We recently reported the cloning and characterization of an Arabidopsis (ecotype Columbia) diacylglycerol acyltransferase cDNA (Zou et al., 1999) found that in mutant line AS11, ethyl methanesulfonate-induced mutation at a locus on chromosome II designated as Tag1 consists 147-bp insertion DNA, which results repeat 81-bp exon 2 cDNA. This is correlated with altered seed fatty acid composition, reduced (DGAT; EC 2.3.1.20) activity, triacylglycerol content, delayed development AS11 mutant. The...
Increasing the consumption of natural substances has increased demand for biological sources such as Spirulina platensis. The study quantitatively investigates antioxidant potential and phytonutrient contents in aqueous ethanol extracts spirulina. spirulina was collected from a local farm Pondicherry mass cultured our research laboratory. biomass evaluated viz. catalase, SOD, GPx, Vitamin C, E, reduced GSH; phytonutrients like total phenol, flavonoid, tannin, carbohydrates, proteins both...
Summary In Arabidopsis thaliana (ecotype Columbia) mutant line AS11, an EMS‐induced mutation at a locus on chromosome II results in reduced diacylglycerol acyltransferase (DGAT; EC 2.3.1.20) activity, seed triacylglycerol, altered fatty acid composition, and delayed development. A has been identified AS11 gene, which we designated as TAG1 , that encodes protein with amino sequence is similar to recently reported mammalian DGAT, and, lesser extent, acyl CoA:cholesterol acyltransferases....
Top–down control analysis (TDCA) is a useful tool for quantifying constraints on metabolic pathways that might be overcome by biotechnological approaches. Previous studies lipid accumulation in oilseed rape have suggested diacylglycerol acyltransferase (DGAT), which catalyses the final step seed oil biosynthesis, an effective target enhancing content. Here, increased content, DGAT activity, and reduced substrate:product ratio are demonstrated, as well flux complex assembly, determined TDCA...
In the era of climate change, decreased precipitation and increased evapo-transpiration hampers yield several cereal crops along with soil salinity poor ground water resource. Wheat being moderately tolerant crop face many challenges in arid semi-arid regions under irrigated agriculture. view this, study was planned to explore potential durum wheat genotypes on basis physiological traits. Experiment designed as RBD three replications evaluate 15 moderate saline irrigation (ECiw – 6 dS m−1)...
Salinity stress is a major constraint to sustainable crop production due its adverse impact on growth, physiology, and productivity. As potato the fourth most important staple food crop, enhancing productivity necessary ensure security for ever-increasing population. Identification cultivation of salt-tolerant genotypes are imperative mitigating strategies cope with conditions. For this purpose, fifty-three varieties were screened under control salt conditions growth yield-related traits...
Spontaneous mutation and natural selection pressure have contributed immensely to the genetic diversity of barley; a crop domesticated grown since antiquity under diverse agro-ecological regions. Similarly, anthropogenic factors like cultural traditions food preferences also shaped evolution barley in course acclimatization ecosystems. Despite rich diversity, rapid depletion resources including virtual extinction several important landraces due introduction high yielding varieties loss...
Salt stress induced modulations in different ionic ratios and ROS system were studied ten halophytic species, namely Atriplex lentiformis, Tamarix aphylla, Sporobolus marginatus, Suaeda nudiflora, Urochondra setulosa, Arundo donax, Aeluropus lagopoides, Heliotropium ramossimum, nummularia, Leptachloa fusca at salinity level of ECe ∼ 30 dSm−1 (≈300 mM NaCl) to explore their possible role salt tolerance ability these halophytes. These halophytes categorized for levels based on the Na+/K+,...
Abstract India is facing economic losses of $US ~ 3.0 billion annually due to the existence 6.73 million ha un‐reclaimed salt‐affected soils (SASs). The may go up significantly as future projections indicate an increase in area SASs extent ~16 by 2050, impact faulty irrigation practices and climate change. Managing one major challenges achieving land degradation neutrality, increasing crop productivity, sustaining food security India. Although problem has been reduced some through various...
Grafting on salt tolerant eggplant rootstocks can be a promising approach for enhancing the salinity tolerance of tomato. In this study, performance tomato cv. Kashi Aman grafted two (IC-111056 and IC-354557) was evaluated against non-grafted control under saline (ECiw 6 9 dS m−1) non-saline ~1 irrigation 2 years. improved plant stress. Moreover, rootstock IC-111056 outperformed IC-354557. An increase in average fruit yield plants compared with at m−1 24.41% 55.84%, respectively 20.25%...
Pearl millet is a staple food for more than 90 million people residing in highly vulnerable hot arid and semi-arid regions of Africa Asia. These are prone to detrimental effects soil salinity on crop performance terms reduced biomass yields. We investigated the physiological mechanisms salt tolerance irrigation induced stress (ECiw ~3, 6 & 9 dSm-1) their confounding plant growth yield pearl inbred lines hybrids. On average, nearly 30% reduction above ground was observed at ECiw ~6 dSm-1...
Aeluropus lagopoides (grass halophyte) and Suaeda nudiflora (non-grass collected from extreme saline sodic Kachchh plains, Bhuj (Gujrat), were established in micro-plot research facility of CSSRI, Karnal, to evaluate their eco-physiological responses under different salt stresses. The experiment was designed split plot design (two factorial randomized complete block design) having 2 halophytes 9 treatments salinity/sodicity, i.e., control (pH2 7.1; ECe: 0.56), 9.5 10.0), (ECe: 15, 25, 35 dS...
The development of salinity affects 7% the world’s land surface, acting as a major constraint to crop productivity. This study attempted use co-evolving endophytes peanut alleviate stress and enhance yield peanut. Diverse different tissue colonizing were isolated from screened in vitro by seed germination bioassay imposing gradients salinity, with two cultivars TG37A (susceptible) GG2 (moderately resistant), potted conditions using saline irrigation water. Finally, nine capable producing IAA...
Arabidopsis thaliana was transformed with a plastidial safflower glycerol-3-phosphate acyltransferase (GPAT) and an Escherichia coli GPAT. The genes were used directly in modified forms with, as applicable, the targeting sequence removed, endoplasmic reticulum added. Seeds of plants using only vector indistinguishable oil content from wild-type control plants. All other gene constructs increased seed content. unmodified (spgpat) produced increases ranging 10 to 21%. On average, greatest...
Tillage is an important agricultural operation which influences soil properties, crop yield and environment. Nine combinations of three tillage practices including conventional (CT), minimum (MT) zero (ZT) were evaluated in fodder sorghum (Sorghum bicolor) + cowpea (Vigna unguiculata) – wheat (Triticum durum) cropping system for 5 years (2009–2014) on clay loam under limited irrigation. Continuous ZT significantly improved surface organic carbon, bulk density, infiltration rate maximum water...
