Background Weeds have high spatial variability and show clustering behavior, with heterogeneity in scales that can be evaluated through multifractal analysis. Objective The objective of this study was to evaluate the weeds using analysis a no-till area. Methods Sampling conducted at 1,015 sampling points an experimental plot regular grid 5 × m (2.38 ha) no tillage. area cultivated triticale (Tr...

We have developed a phytochrome immunoaffinity purification procedure that yields undegraded oat (Avena sativa L., cv. Garry) phytochrome of greater than 98% purity within 2 hours when starting with a brushite-purified preparation. Immunoaffinity-purified phytochrome, except for its greater purity, is indistinguishable from conventionally purified phytochrome by gel exclusion chromatography, is...

We present a simple subtraction procedure of GDDSC as a modification of the original DSC and GDRDA methods. Genetically Directed Differential Subtraction Chain (GDDSC) is a process by which highly related genomes are compared in order to isolate tags carrying the polymorphisms. To detect specific DNA fragment (tag), we can then monitor offspring plants for efficient molecular breeding. The GDDS...

The Pyricularia genus includes several pathogenic fungi species that are associated with blast disease in more than 50 Poaceae plants (Ou 1985). Among these species, Pyricularia oryzae is the most important pathogen, due to its global distribution on plants from the Poaceae family. The blast disease caused by P. oryzae is responsible for severe losses in crops of high economic importance such a...
