BACKGROUND C2H2 zinc-finger (C2H2-ZF) proteins are a large gene family in plants that participate in various aspects of normal plant growth and development, as well as in biotic and abiotic stress responses. To date, no overall analysis incorporating evolutionary history and expression profiling of the C2H2-ZF gene family in model tree species poplar(More)
Because of frequent exposure to carcinogens, the bronchus is prone to early pathologic alterations. The assessment of these early changes is of key significance in physiological studies and disease diagnosis of the bronchus. We utilize nonlinear optical microscopy (NLOM) to image mouse bronchial tissue based on intrinsic nonlinear optical contrast. Our(More)
C3HC4-type RING finger genes belong to a large gene family in plants and play crucial roles in diverse stress responses. In this study, a comprehensive analysis of the poplar (Populus trichocarpa) C3HC4-type RING finger gene family was performed, including analysis of phylogenetic relationships, chromosomal locations, gene structures, motif compositions,(More)
Trihelix genes play important roles in plant growth and development and responses to biotic and abiotic stresses. Here, we identified 56 full-length trihelix genes in Populus trichocarpa and classified them into five groups. Most genes within a given group had similar gene structures and conserved motifs. The trihelix genes were unequally distributed across(More)
Copper transporters (COPT/Ctr) have important roles in the transport of copper (Cu) across the cell membrane in many different species. A comprehensive phylogeny and a molecular structure analysis of the COPT/Ctr family in plants and animals are presented, with an emphasis and bioinformatic analysis of the copper transporter family in Populus trichocarpa(More)
The heavy metal ATPase (HMA) family plays an important role in transition metal transport in plants. However, this gene family has not been extensively studied in Populus trichocarpa. We identified 17 HMA genes in P. trichocarpa (PtHMAs), of which PtHMA1-PtHMA4 belonged to the zinc (Zn)/cobalt (Co)/cadmium (Cd)/lead (Pb) subgroup, and PtHMA5-PtHMA8 were(More)
This paper for the first time provides insights into the important roles of the miRNAs during blooming period in Populus simonii × P. nigra. MicroRNAs (miRNAs) are small RNAs that act as regulators of eukaryotic gene expression at the post-transcriptional level. Using high-throughput sequencing technology, we analyzed miRNAs in Populus. simonii × P. nigra(More)
