Gene Details:

• Gene ID: Zm00001eb216870
• Gene Symbol: ZmLOX5 lox5
• Gene Name: lipoxygenase5
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Analysis of single and double lox5 and lox10 mutants showed that ZmLOX5 also contributed to insect defense by modulating ZmLOX10-mediated green leaf volatile signaling.
• Transposon-insertional disruption of ZmLOX5 resulted in the loss of resistance to insect herbivory.
• 9,10-KODA, an α-ketol produced by the tonoplast-localized 9-lipoxygenase ZmLOX5, plays a signaling role in maize defense against insect herbivory.
• Expression of ZmLOX5 is regulated by both wounding and simulated herbivory.
• Disruption of ZmLOX5 results in decreased wound-induced 9-oxylipins, 12-OPDA, JA, ABA, and benzoxazinoids.
• The transcripts of ZmLOX5 were increased in response to JA and salicylic acid treatments. ZmLOX5 was transiently induced both locally and systemically by wounding, which was accompanied by increased levels of 9-oxylipins, and fall armyworm herbivory, suggesting a putative role for this gene in defense against insects.
