Figures & Tables

Figure 1

Morphology and mitogenome structure of Cruznema tripartitum. (A, B): Head region; (C): Anterior part of body; (D): Female tail; (E): Lateral view of male tail; (F): Ventral view of male tail; (G): Mitogenome structure. The genes are denoted by the color block and encoded in the clockwise direction. The leucine and serine tRNA genes are separated by their anticodon sequences: L1 is trnL-cta, L2 is trnL-tta, S1 is trnS-aga, and S2 is trnS-tca. The region without color indicates the non-coding region.

Figure 4

Linearized mitochondrial gene arrangement patterns of Cruznema tripartitum (indicated in bold) and other related species in suborders Rhabditina and Tylenchina. All genes are encoded in the same direction. All 22 tRNA genes are designated by a single letter amino acid code, based on the International Union of Pure and Applied Chemistry code. The two leucine and two serine tRNA genes are labeled according to their distinct anticodon sequences as L1 (trnL1-cta), L2 (trnL2-tta), S1 (trnS1-aga), and S2 (trnS2-tca). The non-coding regions are not included.
