Abstract Atmospheric warming and increasing tropospheric ozone (O3) concentrations often co-occur in many cities of the world including China, adversely affecting health status urban trees. However, little information is known about combined interactive effects from increased air temperature (IT) elevated O3 (EO) exposures on tree species. Here, Ginkgo biloba Populus alba ‘Berolinensis’ seedlin...

Bu çalışmada; sarıçam (Pinus slyvestris L) %40, sapsız meşe (Quercus petraea %30, kavak (Populus alba) %20 ve talaş %10 oranlarında hammadde kullanılmıştır. Karışım biokütle çiplerine 1.35 mol üre-formaldehit yapıştırıcısı, sertleştirici parafin eklenmiştir. Yonga levhalar; P1, P2, P3 P4 üretim parametrelerine göre üretilmiştir. Üretilen yonga levhaların mekanik özelliklerinin test sonuçları in...

Trees are long-lived organisms that continuously adapt to their environments, a process in which epigenetic mechanisms likely play key role. Via downregulation of the chromatin remodeler DECREASED IN DNA METHYLATION 1 (DDM1) poplar (Populus tremula × Populus alba) RNAi lines, we examined how methylation coordinates genomic and physiological responses moderate water deficit. We compared growth d...

We tested two genes together in hybrid poplars (genus Populus), CP4 and GOX, for imparting tolerance to glyphosate (the active ingredient in Roundup® herbicide). Using Agrobacterium-based transformation, 80 independent transgenic lines (i.e., products of asexual gene transfer) were produced in a variety of hybrid poplar clones (40 lines in Populus trichocarpa Torr. & Gray × Populus deltoides Ba...

Caffeoyl coenzyme A O-methyltransferase (CCoAOMT) has recently been shown to participate in lignin biosynthesis in herbacious tobacco plants. Here, we demonstrate that CCoAOMT is essential in lignin biosynthesis in woody poplar (Populus tremula x Populus alba) plants. In poplar stems, CCoAOMT was found to be expressed in all lignifying cells including vessel elements and fibers as well as in xy...

The mechanisms responsible for the origin, maintenance and evolution of plant secondary metabolite diversity remain largely unknown. Decades of phenotypic studies suggest hybridization as a key player in generating chemical diversity in plants. Knowledge of the genetic architecture and selective constraints of phytochemical traits is key to understanding the effects of hybridization on plant ch...

Various regulatory proteins play a fundamental role to manage the healthy plant growth under stress conditions. Differential display reverse transcriptase PCR and random amplification of cDNA ends (RACE) was used to explore the osmotic stress-responsive transcripts. We identified and characterized the salt stress-responsive R2R3 type RMYB transcription factor from Hibiscus sabdariffa which has ...
