It was in 1936 when the existence of ‘florigen’ was initially predicted as a plant hormone that transmits information on daylight length at their leaves to the tip of the stem and stimulates flower initiation. In 2007, it was finally identified as a protein, which is coded by the FT gene in Arabidopsis thaliana. FT protein is produced in the leaves and transmitted to the growing tip at the shoot apical meristem via the phloem, and interacts with a transcription factor (the product of the FD gene in Arabidopsis) to induce genes involved in flower initiation. In this drawing, an actor performing FT is contacting another actor performing FD, and trying to stimulate flower initiation with him in front of hydrangea flowers that represent the month of June in Japan.

Abstract

Genome editing technologies have been invented and improved in recent years, and there is a growing expectation that the technologies can be utilized as a tool not only for molecular biological studies, but also for genetic therapies. Among them, CRISPR‐Cas9 system that was originally found as a part of the bacterial adaptive immune system gets noticed for its easy introduction. Here, users are only required to design a guide RNA with a 20‐nt sequence that is complementary to the target DNA sequence and co‐express Cas9 with the RNA in vivo, then Cas9 protein will cleave the target DNA in a site‐specific manner. This is a portrait of a kabuki actor who plays Cas9 as indicated by the crest “ku” (‘nine’) on kimono he is wearing. The “actor” definitely has a promising future ahead of him.

The normal white (w+) gene in Drosophila is required for production of red pigment in the eyes. In some mutants in which the w+ gene has been moved to a region near the centrosomal heterochromatin due to an inversion in the X chromosome, the eyes are mottled with red and white patches; the w+ gene in the white cells has been silenced due to spreading heterochromatin, while w+ gene in the red cells is active. This phenomenon is called PEV (position‐effect variegation), and a number of factors that control epigenetics, such as histone methyltransferases, have been identified by measuring the extent of variegation. Now, in this sliding screen, maple leaves in autumn were drawn with Japanese ink on gold foil background except some in the central oval with a red paint as an accent. A shadow that looks like Drosophila happened to be cast on it, emerging a figure of the w mutant with a mottled eye. Designed by TRAIS Co., Ltd. (Kobe, Japan)
