Nitrate Assimilation Underlying Kleptoplasty

This study identifies RvNaRL, a nitrate reductase gene acquired via horizontal gene transfer in R. viridis, which enables nitrate assimilation despite its heterotrophic lineage.

Euglenozoan kleptoplasty illuminates the early evolution of photoendosymbiosis

This study shows that the euglenozoan Rapaza viridis uses kleptoplasts from Tetraselmis sp. for temporary photosynthesis, with evidence of horizontal gene transfer and shared mechanisms with Euglenophyceae.

Quantitative analysis of calcium oxalate monohydrate and dihydrate for elucidating the formation mechanism of calcium oxalate kidney stones

This paper quantitatively analyzes calcium oxalate monohydrate and dihydrate in kidney stones using FTIR, PXRD, and micro-CT to understand their formation mechanisms.

Adenylate kinase 1 overexpression increases locomotor activity in medaka fish

This study shows that overexpressing adenylate kinase 1 in medaka fish increases locomotor activity, which is temperature-dependent.

Deep-time convergence in rove beetle symbionts of army ants

The paper shows that myrmecoid rove beetles have evolved independently multiple times, each adapting to specific army ant hosts in different regions over millions of years.

A defensive body plan was pre-adaptive for termitophily in the rove beetle tribe Termitohospitini (Staphylinidae: Aleocharinae)

This paper reconstructs the evolutionary history of termitophilous rove beetles, showing that a defensive body form was pre-adaptive for termitophily.
