“…hadecloth is used in the production of a variety of vegetable, fruit, and ornamental crops, especially in tropical and subtropical regions (Armitage, 1991;D ıaz-P erez, 2013;Halevy et al, 2002;Ili c et al, 2012;Marini and Sowers, 1990;Wolff and Coltman, 1990). Shadecloth provides a microclimate with reduced PAR, air temperature, root zone temperature, and changes in relative humidity (Kittas et al, 2012;Stamps, 2009).…”

Colored shadecloths are used in the production of vegetable, fruit, and ornamental crops to manipulate the light spectrum and to induce specific plant physiological responses. The influence of three colored shadecloths (red, blue, and black) with 50% shade and a no-shade control on the production of two lettuce (Lactuca sativa) cultivars [Two Star (green-leaf) and New Red Fire (red-leaf)] and snapdragon (Antirrhinum majus) was investigated. Use of shadecloth increased plant growth indices of lettuce and total length of snapdragon flower stems (at the first harvest) compared with no-shade control. Red shadecloth resulted in longer flower stems of snapdragon (at the second harvest) than black and blue shadecloths and no-shade control. However, shadecloth delayed blooming of snapdragon for 1 week compared with no-shade control. Stomatal conductance (gs) and leaf transpiration rate of both lettuce cultivars and photosynthetic rate and transpiration rate of snapdragon were decreased in response to shadecloth treatments. All shadecloths decreased health beneficial flavonoids (luteolin/quercetin glucuronide and quercetin malonyl concentrations for both lettuce cultivars and cyanidin glucoside in red-leaf lettuce). The two lettuce cultivars varied in their phenolic compounds, with the green-leaf ‘Two Star’ having higher quercetin glucoside and caftaric acid than red-leaf ‘New Red Fire’, whereas ‘New Red Fire’ had higher concentrations of chlorogenic acid, luteolin/quercetin glucuronide, and quercetin malonyl. Shadecloths reduced substrate temperature and photosynthetically active radiation (PAR) to about half of full sunlight compared with no-shade control, which may have contributed to reduced gs and leaf transpiration (for lettuce and snapdragon), decreased phenolic compounds in lettuce, and delayed flowering of snapdragon.

“…In P . grandiflorus , flowering is accelerated at elevated temperatures, whereas the treatment of GA 3 does not affect flowering [ 18 , 43 ], indicating the importance of ambient temperature to P . grandiflorus flowering.…”

“…It was shown that the flowering timing of P . grandiflorus was not affected by photoperiod and gibberellin together but was significantly accelerated by high temperature [ 18 ]. Similarly, the day-natural tomato flowering is regulated by the FT-homologue SFT/SP3D gene, which is regulated independently of CO and day length [ 11 , 19 ].…”

Platycodon grandiflorus roots have been used as a foodstuff and traditional medicine for thousands of years in East Asia. In order to increase the root development of P. grandiflorus, cultivators removed the inflorescences, suggesting the possible negative effect of flowering on root development. This indicates that the genetic improvement of P. grandiflorus by late flowering is a potential approach to increase productivity. However, nothing is known about key genes integrating multiple flowering pathways in P. grandiflorus. In order to fill this gap, we identified potential homologs of the FLOWERING LOCUS T (FT) gene in P. grandiflorus. The alignment with other FT members and phylogenetic analysis revealed that the P. grandiflorus FT (PlgFT) protein contains highly conserved functional domains and belongs to the FT-like clade. The expression analysis revealed spatial variations in the transcription of PlgFT in different organs. In addition, the expression level of PlgFT was increased by high temperature but not by photoperiodic light input signals, presumably due to lacking the CONSTANS binding motif in its promoter region. Furthermore, PlgFT induced early flowering upon its overexpression in P. grandiflorus, suggesting the functional role of PlgFT in flowering. Taken together, we functionally characterized PlgFT as a master regulator of P. grandiflorus flowering under inductive high temperature, which will serve as an important target gene for improving the root productivity.

“…Its root, called doraji in Korea, jiegeng in China, and kikyo in Japan, has been widely used as a traditional medicine in these countries [ 2 ]. In addition, P. grandiflorus , which is also used as a vegetable and an ornamental plant, shows strong ecological adaptability facilitated by resistance to drought, cold, and disease [ 3 , 4 ]. Codonopsis lanceolata (bonnet bellflower) exhibits various health benefits including antioxidant, antimicrobial, anti-inflammatory, and immune-modulating properties.…”

Platycodon grandiflorus (balloon flower) and Codonopsis lanceolata (bonnet bellflower) are important herbs used in Asian traditional medicine, and both belong to the botanical family Campanulaceae. In this study, we designed and implemented a de novo DNA sequencing and assembly strategy to map the complete mitochondrial genomes of the first two members of the Campanulaceae using low-coverage Illumina DNA sequencing data. We produced a total of 28.9 Gb of paired-end sequencing data from the genomic DNA of P. grandiflorus (20.9 Gb) and C. lanceolata (8.0 Gb). The assembled mitochondrial genome of P. grandiflorus was found to consist of two circular chromosomes; the master circle contains 56 genes, and the minor circle contains 42 genes. The C. lanceolata mitochondrial genome consists of a single circle harboring 54 genes. Using a comparative genome structure and a pattern of repeated sequences, we show that the P. grandiflorus minor circle resulted from a recombination event involving the direct repeats of the master circle. Our dataset will be useful for comparative genomics and for evolutionary studies, and will facilitate further biological and phylogenetic characterization of species in the Campanulaceae.
