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)
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)
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)
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)
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)
The genus Cenchrus comprises around 25 species of ‘bristle clade’ grasses. Cenchrus ciliaris (buffel grass) is a hardy, perennial range grass that survives in poor sandy soils and limiting soil moisture conditions and, due to the very same reasons, this grass is one of the most prevalent fodder grasses of the arid and semi-arid regions. Most of the(More)
BACKGROUND Cytoplasmic class XI myosins are the fastest processive motors known. This class functions in high-velocity cytoplasmic streaming in various plant cells from algae to angiosperms. The velocities at which they process are ten times faster than its closest class V homologues. RESULTS To provide sequence determinants and structural rationale for(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)
Sucrose phosphate phosphatase (SPP) is the last enzyme of sucrose biosynthetic pathway that generates sucrose in an irreversible reaction of sucrose phosphate hydrolysis. Different photosynthetic species have different cytoplasmic sugar levels that can be attributed partly to the variation in specific activity, stability, pH specificity etc. of this key(More)
Sucrose is an important storage form of assimilated carbon in many plant species. Unlike other sucrose biosynthetic enzymes, Sucrose Phosphate Phosphatase (SPP), the terminal enzyme in sucrose biosynthetic pathway, is the least understood. SPPs from different organisms have different kinetic properties. The current study focuses on the structural(More)
