Cytokinins in a genic male sterile line of Brassica napus
Physiologia Plantarum, 1992Endogenous cytokinin levels were analyzed in four different organs viz., root, stem, leaf and mature flower, of the wild type (cv. Westar) and a genic male sterile (GMS) line of Brassica napus. Various cytokinins viz., bases (Z, DZ), ribosides (ZR, DZR), glucosides (OGZ + OGZR, OGDZ + OGDZR) and nucleotides (ZNT, DZNT) were quantified using Amaranthus ...

Photoperiod-sensitive genetic male-sterile (PSGMS) rice, with its male fertility regulated by photoperiod length, is very useful for hybrid rice development. However, breeding for new PSGMS lines has faced two major difficulties - the stability of male sterility and the reversibility of male fertility.

Genic Male Sterility (g-mst) is of a wide occurrence in flowering plants and the majority of the steriles have arisen as spontaneous mutants (Table 2.1). Only a few have been induced after mutagen treatments (Table 2.3). In about 175 species in which mst has spontaneously arisen, the majority are dicots in species as well as in species crosses (Fig.

The tapetum plays a crucial role in pollen development. This secretory tissue produces numerous nutritive proteins necessary for pollen maturation. The tapetum, whose cells undergo programmed cell death (PCD), is completely diminished by the time the pollen is fully mature. Our previous studies on a thermosensitive genic male-sterile (TGMS) rice (Oryza

Molecular markers for genic male sterility in Chinese cabbage
Euphytica, 2003The gms gene of Chinese cabbage (Brassica campestris ssp. chinensis) conferring a recessivegenic male sterility was mapped with AFLPmarkers. Four markers were found to betightly linked to the gene with a distanceof

Cytochemical investigation of genic male-sterility in Chinese cabbage
Sexual Plant Reproduction, 2005A genic male sterile Chinese cabbage, Brassica campestris L. ssp. chinensis Makino, was examined using cytological and cytochemical methods to characterize the process of pollen abortion in this plant. Thick sections of both fertile and sterile anthers at different developmental stages were stained using Toluidine Blue O, Periodic Acid-Schiff’s (PAS ...

The male sterile plants that segregated in a BC5F2 of `C. sericeus × C. cajan var. TT-5' population were maintained by sib mating. The male sterile plants were crossed with ICPL-85012.Approximately 50% of the F1 plants were sterile. F2 plants derived from the fertile F1 plants did not segregate for male sterility. The reciprocal hybrid i.e. ICPL-85012 ×

Fertility alternation normally occurs in a novel type of thermo-photo-sensitive genic male sterile (TGMS) wheat whose recessive genes in the nucleus are expressed as virtually complete sterility under lower temperature and shorter daylight conditions, but as normal fertility under higher temperature and longer daylight conditions during the ...

Environment-sensitive genic male sterility (EGMS) in crops
2001Publisher Summary This chapter discusses environment-sensitive genic male sterility (EGMS) and its use in crops; particular emphasize is given on rice, but the principles and practices reported are applicable to other crops as well. The chapter also discusses the current status of and future outlook for the use of EGMS to develop and use two-line ...

Genic male sterility in tomato and its manipulation in breeding
1994Male sterility in plants is widely recognized as a useful trait in breeding programs and in the commercial production of F1 hybrid seed. Male sterile plants have been reported in a large number of families and genera, and in almost all of the major crop plants (Kaul 1988). Although most known male sterile lines are of natural occurrence, male sterility
