Mphere wamba ndi vuto lomwe limapitilira paulimi wa mbatata, lomwe limakhudza osati kukongola kwa ma tubers okha komanso mtengo wake wamsika. Matendawa, omwe amabweretsa zotupa za bulauni ngati nkhanambo pamwamba pa mbatata, zimayamba ndi gulu la mabakiteriya otchedwa Kuchiritsa, amene mwachibadwa amakhala m’nthaka. Ngakhale mbatata ikadali yotetezeka kudyedwa, zotupazo zimatsitsa mtundu wake, zomwe zimapangitsa kuti asafunike kugulitsidwa m'misika yatsopano, kupanga mbewu, ndi kukonza. Zikavuta kwambiri, kuwonongeka kumakhala kwakukulu kwambiri moti alimi amavutika kuti agulitse mbewu zawo.
Dr. Dawn Bignell, wofufuza pa Dipatimenti ya Biology ya Memorial University, akutsogolera gulu lomwe likufufuza zomwe zimayambitsa ndi mamolekyu omwe amachititsa nkhanambo. Kafukufukuyu, wothandizidwa ndi thandizo la $240,000 kuchokera ku Natural Sciences and Engineering Research Council (NSERC), akufuna kumvetsetsa bwino momwe Kuchiritsa mabakiteriya amapatsira mbatata ndikupanga mamolekyu oopsa omwe amayambitsa zilondazo.
"Nkhana yamba imapezeka m'madera ambiri omwe amalima mbatata ku Canada, ndipo njira zoyendetsera matenda zomwe zikugwiritsidwa ntchito panopa ndizosagwira ntchito kapena zosagwira ntchito," adatero Dr. Bignell. Kafukufuku wa gululi amayang'ana mamolekyu ang'onoang'ono opangidwa ndi tizilombo toyambitsa matenda omwe ali ndi poizoni kwa zomera, kuphunzira momwe mamolekyuwa amathandizira pakukula kwa matenda komanso momwe kupanga kwawo kumayendera mabakiteriya.
Vuto lalikulu pakuwongolera nkhanambo wamba ndiloti matendawa amayamba chifukwa chamitundu yosiyanasiyana Kuchiritsa mitundu yomwe imapezeka mwachilengedwe m'nthaka. Mabakiteriyawa amatha kuchita bwino m'malo osiyanasiyana, zomwe zimapangitsa kuti alimi azitha kulosera ndikuwongolera miliri. Njira zamakono zothanirana ndi nkhanambo, monga kasinthasintha wa mbeu kapena kugwiritsa ntchito mitundu ya mbatata yosamva mphamvu, zakhala zosagwirizana, zomwe zikusiya alimi alibe njira zothetsera.
Kupyolera mu kafukufuku wothandizidwa ndi NSERC, Dr. Bignell ndi gulu lake akupita patsogolo kwambiri pomvetsetsa zomwe zimayambitsa matendawa. Iwo akuyembekeza kuti kafukufukuyu apangitsa kuti pakhale njira zatsopano zothanirana ndi matenda zomwe zingachepetse mavuto azachuma omwe amabwera chifukwa cha nkhanambo kwa opanga mbatata ku Canada komanso padziko lonse lapansi.
Kuphatikiza apo, kafukufukuyu amapereka mwayi wofunikira pakukhudzidwa kwa ophunzira. Dr. Bignell akunena kuti ntchitoyi idzalola ophunzira omwe ali ndi maphunziro apamwamba komanso omaliza maphunziro awo kuti aphunzire luso la sayansi ya ma molekyulu, microbiology, biochemistry, ndi bioinformatics. Ophunzirawa adzakhalanso ndi luso lofunika kwambiri pa kayendetsedwe ka polojekiti, kulingalira mozama, ndi kugwira ntchito limodzi, zonse zomwe ziri zofunika kwambiri pa ntchito zawo zamtsogolo zaulimi ndi zina zasayansi.
"Ndalama zomwe talandira zitithandiza kufufuza momwe poizoni amapangidwira Kuchiritsa zimathandizira pakukula kwa matenda komanso momwe tingathandizire kupanga kwawo, "adatero Dr. Bignell. "Tikuyembekeza kuti chidziwitsochi chithandiza kupanga njira zatsopano zothanirana ndi matenda zomwe zingathandize alimi a mbatata kuti achepetse kuwonongeka ndikuwongolera mbewu."
Kafukufuku yemwe akuchitika ku Memorial University ndi njira yabwino yolimbana ndi nkhanambo wamba mu mbatata. Povumbula njira zama cell zomwe zimayambitsa matendawa ndi zotsatira zake zapoizoni, Dr. Bignell ndi gulu lake akuyala maziko a njira zothandizira komanso zokhazikika zoyendetsera matenda. Kupita patsogolo kumeneku sikungathe kupititsa patsogolo ulimi wa mbatata ku Canada komanso kungapereke chidziwitso chofunikira kwa alimi a mbatata padziko lonse lapansi, zomwe zimathandizira kuteteza tsogolo la kulima mbatata.
