Project description:Purpose: To study pre-meiotic (21-nt) and meiotic (24-nt) phasiRNA pathways in non-grass monocots Methods: Anthers were dissected using a 2 mm stage micrometer in a stereo microscope, and immediately frozen in liquid nitrogen until total RNA isolation was performed. Small RNA, mRNA libraries were generated using short-read (Illumina) and Single Molecule Real Time SMRT (PacBio) sequencing approaches. Stages were assigned based on the morphology of archesporial (AR) and tapetal cells of Lilium anthers.
Project description:The cDNA of 4 Lilium cultivars were sequenced in this study in order to develop SNP markers for mapping purpose. The four selected cultivars represent the four main hybrid groups in Lilium which are (Asiatic, Oriental, Longiflorum, and Trumpet). The SNP markers developed of this study will be implemented in mapping and association studies that aims to find SNP markers linked to virus resistance in Lilium. To achieve this target, SNP markers were generated from each cultivar separately, and of the four cultivars together trying to cover as much as variation in each cultivar and also to find SNP markers that can distinguish the four cultivars. Doing so, we hope to identify different genes resistance to virus in the four hybrid groups of Lilium.
