Project description:Ten-month-old male beagle canines were purchased from the ANNIMO Science and Technology Ltd (Nanjing, China, Certificate No. SCXK (Su) 2010-0002), and maintained in a specific pathogen-free environment. Canines were randomly assigned to two groups (4 in each group) and received capsules with control filler or Aristolochic Acid I (AAI) filler (3 mg/kg/day, equivalent dose of mouse) for 10 days. Canines were sacrificed at 11 days after initiation of the treatment. Livers were excised immediately after sacrifice. Part of the livers were immediately snap-frozen in liquid nitrogen and kept at -80°C for total RNA isolation and microRNA microarray analysis.
Project description:Pistachio (Pistacia vera) is a drought and salinity-tolerant perennial whose fruit features a fleshy exo-mesocarp, or “hull,” that protects the kernel. Hull development and degradation are key to kernel quality, yet the anatomy and mechanisms driving hull breakdown during late-stage development remain largely unknown. Here, we show that the hull contains anatomically distinct layers of hypodermal parenchyma and filler parenchyma. Using a combination of transcriptome analyses and immunohistochemistry, we show that changes in pectin associated gene expression and modification of this polysaccharide are involved in hull cell size increase, loss of cell-cell adhesion, and softening. Anatomical analysis shows that filler parenchyma expands during late-stage hull development while hypodermal parenchyma remains constant in size. Field data suggest that irrigation and humidity affect pistachio hull split, implicating a role for water status in cell expansion. In summary, the complex interplay between molecular, cellular, and environmental changes suggests that cell layer–specific modifications of the cell wall are linked to exo-mesocarp splitting, forming a model for understanding the mechanism of fruit split during ripening in non-berry fruit crops.
Project description:Metagenome data from soil samples were collected at 0 to 10cm deep from 2 avocado orchards in Channybearup, Western Australia, in 2024. Amplicon sequence variant (ASV) tables were constructed based on the DADA2 pipeline with default parameters.
Project description:DNA, RNA and protein were extracted from the culture and subjected to massive parallel sequencing and nano-LC-MS-MS respectively Combination of these methods enabled the reconstruction of the complete genome sequence of M oxyfera from the metagenome and identification of the functionally relevant enzymes and genes
