Drought is one of the most challenging agricultural issues limiting sustainable sugarcane production and, in some cases, yield losses caused by drought are nearly 50%. DREB proteins play vital regulatory roles in abiotic stress responses in plants. The transcription factor DREB2A interacts with a cis-acting DRE sequence to activate the expression of downstream genes that are involved in drought...

Increasing drought is one of the most critical challenges facing species and ecosystems worldwide, and improved theory and practices are needed for quantification of species tolerances. Leaf water potential at turgor loss, or wilting (π(tlp) ), is classically recognised as a major physiological determinant of plant water stress response. However, the cellular basis of π(tlp) and its importance ...

Pressure-volume curves and shoot water potentials were determined for black spruce (Picea mariana (Mill.) BSP) trees from four full-sib families at the Petawawa Research Forest, Ontario, Canada. Trees were sampled from a dry site in 1992 and from the dry site and a wet site in 1993. Modulus of elasticity (epsilon), osmotic potential at turgor loss point (Psi(tlp)) and relative water at turgor l...

OBJECTIVE To determine the incidence, severity and nature of injuries sustained during the Rugby World Cup (RWC) 2015 together with the inciting events leading to the injuries. DESIGN A prospective, whole population study. POPULATION 639 international rugby players representing 20 countries. METHOD The study protocol followed the definitions and procedures recommended in the consensus sta...

Metallic tubes, under axial loading, are frequently preferred in many different industries due to their high energy absorption efficiency. The studies increase the capacity (EAC) of these structures still up date. In this study, deformation behavior and EAC regionally pre-deformed identical aluminum steel tubes loading were investigated experimentally. Regional strength was obtained by radial w...

Lichens can survive and cope with unsufficient water supply resulting in low intrathalline relative content. Under such conditions, photosynthesis is negatively affected by different degree of dehydration. In our study, fully hydrated samples Xanthoria elegans, Umbilicaria decussata Usnea aurantiaco-atra were light-acclimated during following desiccation from a to dry state, steady-state chloro...

Two barley cultivars were subjected to water stress by immersing their root system in PEG 6000. The relative water content (RWC) of the leaves fell under these conditions and membrane disorganisation was evidenced by the injury index data. The two genotypes differed in their leaf water content under the applied stress. The aim of this work was to examine the relationship between proline accumul...

Study Design: Descriptive epidemiology study. Methods: Injury data for all players (n 1⁄4 78) selected for 1 national Rugby Union team over a 3-year period were analyzed using the international consensus statement methods. Player height (cm) and mass (kg) were recorded. Tournaments were grouped for comparisons as: autumn tournaments (2012 and 2013), Rugby World Cup (RWC; 2011), Six Nations (201...

Identifying gene interactions and markers associated with physiological traits, especially at later stages of grain filling, can help develop effective breeding methodology in wheat crop. Six generations (P1, P2, F1, F2, BC1P1 BC1P2) four different spring crosses (drought-responsive x drought susceptible) F3 generation a single cross, i.e., MACS6272 UP2828 were phenotyped genotyped to decipher ...
