Gene Details:

• Gene ID:
• Gene Symbol: CaHsp26.5
• Gene Name: HEAT SHOCK PROTEIN 26.5
• Genome:
• Species: Capsicum annum

Functional Descriptions:

• The expression of Capsicum annuum HEAT SHOCK PROTEIN 26.5 (CaHsp26.5) was triggered by the inoculation of Tobacco mosaic virus pathotype P0 (TMV-P0) but its function in the defense response of plants is unknown.
• An elevated CaHsp26.5 level was accompanied by increased plant resistance against plant viruses such as Cucumber mosaic virus strain Korea.
• CaHsp26.5 binding to a short poly-cytosine motif in the 3’-untranslated region of the genome of some viruses triggers the expression of several defense-related genes such as PATHOGENESIS-RELATED GENE 1 with the help of a transcription factor, NAC DOMAIN-CONTAINING PROTEIN 81 (ATAF2).
• Our work shows CaHsp26.5 as a positive player in the plant defense response against several plant RNA viruses. However, some tobamoviruses can hijack CaHsp26.5’s chaperone activity for their own benefit.
