Bioactivity-directed fractionation of the fermentation broth and mycelium of the coprophilous fungus Guanomyces polythrix led to the isolation of several phytotoxic compounds, including five new naphthopyranone derivatives (1-5). In addition, rubrofusarin B, emodin, citrinin, and 4-hydroxybenzoic acid methyl ester were obtained. The structures of the new compounds were established by spectral a...
Fructose-6-phosphate,2-kinase and fructose-2,6-bisphosphatase were separated on the basis of charge from leaves of C3 (spinach, lettuce, and pea) and C4 (sorghum and amaranthus) plants but not from rat liver--a tissue known to contain a bifunctional enzyme with both activities. [2-32P]Fructose 2,6-bisphosphate binding experiments also suggest that the major forms of these activities reside on ...
The rate o f photosynthesis in intact leaves o f a triazine-resistant biotype o f Amaranthus retroflexus was about 15% lower than that o f a triazine-susceptible biotype. Differences in photosyn thesis between resistant and susceptible biotypes o f Polygonum lapathifolium, Poa annua and Solanum nigrum were not significant, and absent in Chenopodium album and Stellaria media. The results are br...
The field of coordination polymers and metal–organic frameworks (MOFs) has evolved over a period of approximately 25 years to a stage where it is one of the most widely investigated areas of materials chemistry. The field has impacted many areas of science including commercial applications from gas storage agents to new investigations as drug-delivery vehicles [1]. Coordination polymers and MOF...
The effect of temperature (35, 50, and 60°C) on the rehydration behavior of microwave-dried amaranth (Amaranthus dubius) leaves was investigated. Leaves were dried at 700 W power level before rehydrating in water. The higher the rehydration temperature, the higher the equilibrium moisture content of the leaves, although the effect was not statistically significant. The increase in rehydration r...
بهمنظور ارزیابی اثرات دگرآسیبی غلظتهای مختلف (شاهد، 5/2، 5، 5/7 و 10 درصد) از آبشویهی تاج خروس وحشی (amaranthus retroflexus l.) بر جوانهزنی و رشد دانهرستهای گندم (triticum aestivum l. cv. pishgham)، آزمایشی در قالب یک طرح کاملا تصادفی با سه تکرار انجام گردید. تاخیر در جوانهزنی گندم، کاهش درصد و نیز سرعت جوانهزنی در تیمار با آبشویهی تاج خروس وحشی مشاهده شد. شاخصهای رشدی دانهرستهای گن...
