Expression of Osmotin-Like Genes in the Halophyte Atriplex nummularia L.
A peptide (molecular mass 50 kilodaltons) that is immunologically related to tobacco osmotin was detected in cells of the halophyte Atriplex nummularia. This protein was constitutively expressed in both unadapted and NaCl-adapted cells. A predominant osmotin-like peptide (molecular mass 24 kilodaltons) was also found in culture media after cell growth. Two unique A. nummularia cDNA clones, pA8 ...
متن کاملSimilar regulation patterns of choline monooxygenase, phosphoethanolamine N-methyltransferase and S-adenosyl-L-methionine synthetase in leaves of the halophyte Atriplex nummularia L.
Glycinebetaine (betaine) highly accumulates as a compatible solute in certain plants and has been considered to play a role in the protection from salt stress. The betaine biosynthesis pathway of betaine-accumulating plants involves choline monooxygenase (CMO) as the key enzyme and phosphoethanolamine N-methyltransferase (PEAMT), which require S-adenosyl-L-methionine (SAM) as a methyl donor. SA...
متن کاملExpression of an Atriplex nummularia gene encoding a protein homologous to the bacterial molecular chaperone DnaJ.
DnaJ is a 36-kD heat shock protein that functions together with Dnak (Hsp70) as a molecular chaperone in Escherichia coli. We have obtained a cDNA clone from the higher plant Atriplex nummularia that encodes a 46.6-kD polypeptide (ANJ1) with an overall 35.2% amino acid sequence identity with the E. coli DnaJ. ANJ1 has 43.4% overall sequence identity with the Saccharomyces cerevisiae cytoplasmic...
متن کاملPlant responses to heterogeneous salinity: growth of the halophyte Atriplex nummularia is determined by the root-weighted mean salinity of the root zone
Soil salinity is generally spatially heterogeneous, but our understanding of halophyte physiology under such conditions is limited. The growth and physiology of the dicotyledonous halophyte Atriplex nummularia was evaluated in split-root experiments to test whether growth is determined by: (i) the lowest; (ii) the highest; or (iii) the mean salinity of the root zone. In two experiments, plants ...
متن کاملAn Atriplex nummularia cDNA with Sequence Relatedness to the Algal Caltractin Gene.
Calcium controls numerous cellular processes with a high degree of spatial and temporal precision. One way by which these controls are effected is through the transduction of a Ca2" signal by an interaction of the cation with Ca2"-binding proteins. Among the Ca2"-binding proteins that are presumed to function in the modulation of cellular processes are calmodulin, troponin C, myosin light chain...
