Leha ho na le phapang liphatseng tsa lefutso lipakeng tsa lishaka le tuna, bo-rasaense ba fumane hore ka bobeli li na le litšobotsi tse tšoanang tsa lefutso la sebatli se seholo, ho kenyelletsa le lebelo le leholo la ho sisinyeha metsing le metabolism e potlakileng.
Leqepheng le phatlalalitsoeng koranteng ea Genome Biology and Evolution, boramahlale ba Borithane ba tlaleha hore tuna le mofuta oa shaka e kholo e tšoeu li tšoana ka tsela e makatsang, haholoholo mabapi le metabolism le bokhoni ba ho hlahisa mocheso. Bo-rasaense ba fihletse liqeto tse joalo ka ho hlahloba lisele tsa mesifa tse nkiloeng mefuteng e meraro ea lishaka le mefuta e tšeletseng ea tuna le mackerel.
Ka bobeli tuna le lishaka tse ithutoang li ne li na le 'mele le mehatla e thata, e li lumellang ho potlakisa ho phatloha. Ntle le moo, ba ka boloka mocheso oa 'mele ka nepo ha ba le metsing a batang. Litšobotsi tsena kaofela li etsa lishaka le li-tuna tse jang liphoofolo hantle hore li iphumanele lijo esita le metsing a sa pheleng hantle. Tuna e tsejoa e le setsomi se nang le tsebo bakeng sa litlhapi tse ling tse potlakileng, ha shaka e tšoeu e tsebahala e le setsomi se matla se khonang ho tsoma hoo e ka bang ntho e ngoe le e ngoe ho tloha ho litlhapi tse kholo ho isa ho liqibi.
Lefu lena le bitsoa GLYG1, 'me le fumanoe ka har'a lishaka le tuna,' me le hokahantsoe le metabolism le bokhoni ba ho hlahisa mocheso, e leng ntho ea bohlokoa bakeng sa liphoofolo tse jang liphoofolo tse tsomang phofu e joalo. Ntle le moo, bafuputsi ba fumane hore liphatsa tsa lefutso tse amanang le litšoaneleho tsena ke senotlolo sa khetho ea tlhaho mme li fetisetsa bokhoni bona ho meloko eohle e latelang ea tuna le lishaka. Tlhahlobo ea liphatsa tsa lefutso e bontšitse hore mefuta e 'meli ea liphoofolo e fumane litšobotsi tse ts'oanang molemong oa phetoho ea phetoho, ke hore, ka boikemelo e mong ho e mong.
Ho sibolloa hona ho ka thusa ho utloisisa kamano lipakeng tsa liphatsa tsa lefutso le litšobotsi tsa 'mele. Ebile, ho tloha qalong ena, thuto e kholo ea metheo ea liphatsa tsa lefutso kamanong le litšobotsi tsa 'mele le phetoho e fetohang e ka qala.
