Kukula kwa 5-aminolevulinic acid kumawonjezera kuzizira kwa zomera za phwetekere.

      Monga imodzi mwazovuta zazikulu za abiotic, kutsika kwa kutentha kumalepheretsa kukula kwa mbewu komanso kusokoneza zokolola ndi mtundu wa mbewu.5-Aminolevulinic acid (ALA) ndiyomwe imayambitsa kukula kwa nyama ndi zomera.Chifukwa chakuchita bwino kwambiri, kusakhala ndi kawopsedwe komanso kuwonongeka kosavuta, kumagwiritsidwa ntchito kwambiri pakulekerera kuzizira kwa zomera.
Komabe, kafukufuku waposachedwa wokhudzana ndi ALA makamaka amayang'ana kwambiri pakuwongolera ma endpoint network.Njira yeniyeni ya mamolekyu a zochita za ALA pakulekerera kuzizira koyambirira kwa zomera sikudziwika bwino ndipo imafuna kafukufuku wowonjezereka ndi asayansi.
Mu Januwale 2024, Horticultural Research idasindikiza pepala lofufuzira lotchedwa "5-Aminolevulinic Acid Imakulitsa Kulekerera Kuzizira mwa Kuwongolera SlMYB4/SlMYB88-SlGSTU43 Reactive Oxygen Species Scavenging Module in Tomato" ndi gulu la Hu Xiaohui ku Northwestern Agriculture ndi Forest University.
Mu phunziro ili, jini ya glutathione S-transferase SlGSTU43 inadziwika mu phwetekere (Solanum lycopersicum L.).Zotsatira za phunziroli zinawonetsa kuti ALA imapangitsa kuti SlGSTU43 iwonetsedwe pansi pa kupanikizika kozizira.Transgenic phwetekere mizere overexpressing SlGSTU43 anasonyeza kwambiri kuchuluka zotakasika zotakataka za oxygen mitundu scavenging mphamvu ndi anasonyeza kwambiri kukana kupanikizika otsika kutentha, pamene SlGSTU43 mutant mizere anali tcheru kutsika kutentha.
Kuphatikiza apo, zotsatira za kafukufuku zikuwonetsa kuti ALA sichikuwonjezera kulolerana kwa zovuta zosinthika mpaka kupsinjika kwa kutentha kochepa.Choncho, phunziroli likusonyeza kuti SlGSTU43 ndi jini yofunika kwambiri popititsa patsogolo kulekerera kuzizira mu phwetekere ndi ALA (Mkuyu 1).
Kuonjezera apo, phunziroli linatsimikiziridwa kudzera mu EMSA, Y1H, LUC ndi ChIP-qPCR kuzindikira kuti SlMYB4 ndi SlMYB88 akhoza kulamulira mawu a SlGSTU43 pomanga kwa SlGSTU43 wolimbikitsa.Kuyesera kwina kunasonyeza kuti SlMYB4 ndi SlMYB88 nawonso akugwira nawo ntchito ya ALC mwa kuwonjezera kulekerera kwa phwetekere kupsinjika kwa kutentha kochepa komanso kuwongolera bwino mawu a SlGSTU43 (mkuyu 2).Zotsatirazi zimapereka chidziwitso chatsopano cha njira yomwe ALA imakulitsa kulolerana ndi kutentha kochepa mu phwetekere.
Zambiri: Zhengda Zhang et al., 5-aminolevulinic acid imathandizira kulekerera kuzizira poyang'anira gawo la SlMYB4/SlMYB88-SlGSTU43 la mitundu yokhazikika ya okosijeni yomwe imasakaza mu phwetekere, Horticulture Research (2024).DOI: 10.1093/ola/uhae026
Ngati mukukumana ndi vuto, zolakwika, kapena mukufuna kutumiza pempho kuti musinthe zomwe zili patsambali, chonde gwiritsani ntchito fomuyi.Pamafunso ambiri, chonde gwiritsani ntchito fomu yathu yolumikizirana.Kuti mumve zambiri, chonde gwiritsani ntchito gawo lomwe lili pansipa (tsatirani malangizowo).
Ndemanga zanu ndi zofunika kwambiri kwa ife.Komabe, chifukwa cha kuchuluka kwa mauthenga, sitingatsimikizire kuyankha kwamunthu payekha.
Imelo yanu imangogwiritsidwa ntchito kuuza olandira omwe adatumiza imeloyo.Adilesi yanu kapena adilesi ya wolandila sizigwiritsidwa ntchito pazifukwa zina zilizonse.Zomwe mumalemba ziziwoneka mu imelo yanu ndipo sizisungidwa ndi Phys.org mwanjira iliyonse.
Landirani zosintha za sabata ndi/kapena zatsiku ndi tsiku mubokosi lanu.Mutha kusiya kulembetsa nthawi iliyonse ndipo sitidzagawana zambiri ndi anthu ena.
Timapangitsa kuti zinthu zathu zizipezeka kwa aliyense.Ganizirani kuthandizira ntchito ya Science X ndi akaunti yoyamba.
