Parallel analysis of global garlic gene expression and alliin content following leaf wounding

Abstract Background Allium sativum (garlic) is an economically important food source and medicinal plant rich in sulfides other protective substances such as alliin, the precursor of allicin biosynthesis. Cysteine, serine sulfur alliin However, little known about content under abiotic stress or mechanism by which it synthesized. Results The findings revealed that was lowest garlic roots, highest buds. Furthermore, levels decreased mature leaves following wounding. Transcriptome data generated over time after wounding further significant up-regulation genes integral to biosynthetic pathways cysteine leaves. Conclusions suggest differential expression cysteine, sulfide-related underlies accumulation its precursors garlic, providing a basis for analyses
