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 ...

Coffee is one of the most important commercial crops grown in many countries. Each day all over the world, millions of coffee lovers enjoy drinking coffee. Judged by total volume, coffee is one of the leading commodities in the international trade. Currently, it provides revenue over $ US 10 billion annually to the producing countries, and work for an ...

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.

Most temperate fruit trees are characterized by a long reproductive cycle with several years of a juvenile phase, a tendency to allogamy and a large tree size. They are generally highly heterozygous, outbreeding species, which are asexually propagated. For these reasons, their genetic improvement by conventional methods is time-consuming and limited by

Both Lolium perenne and L. multiflorum are strong outbreeders that exhibit severe inbreeding depression (Bean & Yok-Hwa, 1972; Matzk, 1974) and possess a strict gametophytic self-incompatibility system which involves two major gene loci with modification by the genetic background (Lawrence et al., 1983).

Plants having a single genome are known as haploids. Alternatively, haploid plants also are defined as those that have the gametic number of chromosomes. However, in the case of a polyploid species like alfalfa (Medicago sativa L.), a tetraploid with 2n = 4x = 32, haploid plants actually are true diploids with two homologous sets of chromosomes (2n ...

Rice (Oryza sativa L; 2n = 2x = 24) belongs to family Gramineae and the genus Oryza which includes 24 recognized species, of which 22 are primitive and the remaining two, O. sativa and O. glaberrima Steud., are cultivated. All the rice cultivars grown in Asia, Europe and America are O.

Mosaic paternal haploidy in a patient with pancreatoblastoma and Beckwith–Wiedemann spectrum
American Journal of Medical Genetics. Part A, 2019Pancreatoblastoma is a rare type of pancreatic cancer in children. Here, we describe a case in which Beckwith‐Wiedemann syndrome (BWS) was first suspected because of placental mesenchymal dysplasia.

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.
