Phenolic acids have been identified in a variety of legumes including lima bean, broad bean, common bean, pea, jack bean, goa bean, adzuki bean, hyacinth bean, chicking vetch, garbanzo bean, dral, cow bean, rice bean, mung bean and soybean. The present study was carried out with the following aims: (1) to identify and quantify the individual phenolic acid and determine the total phenolic conten...

BACKGROUND Animal-derived elicitors can be used by plants to detect herbivory but they function only in specific insect-plant interactions. How can plants generally perceive damage caused by herbivores? Damaged-self recognition occurs when plants perceive molecular signals of damage: degraded plant molecules or molecules localized outside their original compartment. METHODOLOGY/PRINCIPAL FIND...

A free sulfhydryl group previously has been shown to be required for carbohydrate binding to the lectin from lima bean (Phaseolus lunatus) (Gould, N. R. and Scheinberg, S. L. (1970) Arch. Biochem. Biophys. 141, 607-613). Modification of this group by sulfhydryl reagents was specifically inhibited by D-GalNAc. We have further examined the reactivity of sulfhydryl groups in lima bean lectin with ...

The amino acid sequences of garden bean (Phaseolus vulgaris) trypsin inhibitor II and a related molecular species II' have been examined. The entire sequence of II' has been determined with the exception of five internal residues. The garden bean inhibitors are highly homologous to the Bowman-Birk soybean inhibitor and lima bean trypsin inhibitor IV. The trypsin-reactive site has been located i...

A blend of volatile organic compounds (VOCs) emitted from plants induced by herbivory enables the priming of defensive responses in neighboring plants. These effects may provide insights useful for pest control achieved with transgenic-plant-emitted volatiles. We therefore investigated, under both laboratory and greenhouse conditions, the priming of defense responses in plants (lima bean and co...

Plant domestication can be seen as a long-term process that involves a complex interplay among demographic processes and evolutionary forces. Previous studies have suggested two domestication scenarios for Lima bean in Mesoamerica: two separate domestication events, one from gene pool MI in central-western Mexico and another one from gene pool MII in the area Guatemala-Costa Rica, or a single d...

The diversity of a collection of 21 bradyrhizobial isolates from Lima bean (Phaseolus lunatus L.) was assayed by molecular methods. Moderately high to high genetic diversity was revealed by multilocus enzyme electrophoresis (MLEE) analysis of seven enzyme loci and genomic fingerprints with ERIC and BOX primers. Two groups with differences in growth rate were found among the isolates and their d...

Plants respond to attack by herbivores or pathogens with the release of volatile organic compounds. Neighbouring plants can receive these volatiles and consecutively induce their own defence arsenal. This 'plant communication', however, appears counterintuitive when it benefits independent and genetically unrelated receivers, which may compete with the emitter. As a solution to this problem, a ...

J Econ Entomol 82(6): 1825-1829 (1989) ABSTRACT Oriental fruit moth, Ctapholita molesta (Busck), was reared on modifications of a previously developed small lima bean diet Initial experiments showed that different types of beans substituted for lima beans produced similar yields of oriental fruit moth pupae Fresh, thinning apples provided the best diet for high yields and high pupal weights, bu...
