Karrikins are active components of smoke that can promote seed germination and regulate seedling morphogenesis. However, the role karrikins as alleviators abiotic stress remains largely elusive. In this study, we examined whether exogenous application karrikin1 (KAR1) might improve drought tolerance in creeping bentgrass (Agrostis stolonifera cv. PennA4), investigated underlying mechanism. We f...

This study compared the protective effect of cold acclimation on tolerance in lotus (Nelumbo nucifera). The increased sprouting rate and leaf expansion by about 36% at 0 °C, could enhance levels stress related osmolytes including higher proline, soluble protein, sugar contents. electrolyte leakage lipid peroxidation level control samples significantly, but these indices did not change signific...

This study aimed at investigating biological effects in Arabidopsis thaliana leaves and roots irradiated for 72 h with 3.5Gy or 30Gy of gamma radiation, and to unravel oxidative stress related responses to achieve a better understanding of the importance of the cellular redox balance as a modulator in gamma radiation stress. A. thaliana performs like a rather radioresistant plant species as no ...

The target of rapamycin (TOR) is a highly conserved protein kinase that regulates cell growth and metabolism. Here we performed a genome-wide screen to identify negative regulators of TOR complex 1 (TORC1) in Schizosaccharomyces pombe by isolating mutants that phenocopy Δtsc2, in which TORC1 signaling is known to be up-regulated. We discovered that Δnpr2 displayed similar phenotypes to Δtsc2 in...

‎In this paper‎, ‎we prove that the category of crossed polymodules (i.e‎. ‎crossed modules of polygroups) and their morphisms is finitely complete‎. ‎We‎, ‎therefore‎, ‎generalize the group theoretical case of this completeness property of crossed modules‎.
