Engineering a Gibberellin‐Switchable Dual‐Use Line Based on Ent‐Kaurene Oxidase Gene ZmKO1 Enables Two‐Line Hybrid Seed Production in Maize

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 4361-4377, June 2026.
ABSTRACT Male‐sterile systems are pivotal for maize hybrid seed production, yet existing systems are constrained by significant limitations. Here, we identified a novel single‐gene‐controlled recessive genic male sterility (GMS) mutant, defective in filament elongation 1 (def1), which exhibits non‐elongated filaments, unopened glumes, and non‐exserted ...

The function of the tapetal tissue during microsporogenesis in Lilium

open access: yesActa 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 ...

Plant Peptides on the Rise: From Historical Insight to Future Applications

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3777-3802, June 2026.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

A Comparative Study on Tapetum

open access: yesCYTOLOGIA, 1962
1. Division synchronization being taken as criterion, different cases of tapetum are classified into three types: 1) synchronized type, 2) asynchronized type and 3) intermediate type.3). In the synchronized type second division takes place and further divisions may also occur.
