I-γ-Valactone ikhuthaza ukukhula kwezithole zetamatato ngokutshintsha i-transcriptome kunye ne-hormone yezityalo | I-Plant Molecular Biology

Ukunciphisa ukuxhomekeka kwezolimo kwizichumisi zeekhemikhali, umdla kwiintlobo ezintsha zezichumisi uyanda.abakhuthazi bokukhula abathembisayo.IGamma-valactone, ikhompawundi yendalo eguquguqukayo eveliswa yi *S. stearothermiae* NRCB010, ibonakalisiwe ukuba ikhuthaza ukukhula kwezithole zetamatato phantsi kweemeko ezingenakubola. Ke ngoko, siphande imiphumo yoxinzelelo olwahlukeneyo lwegamma-valactone ekukhuleni kwezithole zetamatato phantsi kweemeko zehydroponic kunye negreenhouse, saza sahlola notshintsho oluhambelanayo kumanqanaba okubhalwa kunye namahomoni. Iziphumo zibonise ukuba unyango lwegamma-valactone lukhuthaze kakhulu ukukhula kwezithole zetamatato, kunye noxinzelelo olufanelekileyo lwe-100 mg/L kunye ne-250 mg/L phantsi kweemeko zehydroponic kunye negreenhouse, ngokwahlukeneyo. Umxholo we-IAA-aspartic acid, i-IAA-glutamic acid,i-indole-3-acetamide, i-indole-3-acetonitrile, i-indole-3-butyric acid, kunye ne-gibberellin kumagqabi, iziqu, kunye neengcambu zande kakhulu. Uhlalutyo lweTranscriptome lubonise ukuba emva kweeyure ezi-6 zonyango lwe-γ-valerolactone, inani lee-genes ezichazwe ngokwahlukileyo (ii-DEG) ezinee-expression ezandisiweyo lidlule inani lee-genes ezinee-expression ezandisiweyo; nangona kunjalo, imeko echaseneyo yabonwa emva kweeyure ezingama-24 zonyango. I-γ-valerolactone inokukhuthaza ukukhula kwezithole zetamatato ngeendlela ezifana ne-photosynthesis, i-plant hormone signaling, kunye ne-secondary metabolite biosynthesis. Olu phononongo lubonelela ngesiseko sethiyori sokusetyenziswa kwe-γ-valerolactone njengomlawuli omtsha wokukhula kwezityalo kwaye lubeka isiseko sophuhliso lwe-biostimulants yezolimo esebenzayo kakhulu nenobuhlobo nokusingqongileyo.

Uhlalutyo lwe-morphological, transcriptomic kunye ne-hormone lubonise ukuba i-γ-valerolactone iphucula ukukhula kwezithole zetamatato kwaye inyusa amanqanaba e-hormone.
