| + | * ''xa5'' is a recessive, race-specific ''R'' gene that provides immunity to races of ''Xanthomonas oryzae'' pv. ''oryzae'' expressing ''avrxa5'', the cognate avirulence gene to ''xa5''. ''X. oryzae'' pv. ''oryzae'' causes rice bacterial blight, a severe disease in South and Southeast Asia. ''Avrxa5'' is likely to be a member of the ''AvrBs3'' family of proteins (Bai et al., 2000; Hopkins et al., 1992), which are usually characterized by nuclear localization signals and transcriptional activation domains (Bonas and Lahaye, 2002). | ||

| + | * ''xa5'' is a naturally occurring mutation that is most commonly found in the Aus-Boro group of rice (''Oryzae sativa L.'') varieties from the Bangladeshi region of Asia (Garris et al., 2003).There are over 20 resistance genes to ''X. oryzae'' pv. ''oryzae'', three of which have been cloned (''Xa21,Xa1,'' and ''Xa26'') and fall into one of the five typical ''R'' gene classes (Song et al., 1995; Sun et al., 2004; Yoshimura et al., 1998). ''Xa21'' and ''Xa26'' both encode NBS-LRR proteins containing a kinase domain, while ''Xa1'' encodes a member of the NBS-LRR class. | ||

| + | * ''xa5'' does not resemble either of the two cloned recessive resistance genes in plants, ''mlo'' or ''RRS1-R''. In contrast to ''xa5'', resistance governed by barley mlois not race-specific (Buschges et al., 1997). Mutations in ''Mlo'' result in immunity to nearly all isolates of the fungal pathogen ''Erysiphe graminis'' f. sp. hordei. The ''RRS1-R'' gene from ''Arabidopsis'' provides resistance to several strains of ''Ralstonia solanacearum'' and encodes an NBSLRR protein with a WRKY motif characteristic of some plant transcription factors (Deslandes et al., 2002). The ''RRS1-R'' gene product physically interacts with its cognate protein PopP2 (Deslandes et al., 2003). Unlike ''xa5'', ''RRS1-R'' shares many characteristics with dominant ''R'' genes (Deslandes et al., 2003). For example, while genetically defined as recessive, ''RRS1-R'' behaves as a dominant gene in transgenic plants and is a member of the NBS-LRR ''R'' gene class. | ||

Annotated Information
Gene Symbol
- Os05g0107700 <=> xa-5, xa5,OsXA5
Function
- The gene xa5 provides racespecific resistance to X. oryzae pv. oryzae, and encodes the small subunit of transcription factor IIA(TFIIAγ).
- This recessive gene provides race-specific resistance to X. oryzae pv. oryzae, and is structurally unlike the more than 40 plant R genes previously cloned.
- xa5 is inherited in a completely recessive manner and the susceptible allele Xa5 is fully dominant.
- xa5-mediated recessive resistance is the result of restricted bacterial movement, but not restricted multiplication.
Evolution
- xa5 is a recessive, race-specific R gene that provides immunity to races of Xanthomonas oryzae pv. oryzae expressing avrxa5, the cognate avirulence gene to xa5. X. oryzae pv. oryzae causes rice bacterial blight, a severe disease in South and Southeast Asia. Avrxa5 is likely to be a member of the AvrBs3 family of proteins (Bai et al., 2000; Hopkins et al., 1992), which are usually characterized by nuclear localization signals and transcriptional activation domains (Bonas and Lahaye, 2002).
- xa5 is a naturally occurring mutation that is most commonly found in the Aus-Boro group of rice (Oryzae sativa L.) varieties from the Bangladeshi region of Asia (Garris et al., 2003).There are over 20 resistance genes to X. oryzae pv. oryzae, three of which have been cloned (Xa21,Xa1, and Xa26) and fall into one of the five typical R gene classes (Song et al., 1995; Sun et al., 2004; Yoshimura et al., 1998). Xa21 and Xa26 both encode NBS-LRR proteins containing a kinase domain, while Xa1 encodes a member of the NBS-LRR class.
- xa5 does not resemble either of the two cloned recessive resistance genes in plants, mlo or RRS1-R. In contrast to xa5, resistance governed by barley mlois not race-specific (Buschges et al., 1997). Mutations in Mlo result in immunity to nearly all isolates of the fungal pathogen Erysiphe graminis f. sp. hordei. The RRS1-R gene from Arabidopsis provides resistance to several strains of Ralstonia solanacearum and encodes an NBSLRR protein with a WRKY motif characteristic of some plant transcription factors (Deslandes et al., 2002). The RRS1-R gene product physically interacts with its cognate protein PopP2 (Deslandes et al., 2003). Unlike xa5, RRS1-R shares many characteristics with dominant R genes (Deslandes et al., 2003). For example, while genetically defined as recessive, RRS1-R behaves as a dominant gene in transgenic plants and is a member of the NBS-LRR R gene class.
