A high-quality genome assembly and annotation of Thielaviopsis punctulata DSM102798.

Black scorch disease (BSD), caused by the fungal pathogen Thielaviopsis punctulata (Tp) DSM102798, poses a significant threat to date palm cultivation in the United Arab Emirates (UAE). In this study, Chicago and Hi-C libraries were prepared as input for the Dovetail HiRise pipeline to scaffold the genome of Tp DSM102798. We generated an assembly with a total length of 28.

High-quality genome assembly and annotation of five bacteria isolated from the Abu Dhabi sabkha-shore region.

Objectives: Sabkhas represent polyextreme environments characterized by elevated salinity levels, intense ultraviolet (UV) radiation exposure, and extreme temperature fluctuations. In this study, we present the complete genomes of five bacterial isolates isolated from the sabkha-shore region and investigate their genomic organization and gene annotations. A better understanding of the bacterial genomic organization and genetic adaptations of these bacteria holds promise for engineering microbes with tailored functionalities for diverse industrial and agricultural applications, including bioremediation and promotion of plant growth under salinity stress conditions.

Tapping into Plant-Microbiome Interactions through the Lens of Multi-Omics Techniques.

This review highlights the pivotal role of root exudates in the rhizosphere, especially the interactions between plants and microbes and between plants and plants. Root exudates determine soil nutrient mobilization, plant nutritional status, and the communication of plant roots with microbes. Root exudates contain diverse specialized signaling metabolites (primary and secondary).

The 1-aminocyclopropane-1-carboxylic acid deaminase-producing UAE1 can provide protection from sudden decline syndrome on date palm.

In the United Arab Emirates (UAE), sudden decline syndrome (SDS) is one of the major fungal diseases caused by affecting date palm plantations. To minimize the impact of the causal agent of SDS on date palm, native actinobacterial strains isolated from rhizosphere soils of healthy date palm plants were characterized according to their antifungal activities against DSM 106836 (). Based on their abilities, two promising biocontrol agents (BCAs), namely UAE1 () and UAE1 (), were selected for the production of antifungal compounds and cell wall degrading enzymes (CWDEs), albeit their variations in synthesizing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (ACCD).

Salt flat microbial diversity and dynamics across salinity gradient.

Sabkhas are hypersaline, mineral-rich, supratidal mudflats that harbor microbes that are adapted to high salt concentration. Sabkha microbial diversity is generally studied for their community composition, but less is known about their genetic structure and heterogeneity. In this study, we analyzed a coastal sabkha for its microbial composition using 16S rDNA and whole metagenome, as well as for its population genetic structure.

Biocontrol Potential of Endophytic Actinobacteria against , the Causal Agent of Sudden Decline Syndrome on Date Palm in the UAE.

Thirty-one endophytic streptomycete and non-streptomycete actinobacteria were isolated from healthy date palm root tissues. screening revealed that the antifungal action of isolate #16 was associated with the production of cell-wall degrading enzymes, whereas with diffusible antifungal metabolites in isolate #28, albeit their production of volatile antifungal compounds. According to the 16S rRNA gene sequencing, isolates #16 and #28 were identified as UAE2 (; GenBank Accession #: OK560620) and UAE1 (; OK560621), respectively.

Effectiveness of Augmentative Biological Control of UAE2 Depends on 1-Aminocyclopropane-1-Carboxylic Acid Deaminase Activity against .

To manage stem canker disease on royal poinciana, actinobacterial isolates were used as biological control agents (BCAs) based on their strong inhibitory effects against . UAE2 and UAE1 had the ability to produce antifungal compounds and cell-wall-degrading enzymes (CWDEs). Only , however, restored the activity of 1-aminocyclopropane-1-carboxylate (ACC) deaminase (ACCD).

Molecular Characterization and Disease Control of Stem Canker on Royal Poinciana () Caused by in the United Arab Emirates.

In the United Arab Emirates (UAE), royal poinciana () trees suffer from stem canker disease. Symptoms of stem canker can be characterized by branch and leaf dryness, bark lesions, discoloration of xylem tissues, longitudinal wood necrosis and extensive gumming. General dieback signs were also observed leading to complete defoliation of leaves and ultimately death of trees in advanced stages.

Molecular Identification and Disease Management of Date Palm Sudden Decline Syndrome in the United Arab Emirates.

Date palm orchards suffer from serious diseases, including sudden decline syndrome (SDS). External symptoms were characterized by whitening on one side of the rachis, progressing from the base to the apex of the leaf until the whole leaf dies; while the internal disease symptoms included reddish roots and highly colored vascular bundles causing wilting and death of the tree. Although three spp.

Detection and Management of Mango Dieback Disease in the United Arab Emirates.

Mango is affected by different decline disorders causing significant losses to mango growers. In the United Arab Emirates (UAE), the pathogen was isolated from all tissues sampled from diseased trees affected by . Symptoms at early stages of the disease included general wilting appearance of mango trees, and dieback of twigs.

Chemical Control of Black Scorch Disease on Date Palm Caused by the Fungal Pathogen Thielaviopsis punctulata in United Arab Emirates.

Date palm (Phoenix dactylifera L.) is one of the most important plants grown for its edible fruit. Palm diseases are among the major factors affecting its growth and productivity.
