Molecular cloning and characterisation of SlAGO family in tomato.

ABSTRACT:

Background

AGO (Argonaute) protein participates in plant developmental processes and virus defense as a core element of transcriptional regulator or/and post-transcriptional regulator in RNA induced silencing complex (RISC), which is guided by small RNAs to repress target genes expression. Previously, it was revealed that 15 putative AGO genes in tomato genome.

Results

In present study, out of 15 detected SlAGO genes, only SlAGO4C and SlAGO15 couldn't be detected in roots, stems, leaves, buds, flowers and fruit of tomato by 30 cycles of PCR. SlAGO7 could be detected in early stage of fruit (-2 dpa, 0 dpa and 4 dpa), but it was significantly down-regulated in fruit collected on the 6 days post anthesis. Moreover, SlAGO5 could only be detected in reproductive tissues and SlAGO
