Ectopic expression of choline oxidase () gene from confers drought stress tolerance in transgenic sugarcane.

Unlabelled: Drought is a serious problem that impacts sugarcane production and productivity worldwide. In this current investigation, a codon-optimized choline oxidase () gene was transformed into hybrid cultivar Co 86032 through -mediated transformation. The transgenic events with the gene driven by the portubi882 (PD2) promoter accumulated elevated levels of glycine betaine (5 - 10µg/g) whereas untransformed control plants accumulated less than 1.

Isolation, characterization and expression analysis of stress responsive plant nuclear transcriptional factor subunit () from commercial hybrid and wild relative .

Plant nuclear factor () is a transcription activating factor, consisting of three subunits, and plays a key regulatory role in many stress-responsive mechanisms including drought and salinity stresses. NF-Ys function both as complex and individual subunits. Considering the importance of sugarcane as a commercial crop with high socio-economic importance and the crop being affected mostly by water deficit stress and salinity stress causing significant yield loss, nuclear transcriptional factor was focused in this study.

Differential gene expression profiling through transcriptome approach of L. under low temperature stress reveals genes potentially involved in cold acclimation.

Sugarcane ( sp.) is predominantly grown in both tropics and subtropics in India, and the subtropics alone contribute more than half of sugarcane production. Sugarcane active growth period in subtropics is restricted to 8-9 months mainly due to winter's low temperature stress prevailing during November to February every year.
