[ Sen. 4, subscore: 1.00 ]: Two of these , Oskn2 and Oskn3 , encode newly described KNOX genes , whereas the third ( Oskn1 ) corresponds to the previously described OSH1 gene .
[ Sen. 6, subscore: 1.00 ]: Whereas OSH1 was previously proposed to function also in SAM maintenance , Oskn3 may be involved in patterning organ positions , as its expression was found to mark the boundaries of different embryonic organs following SAM formation .
[ Sen. 8, subscore: 1.00 ]: Transgenic expression of Oskn2 and Oskn3 in tobacco further supported their involvement in cell fate determination , like previously reported for Knotted1 and OSH1 ectopic expression .

[ Sen. 9, subscore: 3.00 ]: An in situ hybridization experiment using a rice homeobox gene , OSH1 , as a probe revealed that shl1 and shl2 modified the expression domain of OSH1 , but normal expression of OSH1 was observed in shl3 and shl4 embryos .
[ Sen. 10, subscore: 2.00 ]: Accordingly , SHL1 and SHL2 function upstream of OSH1 , and SHL3 and SHL4 downstream or independently of OSH1 .

[ Sen. 6, subscore: 1.00 ]: Rapid and random leaf production in sho mutants is correlated with the frequent and disorganized cell divisions in the shoot meristem and with a reduction of expression domain of a rice homeobox gene , OSH1 .

| Title: KNOX homeobox genes are sufficient in maintaining cultured cells in an undifferentiated state in rice .

[ Sen. 1, subscore: 3.00 ]: We produced transgenic rice calli , which constitutively express each of four KNOX family class 1 homeobox genes of rice , OSH1 , OSH16 , OSH15 , and OSH71 , and found that constitutive and ectopic expression of such genes inhibits normal regeneration from transformed calli , which showed continuous growth around their shoot-regenerating stages .
[ Sen. 3, subscore: 1.00 ]: In the normal shoot-regeneration process of calli , expression of endogenous OSH1 was restricted in presumptive shoot-regenerating regions of calli and not observed in other areas .

| Title: Functional analysis of the conserved domains of a rice KNOX homeodomain protein , OSH15 .

[ Sen. 1, subscore: 1.00 ]: The rice KNOX protein OSH15 consists of four conserved domains : the MEINOX domain , which can be divided into two subdomains ( KNOX1 and KNOX2 ) ; the GSE domain ; the ELK domain ; and the homeodomain ( HD ) .
[ Sen. 4, subscore: 1.00 ]: We also found that both KNOX2 and HD are necessary for homodimerization and that only HD is needed for binding of OSH15 to its target sequence .
[ Sen. 6, subscore: 1.00 ]: On the basis of these findings , we propose that overproduced OSH15 probably acts as a dimer and may ectopically suppress the expression of target genes that induce abnormal morphology in transgenic plants .

[ Sen. 8, subscore: 1.00 ]: In shl2 mutants , there was a positive correlation between the size of the expression domain of OSH1 representing the number of indeterminate cells , the frequency of shoot meristem initiation , and the duration of meristem survival Thus the shoot meristem will not initiate in an "all-or-nothing" fashion , but is formed in various degrees depending on the strength of the alleles .

[ Sen. 4, subscore: 1.00 ]: We developed two markers specifically staining the L2 and L3 layers ( OsSCR and OsPNH1 , respectively ) and characterized the gle mutants by using these markers in addition to the already developed markers Roc1 ( marker for the L1 layer ) , Ramy1A ( marker of the L1 layer of the epithelium ) , and OSH1 ( marker of the apical region ) .
[ Sen. 5, subscore: 1.00 ]: One of the gle mutants , gle4 , expressed Roc1 and Ramy1A at the normal positions , but other markers exhibited an abnormal expression pattern ; that is , both OsPNH1 and OsSCR were expressed in the central region of the embryo and OSH1 expression was not observed .
