Atmospheric nanoparticles(PM50%)with minor contribution from EC(3%-12%).The higher fraction of carbonaceous components was found in the particulates with smaller sizes,and lignin content may relate to concentration of pyrolyzed organic carbon(PyOC)resulting in the differences of OC/EC *** emit-ted from burning palm fiber and rice stubble showed high values of OC/EC and also high ***-carbonaceous components such as Cl^(-),Cr,Ca,Cd,Ni,Na and Mg may be useful as source indicators,but they did not show any correlation with the size of PM.

Development of Starfruit Simple Sequence Repeat (SSR) Using Next Generation Sequencing

引用

Journal of Food Science and Engineering 2019年第3期9卷 95-121页

作者： Khairun hisam Nasir Muhammad Fairuz Mohd Yusof Mohd Shahril Firdaus Siti Zainab Jantan Mira Farzana Mohamad Moktar Siti Norsaidah Ibrahim Noor Baiti Abdul Aziz Joanna Cho Lee Ying Centre for Molecular Marker Discovery and Validation (CMDV) Agri-Omic dan Bioinformatics Biotechnology and Nanotechnology Research Centre Malaysian Agricultural Research and Development Institute (MARDI) 43400 Serdang Selangor Malaysia Horticulture Research Centre Headquarters Malaysian Agricultural Research and Development Institute (MARDI) 43400 Serdang Selangor Malaysia

Starfruit (Averrhoa carambola L.) is an important fruit for Malaysian export and great attention has been made to improve starfruit fruit quality at Malaysian Agricultural Research and Development Institute (MARDI). The current study used next generation sequencing (NGS) technologies to develop starfruit simple sequence repeat (SSR) from 2 varieties namely B11 and B17 using Illumina HiSeq. The pre-processed reads were de novo assembled to generate approximately 75,000 and 74,000 scaffolds respectively. Total genome size for B11 and B17 were around 345 Mbp and 342 Mbp based on K-mer distribution analysis. In-silico microsatellite mining of each variety has identified more than 17,000 SSR in B11 and B17 respectively. Dinucleotides were the most abundant, accounting for more than 70% of all SSR and repeat motif GA (49%) was most common. A total of 239 SSR primer pairs were designed from contigs larger than 350 nucleotides and tested for amplification. The 30 polymorphic SSRs were used to DNA fingerprint of 12 starfruit hybrids. Polymorphism information content (PIC) ranged from 0.1411 to 0.6838, with an average of 0.3919. The Unweighted Pair-Group Method for Arithmetic Averages (UPGMA) dendrogram clustered 12 starfruit accessions into 2 groups.
