Abstract
The transition from vegetative to reproductive growth in perennial woody plants does not occur until after several years of repeated seasonal changes and alternative growth. To better understand the molecular basis of flowering regulation in citrus, a MADS-box gene was isolated from trifoliate orange (precocious trifoliate orange,

To better understand the molecular basis of flowering regulation in citrus, a MADS-box gene was isolated from trifoliate orange (precocious trifoliate orange, <italic>Poncirus trifoliata</italic> L. Raf.). Sequence alignment and phylogenetic analysis showed that the MADS-box gene is more closely related to the homologs of the <italic>AGAMOUS-LIKE 24</italic> (<italic>AGL24</italic>) lineage than to any of the other MADS-box lineages known from <italic>Arabidopsis</italic>; it is named <italic>PtAGL24</italic>. Expression analysis indicated that <italic>PtAGL24</italic> was widely expressed in the most organs of trifoliate orange, with the higher expression in mature flowers discovered by real-time PCR. Ectopic expression of <italic>PtAGL24</italic> in wild-type <italic>Arabidopsis</italic> promoted early flowering and caused morphological changes in class I transgenic <italic>Arabidopsis</italic>. Yeast two-hybrid assay revealed that PtAGL24 interacted with <italic>Arabidopsis</italic> AtAGL24 and other partners of AtAGL24, suggesting that the abnormal morphology of <italic>PtAGL24</italic> overexpression in transgenic <italic>Arabidopsis</italic> was likely due to the inappropriate interactions between exogenous and endogenous proteins. Also, PtAGL24 interacted with SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (PtSOC1) and APETALA1 (PtAP1) of citrus. These results suggest that <italic>PtAGL24</italic> may play an important role in the process of floral transition but may have diverse functions in citrus development.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Becker, A" uniqKey="Becker A">A.

To better understand the molecular basis of flowering regulation in citrus, a MADS-box gene was isolated from trifoliate orange (precocious trifoliate orange, <italic>Poncirus trifoliata</italic> L. Raf.). Sequence alignment and phylogenetic analysis showed that the MADS-box gene is more closely related to the homologs of the <italic>AGAMOUS-LIKE 24</italic> (<italic>AGL24</italic>) lineage than to any of the other MADS-box lineages known from <italic>Arabidopsis</italic>; it is named <italic>PtAGL24</italic>. Expression analysis indicated that <italic>PtAGL24</italic> was widely expressed in the most organs of trifoliate orange, with the higher expression in mature flowers discovered by real-time PCR. Ectopic expression of <italic>PtAGL24</italic> in wild-type <italic>Arabidopsis</italic> promoted early flowering and caused morphological changes in class I transgenic <italic>Arabidopsis</italic>. Yeast two-hybrid assay revealed that PtAGL24 interacted with <italic>Arabidopsis</italic> AtAGL24 and other partners of AtAGL24, suggesting that the abnormal morphology of <italic>PtAGL24</italic> overexpression in transgenic <italic>Arabidopsis</italic> was likely due to the inappropriate interactions between exogenous and endogenous proteins. Also, PtAGL24 interacted with SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (PtSOC1) and APETALA1 (PtAP1) of citrus. These results suggest that <italic>PtAGL24</italic> may play an important role in the process of floral transition but may have diverse functions in citrus development.</p></abstract><kwd-group><kwd>flowering</kwd><kwd>floral development</kwd><kwd>MADS-box</kwd><kwd>trifoliate orange</kwd><kwd><italic>PtAGL24</italic></kwd></kwd-group><counts><fig-count count="6"></fig-count><table-count count="2"></table-count><equation-count count="0"></equation-count><ref-count count="40"></ref-count><page-count count="12"></page-count><word-count count="0"></word-count></counts></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
