The population structures among the root (wilt) disease-resistant and susceptible coconut palms from 12 locations in the three disease-endemic districts of southern Kerala, were analyzed using nine microsatellite markers. The pair-wise population differentiation estimate (Fst) between the resistant and susceptible populations was 0.021. Two major populations and a subpopulation cluster were identified among the resistant palms. The analysis of genetic relatedness between the resistant mother palms showed that most of the palms located in a single locality shared sib relationship among them. The existence of close genetic relationship among resistant palms from Chengannur, Thiruvalla, Kottayam and Pavukkara localities in Kerala were reported. The results are discussed in terms of breeding strategies for increasing heterozygosity and obtaining the maximum number of disease-resistant seedlings. Source

Rhizoplane mycoflora of Gymnacranthera farquhariana, Knema attenuata, Myristica dactyloides, M. fatua var. magnifica and M. malabarica was studied by root washing and root plating methods. The root samples along with adhering soil were collected from the rhizosphere regions of each tree species in three seasons - summer, monsoon and post-monsoon - over a period of two years from the forests of Gersoppa, Uttara Kannada district of Karnataka. Soil physico-chemical properties, including moisture, temperature, pH, electrical conductivity, and organic matter and total N, P, K, Ca, Cu, Fe, Mn, Mg, Na and Zn content, were also analyzed. A total of 37 species of fungi were isolated from the rhizoplane region of five tree species. Sørensen's index showed the similarity between the mycoflora of rhizoplane regions to range from 34.6 to 54.6%. Among the five tree species, a maximum of 24 fungal species were isolated from the rhizoplane of K. attenuata and M. fatua var. magnifica, followed by 22 species in M. dactyloides and M. malabarica, and 20 species in G. farquhariana. Nine species were common to the rhizoplane of all the five tree species and nine species were observed in the rhizoplane of only one of the five tree species. The maximum number of fungal species was recorded during monsoon in all plant species and the minimum during post-monsoon and summer. The physico-chemical properties of the rhizosphere soil differed among plant species in different seasons. The dominant genera in terms of number of fungal species were Penicillium and Aspergillus. The rhizoplane fungal population for each plant species in different seasons was correlated with physico-chemical properties of respective seasons, and found that it was significant in some of the seasons or for some parameters only. © International Society for Tropical Ecology.

Introduction: Micronutrients are nutrients which are required by humans and other living beings throughout life in small quantities, to orchestrate a whole range of physiological functions, which the organism itself cannot produce. Therefore, the present study was undertaken to evaluate the status of the micronutrients, oxidative stress, and the lipid profile in healthy adults. Materials and Methods: The present study was conducted after getting the institutional ethical clearance and informed written consents from all the participants. The estimation of copper and zinc was done by the atomic absorption spectrophotometer method,the total antioxidant status was assessed by the phosphomolybdenum method, MDA was evaluated by the Malondialdehyde method, total cholesterol was evaluated by the CHOD-POD method, HDL-cholesterol was evaluated by the precipitation end point method, and total triglycerides were evaluated by the GPO-POD method. The data was analysed by one way ANOVA, followed by Pearson's correlation. Result: We observed significantly increased (p <0.0001) copper and zinc levels in males and females as the age advanced, significantly increased (p <0.01) MDA and TAS levels, significantly declined (p <0.04) total triglyceride levels in adults, significantly declined (p <0.05) HDL levels and significantly declined (p = 0.04) VLDL levels in adults as the age advanced, in both the sexes. Conclusion: The increase in the levels of the micronutrients may have a direct correlation with the oxidative status as the age advances. Source

The title compound, C20H20N2O, was studied as a part of our work on pyrazoline derivatives. It represents a trans-isomer. The central pyrazoline ring adopts an envelope conformation with the asymmetric C atom having the largest deviation of 0.107(1)Å from the mean plane. It forms dihedral angles of 6.2(1) and 86.4(1)° with the adjacent p-tolyl and styrene groups, respectively. In the crystal, C - H⋯O interactions link molecules into infinite chains along the c axis.

The title compound, C19H21N3O, comprises a central pyrazole ring which is N-connected to an aldehyde group and C-connected twice to substituted benzene rings. The pyrazole ring is twisted on the C - C single bond, and the least-squares plane through this ring forms dihedral angles of 82.44(5) and 4.52(5)° with the (dimethylamino)benzene and p-tolyl rings, respectively. In the crystal, weak C - H⋯O hydrogen bonds link molecules into supramolecular tubes along the b axis. Source
