“…Sakhanokho and Kelley (2009) who revealed that the positive effect of SA on plant tissue culture propagation may be a reflection of an increase in the meristematic number, where SA acts as morphoregulator signal to support the assumption that SA is a growth regulator. Our obtained results about the significant role of SA on calli match with those of Galal (2012) who confirmed that the exogenous addition of SA in culture media affected positively calli, shoot, and root propagation of Ziziphus spina-christi.…”

Background: Rutin is one of the flavonoid compounds found in different plant species. Rutin has powerful antioxidant properties. The main target of this study is to elevate rutin content in gardenia (Gardenia jasmonides Ellis) calli cultures. Different concentrations of phenyl alanine (2, 3, 4, and 5 mg/l) were used as a precursor for enhancement of rutin accumulation. Moreover, and to elevate rutin content, salicylic acid (SA) was used at different concentrations (34.5, 69, 103.5, and 138 mg/l). Various biochemical analyses, i.e., determination of total phenols, total flavonoids, and antioxidant activity during three periods, after 2 weeks (the first harvest), after 4 weeks (the second harvest), and after 5 weeks (the third harvest) of culture, were performed. In addition, determination of phenols and flavonoids content by highperformance liquid chromatography (HPLC) were estimated of the three periods. Results: The results showed that the highest value of total phenols (9.53 ± 0.55 mg GAE/g DW of callus) was recorded with 5 mg/l phenylalanine (PA) at the third harvest. While the highest value of total flavonoids (0.358 ± 0.002 mg QE/g DW of callus) was achieved using 2 mg/l P.A. at the third harvest. By using HPLC, it was found that the maximum rutin content was recorded with 3 mg/l PA at the third harvest (429 μg/g DW).Conclusion: This study showed that rutin and cinnamic acids were the major compounds detected with all treatments and during the three harvest phases of gardenia calli cultures. As well as results declared that the decreasing of cinnamic acid was correlated with the increasing of rutin content, and the maximum rutin content was recorded with applying of 3 mg/l PA at the third harvest (429 μg/g DW).

“…A higher percentage of calli was induced by the addition of jasmonic acid to Vigna mungo tissue culture compared with the control (Mathews ). Salicylic acid is a phenolic compound found in plants that functions during plant growth, development, and photosynthesis (Raskin ) and, remarkably, positively affects plant callusing (Galal ). Together, these findings indicate that these DETs regulate the process of embryonic callus formation by responding to different hormone signals during cell enlargement, cell division, the suppression of cell differentiation, dedifferentiated cell maintenance and growth.…”

In this study, a maize inbred line with a strong capacity to induce embryonic callus, 18-599R, was used to analyze the transcription factors expressed during embryonic callus formation. A total of 1180 transcription factors were found to be expressed during three key stages of callus induction. Of these, compared with control, 361, 346 and 328 transcription factors were significantly downregulated during stages I, II and III, respectively. In contrast, 355, 372 and 401 transcription factors (TFs) were upregulated during the respective stages. We constructed a transcription factor-mediated regulatory network and found that plant hormone signal transduction was the pathway most significantly enriched among TFs. This pathway includes 48 TFs regulating cell enlargement, cell differentiation, cell division and cell dedifferentiation via the response to plant hormones. Through real-time polymerase chain reaction (PCR) and degradome sequencing, we identified 23 transcription factors that are regulated by miRNA. Through further analysis, ZmMYB138, a member of the MYB transcription factor family localized in the nucleus, was verified to promote embryonic callus formation in the maize embryo through GA signal transduction.

“…As a phenolic compound, Salicylic acid (SA) is found in plants, it has a role in a variety of physiological and biochemical processes. Exogenously applied SA is beneficial to plant growth and development [23,24]. Pyruvic acid is a junction molecule that gives energy to cells via the citric acid cycle (known as the Krebs cycle) when oxygen is present (aerobic respiration) and ferments to generate lactate (lactic acid) when oxygen is not available (anaerobic respiration) [25,26].…”

Chitosan nanoparticles (ChNPs) as a biodegradable and biocompatible substance were employed as a bio-elicitor to stimulate the biosynthesis of bioactive metabolites in avocado callus. Effect of in-situ encapsulation of different active compounds (Salicylic acid, Phenylalanine, Methionine and Ca-Pyruvate) onto ChNPs during preparation was performed using ionic gelation method. The prepared encapsulated nanoparticles were characterized using transmission electron microscope (TEM) and dynamic light scattering (DLS) techniques. The formulated ChNPs had a beneficial effect on the majority of the indicators tested on Murashige and Skoog (MS) medium. The results indicated that maximum mean value of callus fresh weight before the addition of nano-Chitosan was 215 mg/jar, and ChNPs encapsulated methionine 40 mg/L had the greatest mean record of callus fresh weight and glutathione content with low malondialdehyde (MDA) concentration of 0.993 nmol/g. However, ChNPs encapsulated salicylic acid at 100mg/L has the best antioxidant capacity due to a 40.88% rise in the content of the essential oil 3,4-Dihydro-2H-1,5-(3"-T-butyl) benzodioxepine and the largest accumulation of polyphenolic components. The current approach involved analysing molecular amplified fragment-length polymorphism (AFLP) using genomic DNA with two restriction enzymes (EcoRI and MseI) EcoR I-ACA and MseI-CTC primer pairs. The present work provides an efficient method for enhancing the bio-active compounds bioaccumulation in avocado callus using encapsulated ChNPs.
