In the presented work, plant growth regulators (PGRs) were tested for their influence on biomass growth and accumulation of therapeutically-relevant indolizidine alkaloids in Securinega suffruticosa (Phyllanthaceae) callus cultures. The study included 9 auxins [2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid, indole-3-acetic acid (IAA), 4-chlorophenoxyacetic acid, indole-3-butyric acid, 4-amino-3,5,6-trichloropicolinic acid, b-naphthoxyacetic acid, 1-naphthaleneacetic acid, indole-3-propionic acid, one polar auxin transport inhibitor (2,3,5-triiodobenzoic acid) and 7 cytokinins [2-isopentenyladenine, 1-phenyl-3-(1,2,3-thiadiazol-5-yl)urea, N-(2-chloro-4-pyridinyl)-N 0 -phenylurea, diphenylurea, zeatin, kinetin (KIN), 6-benzylaminopurine]. The respective PGRs were applied at 0.5 and 5.0 mg l -1 , together with 5.0 or 0.5 mg l -1 KIN or 2,4-D (for auxins and cytokinins, respectively). The calli subjected to different phytohormone combinations (39 modifications in total) were evaluated for growth and alkaloid content, and the results tested for statistical differences. The highest concentrations of securinine (1.73 mg g -1 DW) and allosecurinine (3.11 mg g -1 DW) were recorded in the callus grown in the presence of 0.5 mg L -1 IAA and 5.0 mg L -1 KIN. To the best of the authors' knowledge, this is the first such comprehensive report concerning the influence of PGRs on alkaloid accumulation in plant in vitro cultures.

Plant tissue and organ culture has been extensively used from the beginning of the XX century for the study and comprehension of some primary biological mechanisms such as morphogenesis. However, with the increasing demand of the market for novel products derived from plants, in vitro culture became a reliable technique for the mass production of plant material. Moreover, the potential to use this technique for the production of some bioactive compounds, such as phenolic compounds, is immense since it allows the manipulation of the biosynthetic routes to increase the production and accumulation of specific compounds. This work intends to make a brief historical review of in vitro culture, highlighting its use for the production of bioactive compounds. Also, emphasizes the importance of phenolic compounds for the consumer as well reviews the metabolic pathways involved in its production in plant cells.Furthermore, it was carried out a comprehensive study on the work developed for the production of plant phenolic compounds in in vitro cultures, as well as on the type of elicitors used to increase of the same production; also a brief highlighting of the phenolic compounds which serve as elicitors. There are numerous reports directed to the production of phenolic extracts in in vitro plant cultures, however there is a lack in the production of individual phenolic compounds mainly due to the complexity of the biosynthetic routes and extraction procedures. Elicitation procedures are often used to increase the production of phenolics, archieving in most cases higher yields than in nonelicitated cultures. The increasing production of bioactive phenolic extracts/compounds allows for their further applicability, namely in the industry of functional foods or in pharmaceutical/medical fields.3

“…Among these factors, the plant growth stage was found overwhelming the effect of plant genotype on the total bacterial communities associated with potato (van Overbeek and van Elsas, 2008 ). In addition, it has been proved that the plant growth regulators could simulate lots of physiological processes in plants and improve the plant performance (Ren et al, 2011 ; Luczkiewicz et al, 2014 ). However, little information is available about the effects of growth regulators on the endophytes associated with plant leaves.…”

The aim of this study was to learn the interactions among the endophytic bacteria, the plant growth, the foliar spray of fulvic acid, and the accumulation of steviol glycosides in the leaves of Stevia rebaudiana. Metagenomic DNA was extracted from the Stevia leaves at different growth stages with or without the fulvic acid treatment; and the diversity of endophytic bacteria in Stevia leaves was estimated by pyrosequencing of 16S rRNA genes. As results, Proteobacteria, Actinobacteria, Bacteroidetes, and Firmicutes were found to be the dominant phyla despite the growth stages and fulvic acid application. Stevia growth stages strongly regulated composition of endophytic community. The genera Agrobacterium (12.3%) and Erwinia (7.2%) dominated in seedling stage were apparently declined in the vegetable and initial flowering stages, while Sphingomonas and Methylobacterium increased in mature leaves at harvest time, which showed that the mature leaves of Stevia preferred to accumulate some certain endophytic bacteria. Sphingomonas and Methylobacterium constituted an important part of the core endophytic community and were positively correlated with the stevioside content and UGT74G1 gene expression, respectively; while Erwinia, Agrobacterium, and Bacillus were negatively correlated with the stevioside accumulation. Fulvic acid treatment accelerated the variation of endophytes along the growth stages and increased the steviol glycosides content. This is the first study to reveal the community composition of endophytic bacteria in the Stevia leaves, to evidence the strong effects of growth stage and fulvic acid application on the endophytes of Stevia, and to demonstrate the correlation between the endophytic bacteria and the steviol glycosides accumulation.
