Interactions of -7 with Phytophagous Mites Following Different Application Strategies.

is a generalist entomopathogenic fungus known to be virulent against Acari. We investigated -7 (Mb7) interactions in three systems of phytophagous mites and their respective plant hosts: Volkamer lemon () and the citrus rust mite ; common bean () and the two-spotted spider mite ; and spring onion () and the bulb mite . All three mite species were susceptible to directly applied Mb7 conidia.

Corrected and Republished from: Activation Status-Coupled Transient S-Acylation Determines Membrane Partitioning of a Plant Rho-Related GTPase.

ROPs or RACs are plant Rho-related GTPases implicated in the regulation of a multitude of signaling pathways that function at the plasma membrane via posttranslational lipid modifications. The relationships between ROP activation status and membrane localization has not been established. Here, we show that endogenous ROPs, as well as a transgenic His-green fluorescent protein (GFP)- ROP6 (AtROP6) fusion protein, were partitioned between Triton X-100-soluble and -insoluble membranes.

Dual role of the pigmentation gene B in affecting carotenoid and vitamin E content in squash (Cucurbita pepo) mesocarp.

The yellow and orange colorations of the mesocarp of pumpkins and squash of Cucurbita pepo are due to the presence of carotenoid pigments that also greatly contribute to their nutritional value. Carotenoids, as well as tocopherols (vitamin E), are isoprenoid compounds formed by branches of a common biosynthetic pathway. Photodiode array HPLC analysis was used to simultaneously determine the content and composition of fruit-flesh carotenoids and tocopherols in five pairs of near-isogenic lines differing in the allelic state of genes previously identified as having profound effects on fruit color.
