Heterotrichous ciliates play an important role in aquatic ecosystem energy flow processes and many are model organisms for research in cytology,regenerative biology,and *** the present study,we combine both morphological and molecular data to infer phylogenetic relationships at family-genus level and propose new evolutionary hypotheses for the class *** main results include:(1)96 new ribosomal DNA sequences from 36 populations,representing eight families and 13 genera,including three poorly annotated genera,Folliculinopsis,Ampullofolliculina and Linostomella;(2)the earliest-branching families are Spirostomidae in single-gene trees and Peritromidae in the concatenated tree,but the family Peritromidae probably represents the basal lineage based on its possession of many"primitive"morphological characters;(3)some findings in molecular trees are not supported by morphological evidence,such as the family Blepharismidae is one of the most recent branches and the relationship between Fabreidae and Folliculinidae is very close;(4)the systematic positions of Condylostomatidae,Climacostomidae,and Gruberiidae remain uncertain based either on morphological or molecular data;and(5)the monophyly of each genus included in the present study is supported by the molecular phylogenetic trees,except for Blepharisma in the SSU r DNA tree and Folliculina in the ITS1-5.8 S-ITS2 tree.

Morphogenesis and Molecular Phylogeny of a Marine Urostylid Ciliate Apokeronopsis wrighti(Protista, Ciliophora, Hypotrichia)

Hypotrichs are one of the highly differentiated ciliated lineages which play important roles in ecological, environmental,evolutionary and basic biological studies. In the present study, we investigated the living characteristics, infraciliature, nuclear apparatus, ontogenesis and phylogenetic position of a marine hypotrichous ciliate, Apokeronopsis wrighti Long et al., 2008, which was isolated from coastal waters in Shenzhen, China. The new isolate resembles the type population in terms of morphological characteristics, morphometrics, and SSU rRNA gene sequence that is with a 99.7% similarity. Ontogenesis of A. wrighti is characterized by oral primordium for the proter as well as marginal and dorsal kineties anlagen in both filial products formed de novo, and the cirral row arranged along the paroral and endoral arises from several anterior frontoventral-transverse cirral streaks. Phylogenetic analyses based on SSU and concatenated gene data suggest that five species of Apokeronopsis form a monophyletic clade, and the genus Apokeronopsis is closely related to Thigmokeronopsis and Metaurostylopsis.

A plant expression vector harboring four antifungal genes was delivered into the embryogenic calli of ‘9311’, an indica restorer line of Super Hybrid Rice, via modified biolistic particle bombardment. Southern blot analysis indicated that in the regenerated hygromycin-resistant plants, all the four anti-fungal genes, including RCH10, RAC22, β-Glu and B-RIP, were integrated into the genome of ‘9311’, co-transmitted altogether with the marker gene hpt in a Mendelian pattern. Some transgenic R1 and R2 progenies, with all transgenes displaying a normal expression level in the Northern blot analysis, showed high resistance to Magnaporthe grisea when tested in the typical blast nurseries located in Yanxi and Sanya respectively. Furthermore, transgenic F1 plants, resulting from a cross of R2 homo-zygous lines with high resistance to rice blast with the non-transgenic male sterile line Peiai 64S, showed not only high resistance to M. grisea but also enhanced resistance to rice false smut (a disease caused by Ustilaginoidea virens) and rice kernel smut (another disease caused by Tilletia barclayana).

The path toward prognostication and prediction in stage Ⅱ colon cancer

Engineering Sciences 2014年第4期12卷 51-58页

作者： Mohindra Nisha Division of Hematology/Oncology Department of Medicine Feinberg School of Medicine Northwestern University Chicago Illinois 60611 USA Robert H Lurie Comprehensive Cancer Center Northwestern University Chicago Illinois 60611 USA

Currently,there are several newer biomarkers that may be clinically useful in colon cancer. This paper focuses on a few of these biomarkers,namely microsatellite instability,loss of heterozygosity at chromosome 18q(LOH18q) and multi-gene assays,and discusses the clinical evidence behind their predictive or prognostic abilities. The results show that although there have been several newer prognostic factors identified,such as LOH18 q and multi-gene assays,none of these factors can predict benefit from treatment. Therefore,ongoing prospective clinical trials are still needed to further assess the role and optimal use of these tests.
