1. Alteration in phosphate uptake potential of wheat plants co-cultivated with salicylic acid

Author:
Sahu, Gopal Krishna; Sabat, Surendra Chandra
Source:
Journal of plant physiology 2010 v.167 no.4 pp. 326-328
ISSN:
0176-1617
Subject:
Triticum aestivum; wheat; cultivars; phosphates; salicylic acid; plant hormones; uptake mechanisms; nutrient uptake
Abstract:
... The phosphate uptake potential was significantly stimulated with low concentration of salicylic acid (SA). In one of the wheat cultivars (Triticum aestivum Var. Sonalika), 50 μM SA stimulated phosphate (PO43−) uptake. At higher concentrations of SA (500 and 1000 μM), the rate of uptake was reduced. These findings underscore the light and dose-dependent biphasic action of SA: a low 50 μM stimulated ...

Abstract:
... RNAi-induced gene silencing plays a role in plant DNA methylation and defense. While most gene silencing studies have been performed on annuals, little is known about the expression of key components of this process (like ARGONAUTE proteins) in ornamentals. Using a combination of polymerase chain reaction techniques, an ARGONAUTE4 gene, PhAGO4, was isolated from Pelargonium. PhAGO4 encodes a predi ...

Abstract:
... Metabolic engineering of plant peroxisomes for biotechnological purposes typically requires efficient peroxisomal targeting of heterologous proteins. Type I peroxisomal targeting signals (PTS1) consist of three uncleaved amino acids (SKL or a conserved variant) at the carboxyl terminus and direct nuclear-encoded proteins into the peroxisomes of eukaryotic cells. PTS1 fusion with a heterologous pro ...

The data indicated that at 1 μM Cd, A. thaliana plants adapted their metabolism to cope with the Cd exposure. As a result, only moderate protein changes were observed. However, at 10 μM Cd, severe stress was indicated by growth reduction and chloro ...

Abstract:
... Arsenic (As) reduces legume nodulation by affecting the first stages of the symbiotic interaction, which causes a 90% decrease in rhizobial infections. In this paper, we examine molecular mechanisms underlying this toxic effect, using the model system Medicago sativa–Sinorhizobium. In the presence and absence of As, the expression patterns of seven nodulin genes, markers for the different events l ...
