Pototan BL, Capin NC, Delima AG, Novero AU. 2021. Assessment of mangrove species diversity in Banaybanay, Davao Oriental, Philippines. Biodiversitas 22: 144-153. This study determined mangrove species diversity and community structure in Banaybanay, Davao Oriental, Philippines. Ten 150m long transects plots were laid out perpendicular through the m...

The coconut is an important economic crop in the Philippines which currently ranks as the world's second largest producer. This study characterised and identified endophytes from coconut tissue culture in order to gain an initial understanding of their potential uses as sources of bioproducts. The isolates were evaluated using morphological, bioche...

Davao Region is one of the most agriculturally productive regions in the Philippines. It is the country's top producer of banana and coconut. In this study, light detection and ranging (LIDAR) technology was employed for the accurate assessment of agricultural, coastal and forest resources in Davao Region. A total area of 5799 km² of LiDAR data wer...

The sago palm is an emerging important food and energy source in the Philippines. There is limited information on the nature of its distribution in the Philippines. This study presents a phylogenetic tree hinting of the possible influence of geographical distribution to Internal Transcribed Spacer (ITS) polymorphism in sago palm. Internal Transcrib...

This study assessed mangrove forest diversity in Carmen, Panabo and Tagum, Davao del Norte, Philippines. Among parameters calculated were rank abundance and diversity index. There were 12 species representing 8 families of mangroves in Carmen, 11 species from 9 families in Tagum, and 16 species from 10 families in Panabo, repesctively. Species domi...

Background and Objective: The banana ranks among the top fruits in the world. Production of bananas is beset with problems of pest and disease infestation. The local Philippine cultivar ‘Saba’ h as been reported to possess resistance to major diseases affect ing other banana cultivars. This study assessed fungal species present in the soil rhizos...

Saccharomycopsis (Syn. Endomycopsis) bubodii 2066 is an isolate from bubod, a starter used in making rice wine in northern Philippines. We have shown that the yeast has amylolytic activity on raw sago starch. In our attempt to identify the putative raw starch-digesting amylase in S. bubodii, we determined the cDNA sequence of a glucoamylase gene. O...

The Philippines has embarked on a detailed nationwide natural resource inventory using LiDAR through the Phil-LiDAR 2 Program. This 3-year program has developed and has been implementing mapping methodologies and protocols to produce high-resolution maps of agricultural, forest, coastal marine, hydrological features, and renewable energy resources....

The value of sago palm (Metroxylon sagu Rottb.) as a high starch yielding crop has not been fully realized yet but at risk to human-mediated and environmental threats that necessitate its conservation. Attempts were made to investigate cryopreservation as an option for long-term storage of sago palm zygotic embryos using simple desiccation techniqu...

Endophytic bacteria are novel sources of beneficial compounds such as plant growth regulators and antibiotics. Nine bacterial isolates were obtained from sago palm tissue culture. Selected candidates were those colonies observed to have originated from the base of the explants. Eight of the isolates were Gram- negative bacilli (SEB 001, 002, 003, 0...

The formation of spine is a primitive evolutionary event in plants. In sago palm, studies reporting the results of RAPD and AFLP analyses showed lack of significant genetic variation among spiny and non-spiny plants. This observation led us to the hypothesis that spine formation may be an epigenetic event. The inheritance of spine formation is of h...

Sago palm is an emerging important crop in the Philippines. Earlier investigations on spiny and spiny sago palm ecotypes in Southeast Asia employed isozyme, RAPD and AFLP analyses and found no significant genetic variations. This observation led to the hypothesis that spine formation may be an epigenetic event. Spine formation is of high interest t...

Metroxylon sagu (sago palm) has long been considered as one of the oldest sources of food for humans because of the presence of huge amounts of starch in its trunk. Sago palm is an important food source in Papua New Guinea, Malaysia and Indonesia. Sago palm is increasingly gaining acceptance as an important food source in southern regions of Vietna...

The o-acetylserine (thiol) lyase (OAS-TL) gene is part of the plant sulfate assimilation pathway. The synthesis of cysteine, the first product of the pathway containing organic sulfur, has been previously observed to be dependent on the availability of sulfur and activity of OAS-TL. In this study, the ability of Vicia sativa L. to alter its metabol...

This study investigated the role of osmotic potential of media on the early growth stages of sago palm in vitro. There were significant effects on the growth rate of explants after four weeks of culture under different sucrose and D-sorbitol combinations. A modified Murashige and Skoog (MS) medium supplied with 22.5 g sucrose and 7.5 g sorbitol whi...

The production of cysteine is the first major significant event in the plant sulfate assimilation process. Cysteine is a precursor of many important biological molecules. Two of the enzymes involved in cysteine biosynthesis are beta-cyanoalanine synthase (CAS) and o-acetylserine (thiol) lyase, members of the Beta-subsituted alanine synthase (Bsas)...

A putative o-acetylserine (thiol) lyase (OAS-TL; EC 2.5.1.47) gene was successfully cloned and characterized from vetch, Vicia sativa L. cv. Blanche Fleur. The gene, named Voas-tl5 (GenBank Accession No. DQ456491) had a cDNA length of 871 bp with its open reading frame coding for a polypeptide of 68 amino acid residues. In semi-quantitative RT-PCR,...

Field experiments were conducted to evaluate and compare the yield and agronomic characteristics of anther-culture-derived (AC) lines in rice and the parents under saline and nonsaline soil conditions. The yield stability of two entries was also evaluated by comparing their performance under two distinct nonsaline soil environments. The test entrie...
