    Chromosome study on Tectaria zeilanica (Houtt.) Sledge which is confined to south India shows the presence of 80 regular bivalents in each spore mother cell (n=80, 4x). This is the first chromosome number report for this species from Tamil Nadu and it seems to be of tetraploid sexual species. It has been collected from Elumpilanthottam, Kanyakumari district of Southern Western Ghats of Tamil Nadu.

    Free filaments of anthers (polyadelphous stamens) and other associated traits such as elongated keel petals wrapped over the wings and the standard considerably delay opening of floral buds, ensuring total self-fertilization in a pigeonpea genotype, ICPL 87154. Inheritance of free filaments and other associated traits of ICPL 87154 were studied in the F1, F2, BC1F1 and BC2F1 generations of its two crosses with high-yielding long-duration pigeonpea varieties, IPA 203 and Bahar. The results suggested that free filaments of anthers in the genotype ICPL 87154 are controlled by double recessive “cleisto” genes, pct1pct1 pct2pct2. Backcross derived advance breeding lines with such selfing attributes showed zero per cent natural outcrossing, thus spontaneously sustaining their genetic purity. Two such lines (RCEA 14-1 and RCEA 14-5) with yield potential comparable to the high yielding parent (IPA 203) were selected for further use.

    A pot experiment was conducted to observe the response of Vigna radiata plants to auxins (IAA and/or 4-Cl-IAA) and their interaction with 24-epibrassinolide (EBL). At 30-day stage of growth, foliar spray of 10-8 M IAA, 4-Cl-IAA, and/or EBL were given. The plants were then allowed to grow for 45 days and were finally harvested to evaluate plant growth, leaf gas exchange traits and selected biochemical parameters. The plants gave positive response to the hormones (IAA, 4-Cl IAA and EBL) applied alone or in various possible combinations. Combined dose of all the three (IAA + 4-Cl IAA + EBL) generated maximum values for all the parameters observed. The lowest readings were recorded in the plants applied with water solely.

    Anacardic acid (AA), has been described as potential antioxidant and Nrf2 is knowing as transcription factor responsible for synthesis of antioxidants proteins. The objective this study was verify the power antioxidant of AA, utilized frog palate epithelium as model of mucociliary epithelium and H2O2 as potent oxidative specie:1) Control Group (CG) - Ringer’s solution (RS)/90’ (n=8); 2) H2O2 (100 mM)/90’ (n=14; 3) AA (50mg/kg)/30’ and RS/90’ (n=4); 4) AA (50mg/kg)/30’ and H2O2 (100 mM)/90’ (HA) (n=4). It was studied the mucociliary transport (MT), ciliary beat frequency (CBF), mucus profile (MP) and expression of Nrf2 (nucleus and cytoplasm). MT and CBF were evaluated through Two-Way ANOVA from two factors: time and treatment. MP and Nrf2 localization were evaluated by One-Way ANOVA test or Kruskal Wallis (p<0.05). MT was significant to time and treatment (p<0.001), CBF only treatment (p<0.001). MP was significant between AH and H2O2 for acid mucus (p = 0.008) and vacuoles between H2O2 and CG (p = 0.003). Nrf2 was different with relation nuclei between H2O2 and CG (p=0.048) and H2O2 and AH related with cytoplasm (p=0.003). AA showed to have a protective effect against reactive oxygen species without requirements of transcription factor Nrf2 translocate to nucleus.

    The need to cut the CO2 immission into the atmosphere is pushing scientists and technologists to discover and implement new strategies that may be effective for controlling the CO2 atmospheric level (and its putative effects on Climate Change-CC). One option is the capture of CO2 (from power plants flue gases or other industrial processes) for avoiding that it can enter the atmosphere. The captured CO2 can be either disposed in natural fields (geological cavities, spent gas or oil wells, coal beads, aquifers; even oceans have been proposed) or used as source of carbon in synthetic processes.
    In this paper we present the options for CO2 utilization driven by solar energy and make an analysis of a variety of solutions for the conversion of large volumes of CO2 by either combining it with H2, that must be generated from water, or by directly converting it into fuels by electrolysis in water, or else by integrating catalysis and biotechnology for an effective conversion of CO2. A CO2-H2 based economy may address the issue of reducing the environmental burden of energy production, also saving fossil carbon for next generations. The enhanced growth of aquatic biomass is not discussed in this paper.

    The analysis of genetic variability and divergence was carried out for nine field peas genotype in the Pulses Research Center, Ishurdi under Bangladesh Agricultural Research Institute (BARI), Bangladesh. The experiment was conducted randomly in complete block design (RCBD), with 3 replicas. Observations were recorded on different yield and yield contributing characters. All cultivars showed considerable differences in their performance, indicating the presence of extensive changes in genotypes for most parameters. The highest yield of pods was BFP 11015, followed by Bagha local and Jhikargachha local. The PCV for all the characters was uninterrupted from their respective GCVs. High GCV as well as PCV were observed for the number of pods per plant, 100 seed weight, powdery mildew severity and pod yield, indicating the existence of a broad genetic basis. The High values of heritability with high genetic advance over percent mean were observed for all traits except days to maturity. Plant height and maturity days showed a positive correlation and a significant correlation for seed yield and a negative correlation with a character yield of 100 seed weight. By using principal component analysis first 3PCs were presented variance for 92.37% of the total variation. First, two PC’s were used to build the biplot in which the genotypes such as, 1-IPSA motorsuti-3, 2-Jhikorgachha local, 4-Faridpur local, 7-BFP 11016 are scattered in four quadrants representing the most genetic divergence. Considering the yield, BFP 11015 and Bagha local genotypes are recommended for releasing as a variety and Jhikargachha local, Faridpur local & BFP 11016 are using crossing materials for advanced genetic material.
