Deep sequencing of suppression subtractive library identifies differentially expressed transcripts of Saccharum spontaneum exposed to salinity stress.

Saccharum spontaneum, a wild relative of sugarcane, is highly tolerant to drought and salinity. The exploitation of germplasm resources for salinity tolerance is a major thrust area in India. In this study, we utilized suppression subtractive hybridization (SSH) followed by sequencing for the identification of upregulated transcripts during salinity stress in S.

High-throughput miRNA deep sequencing in response to drought stress in sugarcane.

Unlabelled: Drought is a major factor which reduces cane growth and productivity. In the present study, we sequenced drought susceptible (V1) and drought tolerant (V2) sugarcane varieties using high-throughput miRNA deep sequencing method to study the regulation of gene expression by miRNAs during drought stress in sugarcane. A total of 1224 conserved miRNAs which belong to 89 miRNA families were identified and 38% of the differentially regulated miRNAs were common for both varieties.

Gene expression studies of Saccharum spontaneum, a wild relative of sugarcane in response to salinity stress.

The study is aimed to assess the morphological, physiological, and molecular responses of seven Saccharum spontaneum clones for salinity stress. These clones (IND-07-1462, IND-07-1465, IND-07-1470, IND-07-1471, IND 16-1761, IND 16-1762, and IND 16-1763) were subjected to salinity stress at two different concentrations of electrical conductivity 6 and 8 ds/m after 60 days of planting. All seven genotypes showed a decrease in relative water content and nitrate reductase activity with an increase in severity of salt stress.

Isolation, cloning and expression analysis of cinnamyl alcohol dehydrogenase (CAD) involved in phenylpropanoid pathway of a wild relative of sugarcane.

In this study we have cloned and characterized cinnamyl alcohol dehydrogenase (CAD) involved in phenylpropanoid pathway which can be utilized for biomass modification for improved saccharification efficiency. The full length gene CAD is of 4 kb containing four exons and three introns, among which the exon 1 and 2 of 88 and 116 bp were conserved with sorghum and CADs. The coding region of CAD was identified with 1098 bp open reading frame (ORF), for 365 amino acids.
