OsXTH8 was preferentially expressed in rice leaf sheath in response to gibberellic acid. OsXTH8 was highly expressed in vascular bundles of leaf sheath and young nodal roots where the cells are actively undergoing elongation and differentiation. OsXTH8 gene expression was up-regulated by gibberellic acid and there was very little effect of other hormones. Reduced accumulation of active GA was accompanied by preferential suppression of OsXTH8 expression, and OsXTH8 expression increased when exogenous GA3 was applied to the semidwarf mutant. In two genetic mutants of rice with abnormal height, the expression of OsXTH8 positively correlated with the height of the mutants. Transgenic rice expressing an RNAi construct of OsXTH8 exhibited repressed growth. These results indicate that OsXTH8 is differentially expressed in rice leaf sheath in relation to gibberellin and potentially involved in cell elongation processes.

To examine the tissue specificity of OsXTH8, total RNAs from rice callus, root, leaf blade, and leaf sheath were hybridized with OsXTH8-specific DNA probe. A strong signal was detected in leaf sheaths but weak or no signal was observed in leaf blades, roots, and calli (Fig. 4A). These expressions were enhanced by GA3 treatment (Fig. 4A). When 1-month-old seedlings were used to characterize the expression in leaf sheath, the expression was mainly found in the three basal parts of leaf sheath (Fig. 4B). Enhanced expression of OsXTH8 in the third part of 1-month-old rice seedling, which corresponded to the second internode of leaf sheath, compared to two basal parts of leaf sheath showed that OsXTH8 is differentially expressed in leaf sheath.

In situ hybridization was performed using the basal part (culm) of 2-week-old rice seedlings to learn more about the expression pattern. On hybridization with gene-specific OsXTH8 antisense probe, the cross and longitudinal sections of culm tissue revealed an accumulation of OsXTH8 mRNA in shoot apex meristem, vascular tissues, and young leaves (Fig. 5A). Although the expression did not seem to be delimited to specific cell types, significant hybridization was observed in large and small vascular bundles of leaf sheath and peripheral cylinder of the vascular bundles and fibers in the nodal region (Fig. 5A). No significant signal was visible when sense probe was used.

To further characterize the spatial distribution patterns of OsXTH8 gene expression, 2,325 bp of the OsXTH8 upstream region from the proposed first translational start site was fused to the β-glucuronidase (GUS) reporter gene. This fusion gene was introduced into rice cells, and transgenic plants were regenerated. Putative OsXTH8::GUS transgenic plants were screened by PCR. Only PCR-confirmed, transgenic lines were used for GUS staining and GUS assay. To assess whether the GUS staining patterns were consistent with the result of in situ hybridization, similartissue sections of leaf sheath were used. Figure 5Bshows the GUS expression pattern driven by OsXTH8 promoter in the basal part of leaf sheath and young nodal roots of 2-week-old rice seedlings. In the case of leaf sheath, strong GUS staining was observed in shoot apex meristem and vascular bundles, very much similar to the result of in situ hybridization (Fig. 5, A and B). Microscopic observation of vascular bundles revealed GUS expression in vascular bundle sheath and mesotomic sheath surrounding xylem and phloem. Stele or vascular cylinder region in young nodal roots of the coleoptile node and roots arising from nodal roots also showed GUS staining (Fig. 5B). Weak GUS staining was found in the sclerenchyma cells lining the epidermis of young leaves (Fig. 5B).

The analysis revealed that XTHs could be loosely grouped into four distinct groups (Fig. 3). Group 1 contains genes that share a high level of sequence identity among different species and that are expressed in young developing tissues. Group 2 comprises ''XTH'' genes from several species showing diverse patterns of expression and response to hormonal or mechanical stimuli, including touchinducible, flooding-response, BR-inducible, and fruit ripening-related ''XTHs''. Group 3 represents a divergent group of ''XTHs'', including ''NXG1'' from nasturtium (''Tropaeolum'' ''majus'') that can act as xyloglucan hydrolase and transglycosylase. OsXTH8 has the highest homology to sequences in Group 4, consisting of well-characterized barley (''Hordeum vulgare'') genes, ''HvPM2'' and ''HvPM5'',which are up-regulated by GA in barley leaf sheaths and leaves. Monocot members of group 4 revealed to have two substitutions (DEIDIEFMG) compared to the consensus sequence (DEIDFEFLG). The presence of different amino acid residues in the putative catalytic region may attribute to unique enzymatic activity of OsXTH8.

Expression

OsXTH8 was preferentially expressed in rice leaf sheath in response to gibberellic acid. OsXTH8 was highly expressed in vascular bundles of leaf sheath and young nodal roots where the cells are actively undergoing elongation and differentiation. OsXTH8 gene expression was up-regulated by gibberellic acid and there was very little effect of other hormones.Reduced accumulation of active GA was accompanied by preferential suppression of OsXTH8 expression, and OsXTH8 expression increased when exogenous GA3 was applied to the semidwarf mutant.

Transgenic rice expressing an RNAi construct of OsXTH8 exhibited repressed growth. These results indicate that OsXTH8 is differentially expressed in rice leaf sheath in relation to gibberellin and potentially involved in cell elongation processes.

OsXTH8 was expressed in growing regions such as shoot apical meristem, vascular bundles of leaf sheath, and young crown roots developing from nodes; thus, OsXTH8 exhibited a unique expression pattern in terms of organ and stage specificity during leaf sheath elongation and young nodal root development. The expression of OsXTH8 in the shoot apex meristem, vascular bundles in leaf sheath, and youngnodal roots supports its role in cell wall modification processes during active growth[1].

Alternative Organ- and Cell Type-Expression Profiles of OsXTH8

It has been shown that different members of XTH gene family are specifically regulated by various physiological and environmental stimuli[2].To examine the tissue specificity of OsXTH8, total RNAs from rice callus, root, leaf blade, and leaf sheath were hybridized with OsXTH8-specific DNA probe. A strong signal was detected in leaf sheaths but weak or no signal was observed in leaf blades, roots, and calli (Fig. 4A). These expressions were enhanced by GA3 treatment (Fig. 4A). When 1-month-old seedlings were used to characterize the expression in leaf sheath, the expression was mainly found in the three basal parts of leaf sheath (Fig. 4B). Enhanced expression of OsXTH8 in the third part of 1-month-old rice seedling, which corresponded to the second internode of leaf sheath, compared to two basal parts of leaf sheath showed that OsXTH8 is differentially expressed in leaf sheath[1].
