Comparing Trigeminal Nerve Branches in Lampreys and Gnathostomes Reveals Evolutionary Changes in Vertebrate Oral Nerve Innervation

Yuki Nakanishi, Motoki Tamura, Fumiaki Sugahara, Nono Kawada et autres

ABSTRACT The trigeminal nerve consists of three major branches or rami (r) in jawed vertebrates: the ophthalmic (rV 1 ), maxillary (rV 2 ), and mandibular (rV 3 ), with rV 2 and rV 3 innervating the upper and lower jaws, respectively. …

Embryology cannot establish the “Protura-sister”

Ryuichiro Machida, Makiko Fukui, Shigekazu Tomizuka, Yatsukaho Ikeda et autres

Du et al.( 1 ) addressed the longstanding issue of the phylogenetic relationships of the early lineages of Hexapoda, i.e., Protura, Collembola, Diplura, and Insecta (=Ectognatha).They obtained new transcriptome sequences for one proturan and two dipluran species and analyzed them, along with …

Comparative analysis of Hmx expression and the distribution of neuronal somata in the trigeminal ganglion in lamprey and shark: insights into the homology of the trigeminal nerve branches and the evolutionary origin of the vertebrate jaw

Motoki Tamura, Ryota Ishikawa, Yuki Nakanishi, Juan Pascual‐Anaya et autres

Abstract The evolutionary origin of the jaw remains one of the most enigmatic events in vertebrate evolution. The trigeminal nerve is a key component for understanding jaw evolution, as it plays a crucial role as a sensorimotor interface for the effective manipulation …

Four myriapod relatives – but who are sisters? No end to debates on relationships among the four major myriapod subgroups

Nikolaus U. Szucsich, Daniela Bartel, Alexander Blanke, Alexander Böhm et autres

BACKGROUND: Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to morphological evidence but is in conflict with most previously published phylogenetic trees based …

FGF- and SHH-based molecular signals regulate barbel and craniofacial development in catfish

Tatsuya Itoyama, Makiko Fukui, Masahumi Kawaguchi, Saki Kaneko et autres

Catfish (Siluriformes) are characterized by unique morphologies, including enlarged jaws with movable barbels and taste buds covering the entire body surface. Evolution of these characteristics was a crucial step in their adaptive radiation to freshwater environments. However, the developmental processes of the …

Detailed movement and laterality of fin-biting behaviour with special mouth morphology inGenyochromis mentoin Lake Malawi

Yuichi Takeuchi, Hiroki Hata, Atsushi Maruyama, Takuto Yamada et autres

Several vertebrates, including fish, exhibit behavioural laterality and associated morphological asymmetry. Laterality may increase individual fitness, and foraging strength, accuracy, and speed. However, little is known about which behaviours are affected by laterality or what fish species exhibit obvious laterality. Previous research …

Expression patterns of Sema3A in developing amniote limbs: With reference to the diversification of peripheral nerve innervation

Kanami Noguchi, Ryota Ishikawa, Masahumi Kawaguchi, K Miyoshi et autres

Paired limbs were acquired in the ancestor of tetrapods and their morphology has been highly diversified in amniotes in relation to the adaptive radiation to the terrestrial environment. These morphological changes may have been induced by modification of the developmental program of …

Involvement of Slit–Robo signaling in the development of the posterior commissure and concomitant swimming behavior in Xenopus laevis

Yasuhiko Tosa, Kiyohito Tsukano, Tatsuya Itoyama, Yukako Nii et autres

INTRODUCTION: During vertebrate development, the central nervous system (CNS) has stereotyped neuronal tracts (scaffolds) that include longitudinal and commissural axonal bundles, such as the medial longitudinal fascicle or the posterior commissure (PC). As these early tracts appear to guide later-developing neurons, they …
