Effects of cerium and lanthanum on Arabidopsis thaliana
ثبت نشده
چکیده
The effects of cerium and lanthanum on the vegetative and reproductive growth of Arabidopsis thaliana were investigated. Addition of cerium (III) nitrate (0.5-50μM) and/or lanthanum nitrate (0.5-50μM) to the culture medium and the potting mix showed varied results. Pot trials were done with uniform conditions for light, water and temperature. Factors examined include root length, height, number of leaves and dry weight. Results were inconsistent due to various factors such as environment and methods. Overall, it shows that the use of REEs does have an effect on the growth of Arabidopsis thaliana, whether inhibitory or beneficiary. The various problems faced with such a study are described.

Background: The in vivo radiation-induced bystander effects (RIBE) at the developmental, genetic, and epigenetic levels have been well demonstrated using model plant Arabidopsis thaliana (A. thaliana). However, the mechanisms underlying RIBE in plants are not clear, especially lacking a comprehensive knowledge about the genes and biological pathways involved in the RIBE in plants. Materials and...
متن کاملNegative control of Strictisidine synthase like-7 gene on salt stress resistance in Arabidopsis thaliana
Strictosidine synthase-like (SSL) is a group of gene families in the Arabidopsis genome, which whose orthologues in other plants are key enzymes in mono-terpenoid indole-alkaloid biosynthesis pathway. The SSL7 is upregulated upon treatments of Arabidopsis plants with signaling molecules such as SA, methyl jasmonate and ethylene. To find the functional role of the gene, a T-DNA-mediated knockout...
متن کاملFunctional analysis of glycin rich- RNA binding protein, a suppressor of trehalose-6-phosphate mediating growth arrest in Arabidopsis thaliana
Metabolism of the alpha-1,1 glucose disaccharide, trehalose, is indispensable in plants. In the Murashigeand Skoog (MS) medium, trehalose inhibits plant growth and allocation of carbon to roots. A suppressorof trehalose-6-phosphate (T6P) mediated growth arrest, GR-RBP2, is characterized in more detail.Phylogenetic analysis revealed that GR-RBP2 is a protein of likely prokaryot...
متن کاملDifferential Expression of Arabidopsis thaliana Acid Phosphatases in Response to Abiotic Stresses
The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...
