G3: Genes, Genomes, Genetics, 2018 In barley, it is possible to induce embryogenesis in the haploid and uninucleate microspore to obtain a diploid plant that is perfectly homozygous. To change developmental fates in this fashion, microspores need to engage in cellular de-differentiation ...

The incredible vulnerability that reproduction poses for plant species in a warming world
New Phytologist, Volume 251, Issue 6, Page 3111-3118, September 2026.Generalized plant responses to heat stress across whole‐plant and reproductive scales. Summary Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival ...

Spatially Resolved ABA Signalling Reveals Dual Role in Tomato Yield
Plant Biotechnology Journal, Volume 24, Issue 9, Page 5224-5235, September 2026.ABSTRACT Abscisic acid (ABA) is a central hormonal regulator of plant adaptation to stress and developmental progression. However, its contribution to agronomic traits such as yield remains unclear due to the pleiotropic nature of ABA signalling. To disentangle distinct physiological functions of ABA, we employed a receptor‐specific gain‐of‐function ...

Impact of Ionic Liquids on Induction of Wheat Microspore Embryogenesis and Plant Regeneration
Agronomy, 2020 Ionic liquids are novel compounds with unique chemical and physical properties. They can be received based on synthetic auxins like 2,4-dichlorophenoxyacetic acid or dicamba, which are commonly used hormones in microspore embryogenesis.

Genomics is modifying our concepts of evolution in homosporous and heterosporous vascular plants
American Journal of Botany, Volume 113, Issue 8, August 2026.Abstract Across the tree of life, and particularly within land plants, there is a wide diversity and disparity of genome structure. The most well‐studied are angiosperms, comprising mostly small and dynamic genomes, with a history of ancient whole genome duplications.

Clinical and Translational Allergy, Volume 16, Issue 8, August 2026.ABSTRACT Background Airway allergies affect 20%–30% of the global population, with pollen and fungal spores representing major environmental triggers. Although fungal spores are far more abundant than pollen, their allergenic role—particularly from phytopathogenic rust fungi such as birch rust (BR)—remains poorly understood.

Differential Expression Profiling Reveals Stress-Induced Cell Fate Divergence in Soybean Microspores
Plants, 2020 Stress-induced microspore embryogenesis is a widely employed method to achieve homozygosity in plant breeding programs. However, the molecular mechanisms that govern gametophyte de- and redifferentiation are understood poorly.

Microspore embryogenesis in Apiaceae
Plant Cell, Tissue and Organ Culture (PCTOC), 2010 Haploid technology is used to develop uniform, true-breeding lines, as well as to accelerate crop improvement programs. Among 20 Apiaceae species screened for response to doubled haploidy, 11 generated microspore-derived embryos, and all but one of the latter yielded doubled haploid plants.
