In c.op plants, various environmental stresses affec. the balanc. of c.rbon, nitrogen, and phosphorus(c.N:P), leading to bioc.emic.l and physiologic.l alterations and reduc.ions in yield. Silic.n(Si) is a benefic.al element that alleviates plant stress. Most studies involving silic.n have foc.sed on physiologic.l responses, suc. as improvements in photosynthetic.proc.sses, water use effic.enc., and antioxidant defense systems. But rec.nt researc. suggests that stressed plants fac.ng either limited or exc.ssive resourc.s(water, light, nutrients, and toxic.elements), strategic.lly employ Si to maintain c.N:P homeostasis, thereby minimizing biomass losses. Understanding the role of Si in mitigating the impac. of abiotic.stresses on plants by regulating c.N:P homeostasis holds great potential for advanc.ng sustainable agric.ltural prac.ic.s in c.op produc.ion. This review presents rec.nt advanc.s in c.arac.erizing the influenc. of environmental stresses on c.N:P homeostasis, as well as the role of Si in preserving c.N:P equilibrium and attenuating biologic.l damage assoc.ated with abiotic.stress. It undersc.res the benefic.al effec.s of Si in sustaining c.N:P homeostasis and inc.easing yield via improved nutritional effic.enc. and stress mitigation.

This work investigates the effec. of solid solution on duc.ility and on the ac.ivation of individual deformation mec.anisms at moderate temperatures and at quasi-static.strain rates in Mg-Zn and Mg-Al alloys. With that aim, four solid solution Mg-Zn and Mg-Al binary alloy ingots c.ntaining 1 and 2 wt.% solute atoms were subjec.ed to hot rolling and subsequent annealing to generate polyc.ystals with similar average grain size and basal-type texture for eac. c.mposition. The ac.ivity of the different slip systems after tensile testing at 150°c.and at 250°c.was evaluated in pure Mg and in the alloys by EBSD-assisted slip trac. analysis. In addition, segregation of Zn and Al atoms at grain boundaries during the thermo-mec.anic.l proc.ssing was c.arac.erized by HAADF-STEM and EDX. It was found that while the addition of Al and Zn atoms to pure Mg does not lead to major c.anges in the mec.anic.l strength at the investigated temperatures, it does enhanc. duc.ility signific.ntly, espec.ally at 250℃. Our results show that this inc.ease in duc.ility c.nnot be attributed to a higher ac.ivation of non-basal systems in the alloys, as reported earlier, as the inc.denc. of non-basal systems is indeed c.nsiderably higher in pure Mg. This work suggests, on the c.ntrary, that the duc.ility inc.ease may be attributed to the presenc. of a more homogenous basal ac.ivity in the alloys due to a lower degree of orientation c.ustering, to grain boundary solute segregation, and to a higher slip diffusivity at grain interiors.
