Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

Journal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Field generation of triparental sugar beet plants through polyspermy‐induced three‐parent breeding

New Phytologist, EarlyView.
Polyspermy, the fertilization of an egg by two sperm cells, can generate viable triparental offspring in the model plant Arabidopsis thaliana. To explore the potential for three‐parent breeding in a crop species, male‐sterile sugar beet plants were grown alongside genetically distinct pollen donors carrying dominant, traceable selection markers ...

Differential effect of nano vs. micro-sized plastics on live Chlorella sp. algae in water environment

Microplastics and Nanoplastics
Environmental pollution by micro and nanoplastics (MPs) is becoming an imminent danger for the environment in the 21st century. However, the effect of the MPs of different sizes is still poorly understood.

Embryonal degreening and seed longevity require plastid LEA proteins

New Phytologist, EarlyView.
Working model of how plastidial LEA proteins aid the remodelling of photosynthetic structures during degreening of Arabidopsis seed embryos. LEA42 and LEA48 support thylakoid proteostasis and membrane remodelling in embryonal cells during late seed maturation by maintaining a local physicochemical environment compatible with protein turnover and ...

A Heat‐Inducible Rubisco Activase Safeguards Photosynthesis via Multilevel Regulation and Dual Function

Plant Biotechnology Journal, EarlyView.
ABSTRACT Rubisco activase (RCA) is critical for maintaining photosynthetic efficiency under heat stress, yet its regulatory mechanisms and functional diversification remain poorly understood. Here, we characterize a novel heat‐inducible RCA family member (RCA1), which plays a pivotal role in mediating multidimensional thermotolerance in a tropical ...

LMS-Net: A Light-Weight Network for Mungbean Salt Stress Identification

IEEE Access
Salt stress is one of the main factors affecting mungbean production, and the assessment of salt tolerance in mungbean typically requires long-term morphological observation or time-consuming physiological and biochemical experiments, which are time ...
