Two closely related ophiostomatoid fungi, Knoxdaviesia capensis and K. proteae, inhabit the fruiting structures of certain Protea species indigenous to southern Africa. Although K. capensis occurs in several Protea hosts, K. proteae is confined to P. repens. In this study, the genomes of K. capensis CBS139037 and K. proteae CBS140089 are determined. The genome of K. capensis consists of 35,537,816 bp assembled into 29 scaffolds and 7940 predicted protein-coding genes of which 6192 (77.98 %) could be functionally classified. K. proteae has a similar genome size of 35,489,142 bp that is comprised of 133 scaffolds. A total of 8173 protein-coding genes were predicted for K. proteae and 6093 (74.55 %) of these have functional annotations. The GC-content of both genomes is 52.8 %.
两种亲缘关系密切的长喙壳类真菌，即卡普敦诺克斯盘菌（Knoxdaviesia capensis）和山龙眼诺克斯盘菌（K. proteae），寄生于非洲南部本土某些山龙眼科植物的子实体结构中。虽然卡普敦诺克斯盘菌存在于多种山龙眼科寄主植物中，但山龙眼诺克斯盘菌仅局限于丛生山龙眼（Protea repens）。在本研究中，测定了卡普敦诺克斯盘菌CBS139037和山龙眼诺克斯盘菌CBS140089的基因组。卡普敦诺克斯盘菌的基因组由35,537,816个碱基对组成，组装成29个支架，预测有7940个蛋白质编码基因，其中6192个（77.98%）可进行功能分类。山龙眼诺克斯盘菌的基因组大小与之相似，为35,489,142个碱基对，由133个支架组成。山龙眼诺克斯盘菌共预测有8173个蛋白质编码基因，其中6093个（74.55%）具有功能注释。两种基因组的GC含量均为52.8%。
