Microsporogenesis and pollen sulcus type in Asparagales (Lilianae)

, 1997
Cladistic analysis of molecular data (plastid rbcL sequences) supports the interpretation of simultaneous microsporogenesis as an apomorphy for Asparagales (Lilianae), with a reversal in the most derived 'higher' asparagoid clade, which is entirely ...

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

Microtubule organization during successive microsporogenesis in Allium cepa and simultaneous cytokinesis in Nicotiana tabacum

, 2011
Microtubule cytoskeleton organization during microspore mother cell (MMC) meiosis in Allium cepa L. and microsporogenesis in Nicotiana tabacum L. was examined. The MMC microtubules (MTs) were short and well dispersed in the cytoplasm of both taxa. As the

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 ...

Multi‐Level Approaches for Assessing Molecular and Physiological Traits of Drought and Heat Stress Tolerance in Plant Reproductive Development

Physiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stress, particularly heat and drought, significantly impacts plant reproductive development, threatening crop productivity and food security. Understanding stress tolerance mechanisms requires a multi‐level approach that integrates physiological, biochemical, and molecular traits in different experimental settings. This review explores
