Grapevine is one of the most widely cultivated plants in the world and man has been growing it since the beginning of his recorded history. Despite this, haploid plants have never been observed in Vitis (Olmo, 1976), which would lead to the conclusion that haploidy, the ability to generate haploid (n) plants (sporophytes) rather than diploids (2n), is ...

Newly developed gynogenesis and androgenesis methods are described for tef. The diminutive floral structures of tef are problematic and have necessitated the development of spikelet culture and more effective treatments. Media composi- tion has been optimised.

Transition from haploidy to diploidy
Nature, 1991As a direct consequence of sex, organisms undergo a haploid and a diploid stage during their life cycle. Although the relative duration of haploid and diploid phases varies greatly among taxa, the diploid phase is more conspicuous in all higher organisms.

Near-haploidy in a case of plasmocytoma
Cancer Genetics and Cytogenetics, 1986Chromosome studies of a solitary plasmocytoma in the femoral bone revealed a near-haploid chromosome number of 31-32 with a loss of one homolog of each chromosome pair except #1, #7, #9, #15, #19-21, and the sex chromosomes (XY). The cytogenetic findings have been compared with 16 cases of near-haploid neoplasms from the literature studied using ...

Citrus fruits are cultivated in more than 80 countries and rank first among fruit crops for worldwide production with about 73 millions tons harvested annually (FAO, 1994). Citrus fruits are an important source of human nutrition. Due to lower production costs, the cultivation of Citrus in developing countries has increased from 50 to 65% of total ...

The genus Petunia was first established in 1803 and since then, 30 Petunia species have been described, originated from South America (Sink, 1984). Because of inconsistency in taxonomic data of different Petunia species, the exact origin of the cultivated Petunia hybrida (Fig. 1) is still unknown. Van der Krol & Chua (1993) speculated that P.
