The evolutionary origin of indeterminate leaves in Meliaceae: phylogenetic relationships among species in the genera Chisocheton and Guarea, as inferred from sequences of chloroplast DNA.
The aims of this study are to clarify the evolution of the controlling mechanism in the form of a simple leaf and the compound leaf of the vascular plant. We try to establish the transgenic strain using pteridophyte Asplenium australasicum. Howeve...
Our studies on mechanisms of leaf development have revealed that an unknown system integrates activities of cell proliferation and cell expansion in leaves, depending on non-cell autonomous regulations. We also showed that gene expression not only...
For clarifying the diversity of alpine plants in the Himalayas, we dispatched six botanical research teams (four to Nepal and two to China) to collect materials, and analyzed them. As a result, we have gotten many interesting findings from the fie...
We have carried out field studies in 8 islands such as Miyajima (Itsukushima), Kinkazan, Kashima, Yakushima, Tanegashma, Kuchinoerabujima, Ishigakijima, and Yonagunijima in Japan, and in five foreign islands such as Java, Bali, Borneo (Sabah and c...
The leaf is the fundamental unit of shoot morphogenesis and the leaf shepe is controlled physiologically (Nakaya et al. 2002 ; Tsukaya et al. 2002 ; 2000). We have accumulated much evidence that a decrease in the number of leaf cells can be compen...
Following the research plan proposed initially, the group of these investigators have obtained results described below. Machida isolated and characterized the ASYMMETRIC LEAVES2(AS2) and AS1 genes. Proteins that are encoded by these genes were sho...
1. Class 1 KNOX gene of Physcomitrella patens (PpKNOX 1) was cloned and each GUS and GFP reporter gene was inserted into either 3 and 5 terminal of PpKNOX genomic region using gene targeting technique. The fusion protein was expressed only in the ...
1. Field research : Field research was held in Nepal, Myanmar and China. The main purposes are to collect herbarium specimens and samples for molecular and cytological studies, and observations on reproductions and variations.(1) Nepal : Jaljale H...
Monophylly is exhibited in Monophyyllaea and in Streptocarpus (Gesneriaceae). Their plant body consists of a single large cotyledon. They never form stems or foliage leaves throughout their life history, and they produce inflorescences at the base...
We have identified the genes which related to the regulation of endoderm cell differentiation in Arabidopsis root hypocotyl and inflorescence stem. These genes are named SGR1/SCR(shoot gravitropism 1/scarecrow) and SGR7/SHR(Shoot gravitropism 7/sh...
A fluoresceinyl xyloglucan oligomer was synthesized and used as a probe to visualize the activity of the cell wall to incorporate xyloglucan fragments into the cellulose/xyloglucan framework in tabacco BY-2 cells. The activity was significantly re...
This research aimed to clarify the diversity and phylogenetic relationship of the higher plants distributed in southern margin of the Tibetan Plateau. In 1998 we surveyed the Arun River Region in eastern Nepal situated in the southernmost margin o...
This project aimed to develop a system to characterize plant genes in a large-scale. Genes involved in metabolic pathways were intensively characterized for the use in molecular breeding in agriculture. To identify a specific gene, one can purify ...
1. Various kinds of plant materials were collected from Malay Peninsula, Sarawak and Sabah, Malaysia, and Celebes, Seram (Moluccas) and Sumatra, Indonesia. Using those, the following studies were conducted.2. An analysis of molecular phylogenetic ...
The floristic connection between Himalaya and the arctic regions through the central Asiatic highland was supported by the distribution pattern and/or the presence of common or corresponding species with the arctic regions. A term "Central Asiatic...
