“…It plays a fundamental role in the evolutionary trajectory of species and thus affects all levels of biodiversity (Crutsinger et al, 2006, 2007; Hughes et al, 2008; Stange et al, 2021). This has direct implications for species utilization in agriculture (Kannenberg & Falk, 1995; Hoisington et al, 1999), pharmacology (Elisabetsky & Costa-Campos, 1996; Barata et al, 2016) or bioenergy (Jaradat; 2010; Kiru & Nasenko, 2010) as well as on ecosystems’ stability and scope for recovery (Reusch et al, 2005; Reynolds et al, 2012). Therefore, understanding how species genetic diversity is distributed is crucial.…”

Genetic diversity a major determinant for the capacity of species to persist and adapt to their environments. Unraveling the factors affecting genetic differentiation is crucial to understand how genetic diversity is shaped and species may react to changing environments. We employed genotyping by sequencing to test the influence of climate, space, latitude, altitude and land cover on genetic differentiation in a collection of 81 wild pea samples (Pisum sativum ssp. elatius) from across its distribution range from western Europe to central Asia. We also attempted to elucidate the species recent evolutionary history and its effect on the current distribution of genetic diversity. Association of single SNPs with climate variables were analyses to test for signatures of local adaptation. Genetic variation was geographically structured into six distinct genetic cluster. Two of which were associated with a taxonomic group (Pisum sativum ssp. humile) that according to some researchers does not qualify for a sub-species rank due to its alleged lack of genetic distinctness from other conspecific groups. The effect of the tested factors influencing genetic differentiation were rather variable among genetic clusters. The climate predictors were most important in all clusters. Land use was more important in clusters from areas strongly influenced by human land use, especially by agriculture. We found a statistically significant association of 3,623 SNPs (2.4 % of all SNPs) with one of the environmental predictors. Most of them were correlated with latitude followed by temperature, precipitation and altitude. Estimation of SNP effects of the candidates resulted in a missense to silent ratio of 0.45, suggesting many of the observed candidates SNPs may alter the encoded amino acid sequence. Wild peas went through a genetic bottleneck during the last glacial period followed by population recovery. Probably associated with this population recovery, we detected a range expansion, which may have led to an eastward range expansion of the European cluster to Turkey and thereof southwards and eastwards. Overall, the interplay of several environmental factors and the recent evolutionary history affected the distribution of genetic diversity in wild peas where each subpopulations were differently affected by those factors and processes.

“…Such mechanisms include the absorption, transport, and homeostasis of ions, osmotic regulation, and salt removal from leaves [ 37 , 38 ]. Although the cultivation of these plants is not an easy task, the germplasm of halophyte plants is considered a valuable source for providing genes resistant to environmental conditions, for the implementation of plant-breeding programs [ 63 ]. In the current study, the expression profiles of AlCBLs and AlCIPKs were investigated under salt stresses in the roots and leaves of A. littoralis .…”

Plants have acquired sets of highly regulated and complex signaling pathways to respond to unfavorable environmental conditions during evolution. Calcium signaling, as a vital mechanism, enables plants to respond to external stimuli, including abiotic and biotic stresses, and coordinate the basic processes of growth and development. In the present study, two calcium sensor families, CBL and CIPK, were investigated in a halophyte plant, Aeluropus littoralis, with a comprehensive analysis. Here, six AlCBL genes, and twenty AlCIPK genes were studied. The analysis of the gene structure and conserved motifs, as well as physicochemical properties, showed that these genes are highly conserved during evolution. The expression levels of AlCBL genes and AlCIPK genes were evaluated under salt stress in leaf and root tissue. Based on the real-time RT-PCR results, the AlCIPK gene family had a higher variation in mRNA abundance than the AlCBL gene family. AlCIPK genes were found to have a higher abundance in leaves than in roots. The results suggest that the correlation between AlCBL genes and AlCIPK is tissue-specific, and different correlations can be expected in leaves and roots. Based on these correlations, AlCIPK3.1–AlCBL4.1 and AlCIPK1.2–AlCBL4.4 can be co-expressed in the root tissue, while AlCBL10 has the potential to be co-expressed with AlCIPK5, AlCIPK26, and AlCIPK12.3 in the leaf tissue. Our findings reveal valuable information on the structure and function of calcium sensor families in A. littoralis, a halophyte plant, that can be used in future research on the biological function of CBLs and CIPKs on salt stress resistance.

“…In addition, they provide organic matter which enhance the soil fertility, nutrients retention, structure, and stability of the soil, diminishing soil loss caused through erosion and runoffs [ 3 ]. Moreover, their high photosynthetic capacity (ensuring greater CO 2 fixation), utmost yield potential, significant sugars, lignin and cellulose reservoirs, and low environmental impact (compared to other annual crops), make perennial grasses an attractive source for the production of biofuels [ 4 , 5 ]. In Europe, about 20 perennial species have been studied for biomass production, and among them, three rhizomatous grasses ( Panicum virgatum L., Miscanthus x giganteus and Arundo donax L.) have been chosen for larger research programs [ 2 ].…”
