Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]

, 2013
Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.

A comprehensive proteome and phosphoproteome atlas across nine organs of the Chinese hamster

Animal Models and Experimental Medicine, EarlyView.
This study presents the first comprehensive proteome and phosphoproteome atlas of the Chinese hamster across nine organs (heart, liver, lung, kidney, spleen, cerebral cortex, skeletal muscle, stomach, and testis or ovary). A total of 14 219 proteins were identified in the proteome, with 11 828 phosphorylated proteins and 47 122 phosphorylation sites ...

Wheat-barley hybridization – the last forty years [PDF]

, 2013
Several useful alien gene transfers have been reported from related species into wheat (Triticum aestivum), but very few publications have dealt with the development of wheat/barley (Hordeum vulgare) introgression lines. An overview is given here of

Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

Animal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

Cell proliferation and differentiation kinetics during spermatogenesis in Hydra carnea [PDF]

, 1985
Spermatogenesis inHydra carnea was investigated. The cell proliferation and differentiation kinetics of intermediates in the spermatogenesis pathway were determined, using quantitative determinations of cell abundance, pulse and continuous labelling ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
