| 英文摘要 | Indigo dyes have been used for coloration of textiles science antiquity worldwide. The advantages of natural indigo dye are kind of irreplaceable environmental compatibility and artistic creativity. In addition to its application to textile dyeing, indigo/indigotin (the main pigment component of indigo dyes) can also be used as a kind of food color and color polyester medical sutures, and as a medical indicator for intravenously. Nowadays, indigo dye is still considered as one of the most popular blue colorants such as blue jeans. At present, 95% of indigo in the markets is chemically synthesized. However, the raw material of chemically synthesized indigo comes from petroleum cracking products, which is unsustainable resource. Therefore, it is very important to find alternative industrial materials from plants species, which is of great significance for the transformation of textile industry to "green textile" under the background of ecological civilization construction policy. Firstly, we used ethnobotanical methods to investigate and document the indigo-yielding plant species in China. Combined with the ethnobotanical quantitative index, we screened out that S. cusia was the most potential indigo-yielding plant species. Therefore, our follow-up studies focused on S. cusia. Applaying ecology, cutting-edge genomics and analytical chemistry, the geographical distribution and molecular basis of indigo biosynthesis in S. cusia were further studied. The main results are as following: 1) Ethnobotanical surveys of the indigenous knowledge on natural indigo dye in China From December 2017 to January 2020, we conducted ethnobotanical surveys in Yunnan, Guizhou, Guangxi and Hainan Province. Totally 25 villages, 5 traditional markets and 12 mills were visited. We performed simi-structure interview with 407 informants, who were selected by using the snow ball sampling methods. Five indigo-yielding plant species were documented. The five plant species were Strobilanthes cusia (Nees) Kuntze, Wrightia laevis Hook.f, Indigofera tinctoria Linn, Indigofera suffruticosa Mill, and Persicaria tinctoria H. The major process of indigo extracting method was almost the same among the eight nationalities (Buyi, Hani, Han, Landian Yao, Li, Miao, Shui, and Heiyi Zhuang nationalities). S. cusia was the most potential indigo-yielding plant species based on the values of Mention index (QI), Preference Ranking (PR), and Availability index (AI). 2) Geographic distribution predicting and the main factors influencing its geographical distribution After removing the duplication and geography proofreading, we collected 766 occurrence records of S. cusia from the plant database, literature, and field surveys. Then we used the wild occurrences and environmental variables (bioclimatic variables, human activities variables, and land form variables) as the input layers to predict the suitable habitats of S. cusia by using MaxEnt modelling. Our results indicated that the suitable habitat |
