He nui, he kanorau hoki ngā harore nui o ngā matū koiora, ā, e kiia ana he rauemi koiora nui. He harore nui te Phellinus igniarius e whakamahia ana mō ngā mahi rongoā me ngā mahi kai, engari kei te tautohetia tonutia tōna whakarōpūtanga me tōna ingoa Latina. Mā te tātari i te whakarārangitanga wāhanga maha-ira, i whakaū ngā kairangahau nō tētahi puninga hou te Phellinus igniarius me ngā momo rite, ā, i whakatūria te puninga Sanghuangporus. Ko te harore honi Sanghuangporus lonicericola tētahi o ngā momo Sanghuangporus kua tautuhia puta noa i te ao. Kua aro nui te Phellinus igniarius nā ōna āhuatanga rongoā kanorau, tae atu ki ngā polysaccharides, ngā polyphenols, ngā terpenes, me ngā flavonoids. Ko ngā triterpenes ngā matū matua e kaha ana ki te rongoā o tēnei puninga, e whakaatu ana i ngā mahi antioxidant, antibacterial, me te anti-pukupuku.
He nui te kaha o ngā triterpenoids mō te tono arumoni. Nā te onge o ngā rauemi Sanghuangporus mohoao i roto i te taiao, he mea tino nui te whakapai ake i tōna whai huatanga biosynthetic me te hua. I tēnei wā, kua puta te ahunga whakamua ki te whakarei ake i te whakaputanga o ngā momo metabolites tuarua o Sanghuangporus mā te whakamahi i ngā matū whakaoho hei whakahaere i ngā rautaki whakapūkara i raro i te wai. Hei tauira, kua whakaatuhia e ngā waikawa ngako polyunsaturated, ngā kaiwhakaoho harore11 me ngā phytohormones (tae atu ki te methyl jasmonate me te waikawa salicylic14) te whakanui ake i te whakaputanga triterpenoid i roto i te Sanghuangporus. Ngā kaiwhakahaere tipu tipu(Ngā PGR)ka taea te whakahaere i te hanga koiora o ngā matū matū tuarua i roto i ngā tipu. I roto i tēnei rangahau, i rangahaua te PBZ, he kaiwhakahaere tipu tipu e whakamahia whānuitia ana hei whakahaere i te tipu tipu, te hua, te kounga me ngā āhuatanga ā-tinana. Ina koa, ka taea e te whakamahinga o te PBZ te awe i te ara hanga koiora terpenoid i roto i ngā tipu. Ko te whakakotahitanga o ngā gibberellins me te PBZ i whakanui ake i te ihirangi quinone methide triterpene (QT) i roto i te Montevidia floribunda. I whakarerekētia te hanganga o te ara terpenoid o te hinu lavender i muri i te maimoatanga ki te 400 ppm PBZ. Heoi, kāore he pūrongo mō te whakamahinga o te PBZ ki ngā harore.
Haunga ngā rangahau e aro ana ki te pikinga ake o te hanga triterpene, kua whakamāramahia hoki e ētahi rangahau ngā tikanga whakahaere o te hanga triterpene i roto i te Moriformis i raro i te mana o ngā matū whakaoho. I tēnei wā, kei te aro ngā rangahau ki te whakarerekētanga o ngā taumata whakapuakanga o ngā ira hanganga e pā ana ki te hanga triterpene i roto i te ara MVA, e hua ake ai te pikinga ake o te hanga terpenoid.12,14 Heoi, kāore anō kia mārama ngā ara kei raro i ēnei ira hanganga e mōhiotia ana, inā koa ko ngā āhuatanga whakawhiti e whakahaere ana i tā rātou whakapuakanga, i roto i ngā tikanga whakahaere o te hanga triterpene i roto i te Moriformis.
I roto i tēnei rangahau, i tirotirohia ngā pānga o ngā kukū rerekē o ngā kaiwhakahaere tipu tipu (PGR) ki te whakaputanga triterpene me te tipu mycelial i te wā o te whakapūtanga i raro i te wai o te honi (S. lonicericola). I muri mai, i whakamahia ngā metabolomics me ngā transcriptomics hei tātari i te hanganga triterpene me ngā tauira whakaaturanga ira e uru ana ki te biosynthesis triterpene i te wā o te maimoatanga PBZ. Nā ngā raraunga raupapatanga RNA me te bioinformatics i tautuhia te take whakawhiti ūnga o MYB (SlMYB). I tua atu, i hangaia ngā mutants hei whakaū i te pānga whakahaere o te ira SlMYB ki te biosynthesis triterpene me te tautuhi i ngā ira ūnga pea. I whakamahia ngā whakamātautau nekehanga nekeneke hiko (EMSA) hei whakaū i te taunekeneke o te pūmua SlMYB me ngā kaiwhakatairanga o ngā ira ūnga SlMYB. Hei whakarāpopototanga, ko te whāinga o tēnei rangahau he whakaoho i te biosynthesis triterpene mā te whakamahi i te PBZ me te tautuhi i te take whakawhiti MYB (SlMYB) e whakahaere tika ana i ngā ira biosynthetic triterpene tae atu ki te MVD, IDI, me te FDPS i roto i te S. lonicericola hei whakautu ki te whakaoho PBZ.
Nā te whakaoho o te IAA me te PBZ i tino whakanui ake te hanga triterpenoid i roto i te honi, engari he nui ake te kitea o te pānga whakaoho o te PBZ. Nō reira, i kitea ko te PBZ te whakaoho pai rawa atu i te kukū tāpiri o te 100 mg/L, he mea e tika ana kia rangahauhia anō.
