Mechanisms of Genic Male Sterility [PDF]
Crop Science, 1995 For normal sexual reproductive development, coordination must occur between both male and female organ ontogeny. An abnormality at any point in this process may lead to sterility. Classification of sterility can be divided into heritable and nonheritable sterility.

Taigu Genic Male-Sterile Wheat
, 1987 This book deals with the theoretical background and breeding methods of the single dominant male sterile gene, a spontaneous mutant discovered for the first time in wheat. The book is divided into three sections: the discovery of Taigu genic male-sterile

Genic male sterility increases rice drought tolerance
Plant Science, 2021Plant fertility and resistance to stress environments are antagonistic to each other. At booting stage, fertility is often sacrificed for survive in rice under abiotic stress. However, the relationship between fertility and resistance at molecular level remains elusive.

Environment‐sensitive genic male sterility in rice and other plants
Plant, Cell & Environment, 2022AbstractEnvironment‐sensitive genic male sterility is a type of male sterility that is affected by both genetic and environmental factors. Environment‐sensitive genic male sterile lines are not only used in two‐line hybrid breeding but are also good materials for studying plant−environment interactions.

Genetics of thermosensitive genic male sterility in rice
Euphytica, 1996Inheritance of thermosensitive genic male sterility (TGMS) in Norin PL12 and IR32364TGMS and their allelic relationship were studied from F1, F2 testcross (TC) and F3 generations of the crosses made with the two mutants and several fertile tester parents. F2, TC and F3 segregation behavior for pollen and spikelet fertility indicated that the TGMS trait

Analysis of genic male sterility in Brassica oleracea
Euphytica, 1993The male sterility system MS-1 of Brassica oleracea was studied in order to elucidate if nucleo-cytoplasmic interactions determine this system. Crosses of male sterile MS-1 genotypes with heterozygous MS-5 genotypes gave fully fertile F1 progenies. Selfing of seven F1 plants resulted in five F2 populations showing a 9:7 segregation ratio and two a 3:1 ...

Progress on genic male sterility gene in soybean.
Yi chuan = Hereditas, 2021Male sterility refers to the phenomenon that stamens cannot grow normally and produce viable pollen grains in plants. Hybrid seed production by taking advantage of the trait of male sterility is an effective and quick strategy to increase crop yield. Up to date, the yield of rice (Oryza sativa L.), maize (Zea mays L.), wheat (Triticum aestivum L.) and ...

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.

Planta, 2003
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
