Nutritional properties and phenolic acid profile of selected Philippine pigmented maize with high antioxidant activity

Ten (10) accessions of pigmented maize collected from the various regions in the Philippines with the highest antioxidant activity were evaluated for several chemical and nutritional parameters such as proximate composition, carbohydrate profile (starch, amylose and amylopectin contents), phenolic acid, mineral (iron and zinc) and food energy contents.

Genetic Structure and Diversity of Banana Bunchy Top Virus (BBTV) in the Philippines

Banana bunchy top virus (BBTV) is an important disease of banana in the Philippines and in other banana-producing countries. This study was conducted to investigate the genetic structure and diversity of Philippine BBTV isolates which remain unexplored in the country. BBTV-infected plant tissues were sampled from banana-growing provinces (i.e., Cagayan, Isabela, Quirino, Batangas, Laguna, Rizal, Quezon, Palawan, Cebu, Leyte, and Davao del Sur) and the partial DNA-R gene of BBTV was sequenced.

In Vitro Lipid-lowering Properties of the Fruits of Two Bignay [Antidesma bunius (L.) Spreng] Cultivars as Affected by Maturity Stage and Thermal Processing

Bignay [Antidesma bunius (L). Spreng] fruit contains an array of polyphenols and information on how these bioactive compounds vary with cultivar type, maturity stage, and process treatment are unclear. Also, the effects of these variations on the lipid-lowering potential of this Philippine indigenous berry have not been reported.

Early Differential Expression of Galactomannan Biosynthesis Genes in ‘Makapuno’ Coconut (Cocos nucifera L.) revealed by the De Novo Assembly and Analysis of Endosperm Transcriptome

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).

Transcriptome Analysis of ‘Philippine Lono Tall’ Coconut (Cocos nucifera L.) Endosperm Reveals Differential Expression of Genes Involved in Oil Biosynthesis

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.

Draft Genome Sequence of Multidrug-Resistant Vibrio parahaemolyticus Strain PH698, Infecting Penaeid Shrimp in the Philippines

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.

Draft Genome Sequence of Vibrio parahaemolyticus Strain PH1339, Which Causes Acute Hepatopancreatic Necrosis Disease in Shrimp in the Philippines

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).
