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...

manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. myc2 gene encodes a key stress-related transcription factor involved in jasmonate (ja) and abscisic acid (aba) signaling pathways in arabidopsis. brassica napus, as a globally important oilseed crop, is a close relative of arabidopsis.  in the present study...

AthaMap generates a map for cis-regulatory sequences for the whole Arabidopsis thaliana genome. AthaMap was initially developed by matrix-based detection of putative transcription factor binding sites (TFBS) mostly determined from random binding site selection experiments. Now, also experimentally verified TFBS have been included for 48 different Arabidopsis thaliana transcription factors (TF)....

Nucleolar dominance is an epigenetic phenomenon in which one parental set of ribosomal RNA (rRNA) genes is silenced in an interspecific hybrid. In natural Arabidopsis suecica, an allotetraploid (amphidiploid) hybrid of Arabidopsis thaliana and Cardaminopsis arenosa, the A. thaliana rRNA genes are repressed. Interestingly, A. thaliana rRNA gene silencing is variable in synthetic Arabidopsis suec...

The protein family of anion channel (ClC) constitute a family of transmembrane trnsporters that either function as anion channel or as H+/anion exchanger. The expression of three genes of AtClCa, AtClCb and AtClCd in the model plant Arabidopsis thaliana were silenced by a T-DNA insertion . When the pH of the medium was slightly acidic the length of the primary root of plants with a disrupted At...

Leaf senescence constitutes the last stage of leaf development in plants and proceeds through a highly regulated program in order to redistribution of micro- and macro-nutrients from the senescing leaves to the developing/growing plant organs. Initiation and progression of leaf senescence is accompanied by massive sequential alterations at various levels of leaf biology including leaf morpholog...

A GENOME-WIDE ANALYSIS OF PERFECT INVERTED REPEATS IN ARABIDOPSIS THALIANA by Sutharzan Sreeskandarajan Perfect inverted repeats play wide variety of roles in genomes. In this study, we conduct a genome-wide analysis of perfect inverted repeats in Arabidopsis thaliana and explore the biological significance of the observed inverted repeat distribution. The roles of palindromic sequences are rev...
