Yellow rust is one of the most destructive diseases for winter wheat and has led to a significant decrease in winter wheat quality and yield. Identifying and monitoring yellow rust is of great importance for guiding agricultural production over large areas. Compared with traditional crop disease discrimination methods, remote sensing technology has proven to be a useful tool for accomplishing s...

Switchgrass (Panicum virgatum) is a perennial C 4 grass native to the central prairies of North America. Recent development of switchgrass as a sustainable biofuel feedstock has raised interest in diseases that could impact switchgrass, especially when grown under monoculture conditions. Among the known diseases of switchgrass, rust diseases are the most widespread and could potentially impact ...

Digital image processing has been applied to diverse industry disciplines. The wide application of digital image processing can be attributed to the following advantages: accuracy, objectivity, fastness, consistency, and the mixture of them. Although the RUst Defect Assessment(RUDA) method [1] was efficiently used to differentiate defective images from non-defective images on blue color coat, i...

Arginine synthesis and urea formation via the ornithine cycle occurred in sporophore cap and stipe of Coprinus cinereus. Although urease was found at high activity in mycelium and stipe, it was not detectable in extracts of cap tissue, but arginine biosynthesis was specifically amplified during development of the cap as judged from metabolism of isotopically labelled substrates and increased en...

The two patients with remaining rust and symptoms had the rust surgically removed and became symptom-free. In the last group, one patient complained of continued irritation in the eye for which no cause could be found. The other two patients developed corneal ulceration in the area of the original foreign body; although at this time there was no remaining rust, there was a heavy flare and cells...

Lentinus crinitus is a wild fungus, which produces mushrooms consumed by some Amazonian Indians. Besides, it recognized for its diverse biological activities and biotechnological applications. However, there are few reports with limited information on basidiocarp chemical composition cytotoxicity. Our study determined evaluated the composition, cytotoxicity, antioxidant activity of L. pileus st...

RL6137, a ‘Thatcher’ backcross line of wheat (Triticum aestivum L.) has resistance to Puccinia triticina (causal agent of wheat leaf rust) derived from T. monococcum. To determine the chromosome location of this resistance, RL6137 was crossed with Thatcher and F2 individual seedlings were tested for segregation of leaf rust resistance and segregation of polymorphic simple sequence repeat (SSR) ...

Stable resistance to infection with Wheat streak mosaic virus (WSMV) can be evolved de novo in selfing bread wheat lines subjected to cycles of WSMV inoculation and selection of best-performing plants or tillers. To learn whether this phenomenon might be applied to evolve resistance de novo to pathogens unrelated to WSMV, we examined the responses to leaf rust of succeeding generations of the r...

Proteins in intercellular washing fluid (IWF) from wheat (Triticum aestivum) and barley (Hordeum vulgare) leaves were separated by two-dimensional isoelectric focusing-polyacrylamide gel electrophoresis and stained with Coomassie brilliant blue (CBB) or silver. Intracellular protein from the cut ends of leaves accounted for only a small proportion of total protein in IWF from wheat leaves. When...

Several weathering steels and a plain carbon steel exposed to atmosphere for 17 years at Yokkaichi (at a coastal and industrial region) and Mikuni Pass (at a rural region) in Japan were analyzed and compared to find effects of environments on the formed rusts. Specimens were examined with electron probe microanalysis (EPMA), X-ray diffraction (XRD) and transmission electron microscope (TEM). Th...
