Molecular and Physiological Characterisation of an Insertion Mutant in the ARR21 Putative Response Regulator Gene from Arabidopsis thaliana

Popis výsledku v původním jazyce

In our search for insertion mutants of Arabidopsis response regulator (ARR) genes, we identified a candidate for an ARR21 dSpm transposon insertion line in the SLAT collection by searching the SINS sequence database. Molecular characterisation of this line revealed that the transposon is integrated as a single copy 1727 bases downstream of the ATG signal, within the third intron of the ARR21 gene. The transposon insertion segregated in a Mendelian fashion from heterozygous plants that were allowed to self-pollinate. RT-PCR-based expression analysis showed that ARR21 transcript predominantly accumulates in siliques. In contrast, the full-length ARR21 transcript was not detectable in the ARR21 transposon insertion line, indicating that it harbours an insertion of dSpm transposon in the ARR21 gene. The ARR21 insertion mutant (arr21-1) was subjected to several physiological tests for a possible insertion-linked phenotype. However, our results revealed that the insertion in the ARR21 gene d
