The basal defenses important in curtailing the development of the phloem-feeding silverleaf whitefly (Bemisia tabaci type B, SLWF) on Arabidopsis thaliana were investigated. Sentinel defense gene RNAs were monitored in SLWF-infested and control plants. SA-responsive gene transcripts accumulated locally (PR1, BGL2, PR5, SID2, EDS5, PAD4) and systemically (PR1, BGL2, PR5) during SLWF nymph feeding. In contrast, JA- and ET-dependent RNAs (PDF1.2, VSP, HEL, THI2.1, FAD3, ERS1, ERF1) were repressed or not modulated in SLWF-infested leaves. To test for a role of SA and JA pathways in basal defense, SLWF development on mutant and transgenic lines that constitutively activate or impair defense pathways was determined. By monitoring the percentage of SLWF nymphs in each instar, we show that mutants, which activate SA defenses (cim10) or impair JA-defenses (coi1), accelerated SLWF nymphal development. Reciprocally, mutants that activate JA defenses (cev1) or impair SA defenses (npr1, NahG) slowed SLWF nymphal development. Furthermore, when npr1 plants, which do not activate downstream SA defenses, were treated with MeJA, a dramatic delay in nymph development was observed. Collectively these results showed that SLWF-repressed, JA-regulated defenses were associated with basal defense to the SLWF.
