The fruit is used for the production of olive oil. The olive ( Olea europaea L.) is an important crop in Mediterranean countries. The functions of many of the transcripts obtained are intimately related, and most of them are of pivotal importance in defense, pollen-stigma interaction and signaling. The construction of SSH libraries using pistil and pollen, considering the high interaction between male-female counterparts, allowed the identification of transcripts with important roles in stigma physiology. Moreover, the unique presence of a representative number of these transcripts has been validated by means of qPCR approaches. The sequences and the differential expression level of the SSH-transcripts identified here, highly matched the transcriptomic information. Such lists were faced up to two recent datasets obtained in olive after transcriptomic and genomic approaches. Extensive lists containing information as regard to the specific transcripts determined for each stage and tissue are provided, as well as functional classifications of these gene products. Among them, those related to defense, transport and oxidative metabolism are highlighted mainly in the pistil libraries where transcripts related to stress, and response to biotic and abiotic stimulus have a prominent position. A variety of transcripts have been identified in the mature pollen grains and in the pistil at the receptive stage. Such libraries have also been created by subtracting vegetative mRNAs (from leaves), in order to identify reproductive sequences only. The use of subtractive SSH libraries constructed using, on the one hand one specific stage of the pistil development with germinating pollen grains, and on the other hand mature pollen grains may help to reveal the specific transcripts involved in the cited events. The purpose of the present study was to identify key gene products involved in the function of olive pollen and pistil, in order to help elucidate the events and signaling processes, which happen during the courtship, pollen grain germination, and fertilization in olive. Successful fertilization is mainly favored and sometimes needed of the presence of pollen grains from a different cultivar as the olive seizes a self-incompatibility system allegedly determined of the sporophytic type. Sexual reproduction in this plant is an essential process, which determines the yield. The olive tree is a crop of high socio-economical importance in the Mediterranean area. 5School of Biological Sciences, University of Bristol, Bristol, United Kingdom.4Departamento de Biología Molecular y Bioquímica, Universidad de Málaga, Málaga, Spain.3Departamento de Biologia, Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, São Paulo, Brazil.2Faculty of Health and Life Sciences, University of the West of England, Bristol, United Kingdom.1Plant Reproductive Biology Laboratory, Department of Biochemistry, Cellular and Molecular Biology of Plants, Estación Experimental del Zaidín, Consejo Superior de Investigaciones Científicas, Granada, Spain.We offer a variety of services from trimming to removal, stump grinding to planting, and also consultation with a certified Arborist.Adoración Zafra 1 ‡, Rosario Carmona 1 ‡, José A. As a result we are up to date on the current industry standards of tree safety and pruning. Additionally, all CTW's must pass a written examination in the areas of pruning, plant biology, cabling, planting, and safety. This certification requires a minimum of 18 months' experience as a tree climber, proof of training in aerial rescue, CPR, and first aid. The majority of our crew (12 of the 14) are Certified Tree Works. Our crew is very efficient, dedicated and knowledgeable.Here are Traverso Tree Service we value education.
