Arabidopsis SGS2 and SGS3 genes are required for posttranscriptional gene silencing and natural virus resistance

Article Abstract:

Research has been conducted on the posttranscriptional gene silencing (PTGS) in plants. The isolation of the Arabidopsis mutants impaired in PTGS has been performed.

An RNA-dependent RNA polymerase gene in Arabidopsis is required for posttranscriptional gene silencing mediated by a transgene but not by a virus

Article Abstract:

Research has been conducted on the posttranscriptional gene silencing. Four genetic loci required for this gene silencing have been investigated.

The SHORT-ROOT gene controls radial patterning of the Arabidopsis root through signaling

Article Abstract:

Research has been conducted on the asymmetric cell division. The experiments with the SHORT-ROOT gene that encodes a putative transcription factor with homology to SCARECROW are discussed.
