We review the status of the hypothesis that interventions that increase the resistance to stress offer the potential for effective life prolongation and increased health. The work focuses on research in the nematode worm Caenorhabditis elegans and describes both published and unpublished results consistent with this hypothesis. Correlation between stress resistance and longevity among many gerontogene mutants is provided.

Tomato (Solanum lycopersicum) is an important crop but frequently experiences saline-alkali stress. Our previous studies have shown that exogenous spermidine (Spd) could significantly enhance the saline-alkali resistance of tomato seedlings, in which a high concentration of Spd and jasmonic acid (JA) exerted important roles. However, the mechanism of Spd and JA accumulation remains unclear.

DREB1A, a pivotal transcription factor, has long been known to regulate plant abiotic stress tolerance. However, its role in plant biotic stress tolerance and the underlying mechanisms have remained a mystery. Our research reveals that the maize ZmDREB1A gene is up-regulated in maize seedlings when the plants are infected by Rhizoctonia solani (R.

Background: Glyphosate is an extensively employed herbicide in agriculture, specifically for sugarcane cultivation. The situation is different with the extensive physiological and genetic effects exerted by this herbicide on a range of plant species, including sugarcane, whose model basis is still poorly characterized, although its primary mode of action, which acts on the EPSPS enzyme in the shikimic acid pathway, is completely elucidated. The current study was aimed at investigating the stability of glyphosate formulation, molecular interactions of glyphosate formulation with rbcL enzyme associated with chlorophyll metabolism, and its effects on varieties of sugarcane.

A complex regulatory network governs fruit ripening, but natural variations and functional differentiation of fruit ripening genes remain largely unknown. Utilizing a genome-wide association study (GWAS), we identified the NAC family transcription factor MdNAC18.1, whose expression is closely associated with fruit ripening in apple (Malus × domestica Borkh.

The contribution of sex hormones to cardiovascular disease, including arterial stiffness, is established; however, the role of sex chromosome interaction with sex hormones, particularly in women, is lagging. Arterial structural stiffness depends on the intrinsic properties and transmural wall geometry that comprise a network of cells and extracellular matrix (ECM) proteins expressed in a sex-dependent manner. In this study, we used four-core genotype (FCG) mice to determine the relative contribution of sex hormones versus sex chromosomes or their interaction with arterial structural stiffness.
