Sem Analyses

Plums are affected by a cancerous disease called “Black Knot disease” caused by the fungus Apiosporina morbosa. It affects both Japanese (Prunus salicina) and European plums (Prunus domestica) equally. In order to understand the spread of the disease, histological analysis was performed in two different European plum cultivars (susceptible and tolerant). Light and Scanning Electron Microscope (SEM) analyses confirmed the presence of the growing hyphae in the internal tissues of the susceptible trees. By using stereoscopic analysis with a fluorescence filter, we were able to detect the hyphae in the visible lesion area. At about 2 inches from above and below the knots, no spore or hypha was visible with the light microscope. However, SEM images showed strong evidence that the fungus is capable of migrating to adjacent vessels in the susceptible plum genotype. In fact, at that distance below and above the knots, conidia were detected inside xylem vessels suggesting a systemic movement of the fungus that has not been shown so far. No symptoms were observed in the resistant genotype. Starch granules, vessel occlusions and lipid droplets were the main distinguishable characteristics between susceptible and tolerant varieties.

Prunus Salicina

The genetic diversity of 14 Japanese plum (Prunus salicina Lindl) landraces adapted to an ecosystem of alternating flooding and dry conditions was characterized using neutral simple sequence repeat (SSR) markers. Twelve SSRs located in six chromosomes of the Prunus persica reference genome resulted to be polymorphic, thus allowing identification of all the evaluated landraces. Differentiation between individuals was moderate to high (average shared allele distance (DAS) = 0.64), whereas the genetic diversity was high (average indices polymorphism information content (PIC) = 0.62, observed heterozygosity (Ho) = 0.51, unbiased expected heterozygosity (uHe) = 0.70). Clustering and genetic structure approaches grouped all individuals into two major groups that correlated with flesh color. This finding suggests that the intuitive breeding practices of growers tended to select plum trees according to specific phenotypic traits. These neutral markers were adequate for population genetic studies and cultivar identification. Furthermore, we assessed the SSR flanking genome regions (25 kb) in silico to search for candidate genes related to stress resistance or associated with other agronomic traits of interest. Interestingly, at least 26 of the 118 detected genes seem to be related to fruit quality, plant development, and stress resistance. This study suggests that the molecular characterization of specific landraces of Japanese plum that have been adapted to extreme agroecosystems is a useful approach to localize candidate genes which are potentially interesting for breeding.
