Heat shock proteins (HSPs) have a major role in stress tolerance mechanisms in plants. Our studies have shown that the expression of HSP70 is enhanced under water stress in Erianthus arundinaceus. In this paper, we evaluate the effects of overexpression of EaHSP70 driven by Port Ubi 2.3 promoter in sugarcane. The transgenic events exhibit significantly(More)
Plant growth during abiotic stress is a long sought-after trait especially in crop plants in the context of global warming and climate change. Previous studies on leaf epidermal cells have revealed that during normal growth and development, adjacent cells interdigitate anisotropically to form cell morphological patterns known as interlocking marginal lobes(More)
In genetic engineering, inducible promoters play an important role as the expression of genes driven by them can be turned on or off under situations like biotic or abiotic factors. There are few reports on inducible promoters that can be employed in the development of transgenic plants, particularly in sugarcane. In the present study, four wound inducible(More)
DNA helicases are motor proteins that play an essential role in nucleic acid metabolism, by providing a duplex-unwinding function. To improve the drought and salinity tolerance of sugarcane, a DEAD-box helicase gene isolated from pea with a constitutive promoter, Port Ubi 2.3 was transformed into the commercial sugarcane variety Co 86032 through(More)
EaDREB2 overexpressed in sugarcane enhanced tolerance to drought and salinity. When co-transformed with plant DNA helicase gene, DREB2 showed greater level of salinity tolerance than in single-gene transgenics. Drought is one of the most challenging agricultural issues limiting sustainable sugarcane production and can potentially cause up to 50 % yield(More)
The myosin superfamily is a versatile group of molecular motors involved in the transport of specific biomolecules, vesicles and organelles in eukaryotic cells. The processivity of myosins along an actin filament and transport of intracellular 'cargo' are achieved by generating physical force from chemical energy of ATP followed by appropriate(More)
Erianthus is a wild relative of the genus Saccharum. It is well known for its high fibre, high biomass, tolerance to drought and water logging, pest and disease resistance with multi-ratooning ability. This study was conducted to investigate physiological and molecular responses of Erianthus spp. to drought stress. Out of seven Erianthus accessions(More)
Myosins are one of the largest protein superfamilies with 24 classes. They have conserved structural features and catalytic domains yet show huge variation at different domains resulting in a variety of functions. Myosins are molecules driving various kinds of cellular processes and motility until the level of organisms. These are ATPases that utilize the(More)
Profile based sequence search methods are widely used to obtain homologous proteins with the usage of stringent statistical measures. These simple searches, albeit their high sensitivity, cannot solely be relied, while searching for protein families with high functional diversity and sharing structural similarity with other families. Myosins are motor(More)
Porteresia ubiquitin 5′ regulatory region drives transgene expression in monocots and dicots. Ubiquitin promoters are promising candidates for constitutive transgene expression in plants. In this study, we isolated and characterized a novel 5′ regulatory sequence of a ubiquitin gene from Porteresia coarctata, a stress-tolerant wild grass species. Through(More)
