Modulation of bud survival in Populus nigra sprouts in response to water stress-induced embolism.
Understanding drought tolerance mechanisms requires knowledge about the induced weakness that leads to tree death. Bud survival is vital to sustain tree growth across seasons. We hypothesized that the hydraulic connection of the bud to stem xylem structures was critical for its survival. During an artificial drastic water stress, we carried out a census of bud metabolic activity of young Populu...
متن کاملIntraspecific variation of physiological and molecular response to cadmium stress in Populus nigra L.
Little is known about the variability of response to heavy metal stress within tree species, although it could be a key for a better understanding of tolerance mechanisms and for breeding. The aim of the present study was to characterize the natural variation of response to cadmium (Cd) in Populus nigra L. in order to understand the mechanisms of Cd tolerance. For that, two P. nigra genotypes, ...
متن کاملDifferentially expressed genes in Populus simonii x Populus nigra in response to NaCl stress using cDNA-AFLP.
Salinity is an important environmental factor limiting growth and productivity of plants, and affects almost every aspect of the plant physiology and biochemistry. The objective of this study was to apply cDNA-AFLP and to identify differentially expressed genes in response to NaCl stress vs. no-stress in Populus simonii x Populus nigra in order to develop genetic resources for genetic improveme...
متن کاملSex-Specific Response to Stress in Populus
Populus is an effective model for genetic studies in trees. The genus Populus includes dioecious species, and the differences exhibited in males and females have been intensively studied. This review focused on the distinctions between male and female poplar and aspen plants under stress conditions, such as drought, salinity, heavy metals, and nutrient deficiency on morphological, physiological...
متن کاملVariation in Bud Exudate Composition of Populus nigra Assessed by Gas Chromatography-Mass Spectrometry
Bud exudates from twelve clones o f Populus nigra originating from seven countries were analyzed by gas chromatography-mass spectrometry and the principal compounds identified. Specimens o f P. nigra var betulifolia differed in bud exudate composition from the other speci mens analyzed, and were more similar in exudate composition to P. deltoides than were the other specimens. The range o f bu...
