A biotechnology‐based male‐sterility system for hybrid seed production in tomato

open access: yesThe Plant Journal, 2020
Summary Incorporating male sterility into hybrid seed production reduces its cost and ensures high varietal purity. Despite these advantages, male‐sterile lines have not been widely used to produce tomato (Solanum lycopersicum) hybrid seeds.

Impacts of climate change on rice production in Africa and causes of simulated yield changes [PDF]

open access: yes, 2019
This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland).

Alimentary infertility in female cattle: Part ІІ – the effect of macronutrients on reproductive function (Overview)

open access: yesTheoretical and Applied Veterinary Medicine, 2023
Macronutrients are direct participants in the most important biochemical processes, and their deficiency or excess leads to metabolic disorders, which, in turn, is a direct cause of infertility.

Male Sterility in Maize after Transient Heat Stress during the Tetrad Stage of Pollen Development1[OPEN]

open access: yesPlant Physiology, 2019
Short moderate heat stress during the tetrad stage of pollen development targets vital metabolic pathways, ultimately leading to sterility and yield losses in maize. Shifts in the duration and intensity of ambient temperature impair plant development and

A novel strategy for creating a new system of third‐generation hybrid rice technology using a cytoplasmic sterility gene and a genic male‐sterile gene

open access: yesPlant Biotechnology Journal, 2020
Summary Heterosis utilization is the most effective way to improve rice yields. The cytoplasmic male‐sterility (CMS) and photoperiod/thermosensitive genic male‐sterility (PTGMS) systems have been widely used in rice production.

Reproductive Compatibility Within and Among Spruce Budworm (Lepidoptera: Tortricidae) Populations [PDF]

open access: yes, 2017
Spruce bud worm moths collected as larvae from two species of host trees in four populations were mated in single pairs in two years. In 1980 but not 1981, more of the intra-population matings than the inter-population matings were fertile.

Role of Adiponectin Hormone in Fertility and Sterility: A Systematic Review [PDF]

open access: yesMajallah-i Zanān, Māmā̓ī va Nāzā̓ī-i Īrān, 2018
Introduction: Adiponectin is a hormone from adipokine family, which releases from adipose tissue cells and has many biological roles. According to the literature, the level of this hormone reduces in obese individuals.

THBD sequence variants potentially related to recurrent pregnancy loss

open access: yesReproductive Biology and Endocrinology, 2017
Recurrent pregnancy loss (RPL) is a frequently occurring disease, which is classified as idiopathic in more than 50% of cases. THBD, the endothelial cell receptor for thrombin, has been associated with distinct biological processes and considered a ...

Influence of short-term ovarian stimulation on bone metabolism in women undergoing fertility treatment

open access: yesJournal of Laboratory Medicine, 2021
– FSH is an influencing factor on parameters of bone metabolism.– Short term rFSH/HMG-treatment does not significantly enhance parameters of bone resorption.– No significant difference between rFSH- und HMG-stimulation has been found.

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

open access: yes, 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.
