Etude de l'organisation du génome de l'éspèce Aegilops peregrina (Hackel) Maire et Weiller BENAMARA Meriem; Khalfallah Nadra To establish (syn. Aegilops the karyotype variabiUs of specie Eig. 2n Aegilops = 4x 28peregrina chromosomes) (Hackel) weMaire have used classical cytogenetic methods (Feulgen and silver staining) and molecular cytogenetic methods like: fluorochrom bandnig (chromomycine A3), fluorescent in situ hybridization of 18S-26S rDNA, 5S rDNA and repetitive sequences. *1 I •— n Rl Coloration with Feulgen has revealed that this karyotype is composed of 05metacentric pairs, 08 submetacentric pairs which 3 pocess satellites and 1 subtelocentic pair. The number of satellites corresponds to the number of nucleolus per cell and to the actif NORs revealed by silver staining. Heterochromatic bands rich with G-C were detected on telomeric regions of some chromosomes by the coloration of chromomycine A3. Two nucleolus organizing regions (NORs) on chromosomes 12 SU and 14 SU corresponding to 18S-26S rDNA and two sites corresponding to 5S rDNA on the telomeric regions was detected by in situ hybridization. The hybridization with the PSc119.2 probe permitted to locate repetitive DNA sequences on telomeric regions of 13 chromosomes from Ae. Peregrina. 86 f.

Ecologie de l’ailante glanduleux (Ailanthus altissima) dans la région de Constantine Alatou Djamel; Soltani Amri Amel Biological invasions are a concern of current as well as climate change. Indeed, they can be regarded as an experimental manipulation of biodiversity on a large scale and used to test fundamental hypotheses in ecology. In particular, they allow exploration of impaired functioning of ecosystems by altering species assemblage. This work is to determine the adaptability of the ailanthus dwarf capacity in the region of Constantine, thermal variability for using biochemical markers (chlorophyll, sugars and proline) and the assessment of its ecological character physico-chemical characterization of the soil. The seedlings under semi controlled under stress of short duration (03 hours) at a temperature ranging from 30°C to 50°C and in which the biochemical parameters are quantized (chlorophyll, sugars and proline). The results show that the seed of Ailanthus are capable to accumulate different osmolytes like proline and sugars in the various organs in response to thermal stress and the highest levels are stored in the roots for the proline and in leaves for sugars reflecting the resistance of this species to the stress. The physicochemical characterization of the environment reveals a high C/N ratio reflecting very favorable conditions for the decomposition of the carbonaceous material and very low levels of trace metals that reflect the geochemical background elements. thus, the species studied showed a good ability to grow in the study site. 86 f.
