“…Rich germplasm resources for Lilium spp. are available in China, some of which (e.g., Lilium regale Wilson) are resistant to B. elliptica infection (Du et al 2014;Gao et al 2017). However, the molecular basis of lily resistance to this fungus remains unclear, although several studies have provided insights.…”

A major production constraint of lilies is gray mold caused by the necrotrophic fungus Botrytis elliptica. The molecular basis of lily plant resistance to B. elliptica remains largely unexplored. To systematically dissect transcriptomic responses, we constructed four RNA-seq libraries from the leaves of Lilium regale, a promising Chinese wild Lilium species, after B. elliptica infection for 0, 4, 12, or 24 h. The sequence reads were assembled into 96 416 unigenes, of which 7697 were differentially expressed. Profiling analysis revealed changes in gene expression, including 2261 downregulated genes and 3599 upregulated genes. Quantitative real-time polymerase chain reaction analysis of 39 defense-related unigenes confirmed that the transcriptional changes of these genes presented in the RNA-seq data were predominately affected by B. elliptica infection. Key B. elliptica modulated genes played roles in defense responses mediated by phytohormones involved in jasmonate signaling, whereas salicylic acid and ethylene were not involved. Among transcription factors, some WRKYs, MYB, and ethylene responsive factor were clearly upregulated. Additionally, a group of genes encoding known important defense-related proteins, such as receptor-like kinases, antioxidant enzymes, polyphenol oxidase, pathogenesis-related proteins, and proteins associated with phenylpropanoid metabolism, exhibited high transcript abundances. Furthermore, the expressions of selected candidate genes were induced more rapidly and strongly in the resistant genotype than in the susceptible genotype. Taken together, the results provide a better understanding of the defense responses involved in the crosstalk between the lily and B. elliptica and a valuable set of sequence data for gray mold resistant candidate gene discovery.

Pathway analysis represents an effective means of identifying emerging invasive alien species. For plants, a significant number of invasions have been caused by plant species originally voluntary introduced as ornamentals. The pathway analysis for terrestrial ornamental plants imported from East Asia has been undertaken to provide information on the imports and to identify emerging terrestrial invasive alien plants. Data for terrestrial ornamental plants imported from East

“…Lily ( Lilium ) belongs to the perennial herbaceous bulb plant of Liliaceae family, with approximately 110–115 species distributed in the cold temperate zone of the northern hemisphere, especially in East Asia and North America (Du et al., 2014). China has approximately 55 lily species and is an essential wild Lilium distribution center in the world (Jin, Zhang, Yan, Guo, & Niu, 2012).…”

The biochemical properties and thermal inactivation of polyphenol oxidase (PPO) from three main planted lily cultivars in China, namely, Lilium lancifolium Thunb, Lilium brownie var. viridulum, and Lilium davidii var. unicolor cotton were evaluated. Data indicate that the PPO from three cultivars showed two optimum pH levels of 4.0 and 6.5-7.0 and temperature of 15°C and exhibited the highest affinity toward 4-methylcatechol. However, this enzyme did not exhibit monophenolase activity. Thiourea and L-cysteine were more effective than other inhibitors. The enzymatic activity of L. lancifolium Thunb PPO crude extract was higher than that of L. brownie var. viridulum and L. davidii var. unicolor cotton. For thermal inactivation, L. davidii var. unicolor cotton PPO showed the best thermal resistance at 65-75°C, and L. lancifolium Thunb showed stability at 45°C. The deactivation of the three types of PPO followed the first-order reaction kinetics, and the activation energy (E a) was 144.28, 138.00, and 107.12 kJ/mol for L. lancifolium Thunb PPO, L. brownie var. viridulum PPO, and L. davidii var. unicolor cotton PPO, respectively. Practical applications Lilium is an ornamental and edible plant typically used for food and traditional Chinese medicine. Its flowers are used for decoration, and its underground bulbs are rich in various bioactive substances. Fresh lily bulbs easily turn brown and lose economic value during storage and processing. Polyphenol oxidase (PPO) is a crucial molecule involved in the enzymatic browning of fruit and vegetables. In this study, PPO was extracted from three main planted lily cultivars in China. Namely, Lilium lancifolium Thunb, Lilium brownie var. viridulum, Lilium davidii var. unicolor cotton and was partially characterized. The results are of considerable importance to further understand the PPO of lily bulbs and provide guidance for the inactivation of enzymes and the processing of lily bulb juice.
