Carassius auratus var. Pingxiangnensis; Expression analysis; Immunofluorescence; Real-time PCR; ZP3

Carassius auratus var. Pingxiangnensis (designated CaP), distributed in the Pingxiang region of Jiangxi Province, China, is a natural, wild triploid crucian carp mutant that has two reproductive development modes: gynogenesis and bisexual reproduction. Little information is available about the expression pattern of the zona pellucida 3 (ZP3) gene during ovarian ... more

Expression analysis; Gene cloning; Nelumbo nucifera; NnAP1

The objective of this study was to clone the full-length cDNA of the APETALA1 (AP1) gene from lotus and analyze its sequence and expression pattern. The full-length cDNA sequence of the NnAP1 gene was amplified from the petals of Nelumbo nucifera ‘Hongxia’ using RT-PCR and rapid amplification of cDNA ends. Bioinformatic methods were used to analyze the ... more

Expression analysis; Hyriopsis cumingii; In situ hybridization; Laminin receptor precursor; Shell repair

Hyriopsis cumingii is an economically important freshwater pearl mussel with high pearl quality that is endemic in China. Investigation of genes relevant to shell formation is important for increased pearl output. The substances that form mollusk shells are secreted by epithelial cells in the mantle, the proliferation of which influences secretion ability. This study focused on ... more

CCoAOMT1 cloning; Chlorogenic acid synthetase; Expression analysis; Lonicera japonica Thunb.

Complete coding DNA sequences of a closely related chlorogenic acid synthetase gene (LjCCoAOMT1) were isolated from Lonicera japonica Thunb. by reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE). LjCCoAOMT1 was subsequently overexpressed in Escherichia coli and a 25-kD protein was detected by ... more

DapcaDsx2 gene; Daphnia carinata; Expression analysis; Reproductive transformation; Whole-mount in situ hybridization

To better understand the reproductive transformation mechanism of Daphnia carinata, a Doublesex (Dsx) gene was cloned based on rapid amplification of cDNA ends (RACE), and was designated DapcaDsx2. Next, we compared similarities and assumed homology based on deduced amino acid sequences. It showed 97.52, 87.94, and 85.11% identity to orthologous genes ... more

Capsicum annuum L.; CaRCCR gene; Cloning; Expression analysis; Stress response

Opening the porphyrin macrocycle of pheophorbide a and forming the primary fluorescent chlorophyll catabolites are key steps in the chlorophyll catabolism pathway. These steps are catalyzed by pheophorbide a oxygenase and red chlorophyll catabolite reductase (RCCR). In this study, a novel RCCR gene, CaRCCR, was isolated from the pepper (Capsicum annuum ... more

Anthocephalus chinensis; Gene cloning; Phylogenetic tree; α-expansin

Expansins are cell wall-associated proteins that induce wall extension and relax stress by disrupting noncovalent bonds between cellulose microfibrils and cross-linking glycan chains, thereby promoting wall creep. Anthocephalus chinensis is a very fast-growing economically important tree found mainly in South Asia. Sixteen cDNAs, designated AcEXPA1 to AcEXPA16 ( ... more

FastJoin; Neighbor-joining algorithm; Phylogenetic analysis; Phylogenetic tree

Reconstructing the evolutionary history of a set of species is an elementary problem in biology, and methods for solving this problem are evaluated based on two characteristics: accuracy and efficiency. Neighbor-joining reconstructs phylogenetic trees by iteratively picking a pair of nodes to merge as a new node until only one node remains; due to its good accuracy and speed, it has been ... more

Database; Foxtail millet; Gene clusters; Nucleotide-binding site; Phylogenetic tree

The nucleotide-binding site (NBS) disease-resistance genes are the largest category of plant disease-resistance gene analogs. The complete set of disease-resistant candidate genes, which encode the NBS sequence, was filtered in the genomes of two varieties of foxtail millet (Yugu1 and ‘Zhang gu’). This study investigated a number of characteristics of the putative NBS genes, such as ... more

Pentatricopeptide repeat protein family; Phylogenetic tree; Quantitative reverse transcription polymerase chain reaction; Rf gene; Sequence structure analysis

As a model plant, mechanisms of the cytoplasmic male sterility/restoration of fertility (CMS/Rf) system in tobacco are seldom studied. Using Rf gene sequences from other Solanaceae plants and the draft genome of Nicotiana benthamiana, degenerate primers were designed to amplify the cDNA pool of N. tomentosiformis. In total, six possible Rf ... more
