“…China is the biggest producer of longan in terms of both cultivation area (470000 ha) and total production (610000 tons) (Yaounde, 2011). For more than a century, it has been used in Chinese medicinal practices for health benefits, such as to enhance blood metabolism, increase immunity, to treat insomnia and to improve learning and memory retaining capacity (Yang & He et al, 2008;Park et al, 2010). Besides all of the above mentioned eminent advantage, longan exhibits great antiaging impact, anti cancer activities and antioxidant property .…”

Longan is one of several subtropical and climateric fruit tree of South East Asia having economic and medicinal importance. To understand the mechanism behind altered expression of genetic variants towards various complex diseases, transcriptome analysis is pivotal in present biological scenario. Availability of transcriptomic data of longan facilitates its further functional genomics analysis, differential gene expression analysis and progressive research on the plant varieties of similar family belonging to Indian subcontinent. In the present study, a total number of 90,762,826 mixed paired end sequence reads from 7 different tissues of longan transcriptome (ID: SRR2864836) and 64,876,528 reads for longan embryogenic callus (EC) transcriptome (ID: SRR412534) were downloaded from SRA database, NCBI using SRA Tool Kit. A total number of 9,304 and 10,679 contigs (including scaffolded regions) were assembled from the longan and longan-EC clean reads. Cloud blast search was performed against multiple protein and nucleotide databases at NCBI to explore the mechanistic insights, of the longan transcriptome. A total 9,304 contigs/ putative transcripts were classified into 10 major biological processes, 30 GO functional groups, 08 various cellular components and 139 KEGG pathways. In blast analysis against Nr database, database of Arabidopsis thaliana, Zea mays and Oryza sativa 33 contigs were reported for possessing disease resistant proteins. Additionally differential gene expression analysis between longan and longan-EC transcripts showed a total of 34 genes to be highly upregulated and 26 downregulated genes. Thus our study paves way for further research to improvise and utilize its economic and medicinal characteristics of longan as reference in context to Indian plants viz. Litchi chinensis, Arytera divericata, Schleichera oleosa (Lour.) etc.

“…The alcohol-soluble extract of Longyanrou, containing significant amounts of phenolic compounds, exhibits great anti-oxidant and anticancer functions [4]. Both the water-and alcohol-soluble extracts can enhance learning and memory, and their effects are mediated, in part, by brain derived neurotrophic factor expression, immature neuronal survival and anti-oxidant activity [10,11]. …”

“…Despite its own high production of the crop, China is a net importer of D. longan. As a traditional herb, longan fruit is used for enhancing memory (Park et al, 2010), promoting blood metabolism, relieving insomnia, and preventing amnesia (Yi et al, 2011). In addition, its secondary metabolic products have been shown to have antioxidative (Okuyama et al, 1999;Rangkadilok et al, 2005Rangkadilok et al, , 2007Sun et al, 2007;Jiang et al, 2009), antiobesity , anticancer (Chung et al, 2010), antityrosinase (Prasad et al, 2010), and immunomodulatory activities (Su et al, 2010;Zhong et al, 2010;Yi et al, 2011).…”

ABSTRACT. Dimocarpus longan Lour. is an edible and traditional herb in China, commonly referred to as longon. An improved randomly amplified polymorphic DNA (RAPD) protocol was here developed in order to determine the geographical origins of D. longan samples collected from 5 provinces in the southern and southwestern areas of China, including Sichuan, Hainan, Fujian, Guangdong, and Guangxi. Generally, the improved RAPD method generated good fingerprinting of the 5 samples using the selected 17 primers. In particular, primers SBS-A5, SBS-A13, SBS-I9, SBS-I20, SBS-M1, and SBS-Q12 produced distinguishable bands that clearly separated all 5 cultivars, suggesting that there are variations in RAPD genetic sites among the samples. The similarity index ranged from 0.69 to 0.76. The Sichuan and Hainan clades clustered together with a 0.73 similarity index. The Guangxi and Fujian clades clustered together with a 0.76 similarity index, and they formed the sister clade to the Sichuan/Hainan clade with a 0.71 similarity index. The Guangdong clade was in a basal polytomy with a 0.70 similarity index. Based on the abundant DNA polymorphisms, these longan accessions are distinguishable using our improved RAPD technique. Therefore, RAPD analysis is an effective technique in distinguishing the geographical origins of D. longan. Moreover, the improved method could also be employed for a variety of applications including genetic diversity and fingerprinting analyses.
