Tapetum-Dependent Male Meiosis Progression in Plants: Increasing Evidence Emerges
Frontiers in Plant Science, 2020 In higher plants, male meiosis is a key process during microsporogenesis and is crucial for male fertility and seed set. Meiosis involves a highly dynamic organization of chromosomes and cytoskeleton and specifically takes place within sexual cells ...

A Century of Understanding and Harnessing Heterosis
Plant Breeding, EarlyView.ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Techniques for subretinal injections in animals
Veterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...

Конкурентное и кооперативное поведение клеток в микроспорогенезе покрытосеменных
Фактори експериментальної еволюції організмів, 2016 Aim. A comparative cytological analysis of intra- and intertissue cytomictic interactions in early microsporogenesis of mono- and dicotyledonous plants was performed using two cellular systems: microsporocytes and tapetum. Methods.

Clinical Case Reports, Volume 14, Issue 10, October 2026.ABSTRACT Arachnoid cysts are most commonly asymptomatic and usually do not need any active treatment. Currently, psychiatric symptoms are seldom taken into consideration during treatment evaluations in this patient population. We present this case of a young man who was treated in our hospital for signs of depression.

Structure and development of male gametophyte in Carya illinoensis (Wangenh.) K. Koch
Caryologia, 2019 In order to understand the differentiation of staminate flowers of pecans (Carya illinoensis (Wangenh.) K. Koch), we carried out an integrated study of staminate flower development in a protogynous cultivar, Mahan, by assessing changes in external ...

Graft Biology in the CRISPR Era: From Tissue Fusion to Genome Compatibility
Plant-Environment Interactions, Volume 7, Issue 5, October 2026.ABSTRACT Plant lineage has traditionally constrained grafting compatibility, with monocots generally considered incompatible because of their dispersed vascular bundles and limited secondary growth. Recent studies have shown that embryonic grafting can establish successful graft unions in selected monocot systems by exploiting early developmental ...

Journal of Avian Biology, Volume 2026, Issue 5, September 2026.Animals use a variety of environmental cues to identify profitable conditions and increase their foraging efficiency. Identifying environmental correlates of foraging behaviour can help to understand the drivers of animal foraging decisions, and the potential consequences should conditions change.
