In the present study, onion germplasm was analyzed for various biochemical parameters in response to inoculation Alternaria. porri for establishing role of antioxidant defense mechanism in onion for understanding their role in antioxidant-associated defense mechanism. The genotypes were categorized as resistant, moderately susceptible, susceptible and highly susceptible based on percent disease index (PDI). There were significant differences for all the parameters studied before and after inoculation. As compared to resistant genotypes, the susceptible and highly susceptible genotypes showed minimum total chlorophyll content at 3 weeks post-inoculation. The total phenol content in the leaf of resistant genotypes was high (246.4 mg GAE/100g FW) as compared to moderate susceptible (115.99 mg GAE/100g FW), susceptible (151.14 mg GAE/100g FW) and highly susceptible (146.60 mg GAE/100g FW) genotypes at 3 weeks post-inoculation (WPI). The antioxidant enzymes namely catalase, peroxidase and superoxide dismutase production increased upto 3 WPI. The activity of antioxidant enzymes (catalase, peroxidase and superoxide dismutase) was significantly high in resistant genotypes (9.80, 12.80 & 9.39 µmole/min/mg protein, respectively) as compared to moderately susceptible, susceptible and highly susceptible genotypes at 3 WPI. The study supports that antioxidant enzymes play a significant role in defense mechanism in conferring resistance against purple blotch and can be used as an effective bio-marker in resistance breeding against Alternaria porri .","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135562479","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}

There are 129 species of Rubiaceae divided into 54 genera, including 20 endemic species. Martinique, a mountainous island occupying a central position in the archipelago, is home to 89 species of the family divided into 41 genera, including 2 endemic species. More than twenty species are grown or used as decorations, but the diversity of Rubiaceae found naturally in natural vegetation is significant, in terms of the number of species, genera or physiognomic types. As part of a doctoral thesis carried out in Martinique between 2015 and 2020, our knowledge about the ecology of this family has been enriched. In total, 120 floristic inventories were carried out in various natural plant formations. These data have undergone multivariate statistical processing, in particular using EXCEL and XLSTAT software. In total, 27 Rubiaceae species divided into 18 genera were observed (trees, shrubs, herbs, vines and epiphytes). Although the diversity and abundance of Rubiaceae vary according to the bioclimatic and therefore altitudinal gradient of the island, they are nevertheless rarely part of the dominant species assemblages. Due to the new climatic constraints of the 21st century, the current chorology of these species will evolve","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135562813","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, residues management particularly in rice–wheat system is a tedious phenomenon due to narrow gap between harvesting and sowing of these two crops. Hence, microbial intervention is one of the key options that may use successfully for their management. Thus, cellulolytic fungi were isolated from the cattle dung collected from various locations for cellulose manufacturing. The cellulolytic property of fungal isolates was confirmed by plate screening assay based on yellow zone formation surrounding of fungal culture on Congo red agar medium plate owing to production of cellulase enzyme. The colony diameter, clear zone diameter and cellulolytic index showing in descending order of CRD3, CRD5, CRD6 and CRD10 isolates, but –glucosidase activity was greater in CRD3 and CRD5 while, the lowest was in CRD9. However, isolates CRD7, CRD8 and CRD10 exhibited greater biochemical and enzymatic activity than rest of the promising fungal isolates. Similarly, isolates CRD1 and CRD2 utilized most of carbon sources as carbon substrate, but CRD7, CRD8 and CRD10 could not utilized mannitol and cellulose as carbon substrate. Overall, isolate CRD10 showed as a promising isolate in respect of biochemical, carbon utilization pattern and enzymatic activity than rest of the promising isolates.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78212083","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}
