The present study was carried out to verify the statistical relationships between the characteristic parameters in terms of vegetative aerial architecture of the date palms for simulating realistic 3D models. The vegetal material was composed of two Tunisian varieties of Phoenix dactylifera L., ＂Barhi＂ and ＂Rochdi＂. The observations are taken place in Gabes and on one pair of palms per main stem and offshoot for each cultivar. The analysis of the characteristic dimensions of the pinnae and rachis allowed the determination of a minimum sample. The geometrical analysis confirmed the existence of a strong correlation between rotation angles and radial angles. The architectural analysis of the two Tunisian cultivars revealed that the distribution of characteristic parameter values of pinnae was the outcome ofa regionalized variable along the rachis. This statistical study of relationships between the characteristic parameters in terms of vegetative aerial architecture of the two varieties allows executing a new measurement protocol for computing and simulating realistic 3D models.

The acrostyle is a distinct anatomical region present on the cuticle at the inner face of the common food/salivary canal at the tip of aphid maxillary stylets. This conserved structure is of particular interest as it harbors the protein receptors of at least l plant virus, Cauliflower mosaic virus＇, and presumably has other roles in plant-insect interactions. Previously we reported immunolabeling of a highly conserved motif of cuticular proteins from the CPR family （named for the presence of a Rebers and Riddiford consensus） within the acrostyle. Here we report the development of novel tools to further study the proteomic composition of this region and to identify proteins involved in insect- virus interactions. Using a series of antibodies against cuticular proteins from the RR-2 subfamily, we identified additional peptides present within the acrostyle. Our results demonstrated that the acrostyle is a complex structure containing multiple domains of cuticular proteins accessible for interaction. In addition, an array of overlapping peptides,which covers the diversity of the majority of the RR-2 subfamily, was ~tevelopect as a generic tool to characterize cuticular protein/pathogen interactions. Upon probing this array with Cucumber mosaic virus particles, consensus peptide sequences from hybridizing peptides were identified. Use of these novel tools has extended our knowledge of the proteomic composition of insect maxillary stylets and identified sequences that could be involved in virus binding, thus contributing to further elucidation of the various properties and functions of the acrostyle.
