“…Consequently, assessment of camel genetic diversity is important to help the development of breeding programs, which will facilitate improvements to camel productivity and identify genetically unique structures, furthering the ongoing conservation and utilization of these valuable animals. As morphological traits are highly affected by environmental factors (Shehzad et al 2009;Jugran et al 2013;Last et al 2014), morphological variation is not necessarily an accurate marker for genetic variation. Molecular markers are key resources for genetic investigations, as they complement morphological information and are informative at any developmental stage (Backes et al 2003).…”

Microsatellites or simple sequence repeats (SSRs) are among the genetic markers most widely utilized in research. This includes applications in numerous fields such as genetic conservation, paternity testing, and molecular breeding. Though ordered draft genome assemblies of camels have been announced, including for the Arabian camel, systemic analysis of camel SSRs is still limited. The identification and development of informative and robust molecular SSR markers are essential for marker assisted breeding programs and paternity testing. Here we searched and compared perfect SSRs with 1-6 bp nucleotide motifs to characterize microsatellites for draft genome sequences of the Camelidae. We analyzed and compared the occurrence, relative abundance, relative density, and guanine-cytosine (GC) content in four taxonomically different camelid species: Camelus dromedarius, C. bactrianus, C. ferus, and Vicugna pacos. A total of 546762, 544494, 547974, and 437815 SSRs were mined, respectively. Mononucleotide SSRs were the most frequent in the four genomes, followed in descending order by di-, tetra-, tri-, penta-, and hexanucleotide SSRs. GC content was highest in dinucleotide SSRs and lowest in mononucleotide SSRs. Our results provide further evidence that SSRs are more abundant in noncoding regions than in coding regions. Similar distributions of microsatellites were found in all four species, which indicates that the pattern of microsatellites is conserved in family Camelidae.

“…2013 ); however, such estimates do not reliably reflect the real genetic variation because most morphological characters are greatly influenced by environmental factors, the developmental stage of the plant and largely unknown genetic control of polygenic inheritance morphological traits ( Shehzad et al . 2009 ; Last et al . 2014 ).…”

Acer grosseri, an economically and ecologically important maple species, is mainly distributed in North China. Based on Sequence Related Amplified Polymorphism (SRAP) markers and morphological characters, A. grosseri shows rich genetic diversity. Less genetic differentiation occurred between than within natural populations. All studied populations of A. grosseri formed two main clusters. There was no significant correlation between genetic and geographical distances among populations. The biological characters, mating system, gene exchange, and selective pressure from environmental heterogeneity are the main factors affecting the genetic population structure of A. grosseri.

Mohebi Bijarpasi, M., Rostami Shahraji, T., Samizadeh Lahiji, H., 2019. Genetic variability and heritability of some morphological and physiological traits in Fagus orientalis Lipsky along an elevation gradient in Hyrcanian forests. Folia Oecologica, 46: 45-53.The purpose of the present study was to evaluate the genetic variability and heritability of some morphological and physiological traits in Fagus orientalis Lipsky along an elevation gradient in northern forests of Iran. Beech leaves were sampled from southern and northern crown parts of healthy mature trees along an elevation gradient comprising sites situated at 700 m, 1,200 m and 1,700 m above the sea level. Our statistical analysis showed that the investigated traits differed significantly between the populations. The results indicated the lowest and the highest coefficients of variation for the high (1,700 m) and middle elevation populations (1,200 m) for leaf length, petiole length, leaf area, specific leaf area, dry weight, specific dry weight, leaf index and petiole index traits. With increasing elevation, mean leaf width, distance from leaf base to the leaf maximum width, dry weight and petiole index increased. The plasticity of leaf length, specific leaf area, specific dry weight, petiole index and petiole length peaked at middle elevation, and with increasing elevation, the plasticity of these traits declined. The distance from leaf base to the leaf maximum width had the highest coefficient of genetic (75.5%) and phenotypic (75.5%) variation. The heritability results showed that there were differences in all traits, and that the highest heritability was recorded for the distance from the leaf base to the leaf maximum width (99.95 %). The results suggest that the studied beech populations responded to the environmental changes by changing their leaf traits in different ways at different altitudes.
