Nonsense-mediat.d mRNA decay （NMD） is an import.nt.mRNA qualit. surveillance pat.way in all eukaryot.s t.at.eliminat.s aberrant.mRNAs derived from various sources. t.ree NMD fact.r prot.ins, UPF1, UPF2, and UPF3 are required for t.e NMD process and were found t. be also involved in cert.in st.ess responses in mammalian and yeast.cells. Using Arabidopsis t.aliana mut.nt. of UPF1 and UPF3 and UPF2-silenced lines （irUPF2）, we examined t.e involvement.of UPF1, UPF2, and UPF3 in development.and in response t. st.esses, wounding and infect.on by Pseudomonas syringae pv. t.mat. st.ain DC3000. Under t.e long （16 h） phot.period condit.on, Arabidopsis having a defect.in NMD fact.rs exhibit.d alt.red morphologies of various organs, dist.rbed homeost.sis of wounding-induced jasmonic acid and pat.ogen-elicit.d salicylic acid, and abnormal wounding- and met.yl jasmonat.-induced changes in t.e t.anscript.levels of t.o defense-relat.d genes, LOX2 and VSP2. Import.nt.y, when plant. were cult.vat.d under t.e short.（10 h） phot.period condit.on, mut.nt. of UPF1 and UPF3 and irUPF2 showed smaller differences from t.e wild-t.pe plant. in growt. and st.ess-induced responses. t.ese dat. suggest.a complex regulat.ry net.ork, likely composed of light.signaling and NMD fact.r-mediat.d pat.ways, in influencing plant.development.and adapt.on t. environment.l st.esses.

DICER-like （DCL） prot.ins produce small RNAs t.at.silence genes involved in development.and defenses against.viruses and pat.ogens.

Nearly half a cent.ry ago insect.herbivores were found t. induce t.e format.on of green islands by manipulat.ng cyt.kinin （CK） levels. However, t.e response of t.e CK pat.way t. at.ack by chewing insect.herbivores remains unclear. Here, we charact.rize t.e CK pat.way of Nicot.0}a at.enuat. （t.rr. ex S. Wat..） and it. response t. wounding and percept.on of herbivoreassociat.d molecular pat.erns （HAMPs）. We ident.fied 44 genes involved in CK biosynt.esis, inact.vat.on, degradat.on, and signaling. Leaf wounding rapidly induced t.anscript.onal changes in mult.ple genes t.roughout.t.e pat.way, as well as in t.e levels of CKs, including isopent.nyladenosine and cis-zeat.n riboside; percept.on of HAMPs present.in t.e oral secret.ons （OS） of t.e specialist.herbivore Manduca sext. amplified t.ese responses. t.e jasmonat. pat.way, which t.iggers many herbivore-induced processes, was not.required for t.ese HAMP-t.iggered changes, but.rat.er suppressed t.e CK responses. Int.rest.ngly CK pat.way changes were observed also in syst.mic leaves in response t. wounding and OS applicat.on indicat.ng a role of CKs in mediat.ng long dist.nce syst.mic processes in response t. herbivory. Since wounding and grasshopper OS elicit.d similar accumulat.ons of CKs in Arabidopsis t.aliana L., we propose t.at.CKs are int.gral component. of wounding and HAMP-t.iggered responses in many plant.species.
