Research - Genes and Genomes

{slider-nested What It Is About}

The extraordinary progress that has been made in sequencing technologies in the past few years has revolutionized research in genomics studies. During the last decade, the advent of genome sequencing technologies has allowed the deciphering of genome sequences of more than 2,000 individuals of eukaryotes as well as more than 10,000 individuals of prokaryotes. Today’s complex genomic research questions have propelled sequencing technologies to even greater advancements. Some approaches deliver unprecedented throughput and speed, generating a wealth of data that greatly improves the analysis of increasingly complex phenotypes. Alternatively, other approaches now aim to produce long reads that enable the efficient de novo sequencing or characterization of genome of nontraditional species. These and other strategies constitute an opportunity for researchers to understand the genetic basis underlying phenotype and to study biological systems in ways never before possible. Here, at the Centre for Chemical Biology, USM, we characterize the genomes of individual organisms and systems of organisms from the Malaysian environment and study their genes and functions.

Genome of ‘mini-fish’

Miniaturization, or the phenomenon of extreme body size reduction compared to other species in the same lineage, is frequently encountered in fishes. Fishes maturing at sizes less than 20 mm have been termed ‘miniature fish’ or ‘mini-fish’. Miniaturized taxa are often paedomorphic, resulting from truncation of development combined with accelerated maturation. Features of mini-fish could also include the tendency to lose bones and scales or having a poorly ossified, largely cartilaginous skeleton. Paedocypris, which has been described as the world’s smallest vertebrate, is a prominent example among ‘mini-fish’. The sequencing of Paedocypris spp. the genome provides an opportunity for understanding miniaturization evolution in teleost and the study of traits associated with the evolution of small size in ‘mini-fish’.

Iso-Seq of terrestrial crab

Lipid metabolism is critical for proper function in animals. So far, lipid metabolism in a crustacean is poorly understood. Nothing is known about the ability of crustacean to biosynthesis polyunsaturated fatty acids. It is speculated that this capacity is related to the niche of the particular crustacean species. Using the PacBio Iso-seq method, we identify genes related to the biosynthesis of polyunsaturated fatty acids in terrestrial crab and to gain a full picture of lipid metabolism.

Microbiome of oral mucus in tilapia fish

Many species of teleost fish exhibit quite an elaborate form of parental care. Species of Oreochromis (tilapia fish) are mouth brooders; female parents hold and incubate the eggs in their buccal cavity for several days. Fry remain in the females’ mouth through yolk-sac absorption. Apart from the protection and transportation of the young, it is unclear if mouthbrooding provides additional advantages to embryos during incubation. Studies of the microbiome have the potential to reveal important oral mucosal evolutionary processes in Oreochromis sp. and discover symbiotic bacteria that can be used in aquaculture to increase the survival of the young.

Metagenomics insight into microbial communities from the best-managed mangrove soil

Matang Mangrove Forest Reserve (MMFR) s been acknowledged as the best sustainably-managed mangrove forest in the world. Metagenomic data was obtained from two sampling sites at MMFR with distinct features: the Productive Zone and Virgin Jungle Forest. The former zone is designated for tree harvesting while the latter is a pristine area. Matang mangrove metagenomes provide insights into managed mangrove microbiome and serve as important resources for the mining of bacterial species and enzymes involved in litter processing.

The rubber tree genome - What it tells?

1. Genome information reveals possible contributors to rubber tree's capacity to produce a high level of latex.
The expansion of rubber biosynthesis-related genes (cis-prenyltransferase, small rubber particle protein and rubber elongation factor) in the genome and the high expression of these in latex are possible reasons for rubber tree's capacity to produce a large amount of latex.
2. Cap analysis gene expression (CAGE) results show tissue-specific transcription profiles of rubber biosynthesis related genes.
Tissue-specific transcriptions of genes are possible alternative means of transcriptional regulation.
3. Comparative genomic analysis indicates conserved synteny between genomes of the rubber tree, cassava, castor bean and jatropha.
Rubber tree gene blocks showed one-to-one, one-to-two and one-to-three synteny relationships with their orthologues in jatropha, cassava and castor bean, respectively.

The polysaccharide-degrading marine bacterium, Persicobacter sp. CCB-QB2

Numerous bacteria isolated from the marine environment are known for their agarolytic property. These agarolytic microorganisms produce agarases to hydrolyze and metabolize agar as carbon and energy sources. Persicobacter sp. CCB-QB2, isolated from seaweed collected from the coastal area of Penang, was found to exhibit diauxic growth in the presence of two nutrients: tryptone and agar. Whole-genome and transcriptome sequencing were performed to study the diauxic growth in strain CCB-QB2.

Agar hydrolyzing activity from culture supernatant: (a) culture supernatant with agar; (b) culture supernatant without agar.

Novel Mangrovimonas-like strains isolated from estuarine mangrove sediment

Three Mangrovimonas-like strains, TPB4^T (=LMG 28913^T, = JCM 30882^T), ST2L12^T(=LMG 28914T, =JCM 30880^T) and ST2L15^T(=LMG 28915T,=JCM 30881^T) were isolated from estuarine mangrove sediment of Matang Mangrove Forest. Genome information of these isolates reveals xylan and arabaian utilization genes that are not reported in other Mangrovimonas.

The marine predatory bacterium, Aureispira sp. CCB-QB1

The genus Aureispira is known for its predatory lifestyle that preys on other marine bacteria via 'ixotrophy'. Aureispira sp. strain CCB-QB! was isolated from the coastal area of Penang, Malaysia and selected for genome sequencing as there was no genome information available so far from the genus Aureispira. Analysis of the genome reveals pathways for polyunsaturated fatty acid and diterpenoid biosynthesis.
