Published: Jan. 10, 2021

The potential impacts of climate change on current livestock systems worldwide are a major concern, and yet the topic is covered to limited extent in global reports such as ones produced by Intergovernmental Panel Climate Change. In this article, we review risk climate-related along land-based food supply chain. Although quantification net sector beyond reach our understanding, there strong evidence that will be throughout chain, from farm production processing operations, storage, transport, retailing human consumption. risks highly context-specific but expected higher environments already hot have socio-economic institutional resources for adaptation. Large uncertainties remain futures exposure responses interlinked natural climatic changes over time. Consequently, adaptation choices need account wide range possible futures, including those with low probability large consequences.

Halotolerant biofilm-producing rhizobacteria mitigate seawater-induced salt stress and promote growth of tomato

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: April 4, 2022

Biofilm-producing rhizobacteria (BPR) enhance productivity and mitigate abiotic stresses in plants. This study showed that 21 out of 65 halotolerant could build biofilms. The components the biofilm matrices i.e., extracellular polymeric substances (EPS) are proteins, curli, nanocelloluse, nucleic acids, lipids, peptidoglycans. Various functional groups including carbonyl, carboxyl, amino, hydroxyl, phosphate were identified. Positions these shifted by application 5% NaCl, suggesting Na+ biosorption. By sequencing, Glutamicibacter arilaitensis (ESK1, ESM4 ESM7), G. nicotianae (ESK19, ESM8 ESM16), Enterobacter ludwigii (ESK15, ESK17, ESM2 ESM17), E. cloacae (ESM5 ESM12), Exiguobacterium acetylicum (ESM24 ESM25), Staphylococcus saprophyticus ESK6, Leclercia adecarboxylata ESK12, Pseudomonas poae ESK16, Bacillus subtilis ESM14, P. putida ESM17 These exhibited numerous plant growth-promoting (PGP) activities producing IAA, ACC deaminase, siderophores, solubilizing phosphate. Under non-stress, bacterized plants increased biomass accumulation (8-23.2% roots 23-49.4% shoots), while under seawater-induced salt stress only ESM4, ESM12, ESM14 enhanced production (5.8-52.9% 8.8-33.4% shoots). Bacterized induced antioxidant defense system (19.5-142% catalase 12.3-24.2% DPPH radical scavenging activity), retained a greater relative water content (17-124%), lesser membrane injuries (19.9-26.5%), reduced (6-24% roots) K+/Na+ ratio (78.8 103% ESK12 ESM24, respectively) than non-bacterized saline conditions. Thus, native BPR can be utilized as ameliorators stress.

Arbuscular Mycorrhizal Fungi Enhance Biomass Growth, Mineral Content, and Antioxidant Activity in Tomato Plants under Drought Stress

Journal of Food Quality, Journal Year: 2023, Volume and Issue: 2023, P. 1 - 14

Published: March 7, 2023

Arbuscular mycorrhizal fungi (AMF) are symbiotically associated with crops. They increase biomass production, nutritional elements, and antioxidant activities in food vegetable crops grown soil under stress conditions. The present study focused on the effects of AMF (Acaulospora morrowiae, Paraglomus occultum, Funneliformis mosseae, Rhizophagus clarus, intraradices) growth yield, contents chlorophyll carotenoids, catalase (CAT) ascorbate peroxidase (APX), hydrogen peroxide (H2O2), malondialdehyde (MDA), minerals (Na, K, Ca, Mg, Fe) Unnayan, LT896, Minto super tomato (Solanum lycopersicum L.) varieties drought (<10% moisture). results showed that root length shoot mass plants treated R. clarus P. occultum were significantly higher than those control (non-AMF) tomato. Compared to control, shoot’s dry weight yield enhanced by 28% 20% AMF-treated tomatoes. CAT activity occultum-treated was statistically Unnayan H2O2 content detected clarus-treated LT896 In A. morrowiae APX increased 42% 66% leaves tomatoes compared non-AMF. Treatment reduced MDA (ROS) 50% 2% respectively. Potassium (K), calcium (Ca), magnesium (Mg), iron (Fe) fruits 2%, 13%, 24%, 37% treatment control.

China’s shrimp farming industry has experienced significant growth in recent years. With such a development, some major constraints linked to the industry’s sustainable development have emerged. This paper aims present an overview of over last two decades, with special attention farm-raised both marine and inland waters. Documentary research on its evolution was carried out based data collected from China Fishery Statistics Yearbooks 2003 2022 coupled FAO. Findings indicated that there been upward trend total production 20 years, rate 120%, representing average annual 4.3%. The observed higher driven by expanded aquaculture production, species dominated Pacific whiteleg ( litopenaeus vannamei ), black tiger Penaeus monodon Chinese chinensis Japanese prawn japonicus ). Challenges associated intensification environmental deterioration need be properly addressed. First, should practiced while considering environment ecosystem protection. Applying organic principle presupposes practices for addressing existing issues threatening industry. To end, is innovative techniques strengthened. Second, possible solutions disease problems, namely prevention, early diagnosis, various control techniques, also developed improved, emphasis former. In addition, encouraging use good-quality feed appropriate quantity form paramount importance. It thus worth noting further policies focus promoting large range ecological technologies encouraged among farmers.

Agriculture, Journal Year: 2019, Volume and Issue: 9(10), P. 223 - 223

Published: Oct. 13, 2019

Attempts to cultivate sugar beet (Beta vulgaris spp. vulgaris) in the sub-tropical saline soils are ongoing because of its excellent tolerance salinity. However, intrinsic adaptive physiology has not been discovered yet climatic conditions. In this study, we investigated morpho-physiological attributes, biochemical responses, and yield under a gradient salinity soil–pot culture system evaluate mechanisms. Results exhibited that low high displayed differential impact on growth, photosynthesis, yield. Low moderate salt stress (75 100 mM NaCl) showed no inhibition growth photosynthetic attributes. Accordingly, simulative effect chlorophyll antioxidant enzymes activity which contributed maintaining balanced H2O2 accumulation lipid peroxidation. Furthermore, relative water proline content alteration These factors improving (tuber weight). On contrary, 250 mostly inhibitory role Collectively, our findings provide insights into mild–moderate adaptation strategy soil test attributed increased content, elevation pigment, better management oxidative stress. Therefore, cultivation moderately saline-affected will ensure efficient utilization lands.
