Climate change can threaten the reproductive success of plants, both directly, through physiological damage during increasingly extreme weather events, and indirectly, through disruption of plant-pollinator interactions. To explore how plant-pollinator interactions are modified by extreme weather, we exposed faba bean (Vicia faba) plants to elevated temperature for 5 d during flowering, simulat...

The effects of 5-hydroxyuracil (5-HU) (isobarbituric acid) upon cell elongation, mitosis, and DNA synthesis were studied in Vicia faba roots. 5-HU had no consistent effect upon root elongation. It blocked DNA synthesis (analyzed by photometric measurements of Feulgen dye in nuclei) during the first 6 hours of treatment; the block spontaneously disappeared by the 12th hour of treatment. Uracil a...

BACKGROUND Vicia sativa (the common vetch) possesses a predominant zygomorphic flower and belongs to the subfamily Papilionoideae, which is related to Arabidopsis thaliana in the eurosid II clade of the core eudicots. Each vetch flower consists of 21 concentrically arranged organs: the outermost five sepals, then five petals and ten stamens, and a single carpel in the center. METHODOLOGY/PRIN...

A quantitative method was developed to measure the binding of fluorescent-labeled lentil (Lens esculenta Moench), pea (Pisum sativum L.), broad bean (Vicia faba L.), and jackbean (Canavalia ensiformis L., DC.) lectins to various Rhizobium strains. Lentil lectin bound to three of the five Rhizobium leguminosarum strains tested. The number of lentil lectin molecules bound per R. leguminosarum 128...

Esau sold his birthright to Jacob for a mess of red pottage, a dish thought to be the red lentil (Lens culinaris Medik.). Taking today's price of US $800 per tonne, this particular pulse must seem to be an attractive crop to many farmers. Unfortunately, red lentils are a rather poor yielding crop, so in the late 1980's when it was noted in Australia that the pinkish cotyledons of the “blanche f...

HE characteristics of mutational damage recovered from spermatogonial cells Tare important for considerations of genetic risks from radiation. The genetic and cytological types of mutations recovered from spermatogonia determine the chances of genetic damage offered the ensuing populations. To study these characteristics, radiation studies were carried out in Drosophila where well defined genet...
