Summary Enolases are key glycolytic enzymes that highly conserved in prokaryotic and eukaryotic organisms, among the most abundant cytosolic proteins. In this study we provide evidence activity of enolase ENO 2 is essential for growth development plants. We show Arabidopsis plants with compromised function, which were generated by mutating LOS 2/ locus, have severe cellular defects, including reduced cell size defective differentiation restricted lignification. At tissue organ level ‐deficient characterized shoots roots, altered vascular secondary stems, impaired floral organogenesis male gametophyte resulting embryo lethality as well delayed senescence. These phenotypes correlate lignin increased salicylic acid contents fatty soluble sugar composition. addition to an locus encodes transcription factor A t MBP ‐1, here reveal bifunctionality serves maintain homeostasis activity. summary, function required formation chorismate‐dependent metabolites, feedback‐inhibited ‐1 enable normal reproductive success
