Project description:Iso-Seq (PacBio) sequencing was performed to generate a reference library of H. perforatum. We generated genome-wide transcriptome data from in vitro cell suspensions and shoot cultures of H. perforatum.
Project description:The aim of this experiment was to obtain full length transcript sequences of genes expressed in leaves and stems of narrow-leafed lupin (Lupinus angustifolius L.) using PacBio Iso-Seq. Total RNA was isolated from leaves and stems of five narrow-leafed lupin (Lupinus angustifolius L.) genotypes with contrasting alkaloid regulation, including an iucundus low-alkaloid line (83A:476), a bitter Iucundus line (P27255) and three Bryansk low-alkaloid lines carrying the Iucundus-type RAP2-7 allele: 95826 (Bryanskij-35), 95927 (Bryanskij-123) and 95928 (Bryanskij-237/83). Plants, in five replicates per genotype, were grown under controlled conditions optimal for growth, and leaf and stem samples were collected at flowering stage. For each genotype and organ, total RNA from five biological replicates was pooled in equal amounts and used for PacBio Iso-Seq library preparation and sequencing.
Project description:Full-Length cDNA transcriptome (Iso-Seq) data sequenced on the PacBio Sequel system using 2.1 chemistry. Multiplexed cDNA library of 12 samples (3 tissues x 4 strains). Tissues: root, embryo, endosperm. Strains: B73, Ki11, B73xKi11, Ki11xB73.
Project description:The timing of flower opening is essential for pollination and thus seed production. Despite flower opening has been a long lasting topic for plant biologists, the underling molecular mechansim remains elusive. Here we used a unique cucumber line ‘6457’ that spontaneously produces super ovary with delayed corolla opening as material, and explored the physiological, cytological, nutritional and transcriptomic reasons for the delayed corolla opening in super ovary. Our data showed that cell division and cell expansion persisited for a longer period of time in the super ovary, especially during the green yellow bud stage and yellow bud stage. Similarly, RNA-seq analyses showed that RNA and protein synthesis related genes were upregulated during these two stages, which may account for the decreased nitrogen and phosphrate content in the super ovary. Further, activation of transcription factors were delayed in the green yellow bud stage, while signalling kinases related genes were upregulated in the yellow bud stage in the super ovary. Photosynthesis related genes were also significantly activated in the super ovary, which corresponds to the increased soluble suble content. Phytohoromones such as cytokinins and gibberllins were elevated in the super ovary. Consistently, cytokinins and gibberllins related genes showed significantly enhanced expression. Therefore, both developmental and nutritional factors regulate the timing of female flower opening in cucumber, and provide a valuable foundation for dissecting the underling regulatory pathways of flower opening in planta.
