T-DNA insertion mutants reveal complex expression patterns of the aldehyde dehydrogenase 3H1 locus in Arabidopsis thaliana
The Arabidopsis thaliana aldehyde dehydrogenase 3H1 gene (ALDH3H1; AT1G44170) belongs to family 3 of the plant aldehyde dehydrogenase superfamily. The full-length transcript of the corresponding gene comprises an open reading frame of 1583 bp and encodes a protein of 484 amino acid residues. Gene expression studies have shown that this transcript accumulates mainly in the roots of 4-week-old pl...
متن کاملThe role of auxin-signaling gene axr1 in salt stress and jasmonic acid inducible gene expression in Arabidopsis thaliana
Response of auxin resistant mutant, axr1-24, on salt stress in primary root growth was tested over a range of NaCl concentrations and results were compared with wild type. The axr1-24 was more resistant to the inhibitory effect of any salt concentrations tested than wild type, except 128 mM NaCl. Total inhibition of root elongation was 62% and 70% for axr1-24 and wild type, respectively, at 64 ...
متن کاملThermospermine suppresses auxin-inducible xylem differentiation in Arabidopsis thaliana.
Thermospermine, a structural isomer of spermine, is synthesized by a thermospermine synthase designated ACAULIS5 (ACL5). Thermospermine-deficient acl5 mutant of Arabidopsis thaliana shows severe dwarfism and excessive xylem differentiation. By screening for compounds that affect xylem differentiation in the acl5 mutant, we identified auxin analogs that remarkably enhanced xylem vessel different...
متن کاملGene transcriptomic profile in arabidopsis thaliana mediated by radiation-induced bystander effects
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 کاملReal-time Analysis of Auxin Response, Cell Wall pH and Elongation in Arabidopsis thaliana Hypocotyls
The rapid auxin-triggered growth of the Arabidopsis hypocotyls involves the nuclear TIR1/AFB-Aux/IAA signaling and is accompanied by acidification of the apoplast and cell walls (Fendrych et al., 2016). Here, we describe in detail the method for analysis of the elongation and the TIR1/AFB-Aux/IAA-dependent auxin response in hypocotyl segments as well as the determination of relative values of t...
