Maize Prolonged Prophase 1 is essential for meiotic progression in pollen mother cells

Crop Journal
Meiosis, a critical process for sexual reproduction, requires precise regulation to ensure the correct progression of meiotic stages. In yeast and animals, errors in meiotic recombination and homologous chromosomes synapsis bring a surveillance mechanism

Redundant Glycerol‐3‐Phosphate Acyltransferases Regulate Thermo‐Sensitive Genic Male Sterility in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Thermo‐sensitive genic male sterility (TGMS) lines play a pivotal role in two‐line hybrid rice breeding. However, the availability of elite TGMS germplasm remains limited, and the molecular mechanisms underlying fertility transition of TGMS lines are still poorly understood.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Crossability Relations of Domesticated Peas (Pisum sativum and Pisum abyssinicum) With Wild Pisum fulvum and Drought Response Assessment of P. sativum × P. fulvum Progenies

Plant Breeding, EarlyView.
ABSTRACT The productivity and quality of grain crops in semiarid environments is often affected by drought, which is likely to accentuate due to predicted climate changes. Wild pea (Pisum fulvum Sibth. & Smith) accessions are known to harbour useful allelic diversity for drought responses.

Male meiosis at the helm

The generation of haploid gametes is a hallmark of sexual reproduction achieved through a complex, albeit tightly regulated, reductional cell division known as meiosis. While the molecular underpinnings of meiosis have been extensively characterized in eutherian mammalian models, key aspects-particularly those governing chromosome synapsis and ...

Mitotic antipairing of homologous and sex chromosomes via spatial restriction of two haploid sets. [PDF]

, 2018
Pairing homologous chromosomes is required for recombination. However, in nonmeiotic stages it can lead to detrimental consequences, such as allelic misregulation and genome instability, and is rare in human somatic cells.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
