BioProfile- Memory Enhancer

53-54The word Acorus is derived from the Greek word ‘acoron’, which in turn is derived from ‘coreon’ meaning pupil and refers to the alleged ophthalmic virtues of the plant. Calamus originated from a Greek word ‘kalamos’, meaning ‘reed’. In Sanskrit it is commonly called kalama, meaning ‘reed’ and ‘pen’ as well as a sort of rice. It is a small genus of herbs, comprising two species viz. Acorus calamus and Acorus gramineus, found in the North temperate regions and South-East Asia

Response of Populus deltoides Bartr. ex Marsh genes under elevated CO2 through Next-Generation Sequencing (NGS)

The impact of climate change has attracted considerable attention globally. Atmospheric Carbon Dioxide (CO2) is expected to increase to 900 μmol mol-1 from present level of 400 μmol mol-1 by the end of 21st century. CO2 is a greenhouse gas that leads climate change have significantly affected structure and function of the terrestrial ecosystem, global carbon, water balance, and also crop productivity. These responses of the plant appear by altering gene expression pattern of different genes involved in anabolic and catabolic processes. We have conducted a study to see the response of genes to elevated CO2 inside open top chambers on Populus deltoides. Onemonth- old ramets were exposed for 180 days to treatment (CO2 800 μmol mol-1) and control (CO2 ~400 μmol mol-1). After completion of treatment, leaf tissues were outsourced to Sci-genome for transcriptome sequencing. This study demonstrated, higher (1754) number of transcript expression in treatment (119,306) compared to control (121,060). Differential gene expression analysis shown 1951 transcripts were down regulated while 2603 transcripts up regulated and 159,982 transcripts have no significance in treatment. Our results show that plants growing in an environment where atmospheric CO2 is higher may alter plant adaptation, productivity, vegetation and ecosystem health by changing; the first, number of genes and second, altering gene expression patterns. Such behavior may be a good indicator of developing adaptation strategies of the plant

Foliar chemical attributes of the hybrid bred from Eucalyptus citriodora x E. torelliana and its parental taxa, and implications for fungal resistance

<span>One of the important aspects of hybridization is to understand the interaction between hybrid plants and the pests and diseases of the parental taxa. The foliar chemical attributes were compared between the hybrid of </span><em>Eucalyptus citriodora</em><span> and </span><em>E. torelliana</em><span> and its parental taxa. The fungus, </span><em>Cylindrocladium quinqueseptatum</em><span>, to which the hybrid and one parent </span><em>E. torelliana</em><span> have been observed resistant in the field, was used to examine patterns of resistance in relation to foliar constituents found active in labo-ratory bioassays. Concentration of active constituents of the hybrid was higher (monoterpenes- a-pinene, ß-pinene and citronellal, and total phenolics) than either parent or equivalent (ursolic acid) to parent E. torelliana thus suggesting an resistance pattern of hybrid. Beta-pinene, ursolic acid and total phenolics were found to be heritable. The findings suggest a chemical basis for fungal resistance and also indicate that the constituents could be used for screening of the disease resistant progeny in this tree system. </span
