OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

Plant Biotechnology Journal, EarlyView.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

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

Plant Biotechnology Journal, EarlyView.
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 (

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

Functional characterization and expression of GASCL1 and GASCL2, two anther-specific chalcone synthase like enzymes from Gerbera hybrida [PDF]

, 2017
The chalcone synthase superfamily consists of type III polyketidesynthases (PKSs), enzymes responsible for producing plant secondary metabolites with various biological and pharmacological activities. Anther-specific chalcone synthase-like enzymes (ASCLs)

Linking Superoxide Production and Scavenging in Plant Development

Plant, Cell &Environment, EarlyView.
ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

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.

Fragments of the earliest land plants [PDF]

, 2003
The earliest fossil evidence for land plants comes from microscopic dispersed spores. These microfossils are abundant and widely distributed in sediments, and the earliest generally accepted reports are from rocks of mid-Ordovician age (Llanvirn, 475 ...

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.

What horses and humans see: a comparative review [PDF]

, 2009
Adaptations of the mammalian eye have tailored each to its own particular ecological niche. On the one hand, it would appear that the horse is best served by a system that can keep "half an eye" on everything, while the human benefits from focussing on ...

Techniques for subretinal injections in animals

Veterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...
