An object of the present invention is to provide a plant transformation method that is convenient and is widely applicable to various types of plant cells and nucleic acids. The present invention relates to a method for transforming a target plant, comprising the steps of:a) contacting a carrier peptide comprising a cell-penetrating sequence and a polycation sequence with a nucleic acid to form a complex; b) contacting the obtained complex with a cell of a meristem of the target plant to transfer the nucleic acid to the genome; c) allowing the meristem to grow; and d) selecting a plant harboring the transferred nucleic acid.

The present invention is intended to provide a novel fluorescent labeled single-stranded nucleic acid, by which the background of an exciton oligomer can be further reduced and the novel use thereof. The present invention relates to a labeled single-stranded nucleic acid having at least two fluorescent atomic group pairs that exhibit an exciton effect. The labeled single-stranded nucleic acid is characterized in that the emission peak wavelength of one of the fluorescent atomic group pairs (fluorescent atomic group pair A) is shorter than the excitation peak wavelength of the other fluorescent atomic group pair (fluorescent atomic group pair B), and the fluorescent atomic group pairs A and B have a Forster resonance energy transfer (FRET) effect. This fluorescent labeled single-stranded nucleic acid is usable as a primer for amplifying a target nucleic acid or a probe to be hybridized with a target nucleic acid.

Epithelial cells display dynamic behaviours, such as rearrangement, movement and shape changes, particularly during embryonic development and in equivalent processes in adults. Accumulating evidence suggests that the remodelling of cell junctions, especially adherens junctions (AJs), has major roles in controlling these behaviours. AJs comprise cadherin adhesion receptors and cytoplasmic proteins that associate with them, including catenins and actin filaments, and exhibit various forms, such as linear or punctate. Remodelling of AJs induces epithelial reshaping in various ways, including by planar-polarized apical constriction that is driven by the contraction of AJ-associated actomyosin and that occurs during neural plate bending and germband extension. RHO GTPases and their effectors regulate actin polymerization and actomyosin contraction at AJs during the epithelial reshaping processes. copyright © 2014 Macmillan Publishers Limited.
