THE occurrence of microspores in centric diatoms and their possible nature have been the objects of great discussion. Recently, Gross1, on the basis of cultures of Chaetoceros pseudocrinitus and Ch. didymus, concluded that “there is no evidence whatever that these microspore-like bodies found in the cultures of Ch.

Since androgenesis involves the control and reprogramming of developmental switches, it provides opportunities to investigate key elements in developmental control. Moreover, via androgenesis, fertile homozygous progeny from a heterozygous parent can be obtained in a single generation, thus significantly reducing time required in breeding programs and ...

Cauliflower ( Brassica oleracea var. botrytis L.) is an important vegetable grown throughout the world. In India, wide diversity exists in cauliflower in terms of their adaptation to different temperature and maturity duration.

Microspore Culture in Brassica
2003Pioneering research in Brassica microspore culture (1,2,3)rapidly led to the realization that microspores provide a powerful alternative to protoplast culture as a single-celled culture method in plants. These two single-celled systems are fundamentally different, both in tissue origin and in genetic variability.

Mechanical isolation of Brassica napus microspores from whole buds with a micro-blender enabled the rapid isolation of large numbers of microspores free from tissue and cellular debris. The procedure resulted in savings of time and labor and could be used independent of the size and number of buds to be examined.

MICROSPORE CULTURE IN ELEVEN CULTIVARS OF LOQUAT
Acta Horticulturae, 2015In plant breeding, microspore embryogenesis via isolated microspore culture is increasing as a method to obtain in a single-step doubled haploids and homozygosity. In this study, isolated microspore culture of eleven cultivars of loquat (Eriobotrya japonica (Thunb.) Lindl.) has been carried out.

The microspore: A haploid multipurpose cell
2001Abstract The microspore is at the centre of a variety of topics in modern plant science and breeding. Isolated microspore cultures have the remarkable quality of resembling the alternation of generations in the life cycle of angiosperms, i.e. the change between the diploid sporophytec and the haploid gametophytec generation.

The maize pollen grain represents the beginning of a short-lived gametophytic phase during which the two sperm are delivered to the embryo sac prior to fertilization. Although this stage of the life cycle normally consists of only a few cell divisions, under certain experimental conditions, gametophytes can be induced to undergo an altered development,

THE EXTENSIVE USE of Tradescantia paludosa as experimental plant material, especially in investigations involving the first microspore division in which radiations, gases and chemical substances were used, has necessitated a more detailed study of the morphological stages and the nuclear cycle in the developing microspore, including a time sequence ...
