 - Key message
    
- Unlike the Arabidopsis YABBY genes, however, the OsYAB1 gene does not show polar expression pattern in the tissues of floral organs
 - Our transgenic plants that ectopically expressed OsYAB1 were normal during the vegetative growth period, but then showed abnormalities in their floral structures
 - RNA gel-blot analysis showed that the OsYAB1 gene is preferentially expressed in flowers
 - OsYABBY1 is expressed in putative precursor cells of both the mestome sheath in the large vascular bundle and the abaxial sclerenchyma in the leaves
 - In the flower, OsYABBY1 is specifically expressed in the palea and lemma from their inception, and is confined to several cell layers of these organs in the later developmental stages
 - These results suggest that OsYAB1 plays a major role in meristem development and maintenance of stamens and carpels, rather than in determining polarity
 - Ectopic expression of OsYAB1 causes extra stamens and carpels in rice

- Oshox4, OsYABBY1~OsYAB1, Functional analysis of rice HOMEOBOX4 Oshox4 gene reveals a negative function in gibberellin responses, Interestingly, the expression of YAB1 that is involved in the negative feedback regulation of the GA biosynthesis was upregulated in the Oshox4 over-expressing plants
 - Oshox4, OsYABBY1~OsYAB1, Functional analysis of rice HOMEOBOX4 Oshox4 gene reveals a negative function in gibberellin responses, One-hybrid assays showed that Oshox4 could interact with YAB1 promoter in yeast
 - d18~OsGA3ox2, OsYABBY1~OsYAB1, The rice YABBY1 gene is involved in the feedback regulation of gibberellin metabolism, In this report, we show that a rice (Oryza sativa) YABBY1 (YAB1) gene had a similar expression pattern as key rice GA biosynthetic genes GA3ox2 and GA20ox2
 - d18~OsGA3ox2, OsYABBY1~OsYAB1, The rice YABBY1 gene is involved in the feedback regulation of gibberellin metabolism, Cosuppression of YAB1 in transgenic plants induced expression of GA3ox2
 - d18~OsGA3ox2, OsYABBY1~OsYAB1, The rice YABBY1 gene is involved in the feedback regulation of gibberellin metabolism, The repression of GA3ox2 could be obtained upon treatment by dexamethasone of transgenic plants expressing a YAB1-glucocorticoid receptor fusion
 - d18~OsGA3ox2, OsYABBY1~OsYAB1, The rice YABBY1 gene is involved in the feedback regulation of gibberellin metabolism, Importantly, we show that YAB1 bound to a GA-responsive element within the GA3ox2 promoter
 - d18~OsGA3ox2, OsYABBY1~OsYAB1, The rice YABBY1 gene is involved in the feedback regulation of gibberellin metabolism, Finally, either overexpression or cosuppression of YAB1 impaired GA-mediated repression of GA3ox2
 - OsYABBY1~OsYAB1, sd1~GA20ox2, The rice YABBY1 gene is involved in the feedback regulation of gibberellin metabolism, In this report, we show that a rice (Oryza sativa) YABBY1 (YAB1) gene had a similar expression pattern as key rice GA biosynthetic genes GA3ox2 and GA20ox2
