Cotton is an important economic crop, used mainly for the production of textile fiber. Using a space mutation breeding technique, a novel photosensitive genetic male sterile mutant CCRI9106 was isolated from the wild-type upland cotton cultivar CCRI040029. To study the male sterile mechanisms of CCRI9106, histological and iTRAQ-facilitated proteomic analyses of anthers were performed. This data...

Sexual reproduction in flowering plants depends on the evocation of flowers, which, in general, consist of four whorls of organs: sepals, petals, anthers, and pistil. Sepals and petals can be regarded as initially protective organs. During the first stage of floral development, meiosis occurs in the anthers and the pistil while these organs are still enclosed by the sepals. Petals, the organs o...

Rothia Pers. is a genus of papilionoid legumes that consists of two species, R. indica (L.) Druce and R. hirsuta (Guill. & Perr.) Baker. The genus is amember of the tribe Crotalarieae and is widely distributed inAfrica, Asia andAustralia. Recent molecular systematic studies have shown the genus to be closely related to RobynsiophytonWilczek and Pearsonia Dümmer; however, it is easily distinguis...

We compared microsporogenesis and flower development in Eucalyptus urophylla × E. tereticornis. In this study, although microsporogenesis and cytokinesis occurred simultaneously during meiosis of pollen mother cells, we observed a strong asynchronism in different anthers from a flower bud. The developmental period of microsporogenesis in anthers originated from the long thrum before the short t...

Eriocaulon meenachilense, a new species of the family Eriocaulaceae from southern Western Ghats, India, is described and illustrated. The similar to idukkianum E. tuberiferum but differs in its short, linear-subulate, stiff leaves, solitary 6-angled peduncle, inflexed involucral bracts, eglandular petals, yellow anthers seeds.

Passion fruit plants are self-incompatible and fruiting is exclusively dependent on cross-pollination, which in nature performed by carpenter (mamangava) bees, especially Xylocopa spp. (family Apidae). To ensure satisfactory productivity, daily manual pollination a common practice among passionflower growers. Therefore, we studied whether mechanically transmits the cowpea aphid-borne mosaic vir...

Beet is considered a difficult breeding object due to its biological peculiarities that make it obtain hybrid seed progeny. In cross-pollinated crops, the maximum hybridization achieved by using sterile mother plants, which are extremely rare in nature. Inbreeding one of ways isolate genotypes with cytoplasmic male sterility, controlled recessive alleles nuclear genes and S-factor mitochondrial...

We report cell-to-cell movement of mitochondria through a graft junction. Mitochondrial movement was discovered in an experiment designed to select for chloroplast transfer from Nicotiana sylvestris into Nicotiana tabacum cells. The alloplasmic N. tabacum line we used carries Nicotiana undulata cytoplasmic genomes, and its flowers are male sterile due to the foreign mitochondrial genome. Thus, ...

A novel genetic male sterile germplasm was developed by successively crossing of (C. annuum x C. chinense) x C. pubescens and by chemical mutagenesis in pepper. The sterile anthers showed morphological abnormalities, but pistils developed normally with fine pollination capability. We investigated fertility segregation through sib-crossing of the same strains and test crossing by male sterile pl...
