These are very important part of sustainable agriculture and also for diverse industrial or other uses. But their production has compromised due to lack of interest among farmers and presence of constraints, rendering it appropriate to use as a food crop. Improvement has lagged in Sesbania species because of the unavailability of the gene pool, along with self-incompatibility in closely related species. Lacunae in improvement of its species could overcome with the help of biotechnological tools that could transfer genes in distantly related species, too. Mostly, an efficient and reproducible regeneration system is a prerequisite for efficient transgenic plant production. However, progress has made towards in vitro regeneration in various Sesbania species such as S. bispinosa, S. grandiflora, S. sesban using hypocotyl explants and using cotyledonary node explants in S. drumondii and S. rostrata. Considerable success has also been obtained in plant regeneration via somatic embryos in S. sesban and via protoplasts in S. bispinosa. But, till date only in S. drumondii one report on generation of transgenic plants is available, where T0 plants have been obtained using cotyledonary node explants. In this regard, the current paper highlights the in vitro regeneration and genetic transformation protocols developed so far in Sesbania species along with future directives towards improvement of this important genus.","PeriodicalId":37168,"journal":{"name":"Reviews in Agricultural Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71254003","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}

However, the long-term and indiscriminate use of these chemicals has a negative impact on environment and human health; thus, public concerns about the hazardous effects of such synthetic chemicals are increasing day by day. To solve these problems, the exploitation of potential alternatives has become a major challenge, and the admiration of beneficial microbes is increasing due to their safe and environment-friendly nature. Microbes can mitigate the hazardous effects of synthetic chemicals by reducing their use and toxicity. Lysinibacillus species are gram-positive, spore-forming, motile bacteria. This genus was previously designated as Bacillus spp. under the family Bacillaceae of the phylum Firmicutes. For a long period of time, Lysinibacillus is well-known for its insecticidal activity against various insects, including mosquitoes, which are the vector of several human diseases. In addition, some Lysinibacillus species have a potential for heavy metal remediation. In recent years, Lysinibacillus spp. are attracting the researchers’ attention as plant growth-promoting and disease control agents, which would be used as alternatives to agrochemicals. This study gives an overview of the entomopathogenic, bioremediation, plant growth-promoting, and biological disease control abilities of the genus Lysinibacillus.","PeriodicalId":37168,"journal":{"name":"Reviews in Agricultural Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71254063","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}

Globalization that takes place through changes in the political system has most impacts on the diversity of livelihoods of rural communities. However, there are few studies of diversity in the field, and most focus on sectoral shifts and financial activities. We conducted an overview of the historical dynamics of rural livelihoods and its diversification, and used various indices to measure diversification. To reveal the complex diversity of rural livelihoods it is necessary to understand the general situation and patterns of livelihood diversification. This article highlights the diverse livelihood dynamics from two viewpoints of livelihood diversification; distress and progressive diversification, and case studies that can support these dynamics to illustrate the process of livelihood diversification and discuss the direction of the pattern of diversification to provide information for future research. This study suggested intensified focus on livelihood diversification to promote sustainable development in this region.","PeriodicalId":37168,"journal":{"name":"Reviews in Agricultural Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71253982","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}

Kato","doi":"10.7831/RAS.9.0_20","DOIUrl":"https://doi.org/10.7831/RAS.9.0_20","url":null,"abstract":"Citrus ‘Harumi’ is a mandarin-type cultivar and shows a wide range of fruit size, which affects fruit quality such as sugar and acid contents. In citrus, fruit size also affects the degree of physiological disorder which become a big problem during storage. Thus, making fruit with equal and appropriate size is very important. Fruit thinning is one of the most important techniques to adjust fruit size by controlling the fruit number. Basically, fruit thinning has been conducted using a criterion based on leaf and fruit ratio (L/F) or fruit number per canopy volume. In this review, several thinning criteria for ‘Harumi’ and other citrus varieties are compared, and the pros and cons are discussed. In some citrus varieties, storage is necessary to adjust shipping time. During the storage, some physiological disorders occurred in peel, flesh and whole fruit. The occurrence of physiological disorders was influenced by citrus variety, fruit size and environmental conditions during storage. In ‘Harumi’ which is classified to easy-peeling variety, small fruit showed serious weight loss and peel wrinkle, while rind puffing and dehydration of flesh were big problems in large fruit during storage. Polyethylene (PE) bag wrapping has been used to decrease the fruit weight loss and to prevent the occurrence of some physiological disorders in tightskin citrus varieties. However, the influences of PE wrapping on easy-peeling citrus is unclear. In this study, the researches on storage conditions, feature, and cause of physiological disorders during storage are also reviewed, and the effects of PE wrapping are discussed to improve storage condition in ‘Harumi’.","PeriodicalId":37168,"journal":{"name":"Reviews in Agricultural Science","volume":"56 64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71254513","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}

Yamamoto","doi":"10.7831/RAS.9.0_117","DOIUrl":"https://doi.org/10.7831/RAS.9.0_117","url":null,"abstract":"Metabolism, which is a flow of metabolites, is orchestrated by gene expression, and it is in turn regulated by metabolites. Some of the metabolites are known to act as signaling molecules that regulate metabolism and also developmental processes in plants. Here we summarize findings about metabolites-directed gene regulation, focusing on primary metabolites including sugars and organic acids. Abundant soluble sugars such as sucrose and glucose are known to induce genes involved in starch storage, synthesis and degradation. These sugars also activate anthocyanin biosynthesis and suppress photosynthetic genes, both of which promote photoprotection responses. Several kinases, like hexokinase, sucrose non-fermenting1-related kinase 1 and target of rapamycin kinase have been identified, which are the major regulators of transcriptional regulation by these sugars. Although less studied than sugars, metabolites constituting the TCA cycle are good candidates of signaling molecules, because they are located in the primary metabolism adjacent to the respiratory electron transport system and thus are reflected by both primary metabolism and redox status of the electron transport system. Some organic acids as citrate, malate and 2-oxoglutarate have also been known to be implicated in the regulation of gene expression. Deficiency or over accumulation of some primary metabolites not only modulate gene expression of the local metabolic enzymes to supplement distorted metabolism but produce signals to balance between bigger metabolic blocks like carbon and nitrogen metabolisms. Status of primary metabolites can also produce signals of overall energy levels of plants. Relationship of sugar signaling to reactive oxygen species signaling is also suggested.","PeriodicalId":37168,"journal":{"name":"Reviews in Agricultural Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71253921","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}
