A comprehensive overview of bull sperm-borne small non-coding RNAs and their diversity across breeds

open access: yesEpigenetics & Chromatin, 2020
Background Mature sperm carry thousands of RNAs, including mRNAs, lncRNAs, tRNAs, rRNAs and sncRNAs, though their functional significance is still a matter of debate. Growing evidence suggests that sperm RNAs, especially sncRNAs, are selectively retained

Physiological breeding

open access: yesCurrent Opinion in Plant Biology, 2016
Physiological breeding crosses parents with different complex but complementary traits to achieve cumulative gene action for yield, while selecting progeny using remote sensing, possibly in combination with genomic selection. Physiological approaches have already demonstrated significant genetic gains in Australia and several developing countries of ...
