Role of long non-coding RNA in regulatory network response to Liberibacter asiaticus in citrus.

Long non-coding RNAs (lncRNAs) serve as crucial regulators in plant response to various diseases, while none have been systematically identified and characterized in response to citrus Huanglongbing (HLB) caused by Liberibacter asiaticus (Las) bacteria. Here, we comprehensively investigated the transcriptional and regulatory dynamics of the lncRNAs in response to L. Samples were collected from leaf midribs of Las- and mock-inoculated HLB-tolerant rough lemon () and HLB-sensitive sweet orange () at week 0, 7, 17, and 34 following inoculation using Las+ budwood of three biological replicates in the greenhouse.

Phenotypic and Genetic Variation in Morphophysiological Traits in Huanglongbing-Affected Mandarin Hybrid Populations.

Huanglongbing (HLB) caused by ' Liberibacter asiaticus' (Las) is the most costly disease for the global citrus industry. Currently, no effective tools have been found to control HLB.

Histone Acetyltransferases and Deacetylases Are Required for Virulence, Conidiation, DNA Damage Repair, and Multiple Stresses Resistance of .

Histone acetylation, which is critical for transcriptional regulation and various biological processes in eukaryotes, is a reversible dynamic process regulated by HATs and HDACs. This study determined the function of 6 histone acetyltransferases (HATs) (, , , , , ) and 6 histone deacetylases (HDACs) (, , , , , ) in the phytopathogenic fungus by analyzing targeted gene deletion mutants. Our data provide evidence that HATs and HDACs are both required for mycelium growth, cell development and pathogenicity as many gene deletion mutants (Δ, Δ, Δ, Δ, Δ, Δ, and Δ) displayed reduced growth, conidiation or virulence at varying degrees.

The chromosome-level genome provides insight into the molecular mechanism underlying the tortuous-branch phenotype of Prunus mume.

Plant with naturally twisted branches is referred to as a tortuous-branch plant, which have extremely high ornamental value due to their zigzag shape and the natural twisting of their branches. Prunus mume is an important woody ornamental plant. However, the molecular mechanism underlying this unique trait in Prunus genus is unknown.

Identification of the PmWEEP locus controlling weeping traits in Prunus mume through an integrated genome-wide association study and quantitative trait locus mapping.

Weeping Prunus mume (mei) has long been cultivated in East Asia for its specific ornamental value. However, little is known about the regulatory mechanism of the weeping trait in mei, which limits molecular breeding for the improvement of weeping-type cultivars. Here, we quantified the weeping trait in mei using nested phenotyping of 214 accessions and 342 F hybrids.

Genome-wide identification, characterisation, and evolution of subfamily in nine Rosaceae species and expression analysis in mei ().

Rosaceae is an important family containing some of the highly evolved fruit and ornamental plants. Abiotic stress responses play key roles in the seasonal growth and development of plants. However, the molecular basis of stress responses remains largely unknown in Rosaceae.

Comparative gene expression analysis reveals that multiple mechanisms regulate the weeping trait in Prunus mume.

Prunus mume (also known as Mei) is an important ornamental plant that is popular with Asians. The weeping trait in P. mume has attracted the attention of researchers for its high ornamental value.

A Computational Model for Inferring QTL Control Networks Underlying Developmental Covariation.

How one trait developmentally varies as a function of others shapes a spectrum of biological phenomena. Despite its importance to trait dissection, the understanding of whether and how genes mediate such developmental covariation is poorly understood. We integrate developmental allometry equations into the functional mapping framework to map specific QTLs that govern the correlated development of different traits.

Genome-wide identification, characterization and expression analysis of the HD-Zip gene family in the stem development of the woody plant .

The homeodomain-leucine zipper (HD-Zip) gene family, a group of plant-specific transcriptional factors (TFs), participates in regulating growth, development, and environmental responses. However, the characteristics and biological functions of HD-Zip genes in , which blooms in late winter or early spring, have not been reported. In this study, 32 HD-Zip genes, named - based on their chromosomal positions, were identified in the genome of .
