“…In Vicia faba , it has been shown that ABA-mediated stomata closure involves induction of an apoplastic CuAO activity as a source of H 2 O 2 , and that this activity is necessary to increase cytosolic Ca 2+ levels in response to ABA (An et al, 2008 ). Consistently with these observations, the apoplastic AtCuAOβ was shown to be expressed in guard cells (Ghuge et al, 2015b ). In addition, the peroxisomal AtCuAOζ which is expressed in guard cells is also involved in the ABA-mediated control of stomata opening (Qu et al, 2014 ).…”

“…Similarly, in Vicia faba, ABA induced an apoplastic CuAO (DAO) activity as a source of H 2 O 2 to increase cytosolic Ca 2+ level to mediate stomata closure (An et al, 2008). Consistent with these observations, the peroxisomal AtDAO was shown to be expressed in guard cells in response to the ABA-mediated control of stomata opening (Qu et al, 2014;Ghuge et al, 2015).…”

“…To further understand the interaction between JA and cytokinin, we analyzed the morphology of the root vasculature because cytokinin suppresses xylem formation whereas JA promotes xylem formation 39 . When we quantified the number of xylem cells in the roots of these plants by transverse sectioning and toluidine blue staining, we found that JA and cytokinin act antagonistically in xylem development (Fig.…”
