Article Abstract
Salt is an important environmental stress factor, which seriously affects the growth, development and distribution of plants. Chlorophyllase plays an important role in stress response. Nevertheless, little is known about the physiological and molecular mechanism of chlorophyll (Chlase, ) genes in plants. We cloned from and found that was differentially expressed in different tissues, especially in the leaves of . To further study the role of in salt tolerance, overexpression and RNA interference transgenic lines were established in × and used for salt stress treatment and physiologic indexes studies. Overexpressing lines significantly improved tolerance to salt treatment and reduced reactive oxygen species production. RNA interference lines showed the opposite. Transcriptome analysis was performed on leaves of control and transgenic lines under normal growth conditions and salt stress to predict genes regulated during salt stress. This provides a basis for elucidating the molecular regulation mechanism of in response to salt stress and improving the tolerance of poplar under salt stress.

Background: Sweet orange is an important economic crop, and salt stress can inhibit its growth and development.
Methods: In this study, we identified AP2/ERF genes in sweet orange via bioinformatics and performed a combined transcription‒metabolism analysis, which revealed for the first time the integrated molecular mechanism of salt stress regulation in sweet orange.
Key Results: A total of 131 sweet orange AP2/ERF genes were identified and categorized into five groups.

Bacteria experience a continual array of environmental stresses, necessitating adaptive mechanisms crucial for their survival. Thermophilic bacteria, such as Thermus thermophilus, face constant environmental challenges, particularly high temperatures, which requires robust adaptive mechanisms for survival. Studying these extremophiles provides valuable insights into the intricate molecular and physiological processes used by extremophiles to adapt and survive in harsh environments.

Improving crop salinity management requires enhanced understanding of salinity responses of leaf and fine-root traits governing resource acquisition, ideally in relation to ion accumulation at intra- or inter-specific levels. We hypothesized that these responses are coupled towards integrated resource conservation for plants under prolonged salt treatment. We tested the hypothesis with a glasshouse experiment on saplings of six contrasting hybrids, subjected to either control or salt treatment (reverse osmosis water versus 3.

The current study aimed to assess the preventive effects of aqueous leaf extract of Pistacia lentiscus (ALEPL) against Oxaliplatin (OXA)-induced DNA damage, hepatic injury, and oxidative stress. The in vitro cytotoxic and genotoxic effects of OXA and ALEPL on HCT116 colon cancer cells were evaluated using the MTT (Tetrazolium salt reduction) assay and comet assay. The in vivo study involved 24 female NMRI (Naval Medical Research Institute) mice that were equally divided into four groups as follows: Control group, ALEPL-treated group (100 mg/kg), OXA-treated group (7 mg/kg), and ALEPL-treated group (100mg/kg) + OXA (7mg/kg).

Sorghum is an increasingly popular topic of research in elucidating survival and adaptation approaches to augmented salinity. Nonetheless, little is known about the outcome and modulatory networks involved in the gibberellic acid (GA3)-induced salt stress alleviation in sorghum. Here, we identified 50 mg/L GA3 as the optimal concentration for sorghum ('Jitian 3') development under salt stress.
