Posachedwapa, gulu lofufuza la Professor Song Chuankui wa State Key Laboratory of Tea Biology and Resource Utilization of Anhui Agricultural University and the research group of Researcher Sun Xiaoling of the Tea Research Institute of the Chinese Academy of Agricultural Sciences anasindikiza pamodzi mutu wakuti “Plant , Cell & Environment (Impact Factor 7.228)” Kusakhazikika kwa Herbivore kumakhudza zomwe njenjete amakonda powonjezeraβ-Kutulutsa kwa Ocimene kwa zomera za tiyi zoyandikana nazo", kafukufukuyu adapeza kuti kusakhazikika komwe kumayambitsidwa ndi kudyetsedwa kwa mphutsi za tiyi kumatha kulimbikitsa kutulutsidwa kwa tiyi.β-ocimene kuchokera ku zomera za tiyi zoyandikana nazo, potero zimawonjezera zomera zoyandikana nazo. Kutha kwa mitengo ya tiyi yathanzi kuthamangitsa akuluakulu a tiyi. Kafukufukuyu athandiza kumvetsetsa momwe chilengedwe chimagwirira ntchito komanso kukulitsa kumvetsetsa kwatsopano kwa njira yolumikizirana ndi ma volatiles-mediated signal pakati pa zomera.
Pachisinthiko cha nthawi yayitali, zomera zapanga njira zosiyanasiyana zodzitetezera ndi tizirombo. Pamene kudyedwa ndi herbivorous tizilombo, zomera adzamasula zosiyanasiyana kosakhazikika mankhwala, amene osati kuchita mwachindunji kapena mosalunjika chitetezo mbali, komanso nawo mwachindunji kulankhulana pakati pa zomera ndi zomera monga zizindikiro mankhwala, activating chitetezo Poyankha zomera zoyandikana. Ngakhale kuti pakhala pali malipoti ambiri okhudzana ndi kugwirizana pakati pa zinthu zowonongeka ndi tizilombo towononga, ntchito ya zinthu zosasunthika poyankhulana ndi zizindikiro pakati pa zomera ndi njira zomwe zimathandizira kukana sizikudziwikabe.
Pakafukufukuyu, gulu lofufuza lidapeza kuti mbewu za tiyi zikadyetsedwa ndi mphutsi za tiyi, zimatulutsa zinthu zosiyanasiyana zosakhazikika. Zinthuzi zimatha kupititsa patsogolo luso lothamangitsa mbewu zoyandikana nazo polimbana ndi akuluakulu a tiyi (makamaka zazikazi zikakwera). Kupyolera mu kusanthula kowonjezereka komanso kuwonjezereka kwa zowonongeka zomwe zimatulutsidwa kuchokera ku zomera za tiyi zathanzi zapafupi, kuphatikizapo kusanthula khalidwe la munthu wamkulu wa tiyi, anapeza kutiβ-ocilerene adagwira ntchito yofunikira momwemo. Zotsatira zake zidawonetsa kuti chomera cha tiyi (cis) - 3-hexenol, linalool,α-farnesene ndi terpene homologue DMNT imatha kulimbikitsa kutulutsidwa kwaβ-ocimene kuchokera ku zomera zapafupi. Gulu lofufuza lidapitilira kuyesa koletsa njira, kuphatikiza zoyeserera zenizeni zowoneka bwino, ndipo zidapeza kuti kusasunthika komwe kumatulutsidwa ndi mphutsi kumatha kulimbikitsa kumasulidwa kwaβ-ocimene kuchokera kumitengo ya tiyi yapafupi yathanzi kudzera munjira zowonetsera za Ca2+ ndi JA. Kafukufukuyu adawonetsa njira yatsopano yolumikizirana pakati pa zomera, yomwe ili ndi tanthauzo lofunikira pakukhazikitsa njira zothana ndi tizirombo tobiriwira komanso njira zatsopano zothana ndi tizirombo.
