Genome-wide identification, functional prediction and expression profiling of long non-coding RNAs in Camelina sativa

Saminathan Subburaj, Yongsam Jeon, Luhua Tu, Yong-Tae Jin, more

Plant Growth Regulation > 2018 > 86 > 1 > 49-63

Long non-coding RNAs (lncRNAs) are a class of RNA regulatory molecules having roles in wide range of biological processes. They have been demonstrated to regulate gene expression at the posttranscriptional and transcriptional levels and to function in stress responses in plants and animals, but nothing is known about lncRNAs in Camelina (Camelina sativa L.), an emerging oil crop. Here, we report the...

Identification of γ-radiation-responsive microRNAs and their target genes in Tradescantia (BNL clone 4430)

Saminathan Subburaj, Hye-Jeong Ha, Yong-Tae Jin, Yongsam Jeon, more

Journal of Plant Biology > 2017 > 60 > 2 > 116-128

MicroRNAs (miRNAs) are endogenous small non-coding RNAs that regulate gene expression at posttranscriptional level. They might regulate tolerance to abiotic stress. However, this has not been studied in Tradescantia (BNL clone 3340), an important bio-indicator for measuring the effect of radiation. Up to date, gamma irradiation (γ-IR) responsive miRNAs and their expressions patterns in plants in response...

Chalcone isomerase-like genes in Tradescantia BNL4430: identification, molecular characterization, and differential expression profiles under Ɣ-radiation stress

Saminathan Subburaj, Hye-Jeong Ha, Nuri Park, Seo-Hee Choi, more

Journal of Plant Biochemistry and Biotechnology > 2017 > 26 > 3 > 330-345

Chalcone isomerase (CHI) is an important catalytic enzyme that converts naringenin (chalcone) to (2S)-naringenin in phenylpropanoid pathway. Here, we performed the first comprehensive molecular genetic study on Chalcone isomerase genes in Tradescantia clone BNL 4430 (designated as TrCHI). We identified seven TrCHIs genes (five with full length and two with partial length) through in silico analysis...

Saminathan Subburaj, Luhua Tu, Yong-Tae Jin, Sangsu Bae, more

Horticulture, Environment, and Biotechnology > 2016 > 57 > 6 > 531-543

Improving crops through plant breeding, an important approach for sustainable agriculture, has been utilized to increase the yield and quality of foods and other biomaterials for human use. Crops, including cereals, vegetables, ornamental flowers, fruits, and trees, have long been cultivated to produce high-quality products for human consumption. Conventional breeding technologies, such as natural...

Molecular characterization and evolutionary origins of farinin genes in Brachypodium distachyon L.

Saminathan Subburaj, Nana Luo, Xiaobing Lu, Xiaohui Li, more

Journal of Applied Genetics > 2016 > 57 > 3 > 287-303

Farinins are one of the oldest members of the gluten family in wheat and Aegilops species, and they influence dough properties. Here, we performed the first detailed molecular genetic study on farinin genes in Brachypodium distachyon L., the model species for Triticum aestivum. A total of 51 b-type farinin genes were cloned and characterized, including 27 functional and 24 non-functional pseudogenes...

Site-directed mutagenesis in Petunia × hybrida protoplast system using direct delivery of purified recombinant Cas9 ribonucleoproteins

Saminathan Subburaj, Sung Jin Chung, Choongil Lee, Seuk-Min Ryu, more

Plant Cell Reports > 2016 > 35 > 7 > 1535-1544

Key message Site-directed mutagenesis of nitrate reductase genes using direct delivery of purified Cas9 protein preassembled with guide RNA produces mutations efficiently in Petunia × hybrida protoplast system. Abstract The clustered, regularly...

Identification of novel stress-induced microRNAs and their targets in Camelina sativa using computational approach

Saminathan Subburaj, Augustine Yonghwi Kim, Sanghyeob Lee, Kyung-Nam Kim, more

Plant Biotechnology Reports > 2016 > 10 > 3 > 155-169

MicroRNAs (miRNAs) are a class of small non-coding, single-stranded RNA sequences that regulate gene expression at the post-transcriptional level and also reported to function in stress responses, but their role has not been studied in Camelina (Camelina sativa L.), an emerging oil crop. In this study, we predicted conserved as well as putative novel miRNAs from a Camelina drought stress cDNA library...

Molecular characterisation and evolution of HMW glutenin subunit genes in Brachypodium distachyon L.

Saminathan Subburaj, Guanxing Chen, Caixia Han, Dongwen Lv, more

Journal of Applied Genetics > 2014 > 55 > 1 > 27-42

Brachypodium distachyon, a small wild grass within the Pooideae family, is a new model organism for exploring the functional genomics of cereal crops. It was shown to have close relationships to wheat, barley and rice. Here, we describe the molecular characterisation and evolutionary relationships of high molecular weight glutenin subunits (HMW-GS) genes from B. distachyon. Sodium dodecyl...

Dynamic development of starch granules and the regulation of starch biosynthesis in Brachypodium distachyon: comparison with common wheat and Aegilops peregrina

Guanxing Chen, Jiantang Zhu, Jianwen Zhou, Saminathan Subburaj, more

BMC Plant Biology > 2014 > 14 > 1 > 1-15

Background Thorough understanding of seed starch biosynthesis and accumulation mechanisms is of great importance for agriculture and crop improvement strategies. We conducted the first comprehensive study of the dynamic development of starch granules and the regulation of starch biosynthesis in Brachypodium distachyon and compared the findings with those reported for common wheat (Chinese Spring,...

iTRAQ‐based quantitative proteomic analysis reveals new metabolic pathways of wheat seedling growth under hydrogen peroxide stress

Pei Ge, Pengchao Hao, Min Cao, Guangfang Guo, more

PROTEOMICS > 13 > 20 > 3046 - 3058

As an abundant ROS, hydrogen peroxide (H₂O₂) plays pivotal roles in plant growth and development. In this work, we conducted for the first time an iTRAQ‐based quantitative proteomic analysis of wheat seedling growth under different exogenous H₂O₂ treatments. The growth of seedlings and roots was significantly restrained by increased H₂O₂ concentration stress. Malondialdehyde, soluble sugar, and proline...

Molecular cloning and characterization of six novel HMW‐GS genes from Aegilops speltoides and Aegilops kotschyi

Chaoying Ma, Yang Yang, Xiaohui Li, Pei Ge, more

Plant Breeding > 132 > 3 > 284 - 289

Six novel high molecular weight glutenin subunits (HMW‐GS) from Aegilops speltoides (SS, 2n = 2x = 14) and Aegilops kotschyi (UUSS, 2n = 4x = 28) were identified by SDS‐PAGE and designated as ASy15*,AKx1*,AKx3*,AKx2.3,AKy20* and AKy8*, respectively. Their complete open reading frames (ORFs) were cloned and sequenced by allele‐specific PCR (AS‐PCR). Sequence comparison demonstrated that these novel...

Molecular characterization and dynamic expression patterns of two types of γ-gliadin genes from Aegilops and Triticum species

Shunli Wang, Xixi Shen, Pei Ge, Jie Li, more

Theoretical and Applied Genetics > 2012 > 125 > 7 > 1371-1384

Gliadins were the major components of wheat storage proteins and determine the extensibility properties of gluten dough. In this work, 19 new full-length γ-gliadin genes were isolated from various Aegilops and Triticum species. Sequence characterization showed that a specific octapeptide and celiac disease (CD)-toxic epitope Gliγ-3 (VQGQGIIQPQQPAQL) were present in the rich glutamine domain and C-terminal...
