The COP9 (constitutive photomorphogenesis 9) signalosome (CSN) is a protein complex involved in the ubiquitin proteasome system and a common host target of diverse pathogens in Arabidopsis. The known derubylation function of the COP9 complex is carried out by subunit 5 encoded by AtCSN5A or AtCSN5B in Arabidopsis. A single CSN5-like gene (designated as TaCSN5) with three homeologues was identif...

Barilli E., Sillero J.C., Prats E., Rubiales D. (2014): Resistance to rusts (Uromyces pisi and U. viciae-fabae) in pea. Czech J. Genet. Plant Breed., 50: 135–143. Pea is the second most important food legume crop in the world. Rust is a pea disease widely distributed, particularly in regions with warm, humid weather. Pea rust can be incited by Uromyces viciae-fabae and by U. pisi. U. viciae-fab...

The evolution of akaganeite in rust layers strongly impacts the atmospheric corrosion behavior of steel during long-term exposure; however, the factors affecting the evolution of akaganeite and its mechanism of formation are vague. In this work, wet-dry cyclic corrosion tests were conducted to simulate long-term exposure. Quantitative X-ray diffraction analysis was employed to analyze variation...

It has important significance to improve monitoring the diseases and pest level and to maintain food security and ecological environment protection in China. There is a distinct difference on the chlorophyll content between the disease and health leaves after analyzing. Therefore the following bands, 470nm, 550nm, 635nm, 680nm, 800nm, sensitive to chlorophyll are used to monitoring the disease ...

Farming systems frameworks such as the Agricultural Production Systems simulator (APSIM) represent fluxes through the soil, plant and atmosphere of the systemwell, but do not generally consider the biotic constraints that function within the system. We designed a method that allowed population models built in DYMEX to interact with APSIM. The simulator engine component of the DYMEX population-m...

Rust, incited by Uromyces appendiculatus^ is a major disease in common bean {Phaseolus vulgaris L,). Plant growth habit is also an important trait. Indeterminate growth habit was first reported to be controlled by a single dominant gene (Fin) (Lamprecht, 1935). Molecular markers such as isozymes, RFLP, and RAPD, have been used to tag genes for many traits, particularly disease resistance in sev...

Stem or black rust of wheat caused by the fungus Puccinia graminis f. sp. tritici Ericks and Henn (Pgt) is an important disease on wheat worldwide. Pgt is an obligate biotroph, heteroceous in its life cycle and heterothallic in mating type. Seedlings of 41 emmer (Triticum dicoccum), 56 durum (T. durum) wheat accessions were tested for their response to stem rust (Puccinia graminis f. sp. tricti...

Future biomass yields are functionally related to the number of trees surviving at a given age. A stand level survival model was developed that incorporates competition of non-planted trees, site quality, and the incidence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme). The model consists of a system of two equations, one of which represents the number of survi...

Solutions of complex problems require intelligent systems that combine knowledge, techniques and methodologies, from different sources, considering environmental changes, for decision support improvement. Thus, it became necessary to apply robust methodologies to characterize the interaction among climatic variables related to epidemic progress. The objective of the present work was to evaluate...
