“…JA-Me at a concentration of 0.5 % in lanolin paste induced the formation of the secondary abscission zone and senescence in several types of stem explants (only internode segment, internode segment with nodes and without leaves, internode segment with nodes and debladed petioles) of Bryophyllum calycinum when it was applied in various places of the stem or the debladed petiole as lanolin paste (Saniewski et al 2000). In the presence of small leaves in stem explants JA-Me also induced the formation of the secondary abscission zone and senescence but the presence of larger leaves completely inhibited JA-Me-induced processes.…”

Growth and development of plants are regulated by interactions among different plant growth substances. During stress conditions, both abiotic and biotic, interaction of the some hormones activates defense responses. The present review describes the interaction between j asmonates and auxin in regulation of some physiological processes in plant growth and development. Some jasmonate-induced processes reduced by auxins and some auxin stimulated physiological processes inhibited by jasmonates are the focus of this review. Therefore, the following physiological processes are described: stem cell growth, abscission, secondary abscission zone formation, tendril coiling, opening of the pulvinules in Mimosa pudica, wounding and induced gene expression, nicotine biosynthesis and auxin biosynthesis in Brassicaceae.

“…Crassulaceae including Bryophyllum calycinum, Kalanchoe blossfeldiana and Crassula lycopodioides is one of the important plant families for horticulture. Methyl jasmonate (JA-Me) has been demonstrated to induce the secondary abscission zone formation and senescence in several types of stem explants of Bryophyllum calycinum, such as the internode segment only, and the internode segment with nodes and without leaves, when it was applied on the stem as a lanolin paste [32]. It should be mentioned that in the presence of small leaves in stem segments, JA-Me induced the secondary abscission zone formation and senescence, but the presence of larger leaves completely inhibited such effects of JA-Me.…”

“…It should be mentioned that in the presence of small leaves in stem segments, JA-Me induced the secondary abscission zone formation and senescence, but the presence of larger leaves completely inhibited such effects of JA-Me. Auxin, indole-3-acetic acid (IAA), applied to a detached leaf totally prevented the formation of the secondary abscission zone in the stem tissues induced by JA-Me [32], suggesting that the interaction of JA-Me with IAA transported from leaves plays an important role in the secondary abscission zone formation. Only IAA application is also found to substantially induce the formation of the secondary abscission zone in internode explants, petiole segments, the petiole after excision of leaf blade in intact plants, and decapitated stems in intact plants of B. calycinum [33].…”

The interaction of methyl jasmonate (JA-Me) and indole-3-acetic acid (IAA) to induce the formation of the secondary abscission zone in the middle of internode segments of Bryophyllum calycinum was investigated in relation to auxin status and histology. When IAA at 0.1% (w/w, in lanolin) was applied to the segments, the formation of the secondary abscission zone at a few mm above the treatment in the apical direction was observed. On the contrary, IAA at 0.5% (w/w, in lanolin) did not induce the formation of the secondary abscission zone. JA-Me at 0.5% (w/w, in lanolin) applied to the middle of internode segments kept in the normal (natural) or inverted positions also induced the formation of the secondary abscission zone below and above parts of the treatment. IAA at 0.5% applied to the cut surface of the upper part of the segments completely prevented the formation of the secondary abscission zone induced by JA-Me. Simultaneous application of IAA 0.5% with JA-Me 0.5% in the middle part of the internode segments induced the formation of the secondary abscission zone at 10 mm to 12 mm above the treatment. Histological analyses indicated that the formation of the secondary abscission zone was characterized by the presence of newly synthesized cell plates that resulted from periclinal cell division within one layer of mother cells in stems. The effects of IAA (0.1%) and JA-Me (0.5%) on the formation of the secondary abscission zone were histologically similar. Comprehensive analyses of plant hormones revealed that the balance of the endogenous levels of IAA in both sides adjacent to the abscission zone was significantly disturbed when the secondary abscission formation was induced by the application of IAA. These results strongly suggest that an auxin gradient is important in the formation of the secondary abscission zone in the internode segments of B. calycinum, and IAA gradient results from polar IAA transport from the application site. IAA is important in the regulation of formation of the secondary abscission zone induced by JA-Me. Further possible mechanisms of the formation of the secondary abscission zone in the internode segments of B. calycinum are also discussed in the interaction of JA-Me and IAA.

“…Methyl jasmonate was found to increase citrus and tomato abscission (http://www.plantphysiol.org/cgi/content/ abstract/44/8/1144; Beno-Moualem, 2004) and to determine the induction of a secondary AZ in Bryophyllum stem (Saniewski et al, 2000). Polyamines were indicated to retard abscission (Malik and Singh 2003), to increase fruit set in litchi (Stern and Gazit, 2000) and in grapevine (Aziz et al, 2001).…”
