Abstract:
... Some pri-miRNAs can code for short peptides called micropeptides (miPEPs) and it has been suggested that these peptides positively regulate the accumulation of their associated miRNAs. Recent data further support this model and point towards the potential for miPEPs to be used in the agricultural sector to improve crop agronomic traits. ...

Abstract:
... Perennial ryegrass varieties are evaluated in monoculture plots, but in practice are typically sown as combinations of three or more varieties. Monoculture performance is used a predictor of mixture performance, but is questionable, particularly for grazing efficiency traits that interact with the grazing animal. Two field experiments were carried out to examine the production, grazing efficiency ...

Abstract:
... Heading date is a key agronomic trait affecting crop yield. In rice, Early heading date 1 (Ehd1) is an important B‐type response regulator in determination of heading date. Although many regulatory factors of Ehd1 expression have been functionally characterized, the direct regulators of Ehd1 largely remain to be identified. Here, we identified a new regulator of Ehd1, OsRE1, that directly binds to ...
