In vitro propagation of Tilia platyphyllos by axillary shoot proliferation
In vitro propagation of Tilia platyphyllos Scop. has been achieved by axillary shoot proliferation and somatic embryogenesis. The influence of tree age, explant source, genotype, and phytohormones on micropropagation of juvenile and mature trees of Tilia platyphyllos has been investigated. Nodal segments and shoot tips were used as initial explants for axillary shoot proliferation. Low concentr...
متن کاملSINGLET OXYGEN RESISTANT 1 links reactive electrophile signaling to singlet oxygen acclimation in Chlamydomonas reinhardtii.
Acclimation of Chlamydomonas reinhardtii cells to low levels of singlet oxygen, produced either by photoreactive chemicals or high light treatment, induces a specific genetic response that strongly increases the tolerance of the algae to subsequent exposure to normally lethal singlet oxygen-producing conditions. The genetic response includes the increased expression of various oxidative stress ...
متن کاملAcclimation to singlet oxygen stress in Chlamydomonas reinhardtii.
In an aerobic environment, responding to oxidative cues is critical for physiological adaptation (acclimation) to changing environmental conditions. The unicellular alga Chlamydomonas reinhardtii was tested for the ability to acclimate to specific forms of oxidative stress. Acclimation was defined as the ability of a sublethal pretreatment with a reactive oxygen species to activate defense resp...
متن کاملSinglet Oxygen Reactions with Flavonoids. A Theoretical – Experimental Study
Detection of singlet oxygen emission, λ(max) = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, k(T), and the reactive reaction rate constant, k(r), for the reaction between singlet oxygen and several flavonoids. Values of k(T) determined in deuterated water, ranging from 2.4×10(7) M(-1) s(-1) to 13.4×10(7) M(-1) s(-1), for ...
متن کاملCharacterization of microsatellite loci in Tilia platyphyllos (Malvaceae) and cross-amplification in related species1
UNLABELLED PREMISE OF THE STUDY Microsatellite markers in the genus Tilia were developed to investigate the genetic variation in T. platyphyllos and its relationship with T. cordata. • METHODS AND RESULTS Fifteen microsatellite markers were developed using a microsatellite enrichment protocol. Most loci show a high level of polymorphism in two T. platyphyllos populations from France. The n...
