Annotated Information
Function
- In rice, ETR2 reduces ethylene sensitivity, delays the transition fromthe vegetative stage to the floral stage, and affects starch accumulation.
Expression
Please input expression information here.
Evolution
- The rice ETR2 kinase domain was compared with those from other ethylene receptors or homologs (Figure 1). Alignment of the amino acid sequences of the ethylene receptor kinase domains of various ethylene recpetors. The positions of the H, N, G1, F, and G2 box are indicated on top of the sequence based on the corresponding boxes from Arabidopsis ETR1. The amino acids shaded in black are identical to each other. Five mutated amino acids (G to A, E to Q, R to Q, F to A, and G to A) upstream of and within the N box are also indicated, and the mutated protein N was used for kinase analysis in Figure 2. At ETR1, At ETR2, and At EIN4 are from Arabidopsis. NTHK1 and NTHK2 are from tobacco. Zm ETR2 is from maize. The Os ETR2/Os PK1, Os ETR3/Os PK2, and Os ETR4/Os PK3 receptors are from rice.
