The aging process of the nematode Caenorhabditis elegans in bacterial and axenic culture.
Particular attention was paid to the rate of backwardly directed somatic waves, pharyngeal bulb pulsations, the interval between defecations and oviposition in wild type C. elegans, which lived significantly longer in axenic culture than in bacteria.
Control of Root-knot Nematodes on Tomato by Lectins.
Significant control of tomato root knot was achieved by applications of the lectins Concanavalin A (Con A) and Limax flavus agglutinin in greenhouse, growth chamber, and microplot trials. Four
Caenorhabditis elegans and Panagrellus redivivus: enzyme-mediated modification of chemotaxis.
Experimental and supporting evidence is presented that behavioral modification resulted from functional impairments to receptors located within chemosensory sensilla.
Streptomyces costaricanus sp. nov., isolated from nematode-suppressive soil.
The results of a number of biochemical tests and a profile analysis of the hydrolyzable fatty acids indicated that CR-43T differs from previously described species.
Histochemical Localization and Nematoxicity of Terpenoid Aldehydes in Cotton
In heahhy cotton, except flu" random occasional occttrrence in cortical cells, terpenoid aldehydes (TA) are localized in the epidermis and, even there, are absent from the tip 2-4 cm of the root.
Nematode chemotaxis and possible mechanisms of host/prey recognition
It has long been recognized that free-living nematodes utilize specific recogni­ tion mechanisms for finding their hosts or prey in the soil, and molecular recognition of "good" and "bad" bacteria undoubtedly comes into play, but here again definitive data are lacking.
Water Translocation of Diazinon-C14 and Parathion-S35 off a Model Cranberry Bog and Subsequent Occurrence in Fish and Mussels
Transportation of diazinon-C14 and parathion-S35 off a model cranberry bog following a simulated frost protection flood was shown 24 hr after application, and fish appear able to metabolize these accumulated chemicals at a faster rate than the mussels.
