Open AccessHarbinger transposon insertion in ethylene signaling gene leads to emergence of new sexual forms in cucurbits
In flowering plants, the predominant sexual morph is hermaphroditism, and the emergence of unisexuality is poorly understood. Using Cucumis melo (melon) as a model system, we explore the mechanisms driving sexual...

Open AccessThe Arabidopsis APOLO and human UPAT sequence-unrelated long noncoding RNAs can modulate DNA and histone methylation machineries in plants
RNA-DNA hybrid (R-loop)-associated long noncoding RNAs (lncRNAs), including the Arabidopsis lncRNA AUXIN-REGULATED PROMOTER LOOP (APOLO), are emerging as important regulators of three-dimensional chromatin confor...

Open AccessGenetic and environmental modulation of transposition shapes the evolutionary potential of Arabidopsis thaliana
How species can adapt to abrupt environmental changes, particularly in the absence of standing genetic variation, is poorly understood and a pressing question in the face of ongoing climate change. Here we lev...

Detection of Transposable Element Insertions in Arabidopsis Using Sequence Capture
Transposable elements (TEs) are repetitive DNA sequences that have the ability to mobilize in the genome and create major effect mutations. Despite the importance of transposition as a source of genetic novelt...

Protocol
Efficient Detection of Transposable Element Insertion Polymorphisms Between Genomes Using Short-Read Sequencing Data
Transposable elements (TEs) are powerful generators of major-effect mutations, most of which are deleterious at the species level and maintained at very low frequencies within populations. As reference genomes...

Open AccessThe impact of transposable elements on tomato diversity
Tomatoes come in a multitude of shapes and flavors despite a narrow genetic pool. Here, we leverage whole-genome resequencing data available for 602 cultivated and wild accessions to determine the contribution...

Open AccessRelaxed purifying selection in autopolyploids drives transposable element over-accumulation which provides variants for local adaptation
Polyploidization is frequently associated with increased transposable element (TE) content. However, what drives TE dynamics following whole genome duplication (WGD) and the evolutionary implications remain un...

Article
Open AccessTransposition favors the generation of large effect mutations that may facilitate rapid adaption
Transposable elements (TEs) are mobile parasitic sequences that have been repeatedly coopted during evolution to generate new functions and rewire gene regulatory networks. Yet, the contribution of active TEs ...

Article
Open AccessDifferential retention of transposable element-derived sequences in outcrossing Arabidopsis genomes
Transposable elements (TEs) are genomic parasites with major impacts on host genome architecture and host adaptation. A proper evaluation of their evolutionary significance has been hampered by the paucity of ...

Article
Open AccessTE-Tracker: systematic identification of transposition events through whole-genome resequencing
Transposable elements (TEs) are DNA sequences that are able to move from their location in the genome by cutting or copying themselves to another locus. As such, they are increasingly recognized as impacting a...

Natural occurring epialleles determine vitamin E accumulation in tomato fruits
Vitamin E (VTE) content is a low heritability nutritional trait for which the genetic determinants are poorly understood. Here, we focus on a previously detected major tomato VTE quantitative trait loci (QTL; ...

Article
Transcriptional regulation of tocopherol biosynthesis in tomato
Tocopherols, compounds with vitamin E (VTE) activity, are potent lipid-soluble antioxidants synthesized only by photosynthetic organisms. Their biosynthesis requires the condensation of phytyl-diphosphate and ...

Concerted regulation of nuclear and cytoplasmic activities of SR proteins by AKT
Serine/arginine-rich (SR) proteins are important regulators of mRNA splicing. Several postsplicing activities have been described for a subset of shuttling SR proteins, including regulation of mRNA export and ...
