Replication of Genetic Information with Self-Encoded Replicase in Liposomes
Hiroshi Kita,Tomoaki Matsuura,Takeshi Sunami,Kazufumi Hosoda,Norikazu Ichihashi,Koji Tsukada,Itaru Urabe,Tetsuya Yomo +7 more
TL;DR: This in‐liposome self‐encoding system is one of the simplest such systems available; it consists of only 144 gene products, while the information and the function for its replication are encoded on different molecules and are compartmentalized into the microenvironment for evolvability.
Symbiotic bacteria contribute to increasing the population size of a freshwater crustacean, Daphnia magna.
TL;DR: It is suggested that symbiotic bacteria have a beneficial effect on D. magna, and that aposymbiotic Daphnia are useful tools in understanding the role of symbioticacteria in the environmental responses and evolution of their hosts.

Rice receptor for chitin oligosaccharide elicitor does not couple to heterotrimeric G‐protein: Elicitor responses of suspension cultured rice cells from Daikoku dwarf (d1) mutants lacking a functional G‐protein α‐subunit
Koji Tsukada,Masumi Ishizaka,Yukiko Fujisawa,Yukimoto Iwasaki,Takeshi Yamaguchi,Eiichi Minami,Naoto Shibuya +6 more
TL;DR: Evidence is presented that the rice receptor for N-acetylchitooligosaccharide elicitor does not couple to heterotrimeric G-protein (G-protein), one of the most important signal transducers from the cell surface to down-stream effectors in various cellular responses of many organisms.
Kinetic Analysis of the Entire RNA Amplification Process by Qβ Replicase
TL;DR: A kinetic model that is able to account for the entire RNA amplification process is proposed and the obtained constants provide important information both for understanding the basis of Qβ phage amplification and the applications using Qβ replicase.

Importance of translation-replication balance for efficient replication by the self-encoded replicase.
Norikazu Ichihashi,Tomoaki Matsuura,Hiroshi Kita,Kazufumi Hosoda,Takeshi Sunami,Koji Tsukada,Tetsuya Yomo +6 more
TL;DR: Both the experimental and theoretical results consistently indicated that the balance between translation and replication is critical for an efficient self‐encoded system, and the optimum balance was determined.
