TL;DR: Analysis of molecular divergence compared with yeasts and metazoans reveals rapid rates of gene diversification in diatoms, and documents the presence of hundreds of genes from bacteria, likely to provide novel possibilities for metabolite management and for perception of environmental signals.
Journal ArticleDOI
The Arabidopsis SLEEPY1 Gene Encodes a Putative F-Box Subunit of an SCF E3 Ubiquitin Ligase
Karen M. McGinnis,Stephen G. Thomas,Jonathan D. Soule,Lucia C. Strader,Janice M. Zale,Tai-ping Sun,Camille M. Steber +6 more
TL;DR: The predicted SLY1 amino acid sequence is highly conserved among plants, indicating a key role in GA response, and suggests SCFSLY1-targeted degradation of RGA through the 26S proteasome pathway.
Journal ArticleDOI
An RNA-dependent RNA polymerase is required for paramutation in maize

TL;DR: It is proposed that the mop1 RDRP is required to maintain a threshold level of repeat RNA, which functions in trans to establish and maintain the heritable chromatin states associated with paramutation.
Journal ArticleDOI
Genome-wide analyses of alternative splicing in plants : Opportunities and challenges
TL;DR: Evidence suggests that AS participates in important plant functions, including stress response, and may impact domestication and trait selection, as well as determine the influence of genome duplication on the evolution of AS.
Journal ArticleDOI
RNA-directed DNA methylation enforces boundaries between heterochromatin and euchromatin in the maize genome
Qing Li,Jonathan I. Gent,Gregory J Zynda,Jawon Song,Irina Makarevitch,Cory D. Hirsch,Candice N. Hirsch,R. Kelly Dawe,Thelma F. Madzima,Karen M. McGinnis,Damon Lisch,Robert J. Schmitz,Matthew W. Vaughn,Nathan M. Springer +13 more
TL;DR: It is found that the regions of elevated CHH methylation, termed mCHH islands, are the boundaries between highly methylated (CG, CHG, silenced chromatin and more active chromatin), and the analysis of DNA methylation in other sequence contexts and several chromatin modifications revealed that mCHh islands mark the transition from heterochromatin-associated modifications to euchromatin -associated modifications.
