Small RNAs serve as a genetic buffer against genomic shock in Arabidopsis interspecific hybrids and allopolyploids

Creator:

Ha, Misook, Lu, Jie, Ramachandran, Vanitharani, Kasschau, Krisitin D., Chapman, Elisabeth J., Carrington, James C., Chen, Xuemei, Wang, Xue-Jei, and Chen, Z. Jeffrey

Abstract:

Small RNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs), and trans-acting siRNAs (tasiRNAs), control gene expression and epigenetic regulation. Although the roles of miRNAs and siRNAs have been extensively studied, their expression diversity and evolution in closely related species and interspecific hybrids are poorly understood. Here, we show comprehensive analyses...

Identification of MIR390a precursor processing defective mutants in Arabidopsis by direct genome sequencing

Creator:

Cuperus, Josh T., Montgomery, Taiowa A., Fahlgren, Noah, Burke, Russell T., Townsend, Tiffany, Sullivan, Christopher M., and Carrington, James C.

Abstract:

Transacting siRNA (tasiRNA) biogenesis in Arabidopsis is initiated by microRNA (miRNA) –guided cleavage of primary transcripts. In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)– miR390 complexes interact with primary transcripts at two sites, resulting in recruitment of RNA-DEPENDENT RNA POLYMERASE6 for dsRNA biosynthesis. An extensive screen for Arabidopsis mutants...
