Draft genome sequence and SSR mining data of Acacia pachyceras Schwartz

Abstract

Acacia tree population is declining in several countries of the world especially in the Arabian peninsula due to human-induced activities. The tree has potential medicinal and economic benefits as a source of fuel and timber. It can fix nitrogen, a significant property that assists in desert rehabilitation. However, the lack of genomic information of Acacia pachyceras hampers its genetic study and breeding process. We performed paired-end sequencing of A. pachyceras at a depth of 120X to obtain raw sequences of 108.9 GB with a per base quality >Q30. Filtered raw data was assembled into a fasta file of 4 GB. The assembled genomic sequences consisted of 901,755 single sequence repeats (SSRs). In total 11,596 primer pairs were designed against these SSR motifs. The data generated provides baseline genomic information about the species and formulates a base for further sequencing of A. pachyceras through PACBio and HiC technologies. The novel developed SSR markers will facilitate genetic diversity and conservation studies for Acacia species.
