Microspore developmental evaluation at the booting stage and androgenic callus induction in sorghum [Sorghum bicolor (L.) Moench] via anther culture

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Androgenesis is a key method for producing doubled haploid (DH) lines, typically achieved through in vitro techniques such as anther culture and isolated microspore culture.

Anther-derived microspore embryogenesis in pepper hybrids orobelle and Bomby

Botanical Studies
Background Traditional breeding methods have long been employed worldwide for the evaluation and development of pepper cultivars. However, these methods necessitate multiple generations of screening, line development, evaluation, recognition, and ...

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Evolution of molecular communication in the permanent Azolla symbiosis

New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Loss of E3 ligase HvST1 function substantially increases distal crossover frequency

New Phytologist, Volume 249, Issue 3, Page 1325-1341, February 2026.
Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.

Microspore embryogenesis in vitro: the role of stresses

Вавиловский журнал генетики и селекции, 2019
Gametic embryogenesis is one form of totipotency of plant cells, in which either male or female gametes are induced to form embryoids (sporophytes). Regeneration of haploid plants from embryoids and subsequent chromosome duplication result in doubled ...

The effect of phytosulfokine alpha on haploid embryogenesis and gene expression of Brassica napus microspore cultures

Frontiers in Plant Science
Microspore embryogenesis (ME) is the most powerful tool for creating homozygous lines in plant breeding and molecular biology research. It is still based mainly on the reprogramming of microspores by temperature, osmotic and/or nutrient stress.
