Phosphate-induced-1 gene from Eucalyptus (EgPHI-1) enhances osmotic stress tolerance in transgenic tobacco

A. O. Sousa, Assis, E. T. C. M., Pirovani, C. P., Alvim, F. C., and Costa, M. G. C., Phosphate-induced-1 gene from Eucalyptus (EgPHI-1) enhances osmotic stress tolerance in transgenic tobacco, vol. 13, pp. 1579-1588, 2014.

Environmental stresses such as drought, freezing, and high salinity induce osmotic stress in plant cells. The plant response to osmotic stress involves a number of physiological and developmental changes, which are made possible, in part, by the modulation of the expression of specific genes.

Alternaric acid stimulates phosphorylation of His-tagged RiCDPK2, a calcium-dependent protein kinase in potato plants

A. Hassan, Okuta, T., Kato, M., Hatsugai, N., Sano, Y., Ishimori, T., Okazaki, K., Doullah, M. A., and Shah, M. M., Alternaric acid stimulates phosphorylation of His-tagged RiCDPK2, a calcium-dependent protein kinase in potato plants, vol. 11, pp. 2381-2389, 2012.

Calcium-dependent protein kinases (CDPK) are an essential component of plant defense mechanisms against pathogens. We investigated the effect of alternaric acid, a host-specific toxin produced by the plant fungal pathogen Alternaria solani (Pleosporaceae), on a putative plasma membrane and cytosolic kinase RiCDPK2 of potato (Solanum tuberosum) and on hypersensitive cell death of host potato cells.

Activation of proacrosin accompanies upregulation of sp32 protein tyrosine phosphorylation in pig sperm

P. L. Sun, Yang, L. X., Cui, J. - J., Tian, Y., Liu, Y., and Jin, Y., Activation of proacrosin accompanies upregulation of sp32 protein tyrosine phosphorylation in pig sperm, vol. 12, pp. 6579-6587, 2013.

This study investigated the relationship between acrosin activation and pig sperm proacrosin binding protein (sp32) phosphorylation levels. Differently processed pig spermatozoa (fresh semen sperm, capacitation sperm, acrosome reaction sperm, capacitation-like sperm, and thawed sperm) were subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis and Western blot analysis.
