MiR396 regulatory network and its expression during grain development in wheat.

Wheat contains the largest number of miR396 family with 17 miR396 in Poaceae. MiR396 regulatory network underlying wheat grain development has not comprehensively been explored. Our results showed that precursor miR396 family in Poaceae exhibited not only conservativeness but also diversification especially in wheat.

MicroRNA-mediated responses to colchicine treatment in barley.

In Hordeum vulgare, nine differentially expressed novel miRNAs were induced by colchicine. Five novel miRNA in colchicine solution showed the opposite expression patterns as those in water. Colchicine is a commonly used agent for plant chromosome set doubling.

Nucleotide diversity patterns at the DREB1 transcriptional factor gene in the genome donor species of wheat (Triticum aestivum L).

Bread wheat (AABBDD) originated from the diploid progenitor Triticum urartu (AA), a relative of Aegilops speltoides (BB), and Ae. tauschii (DD). The DREB1 transcriptional factor plays key regulatory role in low-temperature tolerance.
