"Flour dust" refers to dust coming from fmely milled or othenvise processed cereal. Hypersensitivity reactions as well as irritant syrnptoms caused by flour dust constitute a well recognized occupational problem world-wide. Most data on flour dusts have been derived fiom studies on wheat (Triticum sp.) and rye (Secale cereale), and to a lesser extent on barley (Hordeum sp.) and oats (Avenea sat...

A comparative study of the spectral sensitivity of anthocyanin production in dark-grown and light-pretreated systems was carried out in Brassica oleracea L., Lycopersicon esculentum Mill., Secale cereale L. and Spirodela polyrrhiza L. Light pretreatments bring about an enhancement of the inductive, red-far red reversible response in all systems, a decrease of the continuous irradiation response...

In order to understand a physiologi¢ al role of chitinases in rye, the localization and accumulatien of rye seed chitinase-a and -c (RSC-a and -c) in the seeds were studied by imm"nochemical methods. An antiserum specific to the chitin-binding domain (CB-domain), whicb is an N-terminal part of RSC-a, and an antiserum specific to the catalytic region of RSC-a and RSC-c were used. An immunoblot a...

Seed predation is an important biotic filter that can influence abundance and spatial distributions of native species through differential effects on recruitment. This filter may also influence the relative abundance of nonnative plants within habitats and the communities' susceptibility to invasion via differences in granivore identity, abundance, and food preference. We evaluated the effect o...

Norflurazon is a selective pyridazinone herbicide excessively employed in the control of many annual grasses and broad-leaved weeds. This chemical causes plant bleaching due to the inhibition of the carotenoid pigment biogenesis as well as induces irreparable changes to chloroplasts, which are considered the organelles where the biosynthesis of resorcinolic lipids takes place. Resorcinolic lipi...

Intensive vegetable production areas were surveyed in the provinces of Almería (35 sites) and Barcelona (22 sites), Spain, to determine the incidence and identity of Meloidogyne spp. and of fungal parasites of nematode eggs. Two species of Meloidogyne were found in Almería-M. javanica (63% of the samples) and M. incognita (31%). Three species were found in Barcelona, including M. incognita (50%...

Canarium L. is used in folk medicine as anti-inflammatory, antibacterial, antifungal, antitumor, heptoprotective, antioxidant, and anti diabetic properties. The present study investigeated the invivo anti-inflammatory activity of  essential oil obtained by hydrodistillation of resin of Canarium strictum Roxb. In the current study, anti-inflammatory activity of essential oil of...
