Generation of full-length cDNA clone and functional analysis of leader proteases of grapevine leafroll-associated virus-2

Creator:: Liu, Yu-Ping
Abstract:: Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...

Biology of chlamydospores of Phytophthora ramorum

Creator:: Smith, Aaron Lee
Abstract:: The chlamydospore is a survival spore produced by 35 of the 75 described species of Phytophthora. Phytophthora ramorum Werres, de Cock & Man in't Veld, the causal agent of Sudden Oak Death (SOD), produces abundant chlamydospores in artificial culture and plant tissue. The chlamydospore is likely the most important survival...

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

Nomenclature report on rice WRKY’s - Conflict regarding gene names and its solution

Creator:: Shen, Qingxi J., Yu, Diqiu, Jeon, Jong-Seong, Piffanelli, Pietro, Abbruscato, Pamela, Guo, Ze-Jian, Zhang, Yuanji, Itoh, Takeshi, Lee, Sung S., Buell, C. Robin, Nagato, Yasuo, McCouch, Susan, Yano, Masahiro, Wang, Guo-liang, Jena, Kshirod K., Xiong, Lizhong, Meyers, Blake, Jaiswal, Pankaj, and Yamazaki, Yukiko
Abstract:: Background: Since whole genome sequences of rice were made publically accessible, the number of articles on new rice genes has increased remarkably. The Committee on Gene Symbolization, Nomenclature and Linkage (CGSNL) of the Rice Genetics Cooperative published the gene nomenclature system for rice and encouraged researchers to follow the rules...

Small RNA binding is a common strategy to suppress RNA silencing by several viral suppressors

Creator:: Lakatos, Lóránt, Csorba, Tibor, Pantaleo, Vitantonio, Chapman, Elisabeth J., Carrington, James C., Liu, Yu-Ping, Dolja, Valerian V., Calvino, Lourdes Fernández, López-Moya, Juan José, and Burgyán, József
Abstract:: RNA silencing is an evolutionarily conserved system that functions as an antiviral mechanism in higher plants and insects. To counteract RNA silencing, viruses express silencing suppressors that interfere with both siRNA- and microRNA-guided silencing pathways. We used comparative in vitro and in vivo approaches to analyse the molecular mechanism of...

Genetic framework for flowering-time regulation by ambient temperature-responsive miRNAs in Arabidopsis

Creator:: Lee, Hanna, Yoo, Seong Jeon, Lee, Jeong Hwan, Kim, Wanhui, Yoo, Seung Kwan, Fitzgerald, Heather, Carrington, James C., and Ahn, Ji Hoon
Abstract:: Flowering is the primary trait affected by ambient temperature changes. Plant microRNAs (miRNAs) are small non-coding RNAs playing an important regulatory role in plant development. In this study, to elucidate the mechanism of flowering-time regulation by small RNAs, we identified six ambient temperature-responsive miRNAs (miR156, miR163, miR169, miR172, miR398 and...

The Pseudomonas aeruginosa antimetabolite L-2-amino-4-methoxy-trans-3-butenoic acid inhibits growth of Erwinia amylovora and acts as a seed germination-arrest factor

Creator:: Lee, Xiaoyun, Azevedo, Mark D., Armstrong, Donald J., Banowetz, Gary M., and Reimmann, Cornelia
Abstract:: The Pseudomonas aeruginosa antimetabolite L-2-amino-4-methoxy-trans-3-butenoic acid (AMB) shares biological activities with 4-formylaminooxyvinylglycine, a related molecule produced by Pseudomonas fluorescens WH6. We found that culture filtrates of a P.aeruginosa strain overproducing AMB weakly interfered with seed germination of the grassy weed Poa annua and strongly inhibited growth of Erwinia amylovora, the...

A recent disturbance history of forest ecosystems at Mount Rainier National Park

Creator:: Hemstrom, Miles A.
Abstract:: An analysis was made of the recent catastrophic disturbance history of forests at Mount Rainier National Park. Basic data were tree ages from ring counts of increment cores taken from the early seral cohort, field mapping of age class boundaries and aerial photograph interpretation. Maps of present stand ages were...

Origin and distribution of polyploid Achillea (Compositae) in western North America

Creator:: Tyrl, Ronald J.
Abstract:: A cytogeographical study was made of populations of tetraploid (n=18) and hexaploid (n=27) Achillea millefolium (Compositae- Anthemideae) from the Pacific Coast states. There is a complex distributional pattern, involving overlapping ranges, mixed populations, migration of one form into areas occuplied by the other, pentaploid hybrids, and septaploid and octoploid plants....
