In Silico Identification of Conserved Domains from EST Database in Safflower
M. Y. Dudhe, H. P. Meena, A.R.G. Ranganatha, N. Mukta and C. Lavanya

Identified conserved domains or gene families from the ESTs could be utilised for the identification of gene-targeted markers and for development of functional markers to accelerate marker assisted backcross breeding in safflower.

Quercetin Accumulation is Associated with Drought Resistance in White Clover
Ballizany, W.L 1, Hofmann, R.W. 1, Jahufer, M.Z.Z. 2, Barrett, B.A. 2

White clover is an important pasture legume, but growth is often strongly reduced under summer drought. Abiotic stress is mediated by the induced production of flavonoids. At the individual genotype level, increased flavonol (quercetin) accumulation in response to water deficit stress is positively associated to retaining higher levels of dry matter production.

Drought Induced Increase in Quercetin Glycosides is Associated with Drought Resistance in a Novel White Clover Population
Wouter L. Ballizany, Rainer W. Hofmann, Brent A. Barrett, Zulfi Jahufer

White clover is an important forage legume in temperate pastures, but does not have sufficient resistance against drought stress. Quercetin is a flavonol conferring plant sunscreen and anti-oxidant properties under UV-B stress with a trade-off of reduced biomass. An F1 full-sib cross between stress tolerant and stress sensitive white clover genotypes showed the ability to increase Q accumulation associated to maintenance of dry matter yield under a near wilting drought.

SUBSTITUTION OF FERTILIZER NITROGEN THROUGH ORGANIC SOURCES IN MAIZE -WHEAT CROPPING SYSTEM IN INDO-GANGETIC PLAINS
N.K. Jat1* and Ashok Kumar2

• Application of SGM either alone or in combination with WS with moderate levels of fertilizer N substitute for substantial amount of fertilizer N and consequently enhanced crop productivity with higher profitability maintaining soil fertility in maize-wheat cropping system. Application of leguminous green manure and previous crop residues (wheat residues) in soil can potentially deal the issues of stagnation in productivity, declining factor productivity and soil fertility depletion.

Potential of the strain of entomopathogenic fungus Isaria fumosorosea CCM 8367 as a biological control agent against Cameraria ohridella and other pests
Eva Prenerova, Rostislav Zemek, Frantisek Weyda, Lubomir Volter, Mona Awad and Hany M. Hussein

Strain CCM 8367 of Isaria fumosorosea (syn. Paecilomyces fumosoroseus) was isolated in the Czech Republic from lepidopteran pest and is deposited as a patent culture in the Czech Collection of Microorganisms in Brno. The aim of our study was to evaluate the effect of this strain on Cameraria ohridella, Leptinotarsa decemlineata and Spodoptera littoralis. Comparison with Apopka 97 strain isolated from commercial biopesticide PreFeRal WG (Biobest, Belgium) was made.

Hybridization between native and introduced Rubus in California and the Pacific Northwest
Lindsay V. Clark and Marie Jasieniuk

Given the sympatry of native and non-native Rubus in the Western United States, we are interested in the potential of novel hybridization events to contribute to the evolution of invasiveness in this genus. Using SSRs, we identify hybrids between native and non-native species, as well as multiple clones of the invasive R. armeniacus.

Microsatellites distinguish sexual vs. apomictic reproduction in spontaneous Rubus hybrids
Lindsay V. Clark and Marie Jasieniuk

In previous work we identified spontaneous hybrids between the native, sexual R. ursinus and the non-native, apomictic R. armeniacus and R. pensilvanicus. Using microsatellite genotypes of seeds and seedlings, we determine that the hybrids produce a mix of sexual and clonal offspring, and that sexual seeds have higher viability. This has implications for the ability of hybrid Rubus to evolve into new invasive forms.

SILENCING THE SAM PATHWAY GENES RELATED TO CAFFEINE PRODUCTION IN TEA
NEELAKSHI BHATTACHARYYA, H. Ranjit Singh, Prasenjit Bhagwati, Chiranjana Borah, Sangeeta Borchetia, Niraj Agarwal, Priyadarshini Bhorali, Bornali Gohain, Raju Bharalee, Tirthankar Bandyopadhyay, Sushmita Gupta, Sourabh Kumar Das, Parveen Ahmed, and Sudripta Das

Caffeine (1,3,7-trimethyl xanthine), known to have sensory and stimulatory effects, causes adverse effects on health which has resulted in an increased demand for de-caffeinated tea. The transformants obtained by RNAi are being analysed for partial and complete knockdown of one or both the genes using RT-PCR and reduction in caffeine production estimated by HPLC.

A FUNCTIONAL GENOMIC APPROACH TO ANALYZE HERBIVORY RELATED TRANSCRIPTS IN TEA
PARVEEN AHMED, Tirthankar Bandyopadhyay, Priyadarshini Bhorali, H. Ranjit Singh, Bornali Gohain, Raju Bharalee, Sushmita Gupta, Sourabh Kumar Das, Niraj Agarwal, Prasenjit Bhagwati, Neelakshi Bhattacharya, Sangeeta Borchetia and Sudripta Das

Tea Mosquito Bug (Helopeltis theivora Waterhouse) is one of the most dreaded tea pests of NE India causing a loss of 15-20 lakh kgs of made tea per year. SSR markers derived from stress associated ESTs were evaluated in a segregating population showing variable resistance to Helopeltis infestation. This approach would facilitate new methods of marker assisted selection (MAS) to efficiently breed superior Helopeltis resistant varieties.
