| Title: Functional analysis of all AGAMOUS subfamily members in rice reveals their roles in reproductive organ identity determination and meristem determinacy .
| | Author: Dreni L Pilatone A Yun D Erreni S Pajoro A Caporali E Zhang D Kater MM | | Journal: Plant Cell Citation: V : 23 P : 2850-63 Year: 2011 Type: In-Process | | Literature: oryza Field: abstract Doc ID: pub21810995 Accession (PMID): 21810995 | | Abstract: Reproductive organ development is one of the most important steps in the life cycle of plants .
Studies using core eudicot species like thale cress ( Arabidopsis thaliana ) and snapdragon ( Antirrhinum majus ) have shown that MADS domain transcription factors belonging to the AGAMOUS ( AG ) subfamily regulate the identity of stamens , carpels , and ovules and that they are important for floral meristem determinacy .
Here , we investigate the genetic interactions between the four rice ( Oryza sativa ) AG subfamily members , MADS3 , MADS13 , MADS21 , and MADS58 .
Our data show that , in contrast with previous reports , MADS3 and MADS58 determine stamen and carpel identity and , together with MADS13 , are important for floral meristem determinacy .
In the mads3 mads58 double mutant , we observed a complete loss of reproductive organ identity and massive accumulation of lodicules in the third and fourth floral whorls .
MADS21 is an AGL11 lineage gene whose expression is not restricted to ovules .
Instead , its expression profile is similar to those of class C genes .
However , our genetic analysis shows that MADS21 has no function in stamen , carpel , or ovule identity determination .

| Title: Rice MADS6 interacts with the floral homeotic genes SUPERWOMAN1 , MADS3 , MADS58 , MADS13 , and DROOPING LEAF in specifying floral organ identities and meristem fate .
| | Author: Li H Liang W Hu Y Zhu L Yin C Xu J Dreni L Kater MM Zhang D | | Journal: Plant Cell Citation: V : 23 P : 2536-52 Year: 2011 Type: In-Process | | Literature: oryza Field: abstract Doc ID: pub21784949 Accession (PMID): 21784949 | | Abstract: AGAMOUS-LIKE6 ( AGL6 ) genes play essential roles in flower development , but whether and how they work with floral organ identity genes remain less understood .
Here , we describe interactions of the rice ( Oryza sativa ) AGL6 gene MADS6 with other rice floral homeotic genes in flower development .
Genetic analyses revealed that MADS6 specifies the identity of the three inner whorls and floral meristem determinacy redundantly with SUPERWOMAN1/MADS16 ( B-gene ) or MADS3 ( C-gene ) .
MADS6 was shown to define carpel/ovule development and floral determinacy by interacting with MADS13 ( D-gene ) and control the palea and floral meristem identities together with the YABBY gene DROOPING LEAF .
Expression analyses revealed that the transcript levels of six B- , C- , and E-class genes were reduced in mads6-1 at the early flower developmental stage , suggesting that MADS6 is a key regulator of early flower development .
Moreover , MADS6 can directly bind to a putative regulatory motif on MADS58 ( C-gene ) , and mads6-1 mads58 displayed phenotypes similar to that of mads6-1 .
These results suggest that MADS6 is a key player in specifying flower development via interacting with other floral homeotic genes in rice , thus providing new insights into the mechanism by which flower development is controlled .
