Production of valuable secondary metabolites through plant cell or organ culture is the best suited alternative to extraction of whole plant material and to increase production of secondary metabolites in in-vitro systems, feeding precursor or intermediate metabolites is an obvious and popular approach. The present investigation was aimed to study the influence of feeding of organic supplements, glycine (0-125 μM), ferulic acid (0-200 μM), phenylalanine (0-200 μM), α-ketoglutaric acid (0-200 μM) and pyruvic acid (0-200 μM) on production of bacoside-A (a triterpenoid type secondary metabolite responsible for cognition effects) in shoot and callus biomass of Bacopa monniera (L.) Pennell. The shoots were raised in liquid Murashige and Skoog's (MS) medium fortified with 5 μM 6-benzyladenine (BA) and callus biomass on agar solidified MS medium containing 1 μM 2,4-dichlorophenoxyacetic acid (2,4 -D) in conjunction with 5 μM 1-napthaleneacetic acid (NAA). Among the organic supplements used, 100 μM pyruvic acid effectively enhanced the production of bacoside-A in shoot as well as callus biomass. The bacoside-A content in in-vitro raised shoot biomass was 4.0 and 1.2 times higher as compared to control and shoot biomass of naturally grown plants respectively. Inclusion of pyruvic acid in MS medium for in-vitro shoot cultures of B. monniera, can be adapted for enhanced production of bacoside-A. © 2010 Prof. H.S.

In the present report attempt is made to in depth survey of the species Sonneratia L. throughout Maharashtra and its analysis for biochemical, elemental composition, species dynamics and the distribution of the species along the coast. Carbohydrate composition varies from species to species. Protein content is more in all the three species followed by polyphenols. The elemental composition is also varies and is species specific. Chlorides concentration in S. alba is more indicating succulence and sulphate requirement in S. apetala indicates its non succulence. Amino acids content in S. caseolaris is more may used in osmoregulation. © 2015, National Institute of Science Communication and Information Resources (NISCAIR). All rights reserved. Source

Two rare species of the longicorn beetle subfamily Lamiinae, Imantocera penicillata (Hope, 1831) and Eutaenia corbetti Gahan, 1893, from Tripura, a province in northeastern India, are redescribed and illustrated. This is the first detailed account of the external morphology of both sexes of the two species. Host plants of the two species are reported for the first time: I. penicillata was collected from Artocarpus heterophyllus Lamarck and E. corbetti was collected from Caesalpinia decapetala (Roth) Alston.

Effect of increasing levels of NaCl and Na 2SO 4 on mineral content in various organs of safflower (Carthamus tinctorius L.) cv. Bhima was investigated at flowering. Results revealed that Dry Matter (DM) per plant decreased with increasing levels of NaCl. DM increased at low levels and decreased at all higher levels of Na 2SO 4 at flowering and maturity. Plants completed life cycle upto ECe 7.5 mS cm -1 of chloride and ECe 10.0 mS cm -1 of sulphate salinity. Plants tolerate all levels of chloride and higher levels of sulphate salinity by storing toxic minerals in roots and basal part of stem and by translocating essential elements to the leaves indicating presence of regulatory mechanism at the junction of root and stem; within the stem and in between the stem and leaves in safflower. © 2012 Asian Network for Scientific Information.

We describe a new species of Leptestheria from a rock pool in the Western Ghats of Maharashtra, India. This species is distinguished from all other Indian congeners by its distinct telson characters and occipital condyle. We also present a comparative table of useful morphological characters of all described Indian Leptestheria species. Copyright © 2016 Magnolia Press. Source
