Expression
Expressed in seedlings, roots, stems, leaf sheaths and blades and panicles. Zhang S et al.[1] use quantitative RT-PCR(qRT-PCR) to analyse RNA samples from different rice tissues at several developmental stages. The results showed that Oshox22 is ubiquitously expressed, with a lower level in stems and higher in panicles and seeds(Fig. 3a). They also monitored the Oshox22 expression under different abiotic stress conditions. As shown in Fig. 3b, Oshox22 was rapidly and strongly induced by NaCl, PEG and ABA, and weakly induced by low temperature.
Evolution
Oshox22 belongs to the homeodomain-leucine zipper (HD-Zip) family I of transcription factors. The HD-Zip genes, are an abundant group of transcription factors that are exclusively found in plants[1]The NJ tree (Fig. 5) shows that the HD-Zip genes of family I can be divided into nine clades as α, β1, β2, γ, δ, ε, ζ, φ1 and φ2[2]. Subfamilies IB, IC and ID all have an intron at the same position in the Zip region. Oshox22 belongs to subfamily IB.
Fig. 5 Family I is subdivided in clades α, β1, β2, γ, δ, ε, ζ, φ1 and φ2[2]. In the picture,after each gene, the intron subfamily is indicated with a box (family I), circle (family II) and triangle (family III), respectively, in different grey tones or patterns. Below: Subfamily division based on exon-intron organization. The exon-intron pattern is divided into seven subfamilies for family I (IA, IB, IC, ID, IE, IF and IG), and both family II (IIA, IIB, IIC and IID) and III (IIIA, IIIB, IIIC and IIID) have four subfamilies. Open and filled boxes represent coding and conserved domains, respectively. The HD, Zip and START domains are indicated in light grey, dark grey and black, respectively. The position of the introns is shown with black arrowheads. The white arrowhead and star (*) refers to an alternative transcript occurring with Oshox6 in subfamily IB
