Development of pollen grain in yellow passion-fruit (Passiflora edulis f. flavicarpa; Passifloraceae)

Genetics and Molecular Biology, 2000
To clarify events occurring during pollen grain formation in yellow passion-fruit (Passiflora edulis f. flavicarpa), floral buds were collected at different stages of development. After bracket, petal and sepal removal the anthers were fixed, dehydrated,

Développement floral chez Eragrotis tef : dynamique des gamétophytogenèses

, 1985
A calendar of reproductive events is established in Eragrostis tef (Zucc.) Trotter, a sexual tetraploid Ethiopian cereal, using the microsporogenesis and microgametogenesis as reference scales to which the female gametophytogenesis is related.

Comprehensive analysis of Ogura cytoplasmic male sterility-related genes in turnip (Brassica rapa ssp. rapifera) using RNA sequencing analysis and bioinformatics.

PLoS ONE, 2019
Ogura-type cytoplasmic male sterility (Ogura-CMS) has been widely used in the hybrid breeding industry for cruciferous vegetables. Turnip (Brassica rapa ssp. rapifera) is one of the most important local cruciferous vegetables in China, cultivated for its

Repetitive DNA in the Architecture, Repatterning, and Diversification of the Genome of Aegilops speltoides Tausch (Poaceae, Triticeae)

Frontiers in Plant Science, 2018
The genome’s adaptability to environmental changes, especially during rapid climatic fluctuations, underlies the existence and evolution of species. In the wild, genetic and epigenetic genomic changes are accompanied by significant alterations in the ...

Phosphatidylinositol 4-phosphate 5-kinases 1 and 2 are involved in the regulation of vacuole morphology during Arabidopsis thaliana pollen development [PDF]

, 2016
The pollen grains arise after meiosis of pollen mother cells within the anthers. A series of complex Structural changes follows, generating mature pollen grains capable of performing the double fertilization of the female megasporophyte.
