“…However, the introgression of genes of tolerance identified in new sources of variation into commercial varieties may took several years (Fita et al, 2015). As an alternative, the direct use of rootstocks may offer a short-term solution, which, apart from increasing the vigour and productivity of the variety, may also provide a satisfactory adaptation to abiotic stresses (Kumar et al, 2017;Razi and Muneer, 2023). To this regard, materials domesticated in regions affected by hot and dry weathers or saline soils are good candidates to be tried.…”

Climate change in the Mediterranean areas is increasing problems on droughts, water availability and salinization of irrigation water. These are probably some of the most limiting factors on farming, especially in vegetables production. Capsicum peppers, one the most valuable vegetables in Spain, are quite sensitive to water deficit and particularly to salinity. The use of rootstocks tolerant to these abiotic stresses could be explored as a short/mid-term solution. In this work, we evaluated the ability as rootstocks of several accessions, together commercial F1 ‘Robusto’ and ‘Oscos’, with the cultivar ‘Herminio’ as scion, under control, drought (30% decrease irrigation) and salinity (5.8 dS m-1) in Campo de Cartagena area (Murcia, Spain). Yield and fruit weight, and water content, ascorbic acid content (AAC) and total phenolics (TP) at the unripe and fully ripe commercial stages were evaluated. Under control conditions, our rootstocks did not provide extra vigour and yield as none showed higher performance than the non-grafted ‘Herminio’ in yield (10 kg m-2) and fruit weight (215 g). However, drought and salinity conditions revealed that some accessions might be useful as rootstocks, providing higher yields and/or fruit size than ‘Herminio’, particularly yield under drought, i.e. 5-7 kg m-2 while ‘Herminio’ only achieved 4 kg m-2, and fruit weight in both stress conditions (i.e. 190-223 g vs 173 g under drought, 187-209 g vs 158 g under salinity). On average, drought increased the levels of antioxidants at both ripening stages, while salinity decreased them, specially AAC. Also, remarkable rootstock × treatment interactions, particularly in phenolics, enabled identifying several rootstocks providing high levels of antioxidants at both ripening stages and under both abiotic stresses, improving those from non-grafted ‘Herminio’.

The cereal plant barley (Hordeum vulgare) has high nutritional content and special characteristics that allow it to withstand adverse weather conditions. The peduncle’s developmental properties under dry (drought and heat) conditions make it an ideal attribute for studying its function in tolerance and adaption processes. Thus, we intend to investigate the natural phenotypic and genetic variation of the peduncle length, as well as the genetic reasons underpinning its growth in dry (drought and heat) environments. Under natural drought and heat, the examined characteristic showed a large range of natural variation, showing its involvement in adaptation to such circumstances. A genome-wide association study (GWAS) was carried out to evaluate the relationship between 127,022 single nucleotide polymorphisms (SNPs) and peduncle length at maturity in 184 barley accessions from throughout the world. The genomic research suggest the possibility of 86 marker-trait associations (p-value: > FDR) in various genomic areas, five of which are physically situated on chromosome 3H. The presence of 23 candidate genes was discovered after predicting candidate genes underlying significant relationships. The RNA-sequencing expression profile of candidate genes revealed that the gene HORVU.MOREX.r2.3HG0216310.1, which was identified as a Polynucleotidyl transferase ribonuclease H-like superfamily protein, had the greatest level of expression, indicating its participation in peduncle development under these conditions. Quantifying the current natural variation in peduncles under dry environmental circumstances and identifying the genomic areas linked with the features will serve as the foundation for future genetic research to better understand its function in stress tolerance.
