Cloning and characterization of two Argonaute genes in wheat (Triticum aestivum L.).

ABSTRACT:

Background

Argonaute proteins are key components of RNA interference (RNAi), playing important roles in RNA-directed gene silencing. Various classes of Argonaute genes have been identified from plants and might be involved in developmental regulation. However, little is known about these genes in wheat (Triticum aestivum).

Results

In this study, two full-length cDNAs of Argonaute were cloned from wheat, designated as TaAGO1b and TaAGO4. The cDNA of TaAGO1b is 3273 bp long and encodes 868 amino acids, with a predicted molecular weight of ~97.78 kDa and pI of 9.29. The 3157-bp TaAGO4 encodes 916 amino acids, with a molecular mass of 102.10 kDa and pI of 9.12. Genomics analysis showed that TaAGO1b and TaAGO4 contain 20 and 18 introns, respectively.
