To investigate the temporal sequence of physiological reactions of peanut seedlings (Arachis hypogaea L.) to cadmium exposure, seeds were cultured in increasing concentrations of CdCl(2), ranging from 50 to 300 mu M. Germination frequency was scored, and the distributions of Cd in root, stem, and leaves were determined after 2 and 4 weeks of culture. Lipid peroxidation and activities of antioxidative enzymes including catalase (CAT, EC 1.11.1.6) and guaiacol peroxiclase (GPX; EC 1.11.1.7) were estimated in these three parts of the plant. Germination of seedlings was not affected, but the growth of seedlings was severely suppressed with increasing concentrations of CdCl(2) and incubation period. Pattern of Cd distribution in the three organs varied with concentration and period of exposure to Cd. Increased lipid peroxidation was detected in all parts of the developing seedlings with increasing metal accumulation. Catalase and guaiacol peroxidase activity varied in the three parts of the seedlings with concentration of Cd and incubation period. Guaiacol peroxidase activity appears to be more active in scavenging the reactive oxygen species in developing peanut seedlings. The results of the present experiment demonstrate the advantages of a tissue-culture model system in studying the complex network of interactions of various factors in stress tolerance.</p>10aAbiotic stress10aheavy metal10astress tolerance10aTBARS10athiobarbituric acid10aTissue culture1 aKumar, Sunil1 aMehta, Urmil, J.1 aHazra, Sulekha  uhttps://library.ncl.res.in/content/accumulation-cadmium-growing-peanut-arachis-hypogaea-l-seedlings-its-effect-lipid-002888nas a2200253   4500008004100000022001400041245011400055210006900169260000800238300001400246490000700260520204600267653001602313653002002329653001902349653003102368653000802399653001602407653002202423653002102445100002202466700001702488856012902505       2024                        eng d  a0006-308800a Positive role of polyunsaturated fatty acids on sustainable crop production against salt stress: an overview0 aPositive role of polyunsaturated fatty acids on sustainable crop  cJUN  a1599-16100 v793 a<p>
	Abiotic stresses have become more severe and capricious due to global warming and varying climatic conditions, with increased temperature reducing the yield of important agricultural crops due to high evapotranspiration, resulting in the increased amount of soil salinization in arid and semi-arid areas, which has become a significant threat that restricts agricultural practices and leads to the overexploitation of cultivation land. One of the crucial environmental elements limiting plant development and yield is salinity. The special effects of salt stress on the superiority of numerous crops have yet to be discovered. Under salinity, plants tend to activate multiple physiological and biochemical mechanisms to overcome the stress by altering their morphology, photosynthesis, water relations, and biochemical adaptations, such as the antioxidative metabolism response and trigger polyunsaturated fatty acids (PUFAs), which act as a biomarker for salinity stress. With the help of PUFAs, which have become popular as all-purpose defenders, decorative techniques have been created to prevent the consequences of saline. The most prevalent PUFAs in plants are those with 18 carbons, specifically 18:1 (oleic), 18:2 (linoleic), and 18:3 (alpha-linolenic) acids which operate as glycerolipids, a source of energy and carbon in triacylglycerol, precursors of numerous bioactive chemicals, stores of extracellular barrier components, and intrinsic antioxidants, modulating cellular membranes and enhancing crop quality and yield. However, limited information about PUFAs and their roles in enhancing crop stress tolerance is available. Therefore, producers and breeders must understand salinity's influence on crop composition to enhance fatty acids under salinity conditions. However, brief work has been reported; this review will help comprehend the role of fatty acids in salinity for food security through the genetic engineering of synthetic genes encoding fatty acids to improve crop stress tolerance and grain quality.</p>
