“…Most genetic variation occurred within a population or among clumps (AMOVA , Table 3); the highest genetic differences were found between clumps, and the value of Φ PT indicated high to moderate genetic differentiation between the studied populations. This pattern is dissimilar to other clonal species with low values of differentiation among populations as in Potamogeton pectinatus in which Abbasi, Afsharzadeh, and Saeidi (2017) found values of Φ PT = 0.11 and the highest genetic variation located within populations (89%).…”

The diverse offspring of clonal species differ in their dispersability, influencing genotypic diversity and clonal structure. Here, we determined dispersal patterns and their impact on genetic structure in Opuntia microdasys, a self‐incompatible cactus with three dispersal units (one sexual and two clonal). We analyzed dispersal, using experiments at three populations, and assessed multilocus genotypes (ISSR markers) of all individuals in 10 clumps per population with known reproductive origin (sexual or clonal). Genotype of all samples, population structure, and migration between clumps and populations were assessed with GenAlEx and GenoDive, assuming higher genotypic diversity and migration when sexual reproduction is more frequent. We determined the most likely number of genetic clusters with STRUCTURE and geneland. Dispersal differed among populations; primary dispersal occurred at short distances and was farthest on steep slopes, and dispersal distance increased after secondary dispersal. Clumps had 116 different multilocus genotypes in three spatially explicit genetic clusters. We detected genetic structure at small scale, genotypic diversity among clumps varied between populations; diversity decreased while clonal dominance increased, and the most variation occurred among clumps. Genetic structure was moderate, suggesting gene flow by seed dispersal allows slight differentiation among population at large scales. Genetic diversity within clumps was the lowest because dispersal of clonal propagules was limited and caused genotypic dominance at local scale. However, the combined dispersal pattern of sexual and clonal dispersal units is fine‐tuned by environmental factors, generating a range of genetic diversity among clusters and populations. This pattern suggests that genetic structure of clonal plants is more dynamic than thought, and dispersal of different types of offspring affects genetic structure at many scales.

“…Potamogeton pectinatus L.) is a common species of several eutrophic to hyper-eutrophic fresh to brackish waters worldwide [9][10][11]. Because the plant is food for waterfowl [12], it spreads over long distances [13] and in different environments, where it survives through acclimatization by means of plastic phenotypic responses [1,14,15] and genetic differentiation [16,17].…”

Stuckenia pectinata, a submerged macrophyte of eutrophic to hyper-eutrophic fresh to brackish waters, faces management and climatic-forced increment of salinity and irradiance in Vistonis Lake (Greece) that may endanger its existence and the ecosystem functioning. A pre-acclimated clone under low irradiance and salinity conditions was treated to understand the effects of high salinity and irradiance on a suite of subcellular (chlorophyll a fluorescence kinetics and JIP-test, and chlorophyll content) to organismal (relative growth rate—RGR) physiological parameters. The responses to high irradiance indicated the plant’s great photo-acclimation potential to regulate the number and size of the reaction centers and the photosynthetic electron transport chain by dissipation of the excess energy to heat. A statistically significant interaction (p < 0.01) of salinity and irradiance on Chl a, b content indicated acclimation potential through adjusting the Chl a, b contents. However, no significant (p > 0.05) difference was observed on Chl a/b ratio and the RGR, indicating the species’ potential to become acclimatized by reallocating resources to compensate for growth. Thus, the regulation of photosynthetic pigment content and photosystem II performance consisted of the primary growth strategy to present and future high salinity and irradiance stressful conditions due to eutrophication management and the ongoing climatic changes.

The aim of this study was to investigate the genetic variations of Iranian Silybum marianum accessions using inter simple sequence repeat (ISSR) markers. Twenty-nine accessions from various Iran regions and a sample from Hungary were selected and evaluated by 19 ISSR primers. A clear banding pattern was produced by 9 primers and a total of 85 repeatable polymorphic bands were detected. ISSR7 and ISSR8 primers identified the most Polymorphic Information Content (PIC) with 100% among primers. In the tested accessions, polymorphism information content (0.45), polymorphic percentage (83 %), and Shannon?s information index (0.53) assessed a high level of genetic variation. Based on Jaccards distances, cluster analysis molecular traits with unweighted pair group method with arithmetic mean (UPGMA) method were taken into consideration, and accessions were grouped into nine clusters and confirmed by principal coordinate analysis. Four clusters were identified by a Bayesian structure analysis, and 12 individuals were maintained inside the admixed clusters. According to the findings, ISSR marker system can be considered as a powerful tool for detection of genetic diversity of accessions in S. marianum. The results indicate existence of a high variation among Iranian S. marianum accessions to start the breeding programs.
