The potential of using pre-stress NaCl or CaCl2 applications to confer a cross-tolerance to a water deficit was evaluated in periwinkle.The plants initially received five applications of NaCl (0, 30 and 50 mM), or CaCl2 (15 and 25 mM) via irrigation, and then they were cultivated under different water deficit regimes (80, 50 and 20% available water

Summary: Thirteen-lined ground squirrels and Syrian hamsters are known for their ability to withstand cold during hibernation.We found that hibernators exhibit cold tolerance even in the active state.Imaging and electrophysiology of squirrel somatosensory neurons reveal a decrease Butterfly Wings Dining / Bar Chair in cold sensitivity of TRPM8-expr

X inactivation--the transcriptional silencing of one X chromosome copy per female somatic cell--is universal among therian mammals, yet the choice of which X to silence exhibits considerable variation among species.X inactivation strategies can range from strict paternally inherited X inactivation (PXI), which renders females haploid for all matern

Abstract Background In the fall, Eastern North American monarch butterflies (Danaus plexippus) undergo a magnificent long-range migration.In contrast to spring and summer butterflies, fall migrants are juvenile hormone deficient, which leads to reproductive arrest and increased longevity.Migrants also use a AMBER OIL time-compensated sun compass to

Abstract Background Detailed modelling of the neutral mutational process in cancer cells is crucial for identifying driver mutations and understanding the mutational mechanisms that act during cancer development.The neutral mutational process is very complex: whole-genome analyses have revealed that the General Electronics Books mutation rate diffe
