calmodulin/glycine max

Recently, we provided preliminary evidence for calcium (Ca2+)/calmodulin (CaM) stimulation of plant glutamate decarboxylase (GAD; EC 4.1.1.15). In the present study, a detailed characterization of the phenomenon is described. GAD was partially purified from various soybean (Glycine max L. Merr.)

The transcription of soybean (Glycine max) calmodulin isoform-4 (GmCaM-4) is dramatically induced within 0.5 h of exposure to pathogen or NaCl. Core cis-acting elements that regulate the expression of the GmCaM-4 gene in response to pathogen and salt stress were previously identified, between -1,207

It has been well demonstrated that cystatins regulated plant stress tolerance through inhibiting the cysteine proteinase activity under environmental stress. However, there was limited information about the role of cystatins in plant alkali stress response, especially in wild soybean. Here, in this

A 40-50% reduction in soybean [Glycine max (L.) Merr. cv. Century 84] hypocotyl elongation occurred 24 h after application of mechanical stress. Exogenous Ca2+ at 10 mM inhibited growth by 28% if applied with the Ca2+ ionophore A23187 to the zone of maximum hypocotyl elongation. La3+ was even more

Changes in gene expression within roots of Glycine max (soybean), cv. Kent, susceptible to infection by Heterodera glycines (the soybean cyst nematode [SCN]), at 6, 12, and 24 h, and 2, 4, 6, and 8 days post-inoculation were monitored using microarrays containing more than 6,000 cDNA inserts.

The existence of specific binding sites for a β-glucan elicitor of phytoalexin synthesis derived from the fungus Phytophthora megasperma f.sp. glycinea at the plasma membrane of soybean (Glycine max L.) tissues (W.E. Schmidt, J. Ebel (1987) Proc. Natl. Acad. Sci. USA 84, 4117-4121) might imply that

BACKGROUND Lead (Pb) and mercury (Hg) are persistent hazardous metals in industrially polluted soils which can be toxic in low quantities. Metal toxicity can cause changes at cellular and molecular level which should be studied for better understanding of tolerance mechanism in plants. Soybean

The discovery that plants contain multiple calmodulin (CaM) isoforms of variable sequence identity to animal CaM suggested an additional level of sophistication in the intracellular role of calcium regulation in plants. Past research has focused on the ability of conserved or divergent plant CaM

Ca2+ ion is a versatile second messenger that operate in a wide ranges of cellular processes that impact nearly every aspect of life. Ca2+ regulates gene expression and biotic and abiotic stress responses in organisms ranging from unicellular algae to multi-cellular higher plants through the

Plants produce numerous calmodulin isoforms that exhibit differential gene expression patterns and sense different Ca2+ signals. This diversity results in different physiological responses to particular stimuli. Gm-CaM-4 and -5 are two divergent calmodulin isoforms from the soybean (Glycine max)

In plants, powdery-mildew-resistance locus o (Mlo) genes encode proteins that are calmodulin-binding proteins involved in a variety of cellular processes. However, systematic characterization of this gene family in soybean (Glycine max L. Merr.) has not been yet reported. In this study, we

Plants express many calmodulins (CaMs) and calmodulin-like (CML) proteins that sense and transduce different Ca(2+) signals. Previously, we reported divergent soybean (Glycine max) CaM isoforms (GmCaM4/5) with differential abilities to activate CaM-dependent enzymes. To elucidate biological

A calcium-dependent protein kinase activity from suspension-cultured soybean cells (Glycine max L. Wayne) was shown to be dependent on calcium but not calmodulin. The concentrations of free calcium required for half-maximal histone H1 phosphorylation and autophosphorylation were similar (

Calmodulin (CaM) is involved in defense responses in plants. In soybean (Glycine max), transcription of calmodulin isoform 4 (GmCaM4) is rapidly induced within 30 min after pathogen stimulation, but regulation of the GmCaM4 gene in response to pathogen is poorly understood. Here, we used the yeast

Here, we compare the molecular mechanism of soybean heterosis through the differential expression of basic cloning. Specifically, we cloned 22 differentially expressed cDNA fragments from hybrid combinations of Jilin 38 x EXP (which had obvious yield advantages) and their parents. In addition, we
