This study established the DNA barcodes of 19 economically important Philippine sea cucumbers belonging to Class Holothuroidea under Phylum Echinodermata using the cytochrome c oxidase I (COI) gene.
Makapuno is a coconut cultivar with a naturally overproliferating solid endosperm almost filling the nut cavity. At 6-7 months after pollination (MAP), makapuno solid endosperm is phenotypically indistinguishable from the normal type Laguna Tall while at 8-9 MAP makapuno starts to soften and thicken in contrast to the hard and compact appearance of the normal. Here, the expression profiles of 6-7 and 8-9 MAP de novo assembled RNA Sequencing (RNA-Seq) transcriptomes of normal and makapuno were analyzed, and corresponding stages were compared to determine the differentially expressed genes (DEGs).
The ‘Philippine Lono Tall’ (PLNT) is a variant of the more common ‘Philippine Laguna Tall’ (LAGT), which produces fruits with soft endosperm and reported higher fat content. To understand patterns of fatty acid (FA) and oil accumulation in LAGT and PLNT fruits, transcriptomes of 6–7 month-old endosperm samples were analyzed by RNA-Seq. Quantitative PCR was performed to analyze the differential expression of selected genes related to oil biosynthesis. Further, oil samples from the PLNT endosperm were analyzed to determine their FA composition across developmental stages.
This seminar features the PGC hosted Balik Scientist Dr. Nomar Waminal who will be presenting his talk on “Cytogenetics in Plant Breeding: Conservation and Evolution in the Post-Genomics Era”. Dr. Waminal is currently serving as a Research Professor under the Chromosome Research Institute at Sahmyook University, Seoul, Republic of Korea. He was a Samsung Global Scholar and received his Ph.D. in Crop Science and Biotechnology from Seoul National University.
The emergence of multidrug-resistant bacterial strains in diverse settings has been reported globally. In the Philippine shrimp aquaculture industry, antibiotics are used for the treatment of bacterial diseases during the production cycle. We report the draft genome of Vibrio parahaemolyticus PH698, a multidrug-resistant strain isolated from a Philippine shrimp farm.
Acute hepatopancreatic necrosis disease (AHPND), which affects multiple shrimp species, including the economically important Penaeus monodon and Penaeus vannamei, is characterized by massive sloughing of the epithelial cells of the hepatopancreas to the point of atrophy (1).
The release of the first human reference genome in 2003 marked the beginning of the post-genomics era when genetics progressed beyond gene-centered analyses to a myriad of omics approaches. Genome sequencing technologies have advanced dramatically from Sanger, second/next-generation, to third-generation sequencing platforms. Also, genome assembly methods and tools have evolved contemporaneously, resulting in a dramatic drop in genome assembly cost. Consequently, more than 360 plant species’ genomes have been assembled ever since the first plant genome, Arabidopsis thaliana, was published in 2000.
In recent years, genetics and genomics has played an important role in facilitating the genetic improvement of plants. Different tools have been developed to examine the structure, function, and properties of genes controlling complex traits. The genetic diversity of germplasm found in existing gene banks through different breeding populations such as core collections, nested association mapping panels, mutants, recombinant inbred lines, and multiparent advance generation intercross populations in germplasm banks served as sources of desirable alleles for plant breeding.
The Strategic Planning with the PGC Agriculture team was facilitated by PGC’s newly appointed Deputy Executive Director, Dr. Raul Destura. The activity was initiated by the PGC main office in order to weave the 6-year sustainability plan of the entire PGC.
In an article from the UP MPRO, PGC Program Director for Agriculture, Livestock, Fisheries, and Forestry Dr. Ma. Anita M. Bautista is featured as a transcriptomics expert at the UP NIMBB and PGC.
