Nosema sp. YNPr (Fig. 1B) was isolated from cabbage butterfly Pieris rapae (Fig. 1A), an economic pest of cruciferous crops, such as cabbage, rape, cauliflower and broccoli. Phylogentic analysis shows a closer relationship between Nosema sp. YNPr and Nosema ceranae than between Nosema ceranae and Nosema apis (both honeybee parasites) (Fig. 2). The genome of Nosema sp. YNPr was sequenced by Illumina sequencing. The genome of Nosema sp. YNPr is 3.36 Mbp with a G+C content of 23.18% and 2,075 protein coding sequences [1].
