The mode of action of 1-naphthylphthalamic acid (NPA) to induce conspicuous local stem swelling in the area of its application to the growing internode in intact Bryophyllum calycinum was studied based on the aspects of histological observation and comprehensive analyses of plant hormones. Histological analyses revealed that NPA induced an increase in cell size and numerous cell divisions in the cortex and pith, respectively, compared to untreated stem. In the area of NPA application, vascular tissues had significantly wider cambial zones consisting of 5–6 cell layers, whereas phloem and xylem seemed not to be affected. This indicates that stem swelling in the area of NPA application is caused by stimulation of cell division and cell enlargement mainly in the cambial zone, cortex, and pith. Comprehensive analyses of plant hormones revealed that NPA substantially increased endogenous levels of indole-3-acetic acid (IAA) in the swelling area. NPA also increased endogenous levels of cytokinins, jasmonic acid, and its precursor, 12-oxo-phytodienoic acid, but did not increase abscisic acid and gibberellin levels. It was shown, using radiolabeled 14C-IAA, that NPA applied to the middle of internode segments had little effect on polar auxin transport, while 2,3,5-triiodobenzoic acid substantially inhibited it. These results strongly suggest that NPA induces changes in endogenous levels of plant hormones, such as IAA, cytokinins, and jasmonic acid, and their hormonal crosstalk results in a conspicuous local stem swelling. The possible different mode of action of NPA from other polar auxin transport inhibitors in succulent plants is extensively discussed.

“…Phytohormones play a crucial role in the development process as well as in the integration of environmental signals to various physiological processes in plants. Among them, jasmonates (methyl jasmonate (JA-Me), jasmonic acid (JA), and their related compounds (JAs)), of which JA and JA-Me were first isolated from wormwood ( Artemisia absinthium ) and Cleyera ochnacea as senescence-promoting substances [ 20 , 21 ], are essential for the regulation of senescence in plants [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. The role of JA-Me in stress in plants is well known [ 29 ].…”

“…The role of JA-Me in stress in plants is well known [ 29 ]. JAs have also been demonstrated to be involved in triggering various biochemical and physiological processes in plants [ 22 , 23 , 24 , 30 , 31 , 32 , 33 ]. For example, they play key roles in the metabolism pathway of various secondary metabolites [ 34 , 35 ], lignins [ 36 , 37 ], and phenolic acids [ 38 , 39 ].…”

“…Since ginkgolides and bilobalide are difficult to synthesize chemically due to their complex chemical structures and their contents in G. biloba leaves are low, developing methods and/or treatments to increase their biosynthesis and accumulation possesses an important medical value. In our previous study, it was shown that JA-Me applied in lanolin paste to the abaxial side of the leaves of G. biloba clearly induces leaf senescence indicated as chlorophyll degradation but applied to the adaxial side does not [ 22 ]. However, the effect of such application of JA-Me on important secondary metabolites in relation to leaf senescence in Ginkgo biloba leaves has not been demonstrated.…”

The present study compared the effects of natural senescence and methyl jasmonate (JA-Me) treatment on the levels of terpene trilactones (TTLs; ginkgolides and bilobalide), phenolic acids, and flavonoids in the primary organs of Ginkgo biloba leaves, leaf blades, and petioles. Levels of the major TTLs, ginkgolides B and C, were significantly higher in the leaf blades of naturally senesced yellow leaves harvested on 20 October compared with green leaves harvested on 9 September. In petioles, a similar effect was found, although the levels of these compounds were almost half as high. These facts indicate the importance of the senescence process on TTL accumulation. Some flavonoids and phenolic acids also showed changes in content related to maturation or senescence. Generally, the application of JA-Me slightly but substantially increased the levels of TTLs in leaf blades irrespective of the difference in its application side on the leaves. Of the flavonoids analyzed, levels of quercetin, rutin, quercetin-4-glucoside, apigenin, and luteolin were dependent on the JA-Me application site, whereas levels of (+) catechin and (−) epicatechin were not. Application of JA-Me increased ferulic acid and p-coumaric acid esters in the petiole but decreased the levels of these compounds in the leaf blade. The content of p-coumaric acid glycosides and caffeic acid esters was only slightly modified by JA-Me. In general, JA-Me application affected leaf senescence by modifying the accumulation of ginkogolides, flavonoids, and phenolic acids. These effects were also found to be different in leaf blades and petioles. Based on JA-Me- and aging-related metabolic changes in endogenous levels of the secondary metabolites in G. biloba leaves, we discussed the results of study in the context of basic research and possible practical application.

Effect of 2,4-D pre-treatment on quality during ripening of on-tree longan fruit

et al. 2021

The aim of this study was to investigate the effect of 20 mg/L 2,4-D on the quality during ripening of on-tree longan fruits. We investigated external and internal properties of the on-tree longan fruits. The results showed that 2,4-D treatment promotes the growth based on the fruit size and weight. The respiration rate, contents of TSS, total soluble sugar, sucrose, glucose, fructose, and hexose revealed an increasing tendency with advancing the maturity and reached the high status during 110-126DPA. By contrast, the relative electric conductivity and TA content displayed a declining trend during the ripening stage, increase with the senescence. All these pieces of information indicated that 2,4-D treatment could effectively promote the sensory quality of on-tree longan fruit, prolong the harvest time to 118DPA, while CK should harvest before 110DPA.
