“…In this work SSR analysis has been used to define genetic relationships between domesticated and wild accessions. We conclude that the use of this codominant marker is a good tool to estimate genetic relationships among domesticated as well as wild accessions, to solve cases of homonymies and synonymies, to fingerprint varieties, and to search or confirm parents of prominent grapevines varieties as also shown in previous papers (Bowers et al 1999;Labra et al 1999;Labra et al 2001c;Anthony et al 2002).…”

The origin of the grapevine was investigated with archaeobotanical, cultural and historical data. A primary domestication centre was located in the Near East region but there is no agreement on the existence or role of secondary domestication centres. In this work, PCR-based microsatellite analysis has been applied to study the origin of some Italian cultivated grapevines from in situ direct domestication of the wild autoctonous grapevine. Three different Italian locations in Grosseto, Cosenza and Nuoro were identified for this study, and domesticated grapevine as well as wild local accessions growing in these location, were analysed by SSR markers. Cluster analysis performed on Cosenza and Grosseto samples showed a high value of genetic distance between domesticated and wild accessions. On the contrary two cultivars (Bovale Murru and Bovale Muristellu) recovered in Nuoro (in the Sardinia island) were very close to some wild varieties. This suggests that the latter two cultivars may have originated from wild grapevines and consequently that in this location a secondary grapevine domestication event occurred. Six Lambrusco varieties were also included in this analysis as ancient putative ancestors of the cultivated grapevines. The molecular analysis excluded this hypothesis and suggest Lambrusco as an independent Vitis taxon.

“…Although the pulp sample was from the same species as Urbaneja et al (1996), Coffea arabica, multiple cultivar varieties exist, and these varieties exhibit differences in both growth habit and yield (Anthony et al 2002). Additionally, coffee berries are harvested at varying stages of ripeness.…”

The present paper investigated the technical possibilities of bioethanol production from coffee pulp in a sustainable manner. Coffee pulp is a largely underutilized waste stream and has the potential to become a bioethanol feedstock if processing is economically viable. This study aimed to characterize the chemical composition of coffee pulp with relevance to bioethanol production and to compare results to other bioethanol feedstocks. Based on the total sugar yield, we investigated bioethanol production using AspenPlus simulation software. In the sugar characterization part, total carbohydrates were measured after complete acid hydrolysis of dry pulp, while water-soluble carbohydrates were measured after acid hydrolysis of soxhlet extracted solutions. Moisture, lignin, and ash contents were measured gravimetrically after appropriate heating treatments. The results showed sugar contents, expressed as percentages of dry mass, as follows: 5.8, 5.2, 20.2, 4.2, and 4.7 % for arabinose, galactose, glucose, xylose, and mannose, respectively. Arabinose, galactose, and glucose were the only water-extracted simple sugars, at 1.0, 1.4, and 2.6 % of dry mass, respectively. AspenPlus simulation was based on processing 10,000 ton/day of coffee pulp. The results demonstrated sugar and ethanol yield of 2100 and 1050 ton/day, respectively. This would make annually profit of $0.13 million. The simulation estimated the capital investment cost was about $2 million. In order to satisfy the process economy, the process operation cost must be operated at minimum of $1.87 million annually. The life-cycle analysis showed the net value of energy of the whole process is an economical as well as the balance of CO 2 emission/reduction was on the environmental favor.

“…Coffea arabica 'Laurina' Hort Ex Cramer, named 'Bourbon pointu' (BP), is a natural mutant of the 'Bourbon' (B) variety introduced to Réunion Island in the eighteenth century (Anthony et al 2002;Haarer 1956;Lécolier et al 2009a). The mutation laurina is monolocus, Mendelian, and recessive (Krug 1949;Krug and Carvalho 1951;Krug et al 1954), but is also characterized by frequent reversions and pleiotropic effects (Chevalier 1947).…”

The two varieties-Bourbon (B) and its natural mutant Bourbon pointu (BP)-of Arabica coffee (Coffea arabica L.) differ by an epigenetic, monolocus, and recessive laurina mutation that results in pleiotropic effects, such as tree dwarfism and tree-shape modification. The objective of the study was to search for the origin of the differences in size and shape of the tree both at the macroscopic (length and number of internodes, branching angle) and at the microscopic levels (size and number of cells within the internode pith). At the macroscopic level, the laurina mutation acted only by decreasing the internode size. Neither the angle of branching nor the number of internodes was influenced by the mutation. At the microscopic level, the mutation lowered mainly the number of cells present along the longitudinal axis of the internode, and, at a lesser extent, the cell height. Especially, the internode size decreasing explained both the tree dwarfism and the tree-shape modification. In fact, the laurina mutation strengthened the dwarfism of plagiotropic internodes when compared to that of the orthotropic ones, and such an impact was mainly due to a strong cell number decrease. To summarize, two major pleiotropic effects of the laurina mutation can be explained only by a modification of the trade-off between meresis and auxesis during the internode growth. This opens new perspectives for the characterization of the other effects at the hormonal level, and then, for the identification of the gene at the molecular level.
