Revisiting the type species of the genus (Collembola, Entomobryidae).

Börner, 1906, the type species of the genus Börner, 1906, is widespread from India to Southeast Asia, but its detailed morphological characteristics have not yet been described. We examined the morphology of specimens of from Indonesia and southwestern China and confirmed their conspecific status by comparing their DNA barcoding sequences. We also compared the morphology of with other two closely related species, confirming the valid species status of Denis, 1948.

A comprehensive checklist of the deciduous photinia genus (Maleae, Rosaceae), with emphasis on their validity and typification.

Due to the complicated evolutionary history in , ninety-seven taxa have been described since 1784, and ninety-one of them are validly published taxa, five are naked names, and one is an invalid name. After a comprehensive and critical evaluation, 213 names have been published, including new combinations, new status, and new names; this may be due to the controversial taxonomic position of in the apple tribe, Maleae. We herewith provide a taxonomic checklist of for further taxonomic and evolutionary studies.

A new species of Börner (Collembola, Symphypleona, Arrhopalitidae) from China, with a key to the Asian species of the group.

The second species of from China is described and illustrated and an identification key to the Asian species of the group is presented. is the eleventh species of the group recorded in Asia and it can be clearly differentiated by the unguiculus III with 2 internal teeth (0-1 in all other species). Also, the combination of antennae less than 2 times the size of the head, antennal segment IV without annulations, 1+1 eyes, dorsal head with 9 spines, 2+2 regular spines per side on the anal valves, circumanal chaetae without basal serrations, subanal appendage long and apically serrated, manubrium with 5+5, and dorsal dens with 16 chaetae is unique among the Asian species of the group.

New species of the genus Curtis, 1834 (Trichoptera, Molannidae) in China inferred from morphology and DNA barcodes.

The male adult of Ge, Peng & Sun is described and illustrated based on material collected in Si-chuan, China. It could be diagnosed by the subtriangular superior appendages when viewed dorsally, and by the mesal appendages each having a slender thorn and inferior appendages with a tiny inner process. Based on morphology of genitalia, we provide a dichotomous key to adult males of from the Oriental region.

Mitochondrial Genomes of Two Asexual (Hymenoptera: Trichogrammatidae) Strains and Comparison with Their Sexual Relatives.

Despite its substantial costs, sexual reproduction dominates in animals. One popular explanation for the paradox of sex is that asexual reproduction is more likely to accumulate deleterious mutations than sexual reproduction. To test this hypothesis, we compared the mitogenomes of two asexual wasp strains, and to their sexual relatives.

A new species of Westwood (Hymenoptera, Encyrtidae) as a hyperparasitoid of the invasive cotton mealybug, Tinsley, in China.

A new species, , from Eastern China is described. It is similar to Hayat but distinct from it in a number of morphological characters. It is a hyperparasitoid with the encyrtid wasp Girault, 1915 as the primary host and the cotton mealybug Tinsley, 1898 (Hemiptera: Pseudococcidae) as the secondary host.

Estrogen receptor alpha regulates the Wnt/β-catenin signaling pathway in colon cancer by targeting the NOD-like receptors.

It has been reported that estrogen receptors (ERs) participate in carcinogenesis by directly regulating NOD-like receptors (NLRs). However, the expression profiles of ERs and NLRs in tumor and the ER-NLR regulated signaling pathway are not clear. In this study, we summarized gene expression profiles of ERs and NLRs across normal and tumor tissue by comprehensive data mining.

Identification of massive molecular markers in using a restriction-site associated DNA approach.

proliferation seriously threatens rice production worldwide. We combined a restriction-site associated DNA (RAD) approach with Illumina DNA sequencing for rapid and mass discovery of simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers for . RAD tags were generated from the genomic DNA of two plants, and sequenced to produce 5197.

Fenoxaprop-P-ethyl resistance conferred by cytochrome P450s and target site mutation in Alopecurus japonicus.

Background: Alopecurus japonicus is a serious grass weed species in wheat fields in eastern Asia, and has evolved strong resistance to acetyl-CoA carboxylase (ACCase)-inhibiting herbicides. Although target-site resistance (TSR) to ACCase inhibitors in A. japonicus has been reported, non-target site resistance (NTSR) has not.

Mechanism of resistance to cyhalofop-butyl in Chinese sprangletop (Leptochloa chinensis (L.) Nees).

Chinese sprangletop (Leptochloa chinensis (L.) Nees) is a serious grass weed in rice paddies. In some areas, L.

Molecular basis of ALS- and/or ACCase-inhibitor resistance in shortawn foxtail (Alopecurus aequalis Sobol.).

Alopecurus aequalis, a predominant weed species in wheat and oilseed rape fields, can no longer be controlled by mesosulfuron-methyl application after continuous use over several years. Based on dose-response studies, the putative resistant populations, JTJY-1 and JHHZ-1, were found to be resistant to mesosulfuron-methyl, with resistance index values of 5.5 and 14, respectively.

Determination of ploidy level and isolation of genes encoding acetyl-CoA carboxylase in Japanese Foxtail (Alopecurus japonicus).

Ploidy level is important in biodiversity studies and in developing strategies for isolating important plant genes. Many herbicide-resistant weed species are polyploids, but our understanding of these polyploid weeds is limited. Japanese foxtail, a noxious agricultural grass weed, has evolved herbicide resistance.

Mechanism of resistance to fenoxaprop in Japanese foxtail (Alopecurus japonicus) from China.

Japanese foxtail is one of the most common and troublesome weeds infesting cereal and oilseed rape fields in China. Repeated use during the last three decades of the ACCase-inhibiting herbicide fenoxaprop-P-ethyl to control this weed has resulted in the occurrence of resistance. Dose-response tests established that a population (AHFD-1) from eastern China had evolved high-level resistance to fenoxaprop-P-ethyl.

Mutations at codon position 1999 of acetyl-CoA carboxylase confer resistance to ACCase-inhibiting herbicides in Japanese foxtail (Alopecurus japonicus).

Background: The intensive and global application of ACCase-inhibiting herbicides has resulted in the evolution of resistance in a growing number of grass weeds. Among the mutations implicated in conferring resistance, limited knowledge is available regarding mutations at codon position 1999. In addition, multiple copies of genes encoding plastidic ACCase have been ignored in previous studies of resistance in Alopecurus japonicus.
