Single‐Cell Transcriptome Atlas and Regulatory Dynamics in Developing Cotton Anthers

Advanced Science
Plant anthers are composed of different specialized cell types with distinct roles in plant reproduction. High temperature (HT) stress causes male sterility, resulting in crop yield reduction. However, the spatial expression atlas and regulatory dynamics

Primary Somatosensory to Motor Cortex Microstructural Connectivity Predicts the Mu‐Rhythm Phase Effect on Corticospinal Excitability: An EEG‐TMS Study

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.
Sensorimotor mu‐rhythm phase modulates corticospinal excitability; however, the influence of mu‐phase varies across individuals and could be related to microstructural connectivity between primary somatosensory (S1) and motor (M1) cortices. Our findings suggest that higher S1–M1 microstructural connectivity is associated with a stronger mu‐phase effect

Tapetum and middle layer control male fertility in Actinidia deliciosa

, 2013
Dioecism characterizes many crop species of economic value, including kiwifruit (Actinidia deliciosa). Kiwifruit male sterility occurs at the microspore stage. The cell walls of the microspores and the pollen of the male-sterile and male-fertile flowers,

TGMS in Rapeseed (Brassica napus) Resulted in Aberrant Transcriptional Regulation, Asynchronous Microsporocyte Meiosis, Defective Tapetum, and Fused Sexine

Frontiers in Plant Science, 2017
The thermo-sensitive genic male sterility (TGMS) line SP2S is a spontaneous rapeseed mutation with several traits that are favorable for the production of two-line hybrids.

Modified vehicle lighting reduces wildlife collision risk by enhancing deer and wild pig avoidance responses at night

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Generally, LED headlights had neutral or beneficial effects on wildlife responses, suggesting they could reduce collisions given the increased illumination levels they provide drivers. Additionally, our results support previous research indicating increased frontal vehicle illumination can reduce dangerous encounters with wildlife. Our findings suggest

Unresolved issues in pre-meiotic anther development

Frontiers in Plant Science, 2014
Compared to the diversity of other floral organs, the steps in anther ontogeny, final cell types, and overall organ shape are remarkably conserved among Angiosperms.

OsFKBP20‐1b stabilizes OsUPF1 and OsUPF2 to promote the degradation of aberrant mRNAs during dehydration stress

Journal of Integrative Plant Biology, Volume 68, Issue 6, Page 1672-1691, June 2026.
The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

The Tapetum: cytology, function, biochemistry and evolution

, 1993
The anther tapetum, present in all land plants, is a highly specialized, transient tissue surrounding the (micro-)spores and/or pollen grains during their development.Any tapetum malfunction causes male sterility.

Pollen, tapetum and orbicule development in Modiolastrum malvifolium (Malvaceae) [PDF]

, 2007
• Background and Aims: Although orbicular functions are still a matter of debate, they are considered by most authors to be exclusively formed by a secretory tapetum.
