Muva nje, iqembu locwaningo likaSolwazi Song Chuankui we-State Key Laboratory of Tea Biology and Resource Utilization of Anhui Agricultural University kanye neqembu locwaningo loMcwaningi u-Sun Xiaoling we-Tea Research Institute ye-Chinese Academy of Agricultural Sciences lishicilele ngokuhlanganyela isihloko esithi “Plant. , Iseli & Imvelo (Impact Factor 7.228)” Izivunguvungu ezibangelwa yi-herbivore zithonya ukukhetha kwebhu ngokukhulisaβ-Ukukhishwa kwe-Ocimene kwezitshalo zetiye ezingomakhelwane”, ucwaningo lwathola ukuthi ukuguquguquka okubangelwa ukuphakelwa kwezibungu zetiye kungakhuthaza ukukhululwa kweβ-ocimene evela ezitshalweni zetiye ezingomakhelwane, ngaleyo ndlela andisa izitshalo zetiye ezingomakhelwane. Ikhono lezihlahla zetiye ezinempilo ukuxosha abantu abadala betiye looper. Lolu cwaningo luzosiza ukuqonda imisebenzi yemvelo yokuguquguquka kwezitshalo futhi kwandise ukuqonda okusha kwendlela yokuxhumana yesignali eguquguqukayo phakathi kwezitshalo.

Esikhathini eside sokuziphendukela kwemvelo, izitshalo zenze amasu anhlobonhlobo okuzivikela anezinambuzane. Lapho zidliwa izinambuzane ezidla uhlaza, izitshalo zizokhipha izinhlanganisela ezihlukahlukene eziguquguqukayo, ezingagcini nje ukudlala indima yokuzivikela eqondile noma engaqondile, kodwa futhi zihlanganyele ekukhulumisaneni okuqondile phakathi kwezitshalo nezitshalo njengezibonakaliso zamakhemikhali, kusebenze impendulo yokuzivikela yezitshalo ezingomakhelwane. Nakuba kube nemibiko eminingi yokusebenzelana phakathi kwezinto eziguquguqukayo nezinambuzane, indima yezinto eziguquguqukayo ekuxhumaneni kwesignali phakathi kwezitshalo kanye nendlela ezikhuthaza ngayo ukumelana namanje akukacaci.

Kulolu cwaningo, ithimba locwaningo lithole ukuthi uma izitshalo zetiye ziphakelwa izibungu zetiye looper, zikhulula izinto ezihlukahlukene ezishintshashintshayo. Lezi zinto zingathuthukisa ikhono lokuxosha izitshalo ezingomakhelwane ngokumelene nabantu abadala betiye (ikakhulukazi abesifazane ngemva kokukhwelana). Ngokuhlaziywa okwengeziwe kwekhwalithi nokwamanani okuguquguquka okukhishwe ezitshalweni zetiye ezinempilo eziseduze, kuhlanganiswe nokuhlaziywa kokuziphatha kwe-loop yetiye yabantu abadala, kwatholakala ukuthiβ-ocilerene wadlala indima ebalulekile kuwo. Imiphumela yabonisa ukuthi isitshalo setiye esikhishwe (cis)- 3-hexenol, linalool,α-farnesene kanye ne-terpene homologue DMNT ingakhuthaza ukukhululwa kweβ-ocimene ezitshalweni eziseduze. Ithimba labacwaningi liqhubekile nokuhlola okubalulekile kokuvimbela indlela, okuhlanganiswe nokuhlolwa kokuchayeka okuguquguqukayo, futhi lathola ukuthi ukuguquguquka okukhishwe izibungu kungashukumisa ukukhululwa kweβ-ocimene kusuka ezihlahleni zetiye ezinempilo eziseduze ngokusebenzisa izindlela zokusayina ze-Ca2+ ne-JA. Ucwaningo lwembule indlela entsha yokuxhumana kwesignali eshintshashintshayo phakathi kwezitshalo, enenani elibalulekile lereferensi ekuthuthukisweni kokulawula izinambuzane zetiye eliluhlaza kanye namasu amasha okulawula izinambuzane.
