First Gynogenesis of Vanilla planifolia for Haploid Production and Ploidy Verification Protocol

Plants
Vanilla orchids are members of the Vanilloideae orchid subfamily, and they hold significant economic value as a spice crop in tropical regions. Despite the presence of 180 known species within this subfamily, commercial production focuses on only three ...

Combining ability of doubled haploids in Coffea canephora P. [PDF]

, 1994
Afin d'étudier leur aptitude à la combinaison, cinquante-cinq haploïde-doublées (HD) de #Coffea canephora$ ont été croisés avec soit des génotypes hétérozygotes soit des génotypes HD. Trois essais agronomiques ont été établis. Une vigueur hybride marquée

Efeitos de meios de cultura na formação de calos a partir de anteras de aspargo (Asparagus officinalis L.) Effects of the culture media on the calli formation from Asparagus officinalis L. anthers

Acta Botânica Brasílica, 1995
Técnicas auxiliares, como a cultura de anteras, possibilitam melhor eficiência na obtenção de novos genótipos de aspargo. Neste trabalho, foram utilizadas anteras contendo grãos de pólen, no estágio uninucleado, dos híbridos 56x22-8 e 47x22-8, em meio MS,

Replacement of the essential Dictyostelium Arp2 gene by its Entamoeba homologue using parasexual genetics [PDF]

, 2007
Background: Cell motility is an essential feature of the pathogenesis and morbidity of amoebiasis caused by Entamoeba histolytica. As motility depends on cytoskeletal organisation and regulation, a study of the molecular components involved is key to a ...

Effect of genotypic background on haploid production through embryo rescue in wheat × maize crosses - Short Communication

Plant, Soil and Environment, 2005
Two high yielding wheat (Triticum aestivum L.) varieties were pollinated with seven agrarian superior varieties. F1's thus obtained were pollinated with diverse winter maize lines/composites and treated with a solution containing 2,4-D and GA3.

Stable demographic ratios of haploid gametophyte to diploid sporophyte abundance in macroalgal populations.

PLoS ONE
Macroalgal populations often consist of free-living haploid (gametophyte) and diploid (sporophyte) stages. Various ecological studies have been conducted to examine the demographic diversity of haploid-diploid populations with regard to the dominant ...

USE OF CELL ENGINEERING FOR DEVELOPMENT OF THE CONSTANT INITIAL BREEDING MATERIAL OF WHITE HEAD CABBAGE CV. NADZEJA AND CMS SAMPLES

Овощи России, 2015
The anther derived androgenic plants of white head cabbage cv. Nadzeja and CMS samples were obtained. The cytological analysis of ploidy level of regenerated plants and doubled haploids obtained by treatment of meristems with colchicine was performed. On

Molecular evidence of the haploid origin in wheat (Triticum aestivum L.) with Aegilops kotschyi cytoplasm and whole genome expression profiling after haploidization [PDF]

, 2014
Aegiolops kotschyi cytoplasmic male sterile system often results in part of haploid plants in wheat (Triticum aestivum L.). To elucidate the origin of haploid, 235 wheat microsatellite (SSR) primers were randomly selected and screened for polymorphism ...
