Whole Genome Sequencing and Biocontrol Potential of ASG80 Against Diseases.

-induced crop diseases, commonly known as "plant plagues", pose a significant threat to global food security. In this study, strain ASG80 was isolated from sisal roots and demonstrated a broad-spectrum antagonistic activity against several species and fungal pathogens. Strain ASG80 was identified as via phylogenetic analysis, digital DNA-DNA hybridization (dDDH), and average nucleotide identity (ANI).

Characterization and Fungicide Sensitivity of That Causes Marginal Leaf Blight in H.11648.

Sisal is an important tropical cash crop in southern China. Unfortunately, it is threatened by various diseases. In 2022, a new disease tentatively named marginal leaf blight disease (MLBD) was first observed in sisal fields across Guangxi and Guangdong provinces, with an incidence rate ranging from 13% to 30%.

Exploring cadmium stress responses in sisal roots: Insights from biochemical and transcriptome analysis.

Sisal is a leaf fiber crop with a high integrated value and a wide range of uses in the application of soil remediation of heavy metal contamination. This study provides a preliminary understanding of how sisal responds to Cd stress and presents a theoretical basis for exploring the potential of sisal in the remediation of Cd-contaminated soils. In this work, the activities of the antioxidant enzymes (SOD, POD, and CAT) of sisal were measured by hydroponics with the addition of CdCl2·2.

First Report of Nigrospora hainanensis Causing Leaf Blight on Brachiaria Griseb in China.

Brachiaria Griseb is an important gramineous forage grown in tropical regions, and also a main grass species uses to restore grasslands in tropical and subtropical regions of China. In August 2022, symptoms of leaf blight were observed on nearly 30% of the Brachiaria forage grass in the base of the Chinese Academy of Tropical Agricultural Sciences, Hainan, China. Symptomatic leaves initially exhibited small, reddish-brown, round or oval spots on their tips, subsequently expanding in size along the leaf margin, and gradually becoming wilted and dry.

The Lesson Learned from the Unique Evolutionary Story of Avirulence Gene of .

Blast, caused by , is one of the most destructive diseases affecting rice production. Understanding population dynamics of the pathogen's avirulence genes is pre-required for breeding and then deploying new cultivars carrying promising resistance genes. The divergence and population structure of was dissected in the populations of southern (Guangdong, Hunan, and Guizhou) and northern (Jilin, Liaoning, and Heilongjiang) China, via population genetic and evolutionary approaches.

Development of a Specific Nested PCR Assay for the Detection of 16SrI Group Phytoplasmas Associated with Sisal Purple Leafroll Disease in Sisal Plants and Mealybugs.

Sisal purple leafroll disease (SPLD) is currently the most destructive disease affecting sisal in China, yet its aetiology remains unclear. In our previous research, it was verified to be associated with phytoplasmas, and nested PCR based on the 16S rRNA gene using universal primers R16mF2/R16mR1 followed by R16F2n/R16R2 was confirmed as the most effective molecular method for the detection of phytoplasmas associated with SPLD (SPLDaP). However, the method has a shortcoming of inaccuracy, for it could produce false positive results.

The complete chloroplast genome of (Gentianales: Rubiaceae).

Coffee is one of the most popular beverages around the world. As one of the best-known coffee species, Liberian coffee ( Bull ex Hiern 1876) has a high resistance to leaf rust, a devasting disease caused by . However, there are few reports on the systematic position and phylogenetic relationship of at the chloroplast (cp) genome level.

Genome-Wide Analysis of the PIN Auxin Efflux Carrier Gene Family in Coffee.

Coffee is one of the most popular beverages around the world, which is mainly produced from the allopolyploid . The genomes of and its two ancestors and have been released due to the development of next generation sequencing. However, few studies on are related to the PIN-FORMED (PIN) auxin efflux transporter despite its importance in auxin-mediated plant growth and development.

Identification and complete genomic sequence of a novel sadwavirus discovered in pineapple (Ananas comosus).

The complete genomic sequence of a putative novel member of the family Secoviridae was determined by high-throughput sequencing of a pineapple accession obtained from the National Plant Germplasm Repository in Hilo, Hawaii. The predicted genome of the putative virus was composed of two RNA molecules of 6,128 and 4,161 nucleotides in length, excluding the poly-A tails. Each genome segment contained one large open reading frame (ORF) that shares homology and phylogenetic identity with members of the family Secoviridae.

De Novo Transcriptome Assembly of H11648 by Illumina Sequencing and Identification of Cellulose Synthase Genes in Species.

Transcriptome Comparison Reveals Distinct Selection Patterns in Domesticated and Wild Agave Species, the Important CAM Plants.

Agave species are an important family of crassulacean acid metabolism (CAM) plants with remarkable tolerance to heat and drought stresses () in arid regions and multiple agricultural applications, such as spirit () and fiber () production. The agave genomes are commonly too large to sequence, which has significantly restricted our understanding to the molecular basis of stress tolerance and economic traits in agaves. In this study, we collected three transcriptome databases for comparison to reveal the phylogenic relationships and evolution patterns of the three agave species.

A comprehensive quantitative phosphoproteome analysis of rice in response to bacterial blight.

Background: Rice is a major crop worldwide. Bacterial blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) has become one of the most devastating diseases for rice.

Function and evolution of Magnaporthe oryzae avirulence gene AvrPib responding to the rice blast resistance gene Pib.

Magnaporthe oryzae (Mo) is the causative pathogen of the damaging disease rice blast. The effector gene AvrPib, which confers avirulence to host carrying resistance gene Pib, was isolated via map-based cloning. The gene encodes a 75-residue protein, which includes a signal peptide.

Stepwise arms race between AvrPik and Pik alleles in the rice blast pathosystem.

A stepwise mutation that occurred in both pathogens and their respective hosts has played a seminal role in the co-evolutionary arms race evolution in diverse pathosystems. The process driven by rice blast AvrPik and Pik alleles was investigated through population genetic and evolutionary approaches. The genetic diversity of the non-signal domain of AvrPik was higher than that in its signal peptide domain.

The isolation of Pi1, an allele at the Pik locus which confers broad spectrum resistance to rice blast.

We report the isolation of Pi1, a gene conferring broad-spectrum resistance to rice blast (Magnaporthe oryzae). Using loss- and gain-of-function approaches, we demonstrate that Pi1 is an allele at the Pik locus. Like other alleles at this locus, Pi1 consists of two genes.
