Optimization of in vitro pollen storage conditions in seeded and low-seeded citrus genotypes

Environment Conservation Journal
An in vitro pollen storage study was conducted using pollen from three seeded citrus plant genotypes, viz., ‘Mexican lime’, ‘W’. Murcott’ and ‘Mosambi’ and five seedlesscitrus genotypes, viz., ‘Lisbon lemon’, ‘Jaffa’, ‘Clementine’, ‘Hamlin’ and ‘Mukaku ...

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Developing an Efficient System for Hybrid Rice Seed Production Using Partial Male Sterility. [PDF]

Plant Biotechnol J
ABSTRACT Efficient production of hybrid rice seeds requires male sterility systems to overcome the challenges of self‐pollination. In this study, we identified male gametic transfer defect (GTrD)5 and GTrD9 as essential genes for the process of male gamete transmission in rice.

Decoding plant defense signaling using the defenseless mutant

New Phytologist, Volume 250, Issue 2, Page 1141-1156, April 2026.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),

A PLETHORA3/7 transcription factor shapes cucumber shoot architecture

New Phytologist, Volume 250, Issue 1, Page 230-245, April 2026.
Summary PLETHORA transcription factors (PLTs) are master regulators of plant development. Loss of shoot meristematic PLTs leads to reduced phyllotactic regularity and robustness in Arabidopsis and increased inflorescence branching in tomato. Whether these factors have similar functions in other species is not known.

MITOGEN‐ACTIVATED PROTEIN KINASE9 fine‐tunes hypoxia signaling by phosphorylating ERF‐VII transcription factors in Arabidopsis

New Phytologist, Volume 250, Issue 2, Page 1023-1040, April 2026.
Summary In plants, hypoxia sensing is controlled by the stabilization of group VII ethylene response factors (ERF‐VIIs), which are post‐translationally activated by the mitogen‐activated protein kinases (MAPKs) MPK3 and MPK6. However, how plants fine‐tune the MPK3/MPK6‐mediated phosphorylation of ERF‐VIIs to maintain cellular homeostasis remains ...

Linking Superoxide Production and Scavenging in Plant Development

Plant, Cell &Environment, Volume 49, Issue 4, Page 2048-2068, April 2026.
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 ...

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

Advanced Science, Volume 13, Issue 14, 9 March 2026.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium
