Plants are built of various specialized cell types that differ in their wall composition and structure. The walls certain tissues (xylem, sclerenchyma) characterized by the presence heterogenous polymer lignin plays an essential role physiology. This phenolic is composed different monomeric subunits - monolignols linked together several covalent bonds. Numerous studies have shown monolignol biosynthesis polymerization to form tightly controlled tissues. However our understanding genetic...
Abstract Self‐incompatibility (SI) is a self‐recognition genetic system enforcing outcrossing in hermaphroditic flowering plants and results one of the arguably best understood forms natural (balancing) selection maintaining variation over long evolutionary times. A rich theoretical empirical population genetics literature has considerably clarified how distribution SI phenotypes translates into fitness differences among individuals by combination inbreeding avoidance rare‐allele advantage....
Abstract Histochemical screening of a flax ethyl methanesulfonate population led to the identification 93 independent M2 mutant families showing ectopic lignification in secondary cell wall stem bast fibers. We named this core collection Linum usitatissimum (flax) lbf mutants for lignified fibers and believe that represents novel biological resource investigating how fiber plants regulate lignin biosynthesis. As proof concept, we characterized lbf1 showed content increased by 350% outer...
Flax (Linum usitatissimum) bast fibres are located in the stem cortex where they play an important role mechanical support. They contain high amounts of cellulose and so used for linen textiles composite industry. In this study, we screened annotated flax genome identified 14 distinct synthase (CESA) genes using orthologous sequences previously identified. Transcriptomics 'primary cell wall' 'secondary CESA showed that some were preferentially expressed different organs tissues providing...
Abstract Background Flax ( Linum usitatissimum L.) is an economically important fiber and oil crop that has been grown for thousands of years. The genome recently sequenced transcriptomics are providing information on candidate genes potentially related to agronomically-important traits. In order accelerate functional characterization these we have generated a flax EMS mutant population can be used as TILLinG (Targeting Induced Local Lesions in Genomes) platform forward reverse genetics....
How two-component genetic systems accumulate evolutionary novelty and diversify in the course of evolution is a fundamental problem biology. In Brassicaceae, self-incompatibility (SI) spectacular example diversified allelic series which numerous highly diverged receptor-ligand combinations are segregating natural populations. However, mechanisms by new SI specificities arise have remained elusive. Using planta ancestral protein reconstruction, we demonstrate that two variants as distinct...
PIRIN2 (PRN2) was earlier reported to suppress syringyl (S)-type lignin accumulation of xylem vessels Arabidopsis thaliana. In the present study, we report yeast two-hybrid results supporting interaction PRN2 with HISTONE MONOUBIQUITINATION2 (HUB2) in Arabidopsis. HUB2 has been previously implicated several plant developmental processes, but not lignification. Interaction between and verified by β-galactosidase enzymatic co-immunoprecipitation assays. promoted deposition S-type secondary...
Abstract How two-components genetic systems accumulate evolutionary novelty and become diversified in the course of evolution is a fundamental problem biology. In Brassicaceae, self-incompatibility (SI) spectacular example allelic series which numerous highly diverged receptor-ligand combinations are segregating natural populations. However, mechanisms by new SI specificities arise first place have remained elusive. Using planta ancestral protein resurrection, we demonstrate that two...
