Enrichment of genomic resources and identification of simple sequence repeats from medicinally important Clausena excavata

GreeningDB: A Database of Host-Pathogen Protein-Protein Interactions and Annotation Features of the Bacteria Causing Huanglongbing HLB Disease

The Citrus genus comprises some of the most important and commonly cultivated fruit plants. Within the last decade, citrus greening disease (also known as huanglongbing or HLB) has emerged as the biggest threat for the citrus industry. This disease does not have a cure yet and, thus, many efforts have been made to find a solution to this devastating condition. There are challenges in the generation of high-yield resistant cultivars, in part due to the limited and sparse knowledge about the mechanisms that are used by the Liberibacter bacteria to proliferate the infection in Citrus plants. Here, we present GreeningDB, a database implemented to provide the annotation of Liberibacter proteomes, as well as the host–pathogen comparactomics tool, a novel platform to compare the predicted interactomes of two HLB host–pathogen systems. GreeningDB is built to deliver a user-friendly interface, including network visualization and links to other resources. We hope that by providing these characteristics, GreeningDB can become a central resource to retrieve HLB-related protein annotations, and thus, aid the community that is pursuing the development of molecular-based strategies to mitigate this disease’s impact. The database is freely available at http://bioinfo.usu.edu/GreeningDB/ (accessed on 11 August 2021).

Leaf transcriptome data of two tropical medicinal plants: Sterculia lanceolata and Clausena excavata

The data presented in this article are associated to the research articles, “DOI: 10.1007/s11295-019-1348-3”, [1]; and “DOI: 10.1007/s13205-018-1162-x” [2]. Clausena excavata Burm. f. and Sterculia lanceolata Cav. are medicinal tree plants [3,4] native to Southeast Asia and China, and most members of both the genus Clausena and the genus Sterculia contain various valuable secondary metabolites with a great potential for drug development. Though many phytochemical studies have been conducted using plant extracts from various parts of these plants [4,5], there are very limited genetic resources available. RNA sequencing of C. excavata and S. lanceolata was conducted using pair-end Illumina HiSeq2500 sequencing system, from which the first de novo transcriptome data were produced for both genus Clausena and Sterculia. Transcriptome shotgun assembly using three different assembly tools [2] generated a total of 16,638 non-redundant contigs (N50, 900 bp) from C. excavata and 7,857 (N50, 423 bp) from S. lanceolata. The data are accessible at NCBI BioProject: PRJNA428402 for C. excavata [2] or PRJNA435648 for S. lanceolata[1].
