An analysis of the nucleotide sequences of the 16S rRNA and rpoD genes identified the Pseudomonas sp. 17 НМ strain as Pseudomonas capeferrum, and the strains of Pseudomonas sp. 65 НМ and 67 НМ were most closely related to the type strains of Pseudomonas silesiensis and Pseudomonas umsongensis, respectively. It was shown that the strains of Pseudomonas sp. 17 НМ, 65 НМ, and 67 НМ were characterized by different levels of resistance to heavy metals, with the maximum tolerable concentration (MTC) of zinc being 1 mМ for all strains, that of cadmium, 1, 1.5, and 1 mМ; of lead, 5, 5, and 4 mМ; and of nickel, 7, 9, and 7 mМ, respectively. All Pseudomonas strains can form biofilms and have the properties of PGPR bacteria. Treatment of alfalfa seeds (Medicago sativa L.) with the strains of Pseudomonas sp. 17 НМ, 65 НМ, and 67 НМ under cadmium stress increased the dry weight of alfalfa seedlings up to 40% and the content of chlorophyll a and b in the leaves by 25–33% relative to the control.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"59 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142187796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted in from April 2020–March 2022. A total of 85 bird species belonging to 43 families were observed during the study period. The most abundant families were Motacillidae with Six species, followed by Cisticolidae, Columbidae, Muscicapidae, Sturnidae with five species each. Out of total 73 residents and 10 winters migratory and 2 summer migratory species were identified. The percentage of resident, winter visitor and Summer Migratory avian species was found to be 85.58, 11.76 and 2.35% respectively. The Analysis of RDi (relative diversity) results indicated that the family Motacillidae was the most diverse family, with the highest RDi value of 7.1. Total three avian species namely Red-vented bulbul (Pycnonotus cafer) and Rock Pigeons (Columba livia) and Rose-ringed parakeet (Psittacula krameri) were dominantly spared in the University Campus. One species Alexandrine Parakeet (Psittacula eupatria) which observed during the study falls under the Near Threatened (NT) category. The results of the study reflect the importance of such areas as important bird habitats where various local and migratory birds are found to rest and feed.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"48 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salammbô) grown in the presence of 100 mM NaCl. AsA or Pro supplementation ameliorated wheat seedlings’ growth and increased parameters that were reduced by salinity. Relative water content, total chlorophyll, K+ and total carbohydrates contents as well as K+/Na+ ratio and root-to-shoot K+ translocation were significantly increased. Osmoprotectant contents were remarkably accumulated, whereas Na+ content and root-to-shoot Na+ translocation were significantly declined. Additionally, exogenous AsA or Pro application enhanced the antioxidant defense system components and insured better oxidative stress tolerance, as indicated by reduced H2O2 production and lipid peroxidation, resulting in an increased membrane stability index. Such effects were further enhanced following the simultaneous application of AsA and Pro, resulting in a better growth, as compared to single applications of these substances. Taken together, findings of this study provide strong arguments highlighting the potential synergy between exogenously applied AsA and Pro in mitigating the adverse effects of salt stress of wheat plants at the early seedling stage.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"40 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test the hypothesis, moth samples are collected from 11 sites in three districts of Arunachal Pradesh and West Bengal, North East India. Pollen of 18 angiosperm families are isolated from the proboscides of 16 moth species in four families. We selected proboscides for the isolation of pollen because it is the most important organ of moths which interacts with flowers during moth visitation. The isolated pollen is studied for various morphological characters like pollen shape, unit, exine ornamentation, thickness, aperture numbers, and aperture types along with specialized structures i.e., viscin thread and pollenkitt, and analyzed for their attachment on the proboscides. The present study revealed the significant role of pollen shape, unit, exine characters, viscin thread, and pollenkitt in attachment with proboscides. Whereas, the aperture numbers and aperture types are found insignificant in the process of pollen attachment. Studies on the formation of viscin thread and pollenkitt may be established as an important tool to understand the specialized and generalized interactions between moths and angiosperms. The present study will open up a new horizon in pollination ecology.","PeriodicalId":55366,"journal":{"name":"Biology Bulletin","volume":"2010 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141609214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
