Roots of taro (Colocasia esculenta [L.] Schott cvs Bun-long and Lehua maoli) exuded increasing concentrations of oxalate with increasing Al stress. This exudation was a specific response to excess Al and not to P deficiency. Addition of oxalate to Al-containing solutions ameliorated the toxic effect of Al.

Makomotindoline (1) was isolated from Makomotake, Zizania latifolia infected with Ustilago esculenta. The structure was determined by the interpretation of spectroscopic data and synthesis. Makomotindoline (1), its l-Glc isomer (2) and its aglycon (3) were synthesized and their effects on rat glioma cells showed adverse effects on the cell growth.

Here, we report the genome sequence of the cassava (Manihot esculenta) latex parasite Phytomonas françai P. françai infection is linked with the yield-loss disease "chochamento de raizes" (empty roots) in the Unha variety of cassava, a disease characterized by poor root development and chlorosis of the leaves.

A sharp temperature optimum is observed at 21.5 degrees C when the incorporation of [(14)C]sucrose into starch is measured with discs cut from developing tubers of potato (Solanum tuberosum L. cv Desirée). By contrast, increasing temperatures over the range 9 to 31 degrees C only enhance release of (14)C to respiratory CO(2) and incorporation of (14)C into the ethanolsoluble fraction. By compar...

Background: Candida albicans is a fungus that requires organic compounds as source of carbon and energy for growth metabolic processes obtained from carbohydrates. One the alternative media materials are readily available in nature but have not been widely utilized, namely tubers such white cassava (Manihot esculenta C.), which believed to high carbohydrate content according needs albicans.Obje...

The internal transcribed spacer (ITS) of the gene coding for rRNA was sequenced in both directions with the gene walking technique in a black morel (Morchella conica) and a yellow morel (M. esculenta) to elucidate the ITS length discrepancy between the two species groups (750-bp ITS in black morels and 1,150-bp ITS in yellow morels.

Evidence has been accumulated indicating that GnRH-like peptides are present in a variety of extrabrain areas of mammalian and nonmammalian vertebrates. A pioneer study carried out in the frog, Rana esculenta, demonstrated that testicular GnRH induced spermatogonial proliferation. Recently, we have shown that in proliferating spermatogonia (SPG) of frogs, a change of localization of the oncopro...

Abstract The Wax Lake Delta (WLD) is an actively prograding delta in the Mississippi River Plain that otherwise experiencing widespread degradation and submergence of its coastal wetlands. WLD accumulating mineral organic sediment increases soil surface elevation, changing emergent wetland communities as young develops. There uncertainty how dynamics community composition respond to net changes...

Road traffic and the loss of forests are both known to have negative effects on anurans. However, the relative importance of these two predictors is poorly understood because forest cover in the landscape is usually negatively correlated with the density of roads and traffic. To evaluate the independent effects of traffic and forest cover, we selected 36 ponds near Ottawa, Canada, at the center...
