Feminization-1 homolog b (Fem1b) is one of the genes essential for male development and play central roles in sex determination of Caenorhabditis elegans. In this study, we cloned and characterized the full-length Fem1b cDNA from the freshwater prawn Macrobrachium nipponense (MnFem1b) in different tissues and at different developmental stages.
Testis-specific serine kinases (TSSKs) are a family of serine/threonine kinases highly expressed in the testes that are responsible for regulating many spermatogenesis-related protein activities. Mutations in this family have a positive relationship with oligospermia and azoospermia in human and mouse. Here, five members of the TSSK family from a Banna mini-pig inbred line (BMI) were cloned, sequenced, and characterized.
MicroRNAs (miRNAs) are a class of non-coding endogenous negative regulators that regulate gene expression at both the transcriptional and post-transcriptional levels. However, little is known about the expression characteristics of miRNAs during pollen development in Brassica oleracea. In this study, five known and three novel miRNAs were identified and their expression patterns were compared in the flower buds of B. oleracea using stem-loop reverse transcription polymerase chain reaction (RT-PCR) and quantitative real-time PCR.
Olfaction is crucial for insects’ survival because it enables them to recognize various environmental information. It is primarily mediated by a large family of chemoreceptors, including olfactory receptors (ORs), gustatory receptors (GRs), and ionotropic receptors (IRs). Here, we assembled the transcriptome of the economically important pest of palms, Rhynchophorus ferrugineus, to reveal its chemoreceptor gene repertoire. About 8.08 Gbp data were generated using a HiSeq platform and their assembly led to a total of 24,439 unigenes.
Fibroblast growth factor 5 (FGF5) is a secreted signaling protein that belongs to the FGF family, and was found to be associated with hair growth in humans and other animals. The Inner Mongolia Cashmere goat (Capra hircus) is a goat breed that provides superior cashmere; this breed was formed by spontaneous mutation in China. Here, we report the cloning, molecular characterization, and expression pattern of the Cashmere goat FGF5. The cloned FGF5 cDNA was 813 base pairs (KM596772), including an open reading frame encoding a 270-amino-acid polypeptide.
GRAS proteins are plant-specific transcription factors that are involved in the regulation of root and shoot growth. Here, we cloned BkGRAS2 from Betula kirghisorum (abbreviated to Bk) and analyzed the physicochemical properties and expression pattern of the encoded protein. BkGRAS2 had an open reading frame of 1614 bp encoding 537 amino acid residues. The deduced BkGRAS2 protein was hydrophilic, and it contained highly conserved VHIID and SAW motifs. BkGRAS1 and BkGRAS2 showed considerable sequence similarities.
CsICE1 is thought to be involved in hardiness resistance of tea plants. Using seedling cuttings of biennial Wuniuzao in this study, the pattern of CsICE1 expression under cold temperature (4°, -5°C), drought [20% polyethylene glycol 6000 (PEG-6000)], and plant hormone [200 mg/L abscisic acid (ABA), 1 mg/L brassinolide (BR)] treatment was studied by real-time quantitative PCR.
