<p>This study investigated the effects of different sugars (sucrose, fructose, glucose) and sugar alcohols (mannitol, sorbitol) applied alone and in solution with methyl jasmonate (JA-Me) on the anthocyanin content in the roots of <em>Kalanchoe blossfeldiana</em>. None of the sugars used individually in the experiment affected anthocyanin accumulation in the roots of intact plants. The anthocyanin level was similar to that in the control. Sucrose at concentrations of 0.5% and 3.0%, and glucose at a concentration of 3.0% inhibited anthocyanin accumulation induced by JA-Me. Only fructose at a concentration of 3.0% stimulated anthocyanin accumulation induced by JA-Me. The sugar alcohols, mannitol at a concentration of 3.0% and sorbitol at 0.5% and 3.0%, inhibited anthocyanin accumulation in the roots of intact <em>K. blossfeldiana</em> plants induced by JA-Me. In excised roots, both sugars and JA-Me used individually did not affect the formation of anthocyanins. Also, the sugar alcohols (mannitol and sorbitol) applied simultaneously with JA-Me had no effect on the accumulation of anthocyanins. However, roots treated with sugars (sucrose, fructose, glucose) in solution with JA-Me promoted the induction of anthocyanins in the apical parts of the roots. </p><p>The results suggest that anthocyanin elicitation in the roots of <em>K. blossfeldiana</em> by methyl jasmonate may be dependent on the interaction of JA-Me with sugars transported from the stems (leaves) to the roots.</p>

AbstractThe influence of methyl jasmonate on anthocyanin accumulation in roots ofKalanchoe blossfedianaplants was studied. Methyl jasmonate (JA-Me), at a concentration of 5.0 to 40.0 mg.l−1, substantially increased anthocyanin accumulation in roots of intact plants, when it was applied as a solution under natural light conditions. The production of anthocyanin depended on the concentration of methyl jasmonate and the age of the plant. The stimulatory effect was higher in older plants ofK. blossfeldianathan in younger ones. When leaves were removed methyl jasmonate slightly stimulated anthocyanin accumulation compared with intact plants. The obtained results indicate that leaves are necessary for the anthocyanin accumulation in the roots. In isolated roots methyl jasmonate did not affect the accumulation of anthocyanins in light conditions. Seven anthocyanins were documented in the roots of control plants and 8 anthocyanins in the roots of JA-Me treated ones. JA-Me increased the level of anthocyanins in roots of oldK. blossfeldianaplants 6.8, 6.0 and 3.6-folds, after 4, 8 and 14-days of treatment, respectively.

AbstractIn this study, we investigated the effect of plant growth regulators (PGRs) - auxins, gibberellin, cytokinin, abscisic acid, brassinosteroid, ethylene and their interaction with methyl jasmonate (JA-Me) applied to roots of the whole plants Kalanchoe blossfeldiana on the accumulation of anthocyanins in roots. The highest stimulation of anthocyanins synthesis was stated with application of JA-Me alone. In response to treatments with the other tested PGRs, the content of anthocyanins in roots of a whole plant was different depending on the concentration of the PGR when being applied alone or together with JA-Me. Auxin, indole-3-acetic acid (IAA) at a concentration of 50 mg·L-1, indole-3-butyric acid (IBA) at 5 mg·L-1 and abscisic acid (ABA) at 10 mg·L-1 induced anthocyanin accumulation with approximately 60-115% compared to the control while 24-epibrassinolid (epiBL), gibberellic acid (GA3) and 6-benzylaminopurine (BAP) had no effect on the anthocyanin accumulation. The simultaneous administration of the PGRs with JA-Me usually resulted in the accumulation of anthocyanins in roots in a manner similar to that caused by JA-Me. PGRs applied to isolated roots did not stimulate anthocyanin accumulation, except for the combination of JA-Me with 50 mg·L-1 IAA. The results indicate that in K. blossfeldiana, the aboveground parts of the plant play an important role in the biosynthesis of anthocyanins in roots.

It was found previously that methyl jasmonate (JA-Me) induced leaf abscission in <i>Kalanchoe blossfeldiana</i>. In present studies it was showed that JA-Me did not affect or only slightly affected the content of free and bound fatty acids in petioles and blades. ß-Sitosterol, campesterol and ß-amyrin were identified in petioles and blades of <i>K. blossfeldiana</i>; JA-Me decreased the content of campesterol in petioles and increased the content of ß-sitosterol in blades. In blades of plants treated with JA-Me disappearance of olean-12-one was indicated but appearance of 2H-cyclopropa[a]-naphthalen-2-one,l, la, 4, 5, 6, 7, 7a, 7b-octahydro-l, 1, 7, 7a-tetramethyl (aristolone) was documented. The significance of these findings in leaf abscission induced by methyl jasmonate in <i>K. blossfeldiana</i> is discussed.

It was found previously that methyl jasmonate (JA-Me) induced leaf abscission in <em>Kalanchoe blossfeldiana</em>. In present studies it was shown that JA-Me markedly increased the total activities of cellulase, polygalacturonase, pectinase and xylanase in petioles, but did not affect activities of these enzymes in the blades and apical part of shoots of <em>K. blossfeldiana</em>. These results suggest that methyl jasmonate promotes the degradation of cell wall polysaccharides in the abscission zone and in this way induces leaf abscission in <em>Kalanchoe blossfeldiana</em>.

Kalanchoe blossfeldiana Poelln. is a common ornamental houseplant. Although powdery mildew is a major disease of this species, there are no published reports of it in the Pacific Northwest. In August, 2002, powdery mildew was observed on six indoor K. blossfeldiana plants in an office and adjacent laboratory at the Puyallup Research and Extension Center. Accepted for publication 25 March 2003. Published 17 April 2003.

Anthocyanins are vital components of plant secondary metabolites, and are also the most important coloring substances in wine. Teinturier cultivars are rich in anthocyanins. However, the differences in anthocyanin accumulation and profiles between teinturier and non-teinturier cultivars have not been reported. In this study, Yan 73 and Dunkelfelder were selected as the experimental materials, and three non-teinturier cultivars were used for comparison. LC-MS and qRT-PCR were used to determine the individual anthocyanin contents and the relative gene expression. The results show that the total anthocyanin content of the teinturier cultivars was considerably higher than that in non-teinturier cultivars, and the levels of individual anthocyanins increased gradually during ripening. Lower ratios of modified anthocyanins were found in the teinturier cultivars, which was not only due to the high expression level of VvUFGT and VvGST4, but also due to the relatively low expression of VvOMT in these cultivars. Cluster analysis of gene expression and anthocyanin accumulation showed that VvUFGT is related to anthocyanin accumulation, and that AM1 is related to the synthesis and transport of methylated anthocyanins. Our results will be useful for further clarifying the pathways of anthocyanin synthesis, modification, and transport in teinturier cultivars.
