Indirect Estimation of Genetic Structure and Gene Flow in Some Black Poplar (Populus Nigra) Clones using Leaf Morphophysiological Traits

BACKGROUND The plant microbiome represents one of the key determinants of plant health and productivity by providing a plethora of functional capacities such as access to low-abundance nutrients, suppression of phytopathogens, and resistance to biotic and/or abiotic stressors. However, a robust understanding of the structural composition of the bacterial microbiome present in different plant mi...

Wood is one of the promising bioenergy feedstocks for lignocellulosic biofuel production. Understanding how wood components are synthesized will help us design strategies for better utilization of wood for biofuel production. One of the major wood components is xylan, in which about 10% of xylosyl residues are substituted with glucuronic acid (GlcA) side chains. All the GlcA side chains of xyla...

Populus x canadensis clone I-214 exhibits a general indicator phenotype in response to excess Zn, and a higher metal uptake in roots than in shoots with a reduced translocation to aerial parts under hydroponic conditions. This physiological adaptation seems mainly regulated by roots, although the molecular mechanisms that underlie these processes are still poorly understood. Here, differential ...

during the study on rust mycobiota of central alborz, several rust infected specimens belonging to salicaceae family including populus and salix species were investigated. populus nigra, p. euphratica, saix alba and s. excelsa were infected by various melampsora species. uredinial (ii) and telial (iii) stages of rust were present on infected plants. according to morphological characters, five f...

Bu çalışmada; Antik Roma Cumhuriyeti ve Populus Romanus denilen Halkı’nın genel karakteri üzerinde durulmuştur. Ayrıca Cumhuriyet’in kurulmasına giden süreçte rolü irdelenmiştir. Latince’de “Populus” terimi “Halk” anlamına gelmekte olup, ile de Halkı kastedilmektedir. patrici pleb adı verilen iki temel sınıftan oluşmaktadır. sınıf devletinin idari yapısının belirlenmesinde rol oynamıştır. bağla...

Gene-derived simple sequence repeats (genic SSRs), also known as functional markers, are often preferred over random genomic markers because they represent variation in gene coding and/or regulatory regions. We characterized 544 genic SSR loci derived from 138 candidate genes involved in wood formation, distributed throughout the genome of Populus tomentosa, a key ecological and cultivated wood...

Wood formation in trees requires carbon import from the photosynthetic tissues. In several tree species, including Populus species, the majority of this carbon is derived from sucrose (Suc) transported in the phloem. The mechanism of radial Suc transport from phloem to developing wood is not well understood. We investigated the role of active Suc transport during secondary cell wall formation i...
