Onye na-ahụ maka uto 5-aminolevulinic acid na-abawanye nguzogide oyi nke osisi tomato.

      Dị ka otu n'ime isi nrụgide abiotic, nrụgide okpomọkụ dị ala na-egbochi uto osisi ma na-emetụta mkpụrụ na ịdị mma nke ihe ọkụkụ.5-Aminolevulinic acid (ALA) bụ onye na-ahụ maka uto nke dị na anụmanụ na osisi.N'ihi arụmọrụ dị elu ya, adịghị egbu egbu na nbibi dị mfe, a na-eji ya eme ihe n'ọtụtụ ebe na usoro nke oyi na-atụ nke osisi.
Agbanyeghị, ọtụtụ nyocha ugbu a metụtara ALA na-elekwasị anya na ịhazi ebe njedebe netwọkụ.Usoro molekụla a kapịrị ọnụ nke omume ALA n'oge nnabata oyi nke osisi amabeghị ugbu a yana ọ chọrọ nyocha ọzọ site n'aka ndị sayensị.
Na Jenụwarị 2024, Horticultural Research bipụtara akwụkwọ nyocha nke isiokwu ya bụ "5-Aminolevulinic Acid na-eme ka oyiri oyi site na ịhazi SlMYB4/SlMYB88-SlGSTU43 Reactive Oxygen Species Scavenging Module na Tomato" nke Hu Xiaohui's team at Northwestern University
N'ime ọmụmụ ihe a, a chọpụtara glutathione S-transferase gene SlGSTU43 na tomato (Solanum lycopersicum L.).Nsonaazụ nke ọmụmụ ahụ gosiri na ALA na-akpalite okwu nke SlGSTU43 n'okpuru nrụgide oyi.Ahịrị tomato transgenic overexpressing SlGSTU43 gosipụtara ike na-eme ka ụdị oxygen na-arụ ọrụ nke ukwuu wee gosipụta oke nguzogide nrụgide dị ala, ebe ahịrị mutant SlGSTU43 nwere mmetụta maka nrụgide dị ala.
