| Description | DH-Pahang (doi:10.18730/9MZSP) is a doubled-haploid of the germplasm collection accession named Pahang (doi:10.18730/9K93B). Pahang was collected in Malaysia’s Pahang province in the late 1940s. It is a wild accession that belongs to subspecies Musa acuminata ssp. malaccensis, whose genetic signature is commonly found in dessert and cooking bananas. DH stands for Doubled Haploid which refers to the induced doubling of the chromosomes in a haploid cell (which has one set of chromosomes). In this case, the haploid cell was pollen. The doubled-haploid (DH Pahang) was produced through anther culture and spontaneous chromosomes doubling. The Musa acuminata reference genome sequence results from collaboration between Genoscope and CIRAD (UMR AGAP) funded by ANR. The sequence was analyzed in collaboration with several teams within the Global Musa Genomics Consortium (GMGC). It was published in version 1: D’Hont A, Denoeud F, Aury JM., Baurens FC, Carreel F, Garsmeur O, Noel B, Bocs S, Droc G, Rouard M, et al. (2012) The banana (Musa acuminata) genome and the evolution of monocotyledonous plants. Nature, 10.1038/nature11241.
The reference sequence was then improved by a combination of methods and datasets, leading the release of the version 2 of the assembly and gene annotation, which are described in the following publication: Martin G, Baurens FC, Droc G, Rouard M, Cenci A, Kilian A, Hastie A, Dolezel J, Aury JM, Alberti A, Carreel F, D’Hont A (2016) Improvement of the banana “Musa acuminata” reference sequence using NGS data and semi-automated bioinformatic methods. BMC Genomics.
The latest version corresponds to the version 4 (version 3 was skipped) described in
Belser, C., Baurens, F.-C., Noel, B., Martin, G., Cruaud, C., Istace, B., Yahiaoui, N., Labadie, K., Hřibová, E., Doležel, J., et al. (2021). Telomere-to-telomere gapless chromosomes of banana using nanopore sequencing. BioRxiv 2021.04.16.440017.
