Cytoplasmic male sterility (cms) in rye (Secale cereale L.), especially cytoplasma PAMPA, is used commercially in hybrid breeding programmes. The development of molecular markers that are tightly linked to the numerous genes coding for pollen fertility is expected to have great impact in the field. Morphological and cytological analyses of plants from a three-way cross C394: [(S67P/94 x S38/94)...
"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...
In this Letter, we report Ge p-i-n avalanche photodetectors (APD) with low dark current (sub 1 μA below V(R)=5 V), low operating voltage (avalanche breakdown voltage=8-13 V), and high multiplication gain (440-680) by exploiting a point defect healing method (between 600°C and 650°C) and optimizing the doping concentration of the intrinsic region (p-type ~10¹⁷ cm⁻³). In addition, Raman spectro...
