The function of the tapetal tissue during microsporogenesis in Lilium

Acta Societatis Botanicorum Poloniae, 2014
The main functional activity -of the tapetum in the Lilium anther is the synthesis of reserve lipids and carotenoid pigments. The fusion of these substances during tapetum desintegration results in the formation of pollenkitt Pollernkitt participates in ...

Anatomical Associations Between Focal Mitochondrial Metabolism and Patterns of Neurodegeneration in Amyotrophic Lateral Sclerosis

Annals of Neurology, Volume 99, Issue 3, Page 614-628, March 2026.
Objective Amyotrophic lateral sclerosis (ALS) has a very specific neuroimaging signature, but the molecular underpinnings of the strikingly selective anatomic involvement have not elucidated to date. Accordingly, a large neuroimaging study was conducted with 258 participants to evaluate associations between patterns of neurodegeneration and focal ...

Heat Shock Transcription Factor OsHsfc1a Enhances Rice Seedling Thermotolerance by Regulating OsMFT1 and Preserving Chloroplast Structure Under Heat Stress

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1898-1915, March 2026.
ABSTRACT High‐temperature stress severely threatens rice (Oryza sativa L.) growth and productivity, particularly during the seedling stage, making heat tolerance an essential breeding target. In this study, we identified the heat shock transcription factor OsHsfc1a as a positive regulator of thermotolerance in rice seedlings.
