The Plant Journal, Volume 125, Issue 2, January 2026.SUMMARY The molecular and genetic mechanisms regulating female germline development remain largely unknown in basal and early‐divergent angiosperms. This contrasts with recent progress in model eudicots such as Arabidopsis thaliana and monocots, such as rice, barley, and maize. In this study, we investigate the genetic pathway governing female germline

Development of the male generative sphere in Jasminum nudiflorum Lindl. (Oleaceae)
Учёные записки Казанского университета: Серия Естественные науки, 2018 To reveal the causes for absence of fruits and seeds in Jasminum nudiflorum Lindl. (Oleaceae) in the Southern Coast of the Crimea, the male generative sphere genesis has been studied and the male gametophyte state during the period of mass blossoming has

The Plant Journal, Volume 125, Issue 2, January 2026.SUMMARY Cytokinins regulate diverse aspects of plant development. They are perceived by membrane‐localised receptors that transmit a signal to nuclear‐localised response regulators via the Histidine Phosphotransfer proteins (HPts). These HPts can be divided into two classes: authentic HPts (AHPs), which positively regulate cytokinin signalling, and ...

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.ABSTRACT Pollenkitt, the lipid‐rich coating of pollen grains, is a promising natural ultraviolet (UV)‐protective source rich in phenolic and flavonoid compounds. This study assessed the UV protection capacity of pollenkitt extracted from Narcissus tazetta using six solvents (dH2O, acetone, diethyl ether, ethanol, chloroform, and methanol).

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics
New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their
