“…The topographic and aridity gradients that exists in the southeast Mediterranean region, ranging from relatively humid Mediterranean to arid desert environments over relatively short distances, mark this region as a prime live laboratory for studies aiming to understand evolutionary processes. Several studies conducted in this region demonstrated intra-specific phenological and morphological variation (Aronson et al, 1990;Petrů et al, 2006;Liancourt and Tielborger, 2009;Kigel et al, 2011;Waitz et al, 2021), emphasizing the possible role of abiotic selective factors on phenotypic and ecotypic divergence (Metz et al, 2020). Nevertheless, to date, no study in this region has yet attempted to explore the links between environmental heterogeneity, genome-wide variation, and phenotypic divergence.…”

Populations of Eruca sativa (Brassicaceae) derived from arid and Mediterranean habitats exhibit ecotypic differentiation. Here, pooled DNA sequencing was used to assess adaptive genome differentiation in the two ecotypes. Differentiated SNP loci were scanned with the empirical FST outlier method and by correlating allele frequencies with environmental parameters. Genetic diversity values were relatively higher in the pooled arid genome, whereas the pooled Mediterranean genome exhibited stronger directional selection, indicating the impact of climatic conditions on genetic diversity. GO enrichment analysis categorized the annotated differentiated loci according to biological processes, revealing a large set of candidate genes related to abiotic and biotic stress responses. Allelic variation was detected in regulatory elements and coding regions (synonymous and non-synonymous mutations) of genes belonging to different transcription factors and phytohormone signaling, suggesting adaptation to both abiotic and biotic conditions. Furthermore, SNP mutations were also found in genic regions belonging to the synthesis of secondary metabolites, including aliphatic glucosinolates and their hydrolyzed bioactive compounds, among others. The results of this eco-genomic study demonstrate the role of divergent abiotic and biotic selection factors in evolutionary processes leading to adaptive ecotypic differentiation.

“…Recent findings have shown that combined drought and heat stress during evocation may reduce silk and ovary growth, extend anthesis-silking interval in kernel number per plant in maize (Liu et al, 2020). Furthermore, there have been reports of the close association between flowering time and drought conditions in Sarcopoterium spinosum (Waitz et al, 2021). Studies have revealed that salt induced stress reduced flowering and fruit ripening, reduced fruit size and number per plant (Koffi et al, 2019).…”

This study was conducted to examine the effects of Salicylic acid (SA) and Potassium nitrate (KNO3) on plant height and flowering time of groundnut (Arachis hypogaea L.) under induced stresses of salinity, drought and combined salinity and drought. Three watering regimes namely; normal, moderate and severe were used. For salinity stress, 50 mM NaCl, 100 mM NaCl, 150 mM NaCl and combination of water and salinity regimes were used. 50 μm KNO3 and 50 μm SA were separately applied to plants under water, salinity and combined water and salinity stresses. The mean plant height at 100 mM salt concentration were 42.29 cm for KNO3, 42.27 cm for SA, compared with 40.98 cm for control (F = 2.73; P ≤ 0.008). In combined severe watering and 150 mM NaCl treatment, flowering time was 57 DAP (days after planting) compared to 34 DAP in control plants. When KNO3 and SA were applied to severe watering and 150 mM NaCl combined stress induced plants, flowering time was 51 DAP and 53 DAP for KNO3 and SA treated plants respectively. In conclusion, the exogenous application of plant growth regulators such as SA and KNO3 reduce impact of water stress on groundnut and effectively improve yield.
