plant growth is a result of cell division and cell enlargement. expansins are proteins that mediate long-term extension of isolated cell walls and they play a variety of roles in plant cells. in this study the atexpb2 gene was over-expressed in arabidopsis thaliana. the gene was isolated from genomics dna of arabidopsis and cloned into mediated vectors; pgemt and pbi121 vectors. transformation ...

Plant defensins are recognized for their antifungal properties. However, a few type 1 defensins (PDF1s) were identified for their cellular zinc (Zn) tolerance properties after a study of the metal extremophile Arabidopsis halleri. In order to investigate whether different paralogues would display specialized functions, the A. halleri PDF1 family was characterized at the functional and genomic l...

SETH4 coding sequence with 2013 bp is a member of gene family expressed in gametophytic tissues of Arabidopsis thaliana. This fragment was PCR amplified using Kod Hi Fi DNA polymerase enzyme. This fragment was cloned into pGBKT7 bate vector and transformed E. coli DH5? cells containing vector were selected on LB medium containing Kanamycin. Finally, pGBKT7-SETH4 bate was transformed into yeast ...

the recently published articles in the iranian journal ofbiotechnology inspired us to write this short communication on nitrogen dioxide no2-philic plants (1).to cope with environmental pollution, we thought(still think) that development of methods that mitigatepollution is an urgent issue, and that no2-philic plantsthat can grow with no2 as the sole nitrogen source areinstrumental for the impl...

A study of spontaneous mutation in Arabidopsis thaliana was initiated from a single inbred Columbia founder; 120 lines were established and advanced 17 generations by single-seed descent. Here, we report an assay of reproductive traits in a random set of 40 lines from generations 8 and 17, grown together at the same time with plants representing generation 0. For three reproductive traits, mean...
