Local and systemic changes in squash gene expression in response to silverleaf whitefly feeding.
Squash genes (SLW1 and SLW3) induced systemically after silverleaf whitefly feeding were identified. Differences in the local and systemic expression of SLW1 and SLW3 after feeding by the closely related silverleaf and sweetpotato whiteflies were observed. Temporal and spatial studies showed that SLW1 and SLW3 were induced when second, third, and fourth nymphal instars were feeding. Although on...
متن کاملMultitrophic interactions of the silverleaf whitefly, host plants, competing herbivores, and phytopathogens.
Our laboratory found that silverleaf whitefly (SLW; Bemisia argentifolii Bellows & Perring) feeding alters host plant physiology and chemistry. The SLW induces a number of host plant defenses, including pathogenesis-related (PR) protein accumulation (e.g., chitinases, beta-1,3-glucanases, peroxidases, chitosanases, etc.). Induction of the PR proteins by SLW feeding occurs in various plant speci...
متن کاملThe nymphal-adult molt of the silverleaf whitefly (Bemisia argentifolii): Timing, regulation, and progress.
The developmental progress of silverleaf whitefly (Bemisia argentifolii) 3rd instars and 4th instar/pharate adults was monitored using a tracking system that had been designed to identify synchronous individuals in another species of whitefly, the greenhouse whitefly, Trialeurodes vaporariorum. When reared on greenbean under conditions of LD 16:8 and a temperature of 26 +/- 2 degrees C, the bod...
متن کاملPurification and properties of an unusual NADPH-dependent ketose reductase from the silverleaf whitefly
Sorbitol accumulates in the silverleaf whitefly when this insect is exposed to elevated temperatures. Synthesis of sorbitol in the silverleaf whitefly is catalyzed by an unconventional enzyme that converts fructose to sorbitol using NADPH as the coenzyme. In the present study, the NADPH-dependent ketose reductase from adult whiteflies was purified to apparent homogeneity and characterized. The ...
متن کاملSilverleaf whitefly induces salicylic acid defenses and suppresses effectual jasmonic acid defenses.
The basal defenses important in curtailing the development of the phloem-feeding silverleaf whitefly (Bemisia tabaci type B; SLWF) on Arabidopsis (Arabidopsis thaliana) were investigated. Sentinel defense gene RNAs were monitored in SLWF-infested and control plants. Salicylic acid (SA)-responsive gene transcripts accumulated locally (PR1, BGL2, PR5, SID2, EDS5, PAD4) and systemically (PR1, BGL2...
