We hypothesized that red leaf margins reduce leaf herbivory by signalling to herbivorous insects the presence of increased chemical defences. •Leaves were collected from a natural population of Pseudowintera colorata. Margin size, herbivory damage, anthocyanin content and concentrations of polygodial, a... 2012-02-06T00:00:00Z http://www.newphytologist.com/details/journalArticle/1473215/Genomic_selection_for_growth_and_wood_quality_in_Eucalyptus_capturing_the_missin.html Summary •Genomic selection (GS) is expected to cause a paradigm shift in tree breeding by improving its speed and efficiency. By fitting all the genome‐wide markers concurrently, GS can capture most of the ‘missing heritability’ of complex traits that quantitative trait locus (QTL) and association mapping classically fail to explain. Experimental support of GS is now required. ... 2012-02-06T00:00:00Z http://www.newphytologist.com/details/journalArticle/1457363/Barley_mutants_with_low_rates_of_endosperm_starch_synthesis_have_low_grain_dorma.html Summary •Studies of embryo dormancy in relation to preharvest sprouting (PHS) in cereals have focused on ABA and other hormones. The relationship between these phenomena and the rate of grain filling has not been investigated. •A collection of barley mutants impaired in starch synthesis was assessed for preharvest sprouting in the field. In subsequent glasshouse experiments,... 2012-02-02T00:00:00Z http://www.newphytologist.com/details/journalArticle/1457365/Combined_use_of__13_C__18_O_and__15_N_tracks_nitrogen_metabolism_and_genotypic_a.html Summary •Accurate phenotyping remains a bottleneck in breeding for salinity and drought resistance. Here the combined use of stable isotope compositions of carbon (δ13C), oxygen (δ18O) and nitrogen (δ15N) in dry matter is aimed at assessing genotypic responses of durum wheat under different combinations of these stresses. •Two tolerant and two susceptible genotypes to salinity were grown under... 2012-02-02T00:00:00Z http://www.newphytologist.com/details/journalArticle/1457377/Safe_sex_in_plants.html 2012-02-02T00:00:00Z http://www.newphytologist.com/details/journalArticle/1457379/Issue_Information.html 2012-02-02T00:00:00Z http://www.newphytologist.com/details/journalArticle/1457387/A_molecular_guide_to_the_taxonomy_of_arbuscular_mycorrhizal_fungi.html 2012-02-02T00:00:00Z http://www.newphytologist.com/details/journalArticle/1457419/The_New_Phytologist_Tansley_medal_2011.html 2012-02-02T00:00:00Z http://www.newphytologist.com/details/journalArticle/1456751/Expression_of_a_bacterial_feedbackinsensitive_3deoxy_d_arabinoheptulosonate_7pho.html Summary •The shikimate pathway of plants mediates the conversion of primary carbon metabolites via chorismate into the three aromatic amino acids and to numerous secondary metabolites derived from them. However, the regulation of the shikimate pathway is still far from being understood. We hypothesized that 3‐deoxy‐d‐arabino‐heptulosonate 7‐phosphate synthase (DAHPS) is a key enzyme regulating flux through the shikimate... 2012-02-01T00:00:00Z http://www.newphytologist.com/details/journalArticle/1456753/Do_thick_leaves_avoid_thermal_damage_in_critically_low_wind_speeds.html Summary •Transient lulls in air movement are rarely measured, but can cause leaf temperature to rise rapidly to critical levels. The high heat capacity of thick leaves can damp this rapid change in temperature. However, little is known about the extent to which increased leaf thickness can reduce thermal damage, or how thick leaves would need to be to have biological significance. We evaluated... 2012-02-01T00:00:00Z http://www.newphytologist.com/details/journalArticle/1456755/Abscisic_acid_mediates_the_formation_of_a_suberized_stem_scar_tissue_in_tomato_f.html Summary •During harvest, fleshy berry tomato fruits (Solanum lycopersicum) were wounded at their stem scar. Within 3 d, this wound was rapidly sealed by a process covering the wound site with a membranous layer which effectively protects the tomato fruit from excessive water loss, nutrient elution and the entry of pathogens. •Chemical analysis of the de novo synthesized stem scar tissue revealed... 2012-02-01T00:00:00Z http://www.newphytologist.com/details/journalArticle/1456229/Toxic_cardenolides_chemical_ecology_and_coevolution_of_specialized_plantherbivor.html Contents   Summary 1 I.
