Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha

Go Sasaki, Keisuke Ishiwata, Ryuichiro Machida, Takashi Miyata et autres

BACKGROUND: Molecular phylogenetic analyses have revealed that Hexapoda and Crustacea form a common clade (the Pancrustacea), which is now widely accepted among zoologists; however, the origin of Hexapoda remains unresolved. The main problems are the unclear relationships among the basal hexapod lineages, …

Ancient divergence of animal protein tyrosine kinase genes demonstrated by a gene family tree including choanoflagellate genes

Hiroshi Suga, Go Sasaki, Kei‐ichi Kuma, Hiromi Nishiyori et autres

Animal-specific gene families involved in cell-cell communication and developmental control comprise many subfamilies with distinct domain structures and functions. They diverged by subfamily-generating duplications and domain shufflings before the parazoan-eumetazoan split. Here, we have cloned 40 PTK cDNAs from choanoflagellates, Monosiga ovata, …

Molecular characterization of water-selective AQP (EbAQP4) in hagfish: insight into ancestral origin of AQP4

Goro Nishimoto, Go Sasaki, Eishin Yaoita, Masaaki Nameta et autres

Hagfish (Eptatretus burgeri) are agnathous and are the earliest vertebrates still in existence. Pavement cells adjacent to the mitochondria-rich cells show orthogonal arrays of particles (OAPs) in the gill of hagfish, a known ultrastructural morphology of aquaporin (AQP) in mammalian freeze-replica studies, …
