Meiotic prophase in Diplopoda
(1990-12-01)
Crosstalk Between Retinoic Acid and Sex-Related Genes Controls Germ Cell Fate and Gametogenesis in Medaka
(Frontiers Media Sa, 2021-01-18)
Sex determination (SD) is a highly diverse and complex mechanism. In vertebrates, one of the first morphological differences between the sexes is the timing of initiation of the first meiosis, where its initiation occurs ...
Meiosis aspects and nucleolar activity in Triatoma vitticeps (Triatominae, Heteroptera)
(SpringerDordrechtHolanda, 2006)
Analysis of Phalaenopsis Bud Length during Meiosis to Predict Pollen Fertility
(2017-03)
Phalaenopsis orchids are a very important commercial crop in tropical countries. Nonetheless hybrids feature variations in pollen fertility due to widespread chromosomal rearrangements in meiotic chromosomes. Usually each ...
Meiosis Research in Orphan and Non-orphan Tropical Crops
(2019-03-05)
Plant breeding is directly linked to the development of crops that can effectively adapt
to challenging conditions such as soil nutrient depletion, water pollution, drought, and
anthropogenic climate change. These ...
Control of oocyte maturation
(2014-01-01)
Oocyte maturation is a complex process involving nuclear and cytoplasmic maturation. The nuclear maturation is a chromosomal segregation and the cytoplasmic maturation involves the reorganization of the cytoplasmic organelles, ...
Control of oocyte maturation
(Brazilian Coll Animal Reproduction, 2014-07-01)
Oocyte maturation is a complex process involving nuclear and cytoplasmic maturation. The nuclear maturation is a chromosomal segregation and the cytoplasmic maturation involves the reorganization of the cytoplasmic organelles, ...
The ultrastructure of the pre-meiotic and meiotic stages of spermatogenesis in Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae)
(2002-04-01)
Spermatogenesis of 'corvina' P. squamosissimus starts from a stem cell that gives rise to germ cells. These cells are enveloped by Sertoli cells, forming cysts. The germ cells in the cysts are all at the same stage of ...
Cytogenetic analysis in the spermatogenesis of Triatoma melanosoma (Reduviidae; Heteroptera)
(2008-07-30)
Triatomines are of great concern in public health because they are vectors of Chagas' disease. This study presents an analysis of the species Triatoma melanosoma. The cytogenetic characteristics of triatomines include ...
