Te whakapai ake i te kounga o ngā hua me te pupuri tonu i te kounga noate tipu o te tipuhe wero nui tonu tēnei i roto i te ahuwhenua. E kī ana tētahi rangahau hou he māmā ake pea te whakatutuki i tēnei taurite i te whakaaro o mua. Kua kitea e ngā kaipūtaiao mā te whakarei ake i te mahi a te "ira ma" kua tiakina ka taea te whakapai ake i te uara kai me ngā āhuatanga organoleptic o te hua i te wā kotahi. Mā te whakarei ake i te whakaaturanga o te ira e pā ana ki te tRNA, i whakapiki ake te tīma rangahau i ngā taumata o ngā anthocyanin me ngā terpenoid—ngā matū e pā ana ki te tae, te kakara, me ngā āhuatanga antioxidant o te hua. Kāore he pānga ine o ēnei whakapainga ki te whanaketanga tipu, te rahi o te hua, te ihirangi huka rānei. E whakaatu ana ngā hua i tētahi mahi ohorere mō ngā ira e pā ana ki te mahi pūtau taketake, e whakaatu ana ka taea hoki e rātou te pā ki ngā āhuatanga matua o te pākia o te hua.
He mea nui te mahi a ngā anthocyanin me ngā terpenoid ki te tae, te reka, te kakara, me te uara kai whānui o ngā hua. Heoi, ko ngā ngana ki te whakanui ake i te ihirangi o ēnei matū ka arahi pea ki ngā pānga taha kāore e hiahiatia. Nā te mea he hononga tata tō rātou whakaputanga ki ngā homoni tipu. Hei tauira, ko ngā cytokinin e whakahaere ana i te tipu o te tipu me te pākia tuarua, nō reira mā te whakarerekē i ō rātou taumata ka taea te whakarerekē i te hanganga me ngā āhuatanga tipu o ngā tipu.
Kāore i te tino arohia tētahi momo ira e pā ana ki te cytokinin—ko ngā isopentenyl transferases momo tRNA—e kore nei e mōhiotia whānuitia. E whakaarohia ana ka mahi ēnei ira i ngā mahi pūtau noa, kaua ki te whakahaere kaha i ngā āhuatanga o te tipu. Kāore anō kia mārama mēnā ka taea e rātou te whakapai ake i te kounga o te hua me te kore e pā ki te tipu o te tipu, ā, he mea tika kia rangahaua anō.
I whakaputahia e ngā kairangahau o Te Whare Wānanga Ahuwhenua o Nanjing me Te Whare Wānanga o Connecticut tētahi tuhinga i roto i te puka *Horticultural Research*, e tūhuratia ana tēnei mea pea mā te whakamahi i ngā rōpere mohoao hei tauira. I arotahi rātou ki tētahi ira tiaki whare e kiia nei ko FveIPT2. Mā te whakarerekē ira o ngā tipu hei whakanui ake i te taumata whakaaturanga o tēnei ira, i kite rātou i tētahi whakapainga nui o te kounga o ngā hua.
He nui ake ngā taumata o ngā anthocyanin me ngā terpenoid i roto i ngā hua pakeke i ngā tipu whakawhiti ira, ki te whakataurite ki ngā tipu momo mohoao, engari kāore i kitea he rerekētanga o te tipu, te rahi o te hua, te nui rānei o te huka. E wero ana tēnei kitenga i te whakapono roa e mau tonu ana ko ngā ira tiaki whare he mahi kore mahi noa iho, ā, e whakaatu ana i tō rātou kaha nui ki te whakapai ake i te hua.
Kei roto te ira FveIPT2 i te whakarerekētanga o te tRNA, ā, e pā ana ki te hanga o te cis-zeatin (he cytokinin). Kāore i rite ki ētahi atu ira e pā ana ki te cytokinin, he pānga nui ki te tipu o te tipu, ko te pikinga o te mahi a te FveIPT2 ka puta he huringa iti noa iho i roto i ngā taumata cytokinin whānui. Ka haere tonu te whanaketanga o te tipu me te kore he āhuatanga rerekē e kitea ana. Ka puta te puāwaitanga me te hua e ai ki te tumanako, kāore he huringa o te taumaha, te āhua, te reka rānei o te hua.
Ahakoa te tipu pumau o ngā tipu, i pāngia e ngā huringa nui o te hanganga matū o ngā hua. I piki ake ngā taumata o ngā anthocyanin, flavonoids, me ngā matū phenolic, ā, i hua ake he tae whero kaha ake. I whakaatuhia e te tātari taipitopito he pikinga nui o ngā taumata o ngā anthocyanin motuhake e iwa, tae atu ki ngā matū i ahu mai i te cyanidin me te pelargonidin, e mōhiotia ana mō ō rātou āhuatanga antioxidant.
I taua wā anō, tata ki te haurua o ngā pūhui terpenoid i kitea i piki ake. Kei roto i ēnei pūhui terpenoid ngā monoterpenes, ngā sesquiterpenes, me ngā triterpenes, he mea nui ēnei ki te kakara me te reka.
Kāore ēnei huringa i te herea noa ki te tae me ngā wāhanga kai. I piki ake ngā taumata o ngā matū kakara e pā ana ki ngā kakara putiputi reka, pērā i te linalool. I tetahi atu taha, i heke iho ngā taumata o ngā matū e pā ana ki ngā kakara kapia, kakara kakara. I whakaūhia e ngā rangahau whakaputa ira kua kaha ake ngā ara matua e kawe ana i ēnei matū.
Ina huihuia, e whakaatu ana ēnei hua ka taea e FveIPT2 te whakapai ake i te matū o te hua me te kore e puta he huringa homoni noa e pā ana ki te tipu.
I kī ngā kairangahau, "E whakaatu ana tēnei rangahau he tino motuhake, he tino nui hoki ngā pānga o ngā mea e kīia nei e tātou ko ngā 'ira tiaki whare'. Mā te arotahi ki ngā ira momo-tRNA kaua ki ngā kaiwhakahaere homoni tuku iho, i taea e mātou te whakapai ake i te tae o te hua, te reka, me te hanganga kai me te kore e pā ki te tipu, engari he pānga kino te hangarau pākia ki te tipu. E kī ana ēnei hua ka taea e ngā ara pūtau taketake te awe mārire i te kounga o te hua, ka hoatu ki ngā kaiwhakatupu he taputapu hou e whai hua ana, e ngawari ana hoki."
E whakaatu ana ngā hua he tikanga whai hua, he tikanga whai hua hoki a FveIPT2 mō te whakapai ake i te kounga o ngā hua o ngā rōpere me ētahi atu hua ahuwhenua. Nā te mea ka whakanui ake tēnei tikanga i te nui o ngā tae whai hua me ngā matū kakara, me te kore e whakaiti i te hua, i te oranga rānei o te tipu, he mea tino nui tēnei mō te whakatipu hua ahuwhenua kounga teitei.
I te whānui, ka werohia e tēnei rangahau te whakaaro ko ngā ira tiaki whare ka uru noa ki ngā tukanga pūtau noa. Mā te tautuhi i tō rātou awe ki te pākia o te tinana tuarua, ka whakaarohia e te rangahau he rautaki hou hei whakanui ake i ngā hua o te hua me te pupuri tonu i te kounga.
Nā te Academy of Sciences o te Whare Wānanga Ahuwhenua o Nanjing tēnei tuhinga i whakarato. Kia mōhio: Me whakatika pea ngā ihirangi nā runga i ngā whakaritenga hōputu me te roa.
