Drought stress memory in a germplasm of synthetic and common wheat: antioxidant system, physiological and morphological consequences

Abstract: Plants have evolved mechanisms of adaptation to fluctuations in their environmental conditions that have been given the term “stress memory”. Synthetic wheat offers new hope for breeders to restore useful genes lost during the genetic bottleneck. We aimed to test whether drought priming and seed priming could improve drought tolerance in a diverse germplasm of synthetic and common wheat under field conditions. In this research, 27 wheat genotypes (including 20 synthetics, 4 common local and 3 common exotic bre… Show more

“…Whether an enhanced response is indicative of a previous absence of priming in lowland rice remains to be demonstrated. Better response of sensitive varieties than their tolerant counterparts to stress priming has also been reported in wheat (Amini et al, 2023). The difference in the ability to be primed in contrasting rice genotypes could be attributed to 'memory loss' or lack of priming from stress (Charng et al, 2023).…”

“…Furthermore, drought tolerance and yield should be improved in parallel because of the long-standing instability of the security of wheat production, with farmers needing to generate agricultural products under drought stress [41]. In the past, many researchers have studied drought tolerance in wheat [29], but the improvement of this crop with respect to drought tolerance is limited for many reasons. Firstly, dramatic changes in plant physiological parameters caused by drought stress need to be measured and understood [42,43].…”

“…High yield and wide adaptation are principal targets of wheat breeding but are hindered by limited knowledge onof the genetic basis of the key agronomic traits, such as drought-stress tolerance [25]. Loss of advantageous alleles for drought stress tolerance due to preferential selection for yield potential may be a common phenomenon in wheat breeding [22,29] and it is not clear whether selection for yield potential facilitates or hampers genetic improvement for drought tolerance. As a result, it is imperative to identify the relationship between drought tolerance and yield potential in order to better understand the heritable co-variation between high yield potential and yield stability under drought in wheat.…”
