The study evaluated drought tolerance and yield stability of eleven Andean amaranth genotypes (A. caudatus and A. mantegazzianus) across four agroecological zones in Northwest Argentina under irrigated and drought‑stressed conditions. Using linear mixed models and AMMI analysis, significant genotype and genotype‑by‑environment effects were detected, identifying several breeding lines with high yield and stability as well as a highly stable but low‑yielding landrace. The results highlight both broad and specific adaptation among amaranth genotypes for drought‑prone environments.

The study used a yeast two-hybrid screen to identify 52 wheat proteins that interact with the inositol pyrophosphate kinase TaVIH2-3B, highlighting the fasciclin‑like arabinogalactan protein TaFLA7 as a key partner involved in cell‑wall functions. Pulldown assays and reporter fusion analyses confirmed the interaction and plasma‑membrane localization of TaFLA7, which is modulated by TaVIH2‑3B activity and shows drought‑responsive and grain‑development expression in wheat.

Double mutant hybrids in the miR394‑regulated genes ZmLCR1 and ZmLCR2, created in a W22/B73 maize background, display enhanced drought tolerance through increased epicuticular wax and reduced ROS production, while maintaining normal flowering and nutrition. Under field rainfed conditions the mutants achieve significantly higher yields (greater ear weight and kernel number) compared to wild‑type hybrids.

The study used RNA-Seq to examine transcriptional responses to dehydration in seedlings of the drought‑tolerant oak Quercus douglasii, comparing dry‑down and well‑watered treatments. Few genes were differentially expressed, but many drought‑responsive genes showed high constitutive expression, indicating that Q. douglasii relies on a combination of constitutive expression and limited plasticity to tolerate drought.

The study investigated the five Arabidopsis SCAMP proteins, focusing on SCAMP5, and identified conserved tyrosine and NPF motifs that mediate anterograde transport and endocytosis, respectively. SCAMPs were shown to dimerize at the plasma membrane and endosomes, interact with plasma‑membrane aquaporins, and their loss (triple and quintuple mutants) conferred mild developmental delay but increased drought tolerance, likely via altered PIP trafficking or stability.

The study used comparative proteomics to examine how the emerging 15ADON/3ANX chemotype of Fusarium graminearum affects protein expression in both wheat and the fungus. It identified a core wheat proteome altered by infection, chemotype‑specific wheat proteins, and fungal proteins linked to virulence and ergosterol biosynthesis, revealing distinct molecular responses influencing disease severity.

Foliar application of Trichoderma harzianum cell‑free culture filtrates (CF) increased fruit yield, root growth, and photosynthesis in a commercial tomato cultivar under prolonged water deficit in a Mediterranean greenhouse. Integrated physiological, metabolite, and transcriptomic analyses revealed that CF mitigated drought‑induced changes, suppressing about half of water‑stress responsive genes, thereby reducing the plant’s transcriptional sensitivity to water scarcity.

The study examined three fruit morphotypes of the desert shrub Haloxylon ammodendron, revealing distinct germination performances under salt and drought stress. Proteomic analysis identified 721 differentially expressed proteins, particularly between the YP and PP morphotypes, linking stress‑responsive protein abundance to rapid germination in YP and delayed germination in PP as contrasting adaptive strategies. The findings suggest that fruit polymorphism facilitates niche differentiation and informs germplasm selection for desert restoration.

The study tracked molecular changes in plastoglobules and thylakoids of Zea mays B73 during heat stress and recovery, revealing increased plastoglobule size, number, and adjacent lipid droplets over time. Proteomic and lipidomic analyses uncovered up‑regulation of specific plastoglobule proteins and alterations in triacylglycerol, plastoquinone derivatives, and phytol esters, suggesting roles in membrane remodeling and oxidative defense. These insights highlight plastoglobule‑associated pathways as potential targets for enhancing heat resilience in maize.

Field trials of Pongamia pinnata in two subtropical Queensland sites revealed rapid biomass accumulation (13–19 kg per tree over 3–4 years) and high carbon sequestration (2.9–4.0 t C ha⁻¹) even on nutrient‑poor soils. Growth variability correlated with the maternal seed source, highlighting the importance of elite genetic material, and seedlings displayed strong drought tolerance.
