Genomic data of the Apple-Ring Acacia (<i>Faidherbia albida</i>)

Faidherbia albida is an agriculturally, biologically, medicinally and economically important African orphan crop. It is a thorny tree growing up 630 m (2098 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.
<br>Here we present draft genome information of <em>Faidherbia albida.</em> The assembled genome of <em>Faidherbia albida</em> 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.

白合欢（Faidherbia albida）是一种在农业、生物学、医药及经济领域均具有重要价值的非洲孤儿作物。该树种为带刺乔木，株高可达630米（2098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性。树皮呈灰色，老龄时会出现龟裂。每千克种子约含11000粒。维基百科收录的该物种用途包括：其花对养蜂业具有重要意义；荚果可用于饲喂家畜，亦是骆驼、大象、羚羊、水牛、狒狒等多种动物的食物来源；木材灰烬可用于制作肥皂，亦可作为脱毛剂和皮革鞣制剂；木材可用于制造独木舟、臼、杵，亦可用作雕刻材料；其带刺枝条可作为天然带刺围栏使用。
本研究公开了白合欢（Faidherbia albida）的基因组草图信息。该物种的组装基因组大小为654 Mb，我们预测该作物物种共包含28979个蛋白质编码基因。我们进一步分析了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表征分析。
