Itsinda ry’ubushakashatsi riyobowe na RIKEN ryavumbuye ikintu gishobora gukoreshwa mu kuzamura intungamubiri z’ibihingwa.Abatwara ibintu bifitanye isano no kumanuka kumizi yibimera kubera uburemere.Iyi phenomenon yitwa umuzi geotropism1.googletag.cmd.push (imikorere () {googletag.ikinamico ('div-gpt-ad-1449240174198-2 ′);});
Charles Darwin yari umwe mu bahanga ba mbere bakoze ubushakashatsi ku buremere bw'imizi y'ibimera.Binyuze mu bushakashatsi bworoshye ariko bwiza, Darwin yerekanye ko imizi y’ibiti ishobora kumva uburemere, kandi ishobora kohereza ibimenyetso mu ngingo zegeranye, bityo igahindura imizi yerekeza ku rukuruzi.Ubu tumenye ko imisemburo ya hormone auxin igira uruhare runini muriki gisubizo gikurura imbaraga.
Imisemburo yibimera ifite imikorere myinshi yumubiri kandi irashobora gufasha ibimera kurwanya ihindagurika ryibidukikije.Kugirango ikore neza, ikwirakwizwa ryayo nibikorwa muri selile nuduce bigomba kuba byateguwe neza.Ubusanzwe harimo abatwara abantu bahuza ingirabuzimafatizo cyangwa kohereza imisemburo cyangwa abayibanjirije.
Noneho, abahanga mu binyabuzima ba RIKEN berekanye ko abatwara NPF7.3 bavuzwe haruguru bashobora kugenga igisubizo cya auxin hamwe nuburemere bwimizi mu gihingwa cy’icyitegererezo Arabidopsis.
Mitsunori Seo wo mu kigo cy’ubumenyi cya RIKEN kirambye yagize ati: “Twabonye ko ingemwe zifite ihinduka ry’imiterere ya gene irimo NPF7.3 zerekanye imikurire idasanzwe.”“Ubushakashatsi bwakozwe neza bwerekanye inenge yihariye yo gukurura imbaraga, nk'uko byavuzwe mbere.Imikorere ya NPF7.3 nka nitrate na transport ya potasiyumu ntishobora gusobanurwa.Ibi bituma dukeka ko poroteyine ishobora no kuba ifite indi mirimo idasanzwe. ”
Ubushakashatsi bwakurikiyeho bwerekanye ko NPF7.3 ikora nka transport ya acide indole-3-butyric (IBA), naho IBA yakiriwe ningirabuzimafatizo yihariye ikoresheje NPF7.3 ihinduka aside indole-3-acetike (IAA), ari yo nyamukuru imbere Inkomoko auxin.Ibi bifasha gushiraho auxin gradient mumitsi yumubiri, nayo ikayobora igisubizo cya rukuruzi.
IBA ni integuza ya kabiri ya IAA, kandi uruhare rwa IAA rukomoka kuri IBA mu rukuruzi rukuruzi ntirwari ruzwi.Nyamara, birasa nkaho ibindi bimera (harimo nubwoko bwibihingwa) nabyo bifite uburyo bumwe bwo kugenzura, bushobora kuganisha ku buhinzi n’imboga.
Seo yagize ati: "Tuzashobora guhindura imiterere ya sisitemu y'imizi tugenga ihererekanyabubasha rya IBA."Ati: “Ibi bizamura amazi n'intungamubiri binyuze mu mizi, bityo biteze imbere umusaruro w'ibihingwa.”
Intungamubiri za NPF zamenyekanye nka nitrate cyangwa peptide zitwara abantu, ariko biragaragara ko zihuza cyane kuruta uko twabitekerezaga.Seo yabisobanuye agira ati: “Ubushakashatsi buherutse gukorwa, harimo n'ubu, bwerekanye ko uyu muryango utwara abantu ushobora gutanga ibintu bitandukanye birimo imisemburo y'ibimera na metabolite ya kabiri.”Ati: “Ikibazo gikomeye gikurikiraho, turashaka kumenya uko poroteyine ya NPF ibimenya.Inzira nyinshi. ”
