Bacillus thuringiensis and its pest control potential as endophyte

open access: yesPest Management Science, EarlyView.
Bacillus thuringiensis (Bt) systemically colonizes tomato plants as endophyte, inducing midgut damage, fitness reduction and immune suppression in Spodoptera littoralis larvae feeding on Bt‐colonized leaves. The immune suppression enhances the susceptibility to Bt treatments, allowing a synergistic dual use of Bt commercial formulations, by combined ...

Spodoptera littoralis-Induced Lectin Expression in Tobacco [PDF]

open access: yesPlant and Cell Physiology, 2009
The induced defense response in plants towards herbivores is mainly regulated by jasmonates and leads to the accumulation of so-called jasmonate-induced proteins. Recently, a jasmonate (JA) inducible lectin called Nicotiana tabacum agglutinin or NICTABA was discovered in tobacco (N. tabacum cv Samsun) leaves.
