A general stochastic model for sporophytic self-incompatibility [PDF]

, 2011
Disentangling the processes leading populations to extinction is a major topic in ecology and conservation biology. The difficulty to find a mate in many species is one of these processes.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Assessment of Cassava Pollen Viability and Ovule Fertilizability under Red-Light, 6-Benzyl Adenine, and Silver Thiosulphate Treatments

Plants
Understanding pollen and ovule fertility as factors influencing fruit and seed set is important in cassava breeding. Extended daylength with red light (RL) and plant growth regulators (PGRs) have been used to induce flowering and fruit set in cassava ...

Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...

The Arabidopsis INNER NO OUTER (INO) gene acts exclusively and quantitatively in regulation of ovule outer integument development

Plant Direct, 2023
The INNER NO OUTER (INO) gene is essential for formation of the outer integument of ovules in Arabidopsis thaliana. Initially described lesions in INO were missense mutations resulting in aberrant mRNA splicing. To determine the null mutant phenotype, we

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Single-cell RNA-seq reveals a link of ovule abortion and sugar transport in Camellia oleifera

Frontiers in Plant Science
Camellia oleifera is the most important woody oil crop in China. Seed number per fruit is an important yield trait in C. oleifera. Ovule abortion is generally observed in C. oleifera and significantly decreases the seed number per fruit.

Exploration of Limonium interspecific breeding possibility : a thesis presented in partial fulfilment of the requirement for the degree of Master of Science in Plant Science at Massey University, Palmerston North, New Zealand [PDF]

, 1995
Interspecific crossability was investigated in the genus Limonium (Plumbaginaceae). Six Limonium species were chosen for this study, five of which are dimorphic and L.perigrinum which is monomorphic.

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...
