Overexpression of EaALDH7, an aldehyde dehydrogenase gene from Erianthus arundinaceus enhances salinity tolerance in transgenic sugarcane (Saccharum spp. Hybrid).

Aldehyde Dehydrogenases (ALDH), a group of enzymes, are associated with the detoxification of aldehydes, produced in plants during abiotic stress conditions. Salinity remains a pivotal abiotic challenge that poses a significant threat to cultivation and yield of sugarcane. In this study, an Aldehyde dehydrogenase gene (EaALDH7) from Erianthus arundinaceus was overexpressed in the commercial sugarcane hybrid cultivar Co 86032.

Comparative genome-wide characterization of salt responsive micro RNA and their targets through integrated small RNA and de novo transcriptome profiling in sugarcane and its wild relative .

Unlabelled: Soil salinity and saline irrigation water are major constraints in sugarcane affecting the production of cane and sugar yield. To understand the salinity induced responses and to identify novel genomic resources, integrated de novo transcriptome and small RNA sequencing in sugarcane wild relative, salt tolerant accession IND 99-907 and salt-sensitive sugarcane genotype Co 97010 were performed. A total of 362 known miRNAs belonging to 62 families and 353 miRNAs belonging to 63 families were abundant in IND 99-907 and Co 97010 respectively.

Comparative de novo transcriptome analysis identifies salinity stress responsive genes and metabolic pathways in sugarcane and its wild relative Erianthus arundinaceus [Retzius] Jeswiet.

Erianthus arundinaceus [Retzius] Jeswiet, a wild relative of sugarcane has a high biomass production potential and a reservoir of many genes for superior agronomic traits and tolerance to biotic and abiotic stresses. A comparative physiological, anatomical and root transcriptome analysis were carried out to identify the salt-responsive genes and metabolic pathways associated with salt-tolerant E. arundinaceus genotype IND99-907 and salinity-sensitive sugarcane genotype Co 97010.

Delineation of genotype × environment interaction for identification of stable genotypes for tillering phase drought stress tolerance in sugarcane.

Sugarcane is a trans-seasonal long-duration crop and tillering phase (60-150 days) is the most sensitive phase for moisture stress, causing significant reduction in biomass accumulation. The study focussed to assess the Genotype × Environment Interaction (GEI) for tillering phase moisture stress and to identify the stable genotypes in sugarcane. The study dealt with 14 drought tolerant genotypes and two standards (Co 86032 and CoM 0265) which were evaluated in two plant and one ratoon trials at four locations in Maharashtra, India.

Genetics and mapping of seed coat impermeability in soybean using inter-specific populations.

Seed coat impermeability (SCI) in soybean is associated with seed viability under storage and quality of processed products. Understanding genetics and identification of linked molecular markers would facilitate need-based utilization of seed coat impermeability. Two impermeable wild type ( Sieb.
