is a specialist aphid of the Indian subcontinent that causes significant yield losses in oilseed Brassicas. Several aphid genes have been used as preferred targets in RNAi-based transgenic plants for aphid resistance. In order to enhance the repertoire of potential target genes for aphid control and to identify the genes associated with aphid feeding and development, we performed a two-way comparative study of differential gene expression profiles between (i) feeding and non-feeding adults and (ii) adult and nymph developmental stages of De novo RNA-seq of aphids using Illumina technology generated a final transcriptome comprising 52,652 transcripts.

Coleoptile is the small conical, short-lived, sheath-like organ that safeguards the first leaf and shoot apex in cereals. It is also the first leaf-like organ to senesce that provides nutrition to the developing shoot and is, therefore, believed to play a crucial role in seedling establishment in rice and other grasses. Though histochemical studies have helped in understanding the pattern of cell death in senescing rice coleoptiles, genome-wide expression changes during coleoptile senescence have not yet been explored.

Proper management of agricultural disease is important to ensure sustainable food security. Staple food crops like rice, wheat, cereals, and other cash crops hold great export value for countries. Ensuring proper supply is critical; hence any biotic or abiotic factors contributing to the shortfall in yield of these crops should be alleviated.

The natural cysteine to serine variation at position 31 of Tat in HIV-1C disrupts the dicysteine motif attenuating the chemokine function of Tat. We ask if there exists a trade-off in terms of a gain of function for HIV-1C Tat due to this natural variation. We constructed two Tat-expression vectors encoding Tat proteins discordant for the serine 31 residue (CS-Tat vs.

Plant-parasitic root-knot nematode uses an array of effector proteins to establish successful plant infections. and are two known effectors secreted from nematode subventral oesophageal glands; being a putative secretory venom allergen AG5-like protein, whereas is a pioneer gene with a coiled-coil motif. Expression of specific effector is known to cause disturbances in the expression of other effectors.

The rice root-knot nematode Meloidogyne graminicola has emerged as a devastating pest of rice in South-East Asian countries. Here we present a draft genome sequence for M. graminicola , assembled using data from short and long insert libraries sequenced on Illumina GAIIx sequencing platform.

Root-knot nematodes are devastating pathogens of crop plants. The draft genome of southern root-knot nematode was published in 2008 and additional genome and transcriptome data became available later on. However, lack of a publically available annotation for genome and transcriptome(s) limits the use of this data for functional and comparative genomics by the interested researchers.

Advent of Next Generation Sequencing has led to possibilities of de novo transcriptome assembly of organisms without availability of complete genome sequence. Among various sequencing platforms available, Illumina is the most widely used platform based on data quality, quantity and cost. Various de novo transcriptome assemblers are also available today for construction of de novo transcriptome.

The role of Mithramycin as an anticancer drug has been well studied. Sarcoma is a type of cancer arising from cells of mesenchymal origin. Though incidence of sarcoma is not of significant percentage, it becomes vital to understand the role of Mithramycin in controlling tumor progression of sarcoma.
