The barley pan-genome reveals the hidden legacy of mutation breeding

Jayakodi, Padmarasu et al. (2020) DOI: 10.1038/s41586-020-2947-8

This paper in Nature describes the DNA sequencing and analysis of the genomes of 20 diverse barley genotypes, a pan-genome.  Surprisingly, the number of genes and the arrangement and orientation of large parts of individual chromosomes differed in the individual genomes, which will present barriers to combining desirable characters by traditional plant breeding.

Communications Biology

Overcoming barriers to the registration of new plant varieties under the DUS system

Yang, C.J., Russell, J., Ramsay, L. et al. (2021) DOI: 10.1038/s42003-021-01840-9

Distinctness, Uniformity and Stability (DUS) is an intellectual property system introduced in 1961 by the International Union for the Protection of New Varieties of Plants (UPOV) for safeguarding the investment and rewarding innovation in developing new plant varieties. Despite the rapid advancement in our understanding of crop biology over the past 60 years, the DUS system has changed little and is still largely dependent upon a set of morphological traits for testing candidate varieties.

APETALA2 functions as a temporal factor together with BLADE-ON-PETIOLE2 and MADS29 to control flower and grain development in barley

Shoesmith JR et al. (2021) DOI: 10.1242/dev.194894

Using advanced molecular tools and gene-editing techniques, our team showed that HvAP2 regulates multiple events during floret and grain development, including the formation of floret hulls which protect grain and the development of the calorie-rich starchy endosperm within grain.
