El pan es un alimento de consumo masivo que puede mejorarse nutricionalmente mediante el agregado distintos ingredientes. La harina avena (Avena Sativa L.) con trigo buena calidad industrial se podrían combinar para obtener productos panificados características aceptables consumidor y mejoras nutricionales. objetivo este trabajo fue analizar fisicoquímicamente las harinas diferentes variedades ...

Microorganisms which contaminate animal feeds pose a threat not only to animals but also indirectly to humans through their consumption of products of animal origin. The aim of the present study was to assess microbiological cleanness of selected resources and ready-made feed mixtures before and after thermal processing. The results indicated that the most bacteriologically contaminated resourc...

Using monoclonal antibodies to the plant photoreceptor, phytochrome, we have investigated by immunogold electron microscopy the rapid, red light-induced, intracellular redistribution (termed "sequestering") of phytochrome in dark-grown Avena coleoptiles. Pre-embedding immunolabeling of 5-micron-thick cryosections reveals that sequestered phytochrome is associated with numerous, discrete structu...

A spectral, immunochemical, and proteolytic characterization of native 120-kilodalton (kD) phytochrome from Cucurbita pepo L. is presented and compared with that previously reported for native 124-kD phytochrome from Avena sativa. The molecule was partially purified ( approximately 200-fold) in the phytochrome-far red-absorbing form (Pfr) in the presence of the protease inhibitor, phenylmethyls...

Introduction One fact that is agreed upon in the literature regarding the mechanism of phototropism is that the growth curvature results from an unequal distribution of auxin. There are at least three hypotheses as to how unilateral illumination causes the unequal distribution: 1. Photoinactivation of auxin on the lighted side of the plant. 2. A differential change in the rate of synthesis of a...
