A Phytophthora sojae Glycoside Hydrolase 12 Protein Is a Major Virulence Factor during Soybean Infection and Is Recognized as a PAMP

Creator:: Ma, Zhenchuan, Song, Tianqiao, Zhu, Lin, Ye, Wenwu, Wang, Yang, Shao, Yuanyuan, Dong, Suomeng, Zhang, Zhengguang, Dou, Daolong, Zheng, Xiaobo, Tyler, Brett M., and Wang, Yuanchao
Abstract:: We identified a glycoside hydrolase family 12 (GH12) protein, XEG1, produced by the soybean pathogen Phytophthora sojae that exhibits xyloglucanase and β-glucanase activity. It acts as an important virulence factor during P. sojae infection but also acts as a pathogen-associated molecular pattern (PAMP) in soybean (Glycine max) and solanaceous species,...

Paired-End Analysis of Transcription Start Sites in Arabidopsis Reveals Plant-Specific Promoter Signatures

Creator:: Morton, Taj, Petricka, Jalean, Corcoran, David L., Li, Song, Winter, Cara M., Carda, Alexa, Benfey, Philip N., Ohler, Uwe, and Megraw, Molly
Abstract:: Understanding plant gene promoter architecture has long been a challenge due to the lack of relevant large-scale data sets and analysis methods. Here we present a publicly available, large-scale transcription start site (TSS) dataset in plants using a high-resolution method for analysis of 5’ ends of mRNA transcripts. Our dataset...

Whole-Plant Growth Stage Ontology for Angiosperms and Its Application in Plant Biology

Creator:: Pujar, Anuradha, Jaiswal, Pankaj, Kellogg, Elizabeth A., Ilic, Katica, Vincent, Leszek, Avraham, Shulamit, Stevens, Peter, Zapata, Felipe, Reiser, Leonore, Rhee, Seung Y., Sachs, Martin M., Schaeffer, Mary, Stein, Lincoln, Ware, Doreen, and McCouch, Susan
Abstract:: Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth...

Taking the Next Step: Building an Arabidopsis Information Portal

Creator:: International Arabidopsis Informatics Consortium, Bastow, Ruth, Beynon, Jim, Brendel, Volker, Dooley, Rion, Friesner, Joanna, Grotewold, Erich, Huala, Eva, Loraine, Ann, Meyers, Blake, Pires, J. Chris, Provart, Nicholas, Stanzione, Dan, Town, Chris, and Ware, Doreen
Abstract:: The Arabidopsis Information Portal (AIP), a resource expected to provide access to all community data and combine outputs into a single user-friendly interface, has emerged from community discussions over the last 23 months. These discussions began during two closely linked workshops in early 2010 that established the International Arabidopsis Informatics...

The Plant Structure Ontology, a Unified Vocabulary of Anatomy and Morphology of a Flowering Plant

Creator:: Ilic, Katica, Kellogg, Elizabeth A., Jaiswal, Pankaj, Zapata, Felipe, Stevens, Peter F., Vincent, Leszek P., Avraham, Shulamit, Reiser, Leonore, Pujar, Anuradha, Sachs, Martin M., Whitman, Noah T., McCouch, Susan R., Schaeffer, Mary L., Ware, Doreen H., Stein, Lincoln D., and Rhee, Seung Y.
Abstract:: Formal description of plant phenotypes and standardized annotation of gene expression and protein localization data require uniform terminology that accurately describes plant anatomy and morphology. This facilitates cross species comparative studies and quantitative comparison of phenotypes and expression patterns. A major drawback is variable terminology that is used to describe...

Expression, Splicing, and Evolution of the Myosin Gene Family in Plants

Creator:: Peremyslov, Valera V., Mockler, Todd C., Filichkin, Sergei A., Fox, Samuel E., Jaiswal, Pankaj, Makarova, Kira S., Koonin, Eugene V., and Dolja, Valerian V.
Abstract:: Plants possess two myosin classes, VIII and XI. The myosins XI are implicated in organelle transport, filamentous actin organization, and cell and plant growth. Due to the large size of myosin gene families, knowledge of these molecular motors remains patchy. Using deep transcriptome sequencing and bioinformatics, we systematically investigated myosin...

Identification of Myosin XI Receptors in Arabidopsis Defines a Distinct Class of Transport Vesicles

Creator:: Peremyslov, Valera V., Morgun, Eva A., Kurth, Elizabeth G., Makarova, Kira S., Koonin, Eugene V., and Dolja, Valerian V.
Abstract:: To characterize the mechanism through which myosin XI-K attaches to its principal endomembrane cargo, a yeast two-hybrid library of Arabidopsis thaliana cDNAs was screened using the myosin cargo binding domain as bait. This screen identified two previously uncharacterized transmembrane proteins (hereinafter myosin binding proteins or MyoB1/2) that share a myosin...

Functional Analysis of Three Arabidopsis ARGONAUTES Using Slicer-Defective Mutants

Creator:: Carbonell, Alberto, Fahlgren, Noah, Garcia-Ruiz, Hernan, Gilbert, Kerrigan B., Montgomery, Taiowa A., Nguyen, Tammy, Cuperus, Josh T., and Carrington, James C.
Abstract:: In RNA-directed silencing pathways, ternary complexes result from small RNA-guided ARGONAUTE (AGO) associating with target transcripts. Target transcripts are often silenced through direct cleavage (slicing), destabilization through slicer-independent turnover mechanisms, and translational repression. Here, wild-type and active-site defective forms of several Arabidopsis thaliana AGO proteins involved in posttranscriptional silencing were...

Green Revolution Trees: Semidwarfism Transgenes Modify Gibberellins, Promote Root Growth, Enhance Morphological Diversity, and Reduce Competitiveness in Hybrid Poplar

Creator:: Elias, Ani A., Busov, Victor B., Kosola, Kevin R., Ma, Cathleen, Etherington, Elizabeth, Shevchenko, Olga, Gandhi, Harish, Pearce, David W., Rood, Stewart B., and Strauss, Steven H.
Abstract:: Semidwarfism has been used extensively in row crops and horticulture to promote yield, reduce lodging, and improve harvest index, and it might have similar benefits for trees for short-rotation forestry or energy plantations, reclamation, phytoremediation, or other applications. We studied the effects of the dominant semidwarfism transgenes GA Insensitive (GAI)...

Antisense down-regulation of 4CL expression alters lignification, tree growth and saccharification potential of field-grown poplar

Creator:: Voelker, Steven L., Lachenbruch, Barbara, Meinzer, Frederick C., Jourdes, Michael, Ki, Chanyoung, Patten, Ann M., Davin, Laurence B., Lewis, Norman G., Tuskan, Gerald A., Gunter, Lee, Decker, Stephen R., Selig, Michael J., Sykes, Robert, Himmel, Michael E., Kitin, Peter, Shevchenko, Olga, and Strauss, Steven H.
Abstract:: Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate:coenzyme A ligase (4CL) has been reported as a means for reducing lignin content in cell walls and increasing overall growth rates, thereby improving feedstock quality for paper and bioethanol production. Using hybrid poplar (Populus tremula 3 Populus alba), we applied this...
