[Hydridotris(pyrazol-1-yl-κN(2))borato]bis-(methyl-amino-κN)(triphenyl-phos-phine-κP)ruthenium(II) chloride dichloro-methane solvate monohydrate.

The title salt, [Ru(Tp)(CH(5)N)(2)(PPh(3))]Cl·CH(2)Cl(2)·H(2)O [where Tp is (C(3)H(3)N(2))(3)BH and PPH(3) is C(18)H(15)P], has the Ru(III) atom in an octa-hedral geometry; one of the Ru-N(Tp) bonds [2.135 (8) Å] is slightly longer than another two, owing to the trans influence of PPh(3) ligand. N-H⋯Cl and O-H⋯Cl hydrogen bonding leads to the formation of layers parallel to (100).

Cloning and characterization of a calcium dependent protein kinase gene associated with cotton fiber development.

The gene GhCPK1 encoding a calcium dependent protein kinase was identified from cotton. Transcripts of GhCPK1 accumulated primarily in the elongating fiber, and Arabidopsis plants transformed with GhCPK1 promoter-GUS construct exhibited GUS activity mainly in the developing trichomes, roots, young leaves and sepals. In the bombarded onion epidermal cells, GhCPK1-GFP fusion proteins showed a subcellular distribution in the plasma membrane. In vitro assays indicated that GhCPK1 was a functional calcium-dependent kinase able to undergo autophosphorylation and phosphorylation of the known substrate histone III-S. Together, these results suggest that GhCPK1 may play a role in the calcium signaling events associated with fiber elongation.
