Aggregations of organelles in meiotic cells of higher plants

Acta Societatis Botanicorum Poloniae, 2014
During early prophase I in microsporocytes and sporocytes of various plants all mitochondria and plastids aggregate in a group, where some plastids seem to undergo division. This group desintegrates by middle prophase I.

Characterization of Japanese Apricot (Prunus mume) Floral Bud Development Using a Modified BBCH Scale and Analysis of the Relationship between BBCH Stages and Floral Primordium Development and the Dormancy Phase Transition

Horticulturae, 2021
Bud dormancy is an important developmental stage that ensures that trees can tolerate environmental stresses in winter and bloom uniformly in the following spring. Regarding Rosaceae floral buds, exposure to chilling conditions promotes floral primordium

Advancing Thermotolerance in Beans: Integrating Physiology, Genomics, and Breeding for Climate Adaptation

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 ...

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 ...

ERECTA‐family receptor kinases: versatile regulators of plant developmental signaling

The Plant Journal, Volume 125, Issue 6, March 2026.
Significance Statement How plant cells coordinate developmental patterning remains a fundamental question in biology. This review synthesizes current knowledge of how ERECTA‐family receptors interpret spatiotemporal peptide cues to regulate diverse developmental processes, highlighting mechanisms of receptor activation, signal transduction, subcellular

Imaging of Molecular and Developmental Responses to Abiotic Stresses in Reproductive Tissues

Physiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stresses, such as drought, salinity, and extreme temperatures, have profound effects on plant reproduction, often leading to reduced fertility and yield. Reproduction in plants involves complex interactions between diverse cells, necessitating spatiotemporal resolution to understand how stress impacts each component of this intricate ...
