Abstract
The genus Ganoderma belongs to Polyporales, well-known for its medicinal properties and as a plant pathogen. The aim of this study was to identify the genetic variation between populations of two Ganoderma lucidum Karst. complex isolates using RAPD. For this purpose, four populations of G. resinaceum Boud. and eight populations of G. lucidum collected and purified during 2011-2012, were studied for the first time in Iran. Ten random primers were used for RAPD reaction. The result for RAPD-PCR studies of G. lucidum complex showed a wide range of diversity, as scores of 61.48 and 40.16 were estimated for the inter-specific diversity of G. lucidum and G. resinaceum, respectively. Cluster analysis confirmed the separation of two species populations in different clusters. In the analysis of genetic structure, two probable groups (K = 2) were identified in the studied germplasm which was also confirmed by the results of bar plot.

Abstract
This study aimed to investigate the polymorphism of matrix metalloproteinase -3 (MMP-3) gene and its expression in the serum of infertile female patients received in vitro fertilization and embryo transfer (IVF-ET). To do so, 100 women with unsuccessful IVF-ET (IVF–) and 100 women with successful IVF-ET procedure and clinical pregnancy (IVF+) were included. Genetic polymorphism and serum concentration of MMP3 were investigated by ARMS-PCR and ELISA, respectively. The results showed no significant association between MMP-3 gene polymorphism and IVF-ET outcome among the two groups studied. However, a significant decrease in the concentration of MMP-3 serum in the IVF– group was observed in comparison with the IVF+ group (P=0.000002). Moreover, we showed that the serum MMP-3 levels in CC, AC and AA genotypes in the IVF– group were 33, 65.33 and 86 ng/ml, respectively. In conclusion, while there is no significant difference between MMP-3 promoter polymorphism and IVF-ET outcome between the IVF+ and IVF- groups, a significant decrease in MMP-3 serum levels in IVF- group was seen as compared with the IVF+ group. It could be also suggested that the CC genotype is associated with a decreased level of MMP-3 serum concentration and may be associated with IVF-ET failure.

Abstract
Chickpea is one of the most important plants of the legume family and is very important in the diet. In order to investigate the genetic diversity of chickpea, an experiment was conducted with 18 chickpea genotypes in the form of a completely to investigate the genetic diversity of chickpea, an experiment was conducted with 18 chickpea genotypes in the form of a completely randomized block design. After acclimatization of plants to cold, freezing treatment was applied at temperatures of -6, -8 and -10 and their 50% lethality temperature (LT50) was determined by probit transformation. Before and after the habituation stage, a leaf sample was taken and the relative content of leaf water, photosynthetic pigments, proline, soluble sugar, protein percentage, catalase, peroxidase, polyphenol oxidase and greenness index were measured. Genotype number 5 with the lowest LT50 (-8.86) and the highest survival percentage (80%) was the most resistant genotype and genotype 10 with the highest LT50 (-3.57) and the lowest survival percentage along with genotype 15 were recognized as the most sensitive genotypes. In order to evaluate genetic diversity, DNA extraction was utilized and 21 different ISSR primers were used in the investigation. The results showed the presence of polymorphism among the cultivars studied. A total of 101 clear bands were produced, of which 94 were polymorphic bands. Polymorphic information content (PIC) was in the range of 0.332 (initiator 7) to 0.049 (initiator 16). The amount of gene diversity was between 0.126 and 0.977 changes. Cluster analysis of genotypes was done using Jaccard similarity coefficient and UPGMA method
