Main conclusionEndophytes reside in different parts of the poppy plant and perform the tissue-specific functions. Most leaf endophytes modulate photosynthetic efficiency, plant growth, and productivity while capsule endophytes modulate alkaloid biosynthesis. Endophytes promote plant growth, provide protection from environmental stresses and are the...
Main conclusionSCARECROW controls Arabidopsis root meristem size from the root endodermis tissue by regulating the DELLA protein RGA that in turn mediates the regulation ofARR1levels at the transition zone. Coherent organ growth requires a fine balance between cell division and cell differentiation. Intriguingly, plants...
Main conclusionThe work demonstrates a relationship between the biosynthesis of the secondary metabolite, agatharesinol, and cytological changes that occur in ray parenchyma during cell death in sapwood sticks ofCryptomeria japonicaunder humidity-regulated conditions. To characterize the death of ray parenchyma...
Main ConclusionThe latex fromThevetia peruvianais rich in plant defense proteins, including a 120kDa cysteine peptidase with structural characteristics similar to germin-like proteins. More than 20,000 plant species produce latex, including Apocynaceae, Sapotaceae, Papaveraceae and Euphorbiaceae. To better...
Main conclusionTwoTFL1-like genes,CorfloTFL1andCorcanTFL1cloned fromCornus floridaandC. canadensis,function in regulating the transition to reproductive development in...
Main conclusionOsPGIP4overexpression enhances resistance to bacterial leaf streak in rice. Polygalacturonase-inhibiting proteins are thought to play important roles in the innate immunity of rice against fungi. Here, we show that the chromosomal location of OsPGIP4 coincides with the major bacterial leaf streak resistance quantitative...
Main conclusionOverexpression of chalcone-3-hydroxylase provokes increased accumulation of 3-hydroxyphloridzin inMalus. Decreased flavonoid concentrations but unchanged flavonoid class composition were observed. The increased 3-hydroxyphlorizin contents correlate well with reduced susceptibility to fire blight and scab. ...
Main conclusionCold-acclimation genes in woody dicots without winter-dormancy, e.g., olive-tree, need investigation. Positive relationships betweenOeFAD8, OeOSM, andOeLIP19and olive-tree cold-acclimation exist, and couple with increased lipid unsaturation and cutinisation....
Main ConclusionIn the present study, miRNA precursors in the genomes of three palm species were identified. Analyzes of sequence conservationand biological function of their putative targets contribute to understand the roles of miRNA in palm biology. MicroRNAs are small RNAs of 20–25 nucleotides in length, with important functions in...
Main ConclusionA significant number of epigenetic regulators were differentially expressed during embryogenesis at different epitype-inducing conditions. Our results support that methylation of DNA and histones, as well as sRNAs, are pivotal for the establishment of the epigenetic memory. As a forest tree species with long generation times, Norway...
Main conclusionThe present study showed all the 16 strains isolated and identified from the alfalfa rhizosphere and nodules, and registered in GenBank, to be good candidates for targeted use in studies addressing the rather weak known mechanism of plant growth promotion, including that ofMedicago truncatula,a molecular crop model....
Main conclusionNew wheat-Secale africanumchromosome 5Rasubstitution and translocation lines were developed and identified by fluorescence in situ hybridization and molecular markers, and chromosome 5Raspecific genes responsible for grain hardness were isolated...
Main conclusionTwo types of lignins occurred in different lignin–carbohydrate fractions, a lignin enriched in syringyl units, less condensed, preferentially associated with xylans, and a lignin with more guaiacyl units, more condensed, associated with glucans. Lignin–carbohydrate complexes (LCC) were isolated from the fibers of sisal (Agave sisalana) and abaca (Musa textilis...
Main conclusionRipening initiation-associated hormonal changes and sugar accumulation for individual fruits differed by seed content and did not depend heavily on flowering time or duration from anthesis to clusters’ onset of ripening. For Vitis vinifera, the ripening initiation of individual fruits in a cluster occurs unevenly. This developmental...
Main conclusionThis study demonstrates a dose-dependent response ofTrichoderma harzianumTh-56 in improving drought tolerance in rice by modulating proline, SOD, lipid peroxidation product andDHN/AQUtranscript level, and the growth attributes. ...
Main conclusionThe present review discusses the roles of repetitive sequences played in plant sex chromosome evolution, and highlights epigenetic modification as potential mechanism of repetitive sequences involved in sex chromosome evolution. Sex determination in plants is mostly based on sex chromosomes. Classic theory proposes that sex chromosomes...
