Japanese cedar (Cryptomeria japonica) and Japanese cypress (Chamaecyparis obtusa) plantations account for approximately 30% of the total forested area in Japan. Both are arbuscular mycorrhizal trees that leach more NO3 in response to nitrogen (N) deposition than do forests of ectomycorrhizal trees. However, little information is available about the size of N exports from these plantations. The ...

Using the patch-clamp technique, we recorded single-channel currents across the excised patch of the plasma membrane of Nitellopsis. Both K(+) and Na(+) can pass this channel, but currents were not carried by Cl(-). Upon the addition of ATP or AMP to the cytoplasmic side, the frequency of channel opening decreased. This is the first report on an ATP-regulated channel in plant cells.

Batang kamboja (Plumeria obtusa) merupakan bagian terbesar dari tanaman yang mengandung protease sulfihidril, namun masih belum banyak dimanfaatkan. Pemanfaatan sulfihidril batang dilakukan karena memiliki aktivitas proteolisis baik. Pada penelitian ini uji agar dapat mengetahui efektivitasnya dalam menghidrolisis protein. Uji enzim ditentukan dengan metode caseein assay menggunakan kasein seba...

Broadleaf deciduous forests (BDFs) or dry dipterocarp play an important role in biodiversity conservation tropical regions. Observations and classification of forest phenology provide valuable inputs for ecosystem models regarding its responses to climate change assist management. Remotely sensed observations are often used derive the parameters corresponding seasonal vegetation dynamics. Data ...

This study was carried out to examine the action mechanism of Chamaecyparis obtusa oil (CO) on hair growth in C57BL/6 mice. For alkaline phosphatase (ALP) and γ-glutamyl transpeptidase (γ-GT) activities in the skin tissue, at week 4, the 3% minoxidil (MXD) and 3% CO treatment groups showed an ALP activity that was significantly higher by 85% (p < 0.001) and 48% (p < 0.05) and an γ-GT activity t...
