Background Canopy architecture is critical in determining the fruit-zone microclimate and, ultimately, in determining an orchard’s success in terms of the quality and quantity of the fruit produced. However, few studies have addressed how the canopy environment leads to metabolomic and transcriptomic alterations in fruits. Designing strategies for improving the quality of pear nutritional components relies on uncovering the related regulatory mechanisms. Results We performed an in-depth investigation of the impact of canopy architecture from physiological, metabolomic and transcriptomic perspectives by comparing pear fruits grown in a traditional freestanding system (SP) or a flat-type trellis system (DP). Physiological studies revealed relatively greater fruit sizes, soluble solid contents and titratable acidities in pear fruits from DP systems with open canopies. Nontargeted metabolite profiling was used to characterize fruits at the initial ripening stage. Significant differences in fruit metabolites, including carbohydrates, nucleic acids, alkaloids, glycerophospholipids, sterol lipids, and prenol lipids, were observed between the two groups. Transcriptomic analysis indicated that a series of organic substance catabolic processes (e.g., the glycerol-3-phosphate catabolic process, pectin catabolic process and glucan catabolic process) were overrepresented in fruits of the DP system. Moreover, integrative analysis of the metabolome and transcriptome at the pathway level showed that DP pear fruits may respond to the canopy microenvironment by upregulating phenylpropanoid biosynthesis pathway genes such as PpPOD. Transient assays revealed that the contents of malic acid and citric acid were lower in the pear flesh of PpPOD RNAi plants, which was associated with regulating the expression of organic acid metabolism-related genes. Conclusions Our results provide fundamental evidence that at the physiological and molecular levels, open-canopy architecture contributes to improving pear fruit quality and is correlated with increased levels of carbohydrates and lipid-like molecules. This study may lead to the development of rational culture practices for enhancing the nutritional traits of pear fruits.

“…PPOs and POD oxidize phenolic substances to quinone derivatives, which are further oxidized to generate melanin pigmentation, which is present in organisms and is responsible for browning processes [35,36]. PPOs are a group of copper-containing enzymes that can catalyze the o-hydroxylation of monophenols to o-diphenols (tyrosinase activity) as well as the oxidation of o-diphenols to quinones (catecholase activity) in the presence of oxygen [37,38]. PAL converts phenylalanine into trans-cinnamic acid, which acts as a precursor for the further synthesis of phenolic compounds [34].…”

Browning and contamination are regarded as the main constraints in the plant tissue culture of Musa spp. that can hinder the success of plant propagation in vitro. Browning is caused by enzymatic reactions due to explant injury, while microbial contamination is caused by phyllospheric, rhizospheric, and endophytic microorganisms that reside on, in, and inside the plants. When not properly addressed, they can cause decreased regenerative ability, decreased callus growth, inhibited adventitious shoot growth, and even tissue death. To overcome the browning problem, various attempts have been made in vitro, e.g., immersing the explants in an anti-browning solution, incorporating anti-browning compounds into the medium, and manipulating cultural practices. Correspondingly, to control the problem of contamination, efforts have been made, for example, using various methods, such as thermotherapy, chemotherapy, and cryotherapy, and chemical agents, such as disinfectants, antiseptics, and nanoparticles. This review aims to investigate and provide a comprehensive understanding of the causes of browning and contamination as well as the many approaches used to control browning and contamination problems in Musa spp. tissue cultures.
