-====== Walnut (//Juglans regia //L.) ======
-===== Pathogen: //Xanthomonas arboricola// pv. //juglandis// =====
-No resistance genes identified in walnut to date (Frutos //et al//., 2010; Lamichane, 2014; Jiang //et al//., 2019). Existence of some important accessions of Walnut //Juglans regia// with some levels of resistance to //X. arboricola //pv. //juglandis// (Lamichhane, 2014). A polyphenol oxidase enzyme was however shown to be associated with tolerance to //Brenneria rubifaciens//, //Brenneria nigrifluens//, and //X. arboricola// pv. juglandis (//Xaj//) (Frutos //et al.//, 2010; see entry below).
-==== Resistance gene: //jrPP01// (tolerance gene) ====
-=== Synonyms ===
-//NA//
-=== Source ===
-//Juglans regia// (Frutos //et al.//, 2010).
-=== Status (identified, mapped, cloned, sequenced) ===
-Sequenced (GenBank [[https://www.ncbi.nlm.nih.gov/protein/ACN86310.1|ACN86310.1]]; Martínez‐García //et al//., 2016).
-=== Molecular markers ===
-Gene-specific PCR primers (JrPPO1-F-cd and JrPPO1-R-cd) (Martínez‐García //et al//., 2016).
-=== Brief description ===
-Encodes a polyphenol oxidase enzyme (jrPPO) expressed in the leaves, hulls and flowers of the host (Escobar //et al//., 2008).

-====== Hazelnut (//Corylus avellana// L.) ======
-===== Pathogen: //Xanthomonas arboricola// pv. //corylina// =====
-No resistance genes identified in hazelnut to date (Frutos, 2010; Lamichane & Varvaro, 2014). Problems on selection of varieties resistant to //X. arboricola// pv. //corylina// attacks (Avanzato //et al//., 2009). Existence of hazelnut cultivars with a low susceptibility level to //X. arboricola// pv. //corylina// (Prunier //et al//., 1976); some cultivars seem to be more tolerant than others, but no real resistance has been found (Frutos, 2010).
