comTAR: a web tool for the prediction and characterization of conserved microRNA targets in plants [PDF]

, 2014
Motivation: MicroRNAs (miRNAs) are major regulators of gene expression in plants and animals. They recognize their target messenger RNAs (mRNAs) by sequence complementarity and guide them to cleavage or translational arrest.

Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

New Phytologist, EarlyView.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

PWO proteins are associated with PRC2 since their emergence in vascular plants

New Phytologist, EarlyView.
Summary The Polycomb repressive complex 2 (PRC2), a conserved histone methyltransferase complex, plays a central role in transcriptional silencing across eukaryotes. Here, we investigate the evolution of PWWP‐DOMAIN INTERACTORS OF POLYCOMBS (PWOs), which interact with PRC2, and examine the conservation of the PWOs‐PRC2 interaction across plant ...

Structural studies of a fucogalactoxyloglucan from pinus radiata primary cell walls : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]

, 1980
1. The changes in carbohydrate composition of elongating Pinus radiata primary cell walls were investigated. In the hemicellulose B extracts, a large increase in the percentage of non-starch, non-cellulosic, glucose was found to occur on cessation of ...

Integrated transfers of terrigenous organic matter to lakes at their watershed level: A combined biomarker and GIS analysis [PDF]

, 2010
Terrigenous organic matter (TOM) transfer from a watershed to a lake plays a key role in contaminants fate and greenhouse gazes emission in these aquatic ecosystems.

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

New Phytologist, EarlyView.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Are sexes natural kinds? [PDF]

, 2021
Asking whether the sexes are natural kinds amounts to asking whether the categories, female and male, identify real divisions in nature, like the distinctions between biological species, or whether they mark merely artificial or arbitrary distinctions ...

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

New Phytologist, EarlyView.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.

The taxonomic compound and the systematic of Gymnosperms (Pinophyta) of the dendroflora of Ukraine on the basis of their modern classification

Інтродукція Рослин, 2013
The new international classification of gymnosperms is adduce in the publication. This classification was proposed by the group of scientists with registration of the analysis of DNA structure, morphological, phylogenetics and other investigations ...

ATXR5 and ATXR6 are H3K27 monomethyltransferases required for chromatin structure and gene silencing. [PDF]

, 2009
Constitutive heterochromatin in Arabidopsis thaliana is marked by repressive chromatin modifications, including DNA methylation, histone H3 dimethylation at Lys9 (H3K9me2) and monomethylation at Lys27 (H3K27me1).
