Chinhu chinokatyamadza chakawanikwa muindasitiri yembatatisi. Sekutsvagurudza kuchangobva kuitika kwakabudiswa muThe Plant Cell, bhuku rine mukurumbira pasi rose resangano reAmerican Society of Plant Biologists, vaongorori vakadoma chidiki diki chinokonzeresa nyaya yekugadzira mbatatisi. Ichi chinhu, chakavigwa mukati meiyo mbatatisi vacuolar invertase gene, chakaonekwa sechikonzero che "cold-induced sweetening" (CIS), dambudziko guru kuindasitiri yekugadzira mbatatisi.
Chiitiko cheCIS chinomuka apo mbatatisi, chirimwa chekudya zvakanyanya pasi rose, inochengeterwa inotonhora, inowanzoitika kudzivirira zvirwere, kumera, uye kupfava. Nekudaro, tembiricha inotonhora inokonzeresa shanduko yestarch kuita shuga mukati memachubhu, zvichitungamira kune zvisingadiwe mhedzisiro sekugadzirwa kweacrylamide uye isingafadzike yakasviba-yakasviba ruvara kana mbatatisi yakakangwa mushure mekubviswa mudura.
Chidzidzo ichi chakafumura DNA motifs mukati meiyo 200-bp inoteedzana inosungirira kune zvinyorwa zvinosanganisirwa mukupindura kwechirimwa kune inotonhora kusagadzikana. Nekushandura aya akateedzana, vaongorori vakacherekedza kudzikiswa kwakanyanya mukutonhora-kushushikana kupindura mumatato.
Ichi chakazarurwa chinokatyamadza hachingotauri nezvenyaya yekurima kwenguva refu asi zvakare inovhura nzira yekuvandudzwa kunogona kuitika kuburikidza nekugadzirisa magene. Jiming Jiang, Munyori Anowirirana Wechidzidzo ichi, akasimbisa kukosha kwekuwanikwa uku uye kurongeka kwayo nezvinangwa zvechirongwa chekupfuya mbatatisi kuDhipatimendi reHorticulture, University of Wisconsin-Madison.
Zvakawanikwa muchidzidzo ichi zvine vimbiso yekuvandudza kugadzirwa nekugadzirisa mbatatisi, zvichipa mhinduro kumatambudziko anokonzerwa nekutonhora-inotapira, uye kuvhura nzira nyowani dzekusimudzira kunaka uye kusimba kwekurima mbatatisi.
