Amygdalin is a cyanogenic diglucoside and constitutes the bitter component in bitter almond (Prunus dulcis). Amygdalin concentration increases in the course of fruit formation. The monoglucoside prunasin is the precursor of amygdalin. Prunasin may be degraded to hydrogen cyanide, glucose, and benzaldehyde by the action of the β-glucosidase prunasin hydrolase (PH) and mandelonitirile lyase or be...

Almond and sweet cherry are two economically important species of the Prunus genus. They both produce the cyanogenic glucosides prunasin and amygdalin. As part of a two-component defense system, prunasin and amygdalin release toxic hydrogen cyanide upon cell disruption. In this study, we investigated the potential role within prunasin and amygdalin and some of its derivatives in endodormancy re...

In order to evaluate effects of different survival strategy and canopy structure on cereal radiation use efficiency (RUE) under drought during grain filling, a pot experiment in spring barley (Hordeum vulgare L.) of cultivar Dobla (able for escape, no productive tiller) and Kompakt (one productive tiller) was conducted. There was no difference in current RUE for leaf dry mass (RUEL) between mai...

Michaels, T. E., Smith, T. H., Larsen, J., Beattie, A. D. and Pauls, K. P. 2006. OAC Rex common bean. Can. J. Plant Sci. 86: 733–736. OAC Rex is an upright indeterminate bush white bean (Phaseolus vulgaris L.) cultivar intended for use in areas with greater than 2800 crop heat units. It has good yield potential in either wide or narrow row production. It is resistant to races 1 and 15 of bean c...

Switching of symbiotic partners pervades most mutualisms, despite mechanisms that appear to enforce partner fidelity. To investigate the interplay of forces binding and dissolving mutualistic pairings, we investigated partner fidelity at the population level in the attine ant-fungal cultivar mutualism. The ants and their cultivars exhibit both broad-scale co-evolution, as well as cultivar switc...

introduction: almond (prunus amygdalus b.) is one of the most important crops consumed as a dry fruit and it is mainly adaptable to arid and semi-arid regions mostly suffering from salinity stress (8). soils with dry humidity regime are dominant in iran and in the world at large and mostly include regions with more evaporation than precipitation. this in turn leads to increased salinity of the ...
