DOI: https://doi.org/10.1093/g3journal/jkab125 Interpretive Summary: This report consists of a peer-reviewed research note that describes the genome sequence assembly of the Gossypium stocksii genome. G. stocksii is a distant relative to cotton that has been surveyed for useful agronomic traits, including virus resistance to cotton leaf curl disease. Active research attempts are on-going to transfer this disease resistance to cultivated cotton. This genome sequence may increase the capacity and speed of those research efforts. Technical Abstract: Cotton is an important textile crop whose gains in production over the last century have been challenged by various diseases. Because many modern cultivars are susceptible to several pests and pathogens, breeding efforts have included attempts to introgress wild, naturally resistant germplasm into elite lines. Gossypium stocksii is a wild cotton species native to Africa, which is part of a clade of vastly understudied species. Most of what is known about this species comes from pest resistance surveys and/or breeding efforts, which suggests that G. stocksii could be a valuable reservoir of natural pest resistance. Here we present a high-quality de novo genome sequence for G. stocksii. We compare the G. stocksii genome with resequencing data from a closely related, understudied species (G. somalense) to generate insight into the relatedness of these cotton species. Finally, we discuss the utility of the G. stocksii genome for understanding pest resistance in cotton, particularly resistance to cotton leaf curl virus. |
