BACKGROUND Measuring genome size by flow cytometry assumes direct proportionality between nuclear DNA staining and DNA amount. By 1997 it was recognized that secondary metabolites may affect DNA staining, thereby causing inaccuracy. Here experiments are reported with poinsettia (Euphorbia pulcherrima) with green leaves and red bracts rich in phenolics. METHODS DNA content was estimated as flu...

Abstract We have used the Arecibo Telescope and Green Bank (GBT) to carry out a deep search for H i 21 cm emission from large sample of “Green Pea” galaxies, yielding 19 detections, upper limits on mass. obtain masses M ≈ (4–300) × 10 8 ⊙ with median mass 2.6 9 ; non-detections, 3 σ limit is 5.5 . These are first estimates atomic gas content Pea galaxies. find that -to-stellar ratio in Peas con...

Continuous flow microwave heating is a promising alternative to conventional heating for aseptic processing of low-acid vegetable purees. However, non-uniform temperature distribution and control of processing parameters are the major hurdles in the implementation of continuous flow microwave heating. This study was undertaken to overcome issues associated with the scale-up of a continuous flow...

The grass-legume mixture formulation is an important criterion to improve biomass availability with improved balance of the nutritive components. objective ofthis reseach was determine yield and forage quality traits (green fodder yield, dry matter yield) chemical composition (protein, fibre mineral contents) field pea (Pisum sativum) oat (Avena sativa) their mixtures under subtropical conditio...

HIGHLIGHTS Adulteration of pistachio products with green pea is common due to price issues. We identified the presence down 0.1% developed protocol. HRM fast and precise for testing authenticity powdered pistachio.

The leaf nitrogen content is generally accepted as an indicator of food quality and as a factor affecting host selection by phytophagous insects. The alate pea aphids (Acyrthosiphon pisum Harris, Aphididae) were given a choice among non-nodulated pea plants (Pisum sativum L.) supplied with one of four nitrate-N levels (0, 3, 15 and 30 mM). When whole plants were exposed to aphids for 7 days, th...

The cellular and subcellular localization of endogenous nitric oxide (NO.) in leaves from young and senescent pea (Pisum sativum) plants was studied. Confocal laser scanning microscopy analysis of pea leaf sections with the fluorescent probe 4,5-diaminofluorescein diacetate revealed that endogenous NO. was mainly present in vascular tissues (xylem and phloem). Green fluorescence spots were also...

We investigated the protective effects of a viral vector based on an Apple latent spherical virus (ALSV) harboring a segment of the Bean yellow mosaic virus (BYMV) genome against mosaic diseases in pea, broad bean, and eustoma plants caused by BYMV infection. In pea plants pre-inoculated with the ALSV vaccine and challenge inoculated with BYMV expressing green fluorescence protein, BYMV multipl...
