“…Root-promoting substances may contain purified active compounds, but also either defined or undefined mixtures of organic supplements, such as algae extracts, plant extracts and cell exudates, as well as microbial components (Serna et al 2012;Pacholczak et al 2012a, b;Stirk et al 2014). Studies confirmed that natural biopreparations may stimulate the development of plant organs, with a limited influence on the environment (Pacholczak et al 2012a, b;Okunlola and Ofuya 2013).…”

The study aimed at evaluating the response of common plum (Prunus domestica L.) microshoots during in vitro rooting in the presence of two phytoactive medium supplements, i.e. a dialyzate of pineapple pulp and a conditioned medium containing green algae Desmodesmus subspicatus exudates. Rooting efficiency was evaluated after 4 weeks of culture. During the root induction phase the content of phenolic compounds in shoot bases was determined and anatomical studies were conducted. Medium supplements were analyzed for the content of carbohydrates and phenolic acids. Both supplements were efficient in rooting induction of shoots of a difficult-to-root cultivar 'Węgierka Zwykła'. Medium supplementation allowed a significant reduction in the exogenous auxin content required for rooting. The highest rooting efficiencies on supplemented media were 28.9 and 27.8 %, in comparison with 33.3 % obtained in the control medium with doubled concentration of exogenous auxins. In the easy-to-root plum cultivar 'Węgierka Dąbrowicka' the rooting rate was slightly reduced in the presence of pineapple dialyzate, while in the presence of algal conditioned medium the rooting rate decreased substantially compared with the nonsupplemented medium. Approximately 30 % of 'Węgierka Dąbrowicka' shoots rooted on supplemented auxin-free media. The content of phenolic compounds accumulated in shoot bases during the root induction stage reflected the differences in rooting ability between both plum cultivars, indicating potential stressful conditions of the culture generated by the presence of phytoactive natural supplements. Anatomical study allowed to recognize the mode of dedifferentiation leading to adventitious rhizogenesis in the common plum. The results are discussed in relation to the composition of medium supplements and their potential root-promoting activity.

“…By contrast, in our hands this compound as well as its β ‐HO–C(3) isomer 57 exhibited no activity in the same assay ( Table ). The spirostanic analogues of natural steroids, in particular laxogenin, but also BB‐6 and BB‐16, additionally hydroxylated at C(2) or C(5) were reported to induce growth‐promoting effects in radish . In our hands, the two isomeric spirostanic analogs 59 and 60 fluorinated at C(5) were inactive in our French bean second internode elongation assay ( Table ).…”

A systematic investigation of structural modifications of brassinosteroids is presented. We describe in detail their synthetic preparation, which includes significant improvements of previously reported protocols as well as access to new analogs with functional modifications of the steroid skeleton and of the C(17)‐attached side chain. We report the biological potency of the prepared brassinosteroid analogs as plant hormones, which were carefully established in the French bean second internode elongation assay and discuss our observations in light of the recently reported structural data detailing the molecular interactions between brassinolide in the trimeric complex with the protein receptors kinases BRASSINOSTEROID INSENSITIVE 1 (BRI1) and SOMATIC EMBRYOGENESIS RECEPTOR KINASE 1 (SERK1). In a further part of this work we describe the preparation of H2O‐soluble pro‐forms of 24‐epicastasterone and we discuss their physical properties, hydrolytic stabilities and biological activity.

“…It has been reported that BRs analogues such as DI-31 promote photosynthetic capacity through the upregulation of Rubisco (the enzyme in charge of intercellular CO 2 assimilation) and chlorophyllase, and the transcription of encoded genes involved in photosynthesis under stress conditions (Anwar et al, 2018;Hussain et al, 2020;P erez-Borroto et al, 2021). On the other hand, foliar sprays of analogue BRs (DI-31) at low concentrations can induce stomatal opening under stress conditions, improving leaf gas exchange properties and plant water status (Serna et al, 2012c;Ch a vez -Arias et al, 2020). In this study, the lower foliar concentrations of DI-31 (1 or 2 mL⋅L-1) caused higher g s values related to the increase in E (Figure 3B and C).…”
