Appearance quality of rice grains is a major problem for rice production in many areas of the world. We conducted a molecular marker-based genetic analysis of percentage of grains with chalkiness (PGWC), which is a determining factor for appearance quality; it strongly affects milling, eating and cooking quality. An F8 recombi.. Read More»

Wild olive (O. europaea ssp cuspidata) plants grow in various regions of Iran and are expected to have considerable genetic diversity due to adaptation to the various environmental conditions. We examined the genetic diversity of four populations of wild olive growing in Hormozgan Province located in southern Iran by using 30 .. Read More»

The successful development of hybrid cultivars depends on the reliability of estimated combining ability of the parent lines. The objectives of this study were to assess the combining ability of partially inbred S3 families of popcorn derived from the open-pollinated variety UENF 14, via top-crosses with four testers, and to c..

Trichomes are derived from the epidermis and constitute an ideal system for studying cell division in plants. Here, a Chinese cabbage doubled haploid (DH) line (FT) without trichomes was crossed with another DH line (PurDH-1) with trichomes to develop an F2 population for fine mapping of trichome control genes. Genetic analysi.. Read More»

Analyses conducted using repetitive DNAs have contributed to better understanding the chromosome structure and evolution of several species of insects. There are few data on the organization, localization, and evolutionary behavior of repetitive DNA in the family Lygaeidae, especially in Brazilian species. To elucidate the phy.. Read More»

Members of the 14-3-3 family of proteins are conserved regulatory proteins that are widely found in eukaryotes and play crucial roles in diverse physiological processes, including responses to different stresses. Although genome-wide analysis of 14-3-3 proteins has been performed in a few plant species, it has not been perform.. Read More»

The success of gene expression studies, protein synthesis, and construction of cDNA libraries directly depends on the purity and integrity of the RNA used in these tests, as even minor amounts of contaminant DNA (<1%) can produce a false positive amplification signal in quantitative real-time PCR. For RNA contaminated with .. Read More»

To elucidate the resistance of high-yield hybrid rice (Oryza sativa L.) at the seedling stage to low temperature, photosynthetic characteristics, such as membrane lipid peroxidation, fatty acid composition, and chloroplast ultrastructure, were investigated in a newly developed super-hybrid rice (‘Liangyoupeijiu’) a..

The aim of this study was to clone, express the gene of Hgp44 in adhesin domains of gingipains from Porphyromonas gingivalis and purify the protein. Furthermore, the effect of Hgp44 from P. gingivalis on inducing HUVECs to secrete IL-6 and IL-8 was evaluated. The Hgp44 gene fragment was amplified by polymerase chain reaction, .. Read More»
Authors: Molecular characterization and expression pattern of an �±-amylase gene (HcAmy) from the freshwater pearl mussel, Hyriopsis cumingii
The freshwater pearl mussel Hyriopsis cumingii is of commercial importance because it produces the freshwater pearl; however, knowledge about the molecular characterization and regulation mechanisms of α-amylase remains unknown for this species. In this study, the full-length cDNA of the α-amylase gene (.. Read More»
