Seimwe yematambudziko makuru ekusadya zvirimwa, kushushikana pakupisa kushoma kunokanganisa kukura kwezvirimwa zvakanyanya uye kunokanganisa goho uye kunaka kwezvirimwa. 5-Aminolevulinic acid (ALA) inodzora kukura kwezvirimwa zvakanyanya mumhuka nezvirimwa. Nekuda kwekushanda kwayo kwakanyanya, kusakuvadza uye nyore kuiparadza, inoshandiswa zvakanyanya mukurwisa kutonhora kwezvirimwa.
Zvisinei, tsvakiridzo zhinji dziripo dzeALA dzinonyanya kutarisa pakugadzirisa ma network endpoints. Maitiro chaiwo e ALA ekuita mukukura kwemiti mukupisa kwechando haasati ajeka uye anoda kuti masayendisiti atsvage zvakanyanya.
Muna Ndira 2024, Horticultural Research yakaburitsa bepa rekutsvagisa rine musoro unoti “5-Aminolevulinic Acid Inosimudzira Kushivirira Kutonhora Nekudzora SlMYB4/SlMYB88-SlGSTU43 Reactive Oxygen Species Scavenging Module muTomato” rakanyorwa nechikwata chaHu Xiaohui paNorthwestern University agriculture and forestry.
Muchidzidzo ichi, jini reglutathione S-transferase SlGSTU43 rakaonekwa mumatomatisi (Solanum lycopersicum L.). Zvakabuda muchidzidzo ichi zvakaratidza kuti ALA inokurudzira zvikuru kuratidzwa kweSlGSTU43 pasi pekumanikidzwa nechando. Transgenic tomato lines SlGSTU43 yakaratidza kuwedzera kwakanyanya kwe reactive oxygen species uye yakaratidza kuramba kwakanyanya kumanikidzwa nekupisa kwakaderera, nepo SlGSTU43 mutant lines yainzwa kumanikidzwa nekupisa kwakaderera.
Pamusoro pezvo, mhedzisiro yekutsvagisa yakaratidza kuti ALA haiwedzere kushivirira kwemhando yemutant kusvika pakupisa kwakaderera. Saka, chidzidzo ichi chinoratidza kuti SlGSTU43 ijini rakakosha mukusimudzira kushivirira kutonhora mumatomatisi neALA (Mufananidzo 1).
Pamusoro pezvo, chidzidzo ichi chakasimbisa kuburikidza nekuona kweEMSA, Y1H, LUC uye ChIP-qPCR kuti SlMYB4 neSlMYB88 zvinogona kudzora kuratidzwa kweSlGSTU43 nekusunga kune SlGSTU43 promoter. Kumwe kuyedza kwakaratidza kuti SlMYB4 neSlMYB88 zvine chekuitawo nemaitiro eALC nekuwedzera kushivirira kwematomatisi kusvika pakumanikidzwa kwakaderera uye kudzora kuratidzwa kweSlGSTU43 zvakanaka (Mufananidzo 2). Mhedzisiro iyi inopa nzwisiso itsva pamusoro penzira iyo ALA inowedzera kushivirira kushushikana kwakaderera kwematomatisi.

Kana mukasangana nezvikanganiso zvisirizvo, kusarongeka, kana kuti muchida kutumira chikumbiro chekugadzirisa zviri papeji rino, ndapota shandisai fomu iri. Kana muine mibvunzo yakawanda, ndapota shandisai fomu redu rekutaurirana. Kuti muwane mhinduro dzakawanda, ndapota shandisai chikamu chemashoko everuzhinji chiri pazasi (teverai gwara).
Mhinduro dzenyu dzakakosha zvikuru kwatiri. Zvisinei, nekuda kwekuwanda kwemashoko, hatigone kuvimbisa mhinduro yakanangana nesu.
