Genomic data of the Apple-Ring Acacia (Faidherbia albida)

Faidherbia albida is an agriculturally, biologically, medicinally and economically important African orphan crop. It is a thorny tree growing up 6–30 m (20–98 ft) tall and 2 m (6.6 ft) in trunk diameter. Its deep-penetrating tap root makes it highly resistant to drought. The bark is grey, and fissured when old. There are 11,000 seeds/kg. Wikipedia includes in its list of uses; flowers are important in raising bees; seed pods important for raising livestock and as food sources for camel, elephant, antelope, buffalo, baboons and others; Ashes of the wood are used in making soap and as a depilatory and tanning agent for hides; Wood is used for canoes, mortars, and pestles, and carving; the thorny branches useful for a natural barbed fence. Here we present draft genome information of Faidherbia albida. The assembled genome of Faidherbia albida is 654 Mb, and we predict 28979 protein-coding genes for this crop species. We have further analyzed the expansion and contraction of selected gene families, and characterized root-nodule-symbiosis genes, transcription factors and starch biosynthesis related genes in the genome of this species.

Faidherbia albida是一种兼具农业、生物学、医药与经济价值的非洲孤儿作物（orphan crop）。该物种为带刺乔木，株高可达6–30米（20–98英尺），树干直径可达2米（6.6英尺）。其深扎的主根使其具备极强的耐旱能力。树皮呈灰色，老龄时会出现龟裂。每千克种子约含11000粒。维基百科收录了该物种的多项用途：其花是饲养蜜蜂的重要蜜源；荚果可用于饲喂家畜，同时也是骆驼、大象、羚羊、水牛、狒狒等多种野生动物的食物来源；木材灰烬可用于制备肥皂，亦可作为脱毛剂与皮革鞣制剂；木材可用于制造独木舟、臼、杵，亦可用于雕刻；其带刺枝条可作为天然带刺围栏使用。本研究报道了Faidherbia albida的基因组草图信息。该物种的组装基因组大小为654 Mb，研究团队预测其包含28979个蛋白质编码基因。本研究进一步分析了部分选定基因家族的扩张与收缩情况，并对该物种基因组中的根瘤共生基因、转录因子以及淀粉生物合成相关基因进行了特征解析。
