Abstract Cellular RNAs are heterogeneous with respect to their alternative processing and secondary structures, but the functional importance of this complexity is still poorly understood. A set alternatively processed antisense non-coding transcripts, which collectively called COOLAIR , generated at Arabidopsis floral-repressor locus FLOWERING LOCUS C ( FLC ) 1 . Different isoforms influence transcriptional output in warm cold conditions 2–7 Here, further investigate function we developed...
Plants integrate widely fluctuating temperatures to monitor seasonal progression. Here, we investigate the temperature signals in field conditions that result vernalisation, mechanism by which flowering is aligned with spring. We find multiple, distinct aspects of profile contribute vernalisation. In autumn, transient cold promote transcriptional shutdown Arabidopsis FLOWERING LOCUS C (FLC), independently factors conferring epigenetic memory. As winter continues, expression VERNALIZATION...
Plants monitor many aspects of their fluctuating environments to help align development with seasons. Molecular understanding how noisy temperature cues are registered has emerged from dissection vernalization in Arabidopsis, which involves a multiphase cold-dependent silencing the floral repressor locus FLOWERING LOCUS C (FLC). Cold-induced transcriptional precedes low probability PRC2 epigenetic switching mechanism. The switch requires absence warm temperatures as well long-term cold...
Abstract The ultimate understanding of how biological diversity arises, is maintained, and lost depends on identifying the genes responsible. Although a good deal has been discovered about gene function over past few decades, far less understood effects, that is, natural variation in contributes to phenotypes. Trichome density Arabidopsis thaliana an ideal trait for studies molecular phenotypic variation, as trichome initiation genetically well‐characterized highly variable among...
Significance Epigenetic regulation of gene expression is associated with switching between chromatin states characterized by distinct histone modifications. Polycomb/Trithorax involves the mutually exclusive H3K27me3/H3K36me3 modifications, but how these are faithfully inherited through DNA replication, yet can switch from one to another, still poorly understood. One mechanism that would aid association methyltransferases factors demethylating opposing modification. Here, we show an...
Tuber bruising in tetraploid potatoes (Solanum tuberosum) is a trait of economic importance, as it affects tubers' fitness for sale. Understanding the genetic components affecting tuber key step developing potato lines with increased resistance to bruising. As setting renders analyses more complex, there still much learn about this complex phenotype. Here, we used capture sequencing data on panel half-sibling populations from breeding programme perform genome-wide association analysis (GWAS)...
Herbivory imposes an important selective pressure on plants. In Arabidopsis thaliana leaf trichomes provide a key defense against insect herbivory; however, trichome production incurs fitness cost in the absence of herbivory. Previous work A. has shown increase density response to damage, suggesting mechanism by which associated with constitutively high might be mitigated; genetic basis induction not been studied. Here, we describe mapping quantitative trait loci (QTL) for constitutive and...
