Segments can be cut from the peducular-1 internode of oat (Avena sativa L.) shoots so as to contain the graviresponsive, auxin-sensitive leaf sheath pulvinus, and the gibberellin-sensitive internodal tissue. These two growth-capable tissues were used to study the effects and interactions of jasmonic acid (JA) and abscisic acid (ABA) in regulating cell elongation. When supplied alone at physiologic concentrations (10−5, 10−4 m), JA promoted growth and cell wall synthesis in the internodal tissue… CONTINUE READING
