“…Grafting is a special type of asexual plant propagation where a section of a plant (scion) is joined to another plant (rootstock), allowing it to grow as a single plant sharing a unified vascular system [ 104 ]. In order to combine two groups of desired characteristics, usually both scion and rootstock sources are from different plant varieties.…”

The major challenges that agriculture is facing in the twenty-first century are increasing droughts, water scarcity, flooding, poorer soils, and extreme temperatures due to climate change. However, most crops are not tolerant to extreme climatic environments. The aim in the near future, in a world with hunger and an increasing population, is to breed and/or engineer crops to tolerate abiotic stress with a higher yield. Some crop varieties display a certain degree of tolerance, which has been exploited by plant breeders to develop varieties that thrive under stress conditions. Moreover, a long list of genes involved in abiotic stress tolerance have been identified and characterized by molecular techniques and overexpressed individually in plant transformation experiments. Nevertheless, stress tolerance phenotypes are polygenetic traits, which current genomic tools are dissecting to exploit their use by accelerating genetic introgression using molecular markers or site-directed mutagenesis such as CRISPR-Cas9. In this review, we describe plant mechanisms to sense and tolerate adverse climate conditions and examine and discuss classic and new molecular tools to select and improve abiotic stress tolerance in major crops.

“…Important fruit crops are frequently propagated by grafting methods, such as apples, avocados, peaches, citrus, apricots, cherries, plums, and almonds [ 104 , 106 ], and also conifers [ 107 ], among others. Only a few decades ago, vegetable crops were incorporated into the grafting practice [ 101 , 103 , 108 , 109 ].…”

Background The use of vegetable grafting has proven to be effective not only in providing stress resistance but also improving fruit yields. There have been no studies on grafted vegetables' effects on the vascular systems, specifically xylem vessels. This study tested the effects of two groups of rootstocks, Solanum spp., and Solanum lycopersicum , on seedling growth, anatomical parameters, and further plant growth and yield of eggplant cv. Madonna. The experiment was arranged in a completely randomized design with four replications and five plants in each replication. Results The results showed that seedling growth parameters including height, and stem diameter were significantly different between grafted and non-grafted eggplant plants. In terms of roots, cv. Optifort rootstock had the longest roots, while Solanum spp. rootstocks had the largest root volume. The radial widths of rootstock collenchyma and phloem were significantly greater in SG-self-grafted than in SR-self-rooted and in other rootstocks. Rootstock xylem area was higher in Solanum spp. than in self-rooted seedlings and cv. Emperador rootstock. Correlation analysis showed that rootstock anatomical traits, including xylem width and cortex parenchyma cell number, had significant positive correlations with yield (r = 0.40 and r = 0.58, respectively). Rootstocks such as ST ( Solanum torvum ) and A ( Solanum integrifolium) which had wider xylem and more cortex cells, exhibited higher yields. Conclusion Rootstocks with larger xylem widths and higher cortex cell numbers, such as ST and A, promoted greater yield in grafted eggplant. These results emphasize the importance of selecting rootstock-scion combinations with favourable anatomical traits for optimal productivity.
