ABSTRACT The long‐term effect of elevated atmospheric CO 2 on isoprenoid emissions from adult trees two Mediterranean oak species (the monoterpene‐emitting Quercus ilex L. and the isoprene‐emitting pubescens Willd.) native to a high‐CO environment was investigated. During consecutive years, emission monitored both at branch level, measuring actual under natural conditions, leaf basal standard conditions 30 °C light intensity 1000 µ mol m −2 s −1 . Long‐term exposure high levels did not...
Abstract Plant roots interact with a wide variety of rhizospheric microorganisms, including bacteria and the symbiontic arbuscular mycorrhizal (AM) fungi. The symbiosis represents series complex feedbacks between plant fungus regulated by their physiology nutrition. Despite widespread distribution ecological significance AM symbiosis, little is known about potential fungi to affect VOC metabolism. purpose this study was investigate whether colonization associated soil microorganisms affects...
The use of formalin constitutes serious health hazards for laboratory workers. We investigated the suitability and performance ethanol-based fixative, FineFIX, as a substitute anatomical cellular structure investigations leaves by light microscopy leaf surface ultrastructural analysis scanning electron (SEM). compared features materials prepared using conventional fixation with FineFIX. Leaves were collected from ornamental tree species commonly used in urban areas. FineFIX was also...
Abstract Auxin is the mobile signal controlling rate of growth and specific aspects development plants. It has been known for over a century that auxins act as messenger linking plant to environmental changes. An often overlooked aspect how this accomplished effect environment on metabolism major auxin, indole-3-acetic acid (IAA). We have studied IAA in relation one variable, temperature. The model system used was an inbred line aquatic monocot Lemna gibba G-3, 3F7-11 grown at temperatures...
The general aim of this work was to compare the leaf-level responses different protective components water deficit and high temperatures in Quercus cerris L. robur Several biochemical osmotic adjustment antioxidant system were investigated together with changes hormones. Q. seedlings responded by: (1) activating a pattern osmoregulation mechanisms depending on species nature stress; (2) upregulating synthesis newly-explored osmoprotectant, dimethylsulphoniopropionate (DMSP); (3) trading-off...
The clone EMB-2 of the interspecific hybrid Helianthus annuus x H. tuberosus provides an interesting system to study molecular and physiological aspects somatic embryogenesis. Namely, in addition non-epiphyllous (NEP) leaves that expand normally, produces epiphyllous (EP) bearing embryos on adaxial surface. This was used investigate if ectopic expression LEAFY COTYLEDON1-LIKE (Ha-L1L) gene auxin activity are correlated with establishment embryogenic competence.Ha-L1L evaluated by...
This study focuses on several aspects of communication strategies adopted by adults the Mediterranean flat-headed root-borer Capnodis tenebrionis (Coleoptera: Buprestidae). Morphological studies structures involved in mate recognition and acceptance revealed presence porous areas pronota both sexes. These were variable shape size, but proportionally larger males. The chaetic, basiconic coeloconic sensilla antennae males females was verified. Bioassays stereotyped rituals involvement female...
Plant lateral organs such as leaves arise from a group of initial cells within the flanks shoot apical meristem (SAM). Alterations in initiation are often associated with changes dimension and arrangement SAM well abnormal hormonal homeostasis. A mutation named stem fasciated (stf) that affects various aspects plant development, including shape auxin level, was characterized sunflower (Helianthus annuus).F1, F2 F3 generations were obtained through reciprocal crosses between stf normal...
