Pollen grain of barley (Hordeum vulgare L.) - pattern of development
Acta Societatis Botanicorum Poloniae, 2014 Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

Legume Science, Volume 8, Issue 3, September 2026.ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

The Influence of pH on Microspore Embryogenesis of White Cabbage (<i>Brassica oleracea</i> L.)
Notulae Scientia Biologicae, 2013 In vitro microspore culture is one of the top techniques utilised now-a-days for the obtaining of double haploid plants in many plant species, including Brassica. The pH of the medium is a critical factor for the success of In vitro microspore culture as

Frontiers in Plant Science, 2015 Microspores are reprogrammed by stress in vitro towards embryogenesis. This process is an important tool in breeding to obtain double-haploid plants. DNA methylation is a major epigenetic modification that changes in differentiation and proliferation. We

Molecular insights and translational opportunities to enhance heat tolerance in rice
The Plant Genome, Volume 19, Issue 3, September 2026.Abstract Heat stress is an increasingly serious threat to rice (Oryza sativa L.) productivity, yet the genetic and regulatory architecture underlying thermotolerance remain poorly resolved and fragmented across studies. Earlier research focused on individual pathways or specific developmental stages; however, recent advances now support an integrated ...

Comparison of methods for obtaining doubled haploids of carrot
Acta Societatis Botanicorum Poloniae, 2017 Doubled haploid lines of carrot can be obtained through androgenesis in anther cultures and in isolated microspore cultures. The two methods were compared using three carrot cultivars (‘Kazan F1’, ‘Feria F1’, and ‘Narbonne F1’) at the androgenesis ...

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 ...

Cytological development, calcium dynamic and metabolite profile of stress-induced tobacco (Nicotiana tabacum L.) microspore under calcium chloride treatment [PDF]
Brazilian Journal of BiologyExogenous calcium is pivotal in activating microspore embryogenesis via calcium signaling. Altering the external calcium levels in the medium has been documented to impact the success rate of microspore embryogenesis initiation.

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 ...
