The Global Wheat Dataset Consortium released a comprehensive semantic segmentation dataset (GWFSS) of wheat organs across developmental stages, comprising 1,096 fully annotated images and 52,078 unannotated images from 11 institutions. Models based on DeepLabV3Plus and Segformer were trained, with Segformer achieving ≈90% mIoU for leaves and spikes but lower precision (54%) for stems, while also enabling weed exclusion and discrimination of necrotic, senescent, and residue tissues.

The study reveals that root hair-forming trichoblast cells in Arabidopsis thaliana display higher autophagic flux than adjacent atrichoblast cells, a difference linked to cell fate determination. Elevated autophagy in trichoblasts is required for vacuolar sodium sequestration, contributing to salt‑stress tolerance, whereas disrupting autophagy in these cells impairs ion accumulation and survival. Cell‑type‑specific genetic complementation restores both autophagy and stress resilience, highlighting a developmental program that tailors autophagy for environmental adaptation.

The study reveals that the bacterial pathogen Pseudomonas syringae suppresses host plant translation by targeting processing bodies (P‑bodies) through two liquid-like effectors, linking this repression to the ER stress response. It further demonstrates that autophagic clearance of P‑bodies is essential for balancing translationally active and inactive mRNAs, uncovering new connections among translation, ER stress, and autophagy during plant immunity.

The study investigated melatonin priming on methylglyoxal detoxification and autophagy during PEG‑induced drought stress in seed germination of drought‑sensitive (L‑799) and tolerant (Suraj) upland cotton. Melatonin increased endogenous melatonin, reduced MGO and AGEs, up‑regulated glyoxalase enzymes and autophagy markers, and improved cell viability in the sensitive variety, while the tolerant variety showed limited response.

RNA‑seq of 328 wheat lines using a pan‑genome reference uncovered over 20,000 additional transcripts beyond the Chinese Spring genome and enabled construction of a pan‑gene eQTL regulatory atlas. Multi‑omics integration identified 231 high‑confidence candidate genes influencing 34 agronomic traits and powdery mildew resistance, with functional validation showing 80% of candidates affecting trait phenotypes via an EMS mutant library.

This review compiles experimental studies on wheat to assess how elevated CO₂, higher temperatures, and water deficit interact and affect productivity and water use. By calculating plasticity indices, the authors find that despite CO₂‑induced gains, overall yield generally declines under combined stress, while water consumption often decreases. They highlight the need for more data to improve and validate crop models under future climate scenarios.

The study introduces Transposase-Accessible Chromosome Conformation Capture (TAC-C), which combines ATAC‑seq and Hi‑C to map fine‑scale chromatin interactions in rice, sorghum, maize, and wheat, revealing genome‑size‑correlated loop structures and distinct C3 vs. C4 patterns. Integration with population genetics shows that loops link distal regulatory elements to phenotypic variation, and SPL transcription factors (TaSPL7/15) modulate photosynthesis‑related genes via these interactions, enhancing photosynthetic efficiency and starch content in wheat mutants.

The study demonstrates that loss of Arabidopsis metacaspase 1 (AtMC1) triggers autoimmunity reliant on downstream NLR and PRR signaling, and that overexpressing a catalytically dead AtMC1 exacerbates this effect. Overexpression of the E3 ligase SNIPER1 restores normal immunity, suggesting that AtMC1 regulates NLR protein turnover, possibly via autophagic degradation of the inactive protein.
