The Mediterranean Basin, a hotspot for tomato production, is one of the most vulnerable areas to climate change, where rising temperatures and increasing soil and water salinization represent major threats to agricultural sustainability. Thus, to understand the molecular mechanisms behind plant responses to this stress combination, an RNA-Seq analysis was conducted on roots and shoots of tomato plants exposed to salt (100 mM NaCl) and/or heat (42°C, 4 h each day) stress for 21 days. The analysis identified over 8000 differentially expressed genes (DEGs) under combined stress conditions, with 1716 DEGs in roots and 2665 in shoots being exclusively modulated in response to this specific stress condition.

Wheat production is limited by the rapid expansion of salinized arable land worldwide. Identification of the molecular mechanisms that underlie the salt stress response is of great importance. Here, we uncovered the NAC-type transcription factor, TaVOZ1, as a positive regulator of wheat salt tolerance.

Litopenaeus vannamei exhibits strong salinity adaptation; however, its survival and growth are significantly reduced in freshwater environments. To investigate the response mechanisms of L. vannamei to freshwater conditions, gill tissues from shrimp cultured for 30 days in both freshwater and seawater environments were used as experimental material in this study.

Ultraviolet-B (UV-B) light, a natural component of sunlight, plays a crucial role in the regulation of plant growth and development. B-box (BBX) proteins are zinc-finger transcription factors essential for plant growth, development, and responses to abiotic stress. The role of BBX5 in UV-B stress responses has not been previously identified.

Rice, as a vital food crop, faces persistent challenges in breeding programs aimed at achieving stable high yield under environmental stresses due to intrinsic trade-off mechanisms. This study functionally characterizes NARROW AND LONGER GRAIN 14 (NLG14), which encodes a spermine synthase. Loss-of-function nlg14 mutants exhibit slender grains due to enhanced cell expansion and proliferation, alongside significantly improved grain quality-manifested as reduced chalkiness, lower amylose/protein content, higher gel consistency, and superior taste value.
