Bafuputsi ba sibolotse kamoo limela li laolang liprotheine tsa DELLA kateng

Bafuputsi ba Lefapha la Biochemistry ho Indian Institute of Sciences (IISc) ba sibolotse mokhoa o 'nileng oa batloa ka nako e telele oa ho laola kholo ea limela tsa khale tsa naha tse kang bryophytes (sehlopha se kenyeletsang mosses le liverworts) tse ileng tsa bolokoa limela tse thunyang hamorao.
Phuputso ena, e phatlalalitsoeng koranteng ea Nature Chemical Biology, e shebane le taolo e seng ea molao ea liprotheine tsa DELLA, e leng molaoli ea ka sehloohong oa kholo ea lisele o thibelang karohano ea lisele ho li-embryophyte (limela tsa naha).
Hoa thahasellisa hore li-bryophyte, e leng limela tsa pele tse ileng tsa hlaha mobung lilemong tse ka bang limilione tse 500 tse fetileng, ha li na receptor ea GID1 leha li hlahisa phytohormone GA. Sena se hlahisa potso ea hore na kholo le nts'etsopele ea limela tsena tsa pele tsa mobu li ne li laoloa joang.
Ba sebelisa liverwort Marchantia polymorpha e le mokhoa oa mohlala, bafuputsi ba fumane hore limela tsena tsa khale li sebelisa enzyme e khethehileng, MpVIH, e hlahisang sele ea messenger inositol pyrophosphate (InsP₈), e li lumellang ho qhaqha DELLA ntle le tlhoko ea gibberellic acid.
Bafuputsi ba fumane hore DELLA ke e 'ngoe ea lipheo tsa sele tsa VIH kinase. Ho feta moo, ba hlokometse hore limela tse se nang MpVIH li etsisa li-phenotype tsa limela tsa M. polymorpha tse hlahisang DELLA ka bongata.
“Ntlheng ena, re ne re thabetse ho utloisisa hore na botsitso kapa ts'ebetso ea DELLA e eketsoa limela tse haelloang ke MpVIH,” ho boletse Priyanshi Rana, mongoli oa pele le seithuti se fumaneng mangolo sehlopheng sa lipatlisiso sa Lahey. Tumellanong le khopolo-taba ea bona, bafuputsi ba fumane hore ho thibela DELLA ho pholositse haholo kholo le nts'etsopele e nang le sekoli ea limela tse fetotsoeng tsa MpVIH. Liphetho tsena li bontša hore VIH kinase e laola DELLA hampe, ka hona e khothalletsa kholo le nts'etsopele ea limela.
Diphuputso mabapi le diprotheine tsa DELLA di simolohile Phetohelong e Tala, moo bo-rasaense ba neng ba sebedisa bokgoni ba bona ba ho hlahisa mefuta e fapaneng ya dimela tse nyane tse hlahisang chai e ngata. Le hoja dintlha tsa hore na di ne di sebetsa jwang di ne di sa hlaka ka nako eo, theknoloji ya sejwalejwale e dumella bo-rasaense ho laola mesebetsi ya diprotheine tsena ka boenjiniere ba dijini, e leng se etsang hore chai ya dijalo e be matla.
Ho ithuta limela tsa pele tsa naha ho boetse ho fana ka temohisiso mabapi le phetoho ea tsona lilemong tse limilione tse 500 tse fetileng. Mohlala, leha limela tsa lipalesa tsa sejoale-joale li sitisa liprotheine tsa DELLA ka mokhoa o itšetlehileng ka gibberellic acid, libaka tsa ho tlama tsa InsP₈ lia bolokoa. Liphuputso tsena li fana ka temohisiso mabapi le phetoho ea litsela tsa ho supa lisele ha nako e ntse e ea.
Sengoloa sena se hatisitsoe hape ho tsoa mehloling e latelang. Hlokomela: Mongolo o ka hlophisoa bakeng sa bolelele le litaba. Bakeng sa tlhaiso-leseling e batsi, ka kopo ikopanye le mohloli. Leano la rona la phatlalatso ea boralitaba le ka fumanoa mona.
