Conidial morphology showed that most of the isolates in the study belonged to A. macrospora. Molecular confirmation is necessary to strengthen the identification of species in Alternaria. Genetic diversity study of Alternaria isolates using ISSR and hyper variable SSR primers will provide variation and grouping among the isolates collected from major areas of South Zone of India. Present study was conducted to identify Alternaria isolates at species level using molecular methods (species specific primers) and genetic diversity analysis using ITS, SSR and ISSR primers. Methods: Reported species-specific primers such as AmF and AmR as well as AaF2 and AaF3 were used for Alternaria species identification. ITS region was amplified through ITS1 and ITS4 and sequences were used for identification and clustering of isolates. Thirteen hyper variable SSR primers specific to Alternaria were designed based on the sequences retrieved from NCBI and used for diversity study. Six different ISSR primers were also used for genetic diversity study. Result: Reported species-specific primers found not suitable to identify A. macrospora and A. alternata at species level. Two SSR primers were found to be effective in showing variability among the isolates. Six clusters were formed at 71 percent genetic dissimilarity among 15 isolates of Alternaria through ISSR primers. Five clusters were formed in ITS sequence’s diversity analysis. Blasting of ITS sequences of 15 selected isolates at NCBI showed that all belong to A. alternata. This was due to absence or presence of very few sequences of A. macrospora in NCBI database itself. Further house-keeping genes like Alt a1, Plasma membrane ATPase, GAPDH and TEF -1 α sequence analysis will be useful for confirmation of A. macrospora at species level.\u0000","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44371496","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}

Methods: The influence of osmotic polyethylene glycol 6000 on the research object C. coggygria regenerants was studied in vitro. Such indicators as morphological changes, pigment content, stomatal density and size and stomatal slit size were quantified. Result: Due to the influence of osmotic stress, there was a pigment content increase in the leaf plate on osmotic media. Stomatal density raised by 27.0-29.8% in explant cells cultivated on PEG 4.0-6.0%. Under the osmotic influence, there was a drop in the stomatal cells’ area and shape and the ratio of stomatal length to width in the regenerant leaves decreased from 1.5 to 1.0-1.1. These results indicate the adaptation of C. coggygria regenerants to stress caused by an artificial drought in vitro.

A careful plan is required to increase the yield and quality of crops. A profound knowledge on the use of organic manure involvement in plant growth and development could be beneficial for food production. The use of acceptable inorganic and different concentrations of vermicompost has been used in an attempt to enhance crop growth and development with the aim of increasing food production. The aim of the study was to investigate the impact of vermicompost tea concentrate extracted from cow manure and grass cutting on physiological responses of tomato (Solanum lycopersicum).Vegetative growth and yield of tomato was stimulated by mineralization of organic waste coupled with the mesophilic action of earthworm. Vermicompost is a by-product of earthworm tissues. It is a nutrient source rich in essential components for plant growth and development. Methods: An investigation was conducted in pot media under exposed natural conditions from August 2020 to November 2020 at Mangosuthu University of Technology. In this experiment, the growth of tomato plants were subjected to different vermicompost concentrations and amended with NPK fertilizer were studied. Sandy loam soil of about 5 kg were weighted into pot media (2.0mheight, 2.3m diameter). The experiment was set up in a completely randomized block design consisting of five treatments with five replicates per treatment. Treatments included: Positive control (PC), 5%VCL+NPK, 10% VCL+NPK, 20%VCL+NPK and the inorganic (NPK). Result: revealed that there were significant differences at (P less than 0.01) among the treatments with respect to plant height and number of leaves from week three to week eight. Similar trends were found with 5% VCL+NPK, 10% VCL+NPK, 20% VCL+NPK and the NPK treatments. This may be due to phytohormone release from earthworm tissue.

Methods: Two soft wheat varieties (Trizo and Sudarynya) were inoculated with Bacillus subtilis 124-11, Pseudomonas fluorescens SPB2137 and Sphingomonas sp. K1B under field conditions during 2017-2021 years. Wheat development was monitored at different stages using a set of indicators characterizing morphological traits and yield structure. Susceptibility of plants to root rot pathogens and leaf diseases (brown and yellow wheat rust, powdery mildew, septoria-pyrenophorous spotting) was analyzed using a number of phytopathological indicators. Result: The maximal increase in yield by 1,14 g plant-1 and 0,87 g plant-1 was revealed after treatments with B. subtilis 124-11 and Ps. fluorescens SPB2137. The minimal ecological variation in wheat productivity elements was observed when B. subtilis 124-11 was used.
