Ao Wang, Wujisguleng Wujisguleng, Yujing Liu, Yue Liu, Chunlin Long
Open Journal of Genetics (OJGen) , 2013, DOI: 10.4236/ojgen.2013.32011

Astragalus mongholicus (Fabaceae) is a perennial herb and a widely used medicinal plant in traditional Chinese medicine (TCM) known as Radix Astragali (Huangqi). It was reported to have hepatoprotective, cardioprotective, antidiabetic, antiaging, sedative and immunopotentiating effects, and could also be used as an adjuvant medicine during cancer therapy. Until now, there is only a little research on its population genetics and no report on development of microsatellite loci for this plant. In this study, a microsatellite-enriched genomic DNA library of A. mongholicus was developed and screened to identify marker loci. Ten polymorphic loci were isolated and analyzed by screening 30 individuals. The number of alleles per locus ranged from 4 to 19, with an average of 12.3 alleles per locus. The observed heterozygosity (HO) and the expected heterozygosity (HE) ranged from 0.367 to 1.000 and from 0.395 to 0.912, respectively. The polymorphism information content (PIC) varied from 0.361 to 0.888, with an average of 0.762. This is the first report on characterization of microsatellite loci for A. mongholicus, and these markers will be useful for population genetics and molecular ecology studies of this plant.

Blending Sensor Scheduling Strategy with Particle Filter to Track a Smart Target  [PDF]
Bin LIU, Chunlin JI, Yangyang ZHANG, Chengpeng HAO
Wireless Sensor Network (WSN) , 2009, DOI: 10.4236/wsn.2009.14037
Abstract: We discuss blending sensor scheduling strategies with particle filtering (PF) methods to deal with the prob-lem of tracking a ‘smart’ target, that is, a target being able to be aware it is being tracked and act in a manner that makes the future track more difficult. We concern here how to accurately track the target with a care on concealing the observer to a possible extent. We propose a PF method, which is tailored to mix a sensor scheduling technique, called covariance control, within its framework. A Rao-blackwellised unscented Kal-man filter (UKF) is used to produce proposal distributions for the PF method, making it more robust and computationally efficient. We show that the proposed method can balance the tracking filter performance with the observer’s concealment.

Ethnobotanical review of food uses of Polygonatum (Convallariaceae) in China
Wujisguleng Wujisguleng,Yujing Liu,Chunlin Long
Acta Societatis Botanicorum Poloniae , 2012, DOI: 10.5586/asbp.2012.045
Abstract: According to our literature survey, fifteen species in the genus Polygonatum (Convallariaceae) have been used as food in China. Five main categories of use (drinks, snacks, vegetables, staple food and seasoning) were found. The plants from this genus are used mainly as vegetables. Rhizomes are the main parts used. The categories of use and diverse preparation methods have some similarities with those in other countries. Among all the recorded species, Polygonatum sibiricum and P. odoratum are the most commonly consumed species in China. Local people from different places have their own unique preparation methods and customs. However, the use of Polygonatum still remains at the level of family consumption, and the resources have not been fully used yet. We proposed ideas for further exploitation and conservation of edible Polygonatum species, and suggested fur- ther research, e.g. on the nutritional properties of all recorded edible species. It is believed that there is still plentiful traditional knowledge about food uses of Polygonatum to be documented in China.
Food uses of ferns in China: a review
Yujing Liu,Wujisguleng Wujisguleng,Chunlin Long
Acta Societatis Botanicorum Poloniae , 2012, DOI: 10.5586/asbp.2012.046
Abstract: Edible ferns are some of the most important wild vegetables in China. This paper reviews their food uses. The history of eating ferns in China may go back as far as 3000 years. An ethnobotanical inventory of edible ferns was created, with 52 species (including 4 varieties), which were traditionally used. The potential species number of edible ferns was estimated as 144 species (including 4 varieties). The cuisines, products and chemical components of ferns were also summarized. The most commonly eaten fern, Pteridium aquilinum var. latiusculum, was discussed in terms of its toxicity, massive productivity and development strategies. Suggestions and recommendations were proposed for the future development of edible ferns in China.

