Tetezani ndikukulitsa: Chinyengo chokulitsa zakudya zambiri

Kuchuluka kwathu kwa anthu si nthabwala. Malinga ndi Bill Gates, Chiwerengero cha anthu padziko lonse lapansi chikuyembekezeka kufika 9 biliyoni pofika chaka cha 2050. Kuti apitirize kudyetsa anthu 9 biliyoni, kupanga chakudya kuyenera kuwonjezeka ndi 70-100%. Alimi ayamba kale kubzala mbewu zawo mochuluka kuti abereke chakudya chochuluka, koma mbewu zobzalidwa mochuluka zimakopabe mavuto. 

Nthawi Yoyenera Kukula, Nthawi Yoyenera Kuteteza 

Zomera zimakhala ndi mphamvu zochepa zogwiritsira ntchito nthawi imodzi; akhoza kukula kapena kudziteteza, koma sangathe kutero nthawi imodzi. M'mikhalidwe yabwino, chomera chimakula pamlingo woyenera; koma, pamene kulimbikitsidwa ndi chilala, matenda kapena tizilombo, zomera zimayankha modzitchinjiriza, mwina kuchedwetsa kapena kuletsa kukula palimodzi. Akafuna kukula mofulumira monga pamene akupikisana ndi zomera zoyandikana nawo kuti apeze kuwala (kuyankha kwa mthunzi), amasiya chitetezo chawo kuti agwiritse ntchito mphamvu zawo zonse kuti akule. Komabe, ngakhale zitakula msanga, mbewu zobzalidwa kwambiri zimakhala zosatetezeka ku tizirombo. 
 

Gulu la ofufuza ku Michigan State University posachedwapa wapeza njira kuzungulira kukula-chitetezo malonda. Zasindikizidwa posachedwa mu Nature Kulumikizana, gulu likufotokoza momwe angasinthire chibadwa chomera kuti chipitirize kukula pamene chimadziteteza ku mphamvu zakunja. Gulu la asayansi lidazindikira kuti chopondera chodzitetezera cha chomeracho ndi cholandirira chopepuka chikhoza kudodometsedwa pamayankhidwe a mmerawo. 
 

Gulu lofufuza linagwira ntchito ndi chomera cha Arabidopsis (mofanana ndi mpiru), koma njira yawo ingagwiritsidwe ntchito pa zomera zonse. Pulofesa Gregg Howe, katswiri wa biochemist ndi molecular biologist wa MSU Foundation, anatsogolera kafukufukuyu ndipo anafotokoza kuti "mahomoni ndi njira zoyankhira zopepuka [zomwe] zinasinthidwa zili m'mbewu zonse zazikulu."
