular and subcellular structure of sterile anther with fertile anther by light and electron microscopy analysis. Two types of locule degeneration in ...

A cytoplasm male sterile pepper (Capsicum annum L.) was examined using cytochemical method to study its pollen abortion. Thick sections of both anthers of male sterility line 8214A and its maintainer 8214B at different stages were stained using Periodic Acid-Schiff's (PAS) reaction to detect starch distribution. ...
Conflict/reconciliation between mitochondria and nuclei in plants is manifested by the fate of pollen (viable or nonviable) in the cytoplasmic male sterility (CMS)/fertility restoration (Rf) system. Through positional cloning, we identified a nuclear candidate gene, RETROGRADE-REGULATED MALE STERILITY (RMS) for Rf17, a fertility ...

About half of the 1.2 million abortions each year in the United States are repeat abortions. While most abortion providers counsel women about contraception, one reason for the high repeat rate could be failure to take into account the social context of the women--in particular, the male partner. To assess whether ...
Multispectral analysis combined with the Periodic Acid-Schiff method was used to investigate cytological features of insoluble polysaccharides and changes in total insoluble polysaccharide content (TPC) during pollen development in rice, including four cytoplasmic male sterility lines (MSLs) and their corresponding fertility-maintaining lines (FMLs). The ...
Men aged 18 to 35 years (n = 1318) completed assessments of perpetration of intimate partner violence (IPV), abortion involvement, and conflict regarding decisions to seek abortion. IPV was associated with greater involvement by men in pregnancies ending in abortion and greater conflict regarding decisions to seek ...
