Multicellular organisms rely on intercellular communication systems to organize their cellular functions. In studies focusing on intercellular communication, the key experimental techniques include the generation of chimeric tissue using transgenic...

Female gametophyte (FG) is crucial for reproduction in flowering plants. Arabidopsis thaliana produces Polygonum-type FGs, which consist of an egg cell, two synergid cells, three antipodal cells and a central...

Interactions between heat shock (HS) factors (HSFs) and heat shock response elements (HSEs) are important during the heat shock response (HSR) of flora and fauna. Moreover, plant HSFs that are...

The liverwort Marchantia polymorpha is an emerging model plant suitable for addressing, using genetic approaches, various evolutionary questions in the land plant lineage. Haploid dominancy in its life cycle facilitates...

Heat shock promoters are powerful tools for the precise control of exogenous gene induction in living organisms. In addition to the temporal control of gene expression, the analysis of gene...

In plant meristems, each cell divides and differentiates in a spatially and temporally regulated manner, and continuous organogenesis occurs using cells derived from the meristem. We report the identification of...

Modification of genes through homologous recombination, termed gene targeting, is the most direct method to characterize gene function. In higher plants, however, the method is far from a common practice....
