The complete mitochondrial genome of the semiterrestrial crab, Chiromantes neglectum (Eubrachyura: Grapsoidea: Sesarmidae)

Abstract

The complete mitogenome of the semiterrestrial crab Chiromantes neglectum was sequenced. It contained the entire set of 37 genes. The gene order was basically identical to pancrustacean ground pattern, except for the trnH and trnQ genes. Phylogenetic inferences based on protein-coding genes (PCGs) provide strong evidence that places C. neglectum within an intermingled ‘Grapsoidea & Ocypodoidea’ clade.

Characterization of the Complete Mitochondrial Genome of the Bromeliad Crab Metopaulias depressus (Rathbun, 1896) (Crustacea: Decapoda: Brachyura: Sesarmidae)

“…Most of the PCGs and tRNA genes are encoded on the L-strand, whereas only four PCGs ( nad5 , nad4 , nad4l , and nad1 ), the two ribosomal RNA genes, and eight tRNA genes (trnH, trnF, trnP, trnL2, trnQ, trnV, trnC, and trnY) are encoded in the H-strand ( Table 1 ) ( Figure 1 ). Gene order and strand arrangement in M. depressus is identical to that reported before in all co-familiar species (except G. penangense [ 46 ]) with mitochondrial genomes deposited in GenBank (i.e., O. neglectum, O. sinense, P. bidens, and P. tripectinis , among others [ 47 , 48 , 49 , 50 ]). In contrast to the gene arrangement observed in all sesarmid crabs, with a trnQ - trnI - trnM , G. penangense exhibits a trnI - trnQ - trnM gene arrangement [ 46 ].…”

“…Compared to other decapod infraorders, brachyuran crabs (infraorder Brachyura) contain a translocation of the trnH gene between the trnE and trnF genes, rather than between the nad5 and nad4 genes [ 5 ]. This translocation is present in M. depressus and all co-familiar species [ 5 , 47 , 48 , 49 , 51 ].…”

The complete mitochondrial genome of red-clawed crab Chiromantes haematochir (Sesarmidae: Grapsidae)

“…The new sequence has higher A + T content (75.9%) and lower C + G content (24.1%), similar to other invertebrate species (Xing et al. 2016 ). Through the 13 PCGs, the longest one is ND5 (1728 bp), and the shortest is ATP8 (159 bp), similar with the other species (Xiao et al.…”

“…The length of the complete mtDNA sequence is 15 899 bp, is similar to other Chiromantes species (Xing et al 2016). It contains the typical set of 37 genes, including 13 protein-coding genes (PCGs) (ATP6, ATP8, COI-III, ND1-6, ND4L, and Cyt b), two rRNAs (12S rRNA and 16S rRNA), 22 tRNAs, and a putative CR (D-loop).…”

The highly rearranged mitochondrial genomes of the crabs Maja crispata and Maja squinado (Majidae) and gene order evolution in Brachyura

“…7 ). In fact, in addition to the taxa analysed here, SesGO has been described very recently 73 also for Sesarma neglectum , a species whose sequence became available in GenBank too late (2016-10-31) to be analysed here. At opposite, XenGO, is a very modified GO, ranking second among the most re-arranged GOs (Figs 4 and 7 ).…”
