A study was conducted to document the floristic composition and biological spectrum of plant species of the Matta-Kharari region, Swat. The region has not been ecologically explored yet. We used quantitative ecological techniques for sampling plant species. Sixty-seven quadrats of 1x1 m2 for herbs, 5x5 m2 for shrubs and 10x10 m2 size for trees were established. Plant species data were analyzed using multivariate statistical techniques. We evaluated 76 plant species belonging to 42 families. Asteraceae and Rosaceae were the leading families with 8 species each, followed by Ranunculaceae, Lamiaceae and Moraceae with 4 species each. Among life form classes i.e., geophytes were dominant (13 species, 17.10 %), followed by therophytes (12 species, 15.87 %), nanophanerophytes (11 species, 14.47 %), and chamaephytes (10 species, 13.58 %). Moreover, Mesophylls (36.84 %) were the dominant leaf spectra class followed by nanophyll (30.26 %), microphyll (27.63 %), and megaphyll (2.63 %). The two-way cluster analysis classified the vegetation into three clusters. The detrended correspondence analysis shows the distribution of plants in a mixed array because the locations explored are characterized by similar climatic factors and vegetation. We elucidate that the variation in climatic factors and topography brings variation in vegetation. Understanding these responses at the life form and leaf spectra level will provide a better understanding and knowledge that how plant species and their communities or associations respond to changes in climate in the future. The current study could be utilized as a baseline for large-scale studies in the future.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43281254","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}

The improvement in water use efficiency at the field level is very important and can redress water scarcity. LASER land leveling is increasing quickly in the world to increase water use efficiency. However, in developing countries, the practice of LASER leveling is to level land or field with zero (0 %) gradient due to unawareness of gradient-based land leveling while a small gradient (e.g., 0.1 %) is usually kept during land leveling in developed countries of the world. But farmers of developing countries are not well, therefore, an experiment was conducted in farmers’ fields covering an area of 3 acres in south Punjab of Pakistan to assess the LASER leveling with a 0 % and 0.05 % grade and general farmer’s practice of leveling. Land leveling with LASER using a 0.05 % gradient considerably decreased the amount of irrigation water and/or enhanced water use efficiency by increasing crop yield followed by LASER leveling with a 0 % gradient. Similarly, with a 0.05 % gradient, bolls per plant and final cotton yield increased considerably followed by a 0 % gradient while minimum bolls per plant and cotton yield were obtained from the farmer’s practice of leveling. LASER land leveling with a 0.05 % gradient resulted in higher net benefit due to increased yield and a considerable decrease in irrigation amount that significantly improved use efficiency. The outcomes suggest that benefits from land leveling with LASER keeping a 0.05 % gradient are significantly higher when compared with 0 % gradient and/or farmers’ practice of leveling.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46352518","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}

T2DM is a chronic disease and a rising problem worldwide. Its complications lead to an increase in the burden of mortality specifically in lower and medium-income countries. Genome-wide association studies have spotted many genetic loci that are related to T2DM and validate the complicated polygenic traits. Many variants of different genes including FTO are associated with T2DM hence, this study was designed to inspect and unfold obscure data in South Asians. The main objective of present study is to identify the relation of FTO intronic variant rs9939609 with T2DM in Karachi-based Sindhi population of Pakistan. Total recruited individuals were grouped as diabetic cases and controls. Out of the total recruited subjects, genotyping was done on 152 samples using T-ARMS PCR however, demographic and clinical data were recorded of all individuals. The results showed that the frequency of variant genotypes in the diabetic case group was 11 % for AA, 45 % for AT and 44 % for TT though, the frequency of the lethal allele (T) was 34 %. These outcomes concluded, rare T allele frequency is higher among diabetic cases as compared to controls and provides the contribution from the Pakistani population to support the previous controversial findings. This study concluded FTO gene-single nucleotide polymorphism, rs9939609 is associated with T2DM but still, it is a growing need to do further studies on T2DM susceptible genes with different polymorphisms to recognize targets in the field of pharmacogenomics for clinical implementation.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47607105","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}

The current study aimed to determine the variation in growth traits and fluctuations in the allocation patterns with respect to different habitats across the altitudinal gradient. In order to adapt to unpredictable and stressful conditions at higher altitudes, phenotypic plasticity plays a crucial role. Our findings revealed considerable variability in the phenotypic traits, indicating that altitude has a defined effect on this specific species’s morphology and reproductive traits. Low altitude plant populations of Kashmir University Botanical Garden (KUBG), Dara and Tangmarg were more robust and taller (98.4±2.36, 83.58±2.69 and 74.08±1.59 cm, respectively) than the populations of Pissu top and Bangus (23.96±3.38 and 30.43±1.12 cm respectively) at higher altitudes. The habitats of KUBG, Dara, and Tangmarg proved to be substantially better for the growth of B. amplexicaulis, as per the Principal component analysis (PCA). The regression analysis demonstrated a negative relation between altitude and plant height. Traits such as leaf length/ breadth, Rhizome length/ breadth and inflorescence length showed a strong correlation with plant height.

Researchers are now turning attention towards fibrinolytic enzymes as potential alternative treatment for thrombolytic diseases. This present study focused on the production of extracellular fibrinolytic enzyme from soil Actinobacteria and evaluation of its hydrolytic activity on blood clot. The Actinobacteria was isolated from compost soil of semi-arid climate in Nigeria. Bacterial isolation was achieved using starch casein agar. Potent fibrinolytic enzyme producing Actinobacteria were identified and subjected to enzyme production using submerged fermentation method. The interactive effects of incubation time, temperature, pH and media components on enzyme production were analysed. Extracellular fibrinolytic enzyme produced by the selected Actinobacteria was partially purified by ammonium sulphate precipitation and subsequently assayed for blood clot lysis activity. Results of these studies indicated that fibrinolytic enzyme was produced optimally at pH 8 and temperature of 40 oC after 72 hour of fermentation. Partially purified fibrinolytic enzyme was able to degrade blood clot comparable to the positive control. These results shows that soil Actinobacteria of unexplored semi-arid climate of Nigeria present a prospect in search of novel microorganisms with potentials in the production of fibrinolytic enzyme that can serve as an alternative blood clot buster in treating thrombolytic diseases.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47151510","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}
