Central to these ramifications is the process of photosynthesis, pivotal for carbohydrate synthesis and essential for sustaining growth amidst normal or stressful environmental conditions. Exposure to heat stress (HS) negatively affects the photosynthetic potential, primarily due to the increased synthesis of reactive oxygen species, disrupting the optimal functionality of the photosynthetic apparatus. Melatonin (MLT) has emerged as a multifaceted signaling molecule exhibiting promising capabilities in mitigating the adverse effects of abiotic stress including HS on plants. While a substantial body of literature addresses the enhancement of plant resilience to various environmental stresses using MLT, the present review specifically focuses on the impact of MLT on photosynthesis during HS. It emphasizes MLT’s role in regulating chlorophyll synthesis and degradation, regulating stomatal movement, safeguarding photosynthetic proteins, and sustaining the photosynthetic process under HS. This could be achieved by various mechanisms including enhancing the transcription of photosystem genes, activating antioxidant defenses, promoting the xanthophyll cycle, and modulating enzymes involved in photosynthesis and carbohydrate metabolism. Consequently, this review aims to enhance our understanding of how MLT mediates the protection of the photosynthesis process under HS, offering insights for the development of heat-tolerant crops.","PeriodicalId":503542,"journal":{"name":"CABI Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it has been implemented for a few commodities, the minimum support price (MSP) system has not been all-encompassing nor has the implementation of market intervention measures yielded much respite. This study makes the case that a thoughtful combination of the private investments and market intervention schemes (MIS) along with existing regimes of MSP could provide greater results. A strategy like this might offer farmers greater all-encompassing assistance while guaranteeing reasonable prices and stable markets. This study has reviewed two key existing frameworks by examining their strengths and flaws. Based on this analysis, it is possible to move forward by incorporating the best aspects of MIS and MSP. In addition to addressing the long-standing issues Indian farmers confront, this strategy could result in a more egalitarian and sustainable agriculture industry.","PeriodicalId":503542,"journal":{"name":"CABI Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141103225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the challenge of studying ancient samples and their microbiome, some approaches applied to the contemporary human microbiome have been successfully applied to ancient samples. Most studies in ancient samples have focused on taxonomic profiling at the community level with metagenomic or high-throughput 16S rRNA gene amplicon sequencing data. However, other approaches have emerged in order to get deeper understanding of the ancient human microbiome. Therefore, the aim of this review is to discuss all the approaches and methodologies successfully applied to ancient samples and ancient microbiome as well as the information that can be generated using them, in order to understand the evolution of human microbiome interactions throughout history.","PeriodicalId":503542,"journal":{"name":"CABI Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140722718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is one of the primary problems with today’s food systems, along with decreased agricultural yield and food quality. Many people attribute the decline in output and the deterioration of food quality to a lack of technology and ignorance about modern technologies. As a result, scientists are working hard to find innovative solutions to these problems and create new food production methods to feed the world’s growing population. Increased agricultural yields and quality may be achieved in a variety of settings by employing genetically engineered techniques. Newer techniques and technologies involving genetic modification and recombinant (r) deoxyribonucleic acid could be very helpful in the pursuit of significant improvements in food production and food supply, and biotechnology is a key part of this. Recent progress in genetic engineering, where it came from, the current trend, and its potential future are all discussed in this overview. Genetically modified organisms (GMOs) are major aspects of the industrial food system, and most packaged foods contain GMOs ingredients that have been bred to be resistant to pesticides and herbicides. There are a number of factors that raise red flags concerning GMOs, including safety, consequences on the environment and present ineffective employment of pesticides have also been considered. Furthermore, GMOs regulation and controversy among different scientists has also been discussed. Many individuals are concerned about GMOs, yet they may not fully grasp the concerns at hand. Therefore, the level of GMO knowledge revealed by this review can be calculated.","PeriodicalId":503542,"journal":{"name":"CABI Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140721416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An integrated strategy-combination approach incorporating nutrition and manure management is necessary to dramatically reduce GHGs and the carbon footprint of milk production. The aim of this review was to assess the effect of climate action mitigation strategies on the GHG production of ruminant animals. This review was based on the different references, which are textbooks, journals, proceedings, conferences, and abstracts accessed through Agricola, Agris, CAB Abstracts, Embase, MEDLINE, and the Web of Science. The research findings were done by using dairy cattle, sheep, and goat; the numbers of animals used in each experiment were given the majority of attention, and decisions were also made based on the method used to quantify methane (CH\u0000 4\u0000 ) and nitrous oxide. Enteric CH\u0000 4\u0000 per unit of milk was reduced by 6–8% when higher-starch corn silage was used in place of barley or alfalfa silage. Cows fed seaweed (1.77–2%, on dry matter [DM] basis) experienced a linear drop in enteric CH\u0000 4\u0000 emission from 383 to 400 g/d. Supplementation of vegetable fats (6%) and coconut oil (12 g/day) to ruminant diets can decrease CH\u0000 4\u0000 emissions by 21–40% and 50–61.2%, respectively. Similarly, the addition of 21.5 g nitrate/kg DM reduces CH\u0000 4\u0000 yield (17%) in sheep. Bovaer can reduce methane emissions (30%) for dairy cows. Feed processing and additives are alternative strategies to minimize GHG production in ruminants, but further studies on additives and their residual effect on livestock output is needed.\u0000","PeriodicalId":503542,"journal":{"name":"CABI Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140721348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
