Rhizome rot caused by Pythium spp and Fusarium spp is one of the most devastating diseases of ginger in most of the ginger growing areas of the Nepal. Realizing the context for development of alternative control strategies to reduce dependency on synthetic fungicides, a field experiment on management of rhizome rot disease of ginger using eco-friendly natural products was conducted at GRP, Kapu...

The photosynthesis source-sink relationship in young Pinus canariensis seedlings was modified by stem girdling to investigate sprouting and cambial activity, feedback inhibition of photosynthesis, and stem and root hydraulic capacity. Removal of bark tissue showed a trade-off between sprouting and diameter growth. Above the girdle, growth was accelerated but the number of sprouts was almost neg...

We investigated the effect of wasabi rhizome extract on atopic dermatitis (AD) model mice. The wasabi extract was fed to the HR-1 hairless mice, which develop AD-like symptoms with a special diet (HR-AD diet). The extract was expected to reduce the symptoms induced. Wasabi rhizome-containing HR-AD diet (5% and 10%) reduced the scratching behavior, and the 10% wasabi rhizome HR-AD diet significa...

The present work carried out to establish the necessary pharmacognostic standards, according to the WHO guidelines for evaluating the plant material of Curcuma pseudomontana J. Graham rhizome. Pharmacognostic parameters such as macroscopic, microscopic, physicochemical constituents, fluorescence analysis, nutritive value, behavior analysis of rhizome powder and TLC studies were performed. Macro...

BACKGROUND The rhizome of Oni-dokoro (a wild yam, Dioscorea tokoro) has extremely bitter taste and is not generally regarded edible;, however, in northern part of Japan, such as Iwate and a part of Aomori, it is used as health promoting food. To clarify the reason, we examined the biologically active compounds in the rhizome collected at Iwate and compared them from the other area in literature...

A systematic study was conducted on P. pubescens by analyzing thermal characteristics of its rhizome and culm (1.5 m) at different ages, using various analyses such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetry (TG). For both the rhizome and culm of P. pubescens, the relative crystallinity (Cr) of cellulose increased and then appreciably decreased wit...

In arid and semi-arid sand dune ecosystems, belowground bud bank plays an important role in population regeneration vegetation restoration. However, the responses of size composition to burial its induced changes soil environmental factors have been rarely studied. dunes Northwestern China, we investigated typical rhizomatous psammophyte Psammochloa villosa as well three key (soil moisture, tot...

Neuritogenesis, the first step of neuronal differentiation, takes place as nascent neurites bud from the immediate postmitotic neuronal soma. Little is known about the mechanisms underlying the dramatic morphological changes that characterize this event. Here, we show that RhoA activity plays a decisive role during neuritogenesis of cultured hippocampal neurons by recruiting and activating its ...

To determine whether transplanted metanephroi grow and differentiate after implantation into the omentum in hosts of a different species, we implanted metanephroi from embryonic day 15 (E15) rat embryos into uninephrectomized mice (hosts). Some host mice received human CTLA4Ig (hCTLA4Ig), anti-CD45RB, and anti-CD154 (tolerance-inducing agents). E15 metanephroi contained only metanephric blastem...
