Variation in drought resistance and its relationship with adaptive and physiological traits in forest trees are important in choosing suitable seed sources for reforestation and afforestation programs. A common garden experiment using 240 half-sib families originating from coastal and inland populations of Turkish red pine (Pinus brutia) in Turkey was set up with three replicates. The aims were to determine variation of drought damage, height growth, and phenology among populations and to investigate the relationship between drought damage and physiological traits (i.e. plant moisture stress and proline content). Three-year-old seedlings were subjected to drought treatment during the summer of 2000 and adaptive and physiological traits were measured. Except for bud burst, the majority of the variation resided between populations, leading to low heritability estimates for all traits. On average, inland populations were more resistant to drought and taller, with earlier bud burst and bud set times, than coastal populations. Proline content increased with higher drought damage, especially in cold-resistant and inland families. Inland populations are more drought-resistant than coastal populations. The results of the study demonstrate the possibility of selection for drought resistance for Turkish red pine at the population level.


Genetic and physiology of cold and drought resistance in Turkish red pine (Pinus brutia, Ten.) populations from southern Turkey
Kandemir, Gaye Eren; Kaya, Zeki; Önde, Sertaç; Department of Biology (2002)
The purpose of the study was to determine the pattern of genetic variation in morphological and physiological traits associated with cold and drought stress using seedling from over-exploited and natural populations of Pinus brutia Ten. (Turkish red pine) from southern Turkey. To determine the pattern of genetic variation existing in over-exploited and natural populations, seedlings from 6 populations each with 40 families were raised in Ankara forest nursery from 1998-2000. Three of the populations (Yaylaa...
Gene regulation network behind drought escape, avoidance and tolerance strategies in black poplar (Populus nigra L.)
Yildirim, Kubilay; Kaya, Zeki (2017-06-01)
Drought is the major environmental problem limiting the productivity and survival of plant species. Here, previously identified three black poplar genotypes having contrasting response to drought were subjected to gradual soil water depletion in a pot trial to identify their physiological, morphological and antioxidation related adaptations. We also performed a microarray based transcriptome analyses on the leaves of genotypes by using Affymetrix poplar Genome Array containing 56,000 transcripts. Phenotypic...
A Proteomic approach to the comparison of two pine species: proteomes of pinus brutia and pinus sylvestris under environmental stress
Yılmaz, Can; İşcan, Mesude; Güray, Tülin; Department of Biochemistry (2013)
Drought and cold are environmental factors that affect the development and dispersion of plant species. In this study, two pine species adapted to different environmental conditions: Pinus brutia Ten. (Turkish red pine) and Pinus sylvestris L. (Scots pine) were subjected to a proteome research under those stresses. 20 trees from each species, located in the same region and elevation at Yalıncak area in METU Campus, were marked and sampled for their needles, three times in a year: at the end of dry and hot s...
Changes of Eutrofication Indicator Parameters (TP, DIN, Chl-a and TRIX) in the Cilician Basin (Northeast Mediterranean)

Eutrophication processes and changes in coastal ecosystem are determined by the coastal/open sea interactions and rates of nutrient pollution. The Cilician Basin shelf waters are affected not only by intense industrial activities and increased population, but also by complex atmosphere-sea-land interactions. There is a recognizable difference between water qualities of Mersin bay coastal and the Cilician open waters depleted in nutrients. Eutrophic conditions have developed in the eastern bay shallow waters...
Individual and combined effect of drought and heat stresses in contrasting potato cultivars overexpressing miR172b-3p

MicroRNAs (miRNAs) are essential players of plant defence systems because of their involvement in reprogramming gene expression under adverse environmental conditions including drought and heat, which are considered major players in limiting crop productivity. miR172b-3p was previously determined as a remarkable stress-responsive miRNA in our next-generation sequencing (NGS) analysis in potato. This study aims to understand the functions of miR172b-3p and its target (ERTF RAP2-7-like) under drought, heat, a...
