Assessment of bacterial communities of termite workers attacking Ironwood trees () in Guam for the presence of Ironwood tree decline-associated pathogens.

The Ironwood tree () holds a significant ecological role in Guam where a decline in Ironwood trees was first documented in 2002. Studies have linked the Ironwood tree decline (IWTD) to bacteria from the complex and wetwood bacteria, specifically and . Presence of termites was first found to be associated with IWTD in 2010; however, the role of termites in IWTD is still not clear.

Development and Evaluation of Real-Time Quantitative PCR Assays for Detection of Causing Brown Root Rot Disease.

Brown root rot disease (BRRD) is a highly destructive tree disease. Early diagnosis of BRRD has been challenging because the first symptoms and signs are often observed after extensive tissue colonization. Existing molecular detection methods, all based on the internal transcribed spacer (ITS) region, were developed without testing against global isolates, other wood-decay fungi, or host plant tissues.

Taxonomic profiling of Nasutitermes takasagoensis microbiota to investigate the role of termites as vectors of bacteria linked to ironwood tree decline in Guam.

The ironwood tree (Casuarina equisetifolia, family Casuarinaceae), an indigenous agroforestry species in Guam, has been threatened by ironwood tree decline (IWTD) since 2002. Formation of bacterial ooze by the wilt pathogen from the Ralstonia solanacearum species complex and wetwood bacteria (primarily Klebsiella species) has been linked to IWTD. In addition, termite infestation of trees was statistically associated with IWTD.

Next-generation sequencing dataset of bacterial communities of workers associated with Ironwood trees () in Guam.

Ironwood trees () in Guam have been suffering from Ironwood Tree Decline (IWTD) since 2002. Putative plant pathogenic bacteria such as and species were identified in the ooze of declining trees and considered to be linked to IWTD. In addition, termites were found to be significantly associated with IWTD.

Translocation of Fungicides and Their Efficacy in Controlling , the Cause of Brown Root Rot Disease.

Brown root rot disease (BRRD), caused by , is an important tree disease in tropical and subtropical areas. To improve chemical control of BRRD and deter emergence of fungicide resistance in . , this study investigated control efficacies and systemic activities of fungicides with different modes of action.

Complete Genome Sequences of Tomato Leaf Curl Guam Virus, a Novel Tomato-Infecting Begomovirus from Guam, USA.

Genome sequences of a novel begomovirus infecting tomato on Guam were obtained using primer-walking and sequencing. The complete genome sequences are 2,750 nucleotides long with a typical monopartite organization and display less than 91% nucleotide sequence identity to other begomoviruses. A provisional name, tomato leaf curl Guam virus (ToLCGuV), is proposed.

Morphological and Molecular Species Identification of Termites Attacking Ironwood Trees, Casuarina equisetifolia (Fagales: Casuarinaceae), in Guam.

Ironwood trees (Casuarina equisetifolia subsp. equisetifolia L.) are ecologically and economically important trees in tropical and subtropical regions of the Indo-Pacific.
