Abstract:To further analyze the regulation mechanism of γ -gliadingeneinflourqualityofwheat,the Tagli-y-11 gene wassucesfullycloned from Zhengmai158(low proteincontent and high dough strength).Bioinformatic analysis revealed that this gene possessed the typical structural characteristicsof γ -gliadin,containing eight conserved cysteine residues.Aceliac disease(CD)epitope(PQQSFPQQQ)was identified withinrepeatdomainIof the Tagli-y-11 protein,
located at amino acid positions 133-141 . Using the yeast two-hybrid(Y2H)system,thecDNAlibraryofZhengmai 158 was screened,yielding eight candidate proteins potentiallyinteractingwithTagli- γ -11.These included cysteine protease,fructose-bisphosphatealdolase,cysteine-rich and transmembrane domain-containing protein1,(1,3: 1,4)-β-D-glucanase,auxinresponse factor 17-like (ARF17-like),cell number regulator 8-like (CNR8- like),ubiquitin-associated domain-containing protein
DSK2b,transcription factor PIF1-like.Therotation validationassays performedoncysteine-rich and transmembrane domain-containing protein1,fructose-bisphosphate aldolase,and ( 1,3:1,4) -β-D-glucanase confirmed physical interaction withTagli- γ -11.Based on these results,itwashypothesized that Tagli γ -11interacted with theseproteinsand participated in the synthesis and degradation of storage proteins (such as gliadin)and starch within wheat grains,as wellas inreproductive growth processes.