Journal of Ethnobiology and Ethnomedicine , 2009, DOI: 10.1186/1746-4269-5-15
Abstract: After literature surveying, four local townships were selected to carry out the field investigation. Three local healers were interviewed as key informants. The methods of ethnobotany, anthropology and participatory rural appraisal (PRA) were used in the field surveys. Plant taxonomic approach was adopted for voucher specimen identification.Sixty-eight medicinal plant species in 64 genera of 40 families were recorded and collected. Among them, 23 species were found to have medicinal values that have not been recorded in any existing Tibetan literatures before, and 31 species were recorded to have traditional prescriptions. Moreover, the traditional preparations of each species and some folk medicinal knowledge were recorded and analyzed. These traditional prescriptions, preparations, new medicinal plants and folk medicinal knowledge and principles were discovered and summarized by local traditional Tibetan healers through times of treatment practices, and were passed down from generation to generation.As a part of the cultural diversity of Tibetan community, these traditional medicinal knowledge and experiences may provide data and information basis for the sustainable utilization and development of Tibetan medicine, and may contribute to the local economic development. However, for many reasons, they are disappearing gradually as time goes by. Our study showed that there were abundant traditional Tibetan medicinal prescriptions and using methods. It implies that more Tibetan medicinal plants and traditional knowledge can be discovered. Further research should be done to save the wealth of these traditional medicinal knowledge and experiences before they are dying out.There are nearly 2000 ethnic groups in the world, and almost every group has its own traditional medicinal knowledge and experiences to depend on [1]. China is a multi-racial country with 56 nationalities, of which 55 in over 18 provinces are officially recognized as ethnic minorities. The various and
Phylogenetic analysis and classification of the Brassica rapa SET-domain protein family

BMC Plant Biology , 2011, DOI: 10.1186/1471-2229-11-175
Abstract: Here we identified 49 SET-domain proteins from the recently sequenced Brassica rapa genome. We performed sequence similarity and protein domain organization analysis of these proteins, along with the SET-domain proteins from the dicot Arabidopsis thaliana, the monocots Oryza sativa and Brachypodium distachyon, and the green alga Ostreococcus tauri. We showed that plant SET-domain proteins can be grouped into 6 distinct classes, namely KMT1, KMT2, KMT3, KMT6, KMT7 and S-ET. Apart from the S-ET class, which has an interrupted SET domain and may be involved in methylation of nonhistone proteins, the other classes have characteristics of histone methyltransferases exhibiting different substrate specificities: KMT1 for H3K9, KMT2 for H3K4, KMT3 for H3K36, KMT6 for H3K27 and KMT7 also for H3K4. We also propose a coherent and rational nomenclature for plant SET-domain proteins. Comparisons of sequence similarity and synteny of B. rapa and A. thaliana SET-domain proteins revealed recent gene duplication events for some KMTs.This study provides the first characterization of the SET-domain KMT proteins of B. rapa. Phylogenetic analysis data allowed the development of a coherent and rational nomenclature of this important family of proteins in plants, as in animals. The results obtained in this study will provide a base for nomenclature of KMTs in other plant species and facilitate the functional characterization of these important epigenetic regulatory genes in Brassica crops.Epigenetic regulation acts through heritable changes in genome function that occur without a change in DNA sequence. One well-known epigenetic mechanism is through posttranslational covalent modifications of histones; these modifications include acetylation, methylation, ubiquitylation and others, and form the basis of the 'histone code' for gene regulation [1]. Histone lysine methylation plays a pivotal role in a wide range of cellular processes including heterochromatin formation, transcriptional regul

Journal of Ethnobiology and Ethnomedicine , 2009, DOI: 10.1186/1746-4269-5-13
Abstract: The approaches of ethnobotany, anthropology, and participatory rural appraisal were used in the field surveys. Twenty-two informants in four counties were interviewed during eight field trips. Medicinal plant specimens were identified according to taxonomic methods.One hundred sixteen medicinal plant species were found to be useful by the local people in the treatment of various diseases or disorders, especially those relating to trauma, gastrointestinal disorders and the common cold. Among these 116 species, 25 species (21.55%) were found to have new curative effects and 40 species (34.48%) were recorded for their new preparation methods; 55 different species were used in treating wounds and fractures, and 47 were used to treat gastrointestinal disorders. Traditional Yi herbal medicines are characterized by their numerous quantities of herbaceous plants and their common preparation with alcohol.Totally 116 species in 58 families of medicinal plants traditionally used by the Yi people were inventoried and documented. The characteristics of medicinal plants were analyzed. Some new findings (such as new curative effects and new preparation methods) were recorded These newly gathered ethnobotanical and medicinal data are precious sources for the future development of new drugs, and for further phytochemical, pharmacological and clinical studies.Chuxiong Prefecture, located in the north of middle Yunnan Plateau (24°13' – 26°30' N, 100°43' – 102°43' E), has numerous high mountains, deep canyons, and large and small rivers. Mountainous land in Chuxiong occupies over 90% of its total territory. Chuxiong's climate is considered a sub-tropical and moist plateau monsoon climate, primarily affected by two air currents: a warm, dry current from northern Africa, the Middle-East and the subcontinent of India during winter and a cool, moist current from the Indian Ocean and Bay of Bengal during summer. The climate of Chuxiong is characterized by long spring and autumn and short su
