Article Abstract
The dinoflagellate Scrippsiella acuminata (formerly Scrippsiella trochoidea) is a cosmopolitan species commonly forms dense blooms worldwide. It also has been adopted as representative species for life history studies on dinoflagellates. The peculiar genetic features of its large nuclear genome make the whole-genome sequencing highly challenging. Herein, we employed single-molecule real-time (SMRT) sequencing technology to acquire the full-length transcriptome of S. acuminata at different life stages (vegetative cells at different growth stages and resting cysts). A total of 51.44 Gb clean SMRT sequencing reads were generated, which finally yielded 226,117 non-redundant full-length non-chimeric (FLNC) reads. Among them, 78,393 long non-coding RNA (lncRNA), 550 putative transcription factors (TF) members from 19 TF families, 67,212 simple sequence repeats (SSRs), and 116,417 protein coding sequences (CDSs) were identified. This is the first report on full-length transcriptome of Thoracosphaeraceae in Dinophyceae, which is valuable for future genome annotation in this order. Our dataset provides a reference transcriptomic background for life history studies on dinoflagellates and will contribute to understanding molecular mechanisms underlying S. acuminata blooms.

Bulbil formation in Lilium lancifolium represents a pivotal vegetative reproduction strategy, yet the transcriptional regulatory network governing this process remains largely uncharacterized. Here, we identify LlLRP1 by full-length cloning, sequence analysis and subcellular localization, an SHI/SRS family transcription factor, as a key mediator of bulbil morphogenesis. Transcriptomic profiling revealed that LlLRP1 is a downstream target of LlWOX11, with its promoter harboring conserved binding motifs (AAAG, AGTA) validated by yeast one-hybrid, dual-luciferase reporter, and electrophoretic mobility shift assays.

Motivation: Recent advancements in long-read single-cell RNA sequencing (scRNA-seq) have facilitated the quantification of full-length transcripts and isoforms at the single-cell level. Historically, long-read data would need to be complemented with short-read single-cell data in order to overcome the higher sequencing errors to correctly identify cellular barcodes and unique molecular identifiers. Improvements in Oxford Nanopore sequencing, and development of novel computational methods have removed this requirement.

Polyadenylation is a dynamic process that is important in cellular physiology, which has implications in messenger RNA decay rates, translation efficiency, and isoform-specific regulation. Oxford Nanopore Technologies direct RNA sequencing provides a strategy for sequencing the full-length RNA molecule and analysis of the transcriptome. Several tools are currently available for poly(A) tail length estimation, including well-established methods like tailfindr and nanopolish, as well as more recent deep learning models like Dorado.

Anthocyanins are pigments that confer color in plants. Although extensive research has been conducted on anthocyanin biosynthesis, the molecularly modulated mechanisms responsible for flower gradient coloration remain largely unknown. Lycoris albiflora 'Astro Girl' flowers gradually turn from white to pink after flowering, making them suitable for studying the regulatory mechanisms of anthocyanin accumulation.
