“…These determinations are represented as stress indicators because they act as a defense of plants. Besides, several compounds belonging to this class are associated with many benefits previously reported in the literature, including antioxidant [ 56 ], anti-inflammatory [ 57 ], anti-cancer [ 58 ] and anti-microbial [ 59 ] activities, mainly in association with other nutritional and medicinal properties [ 60 ].…”

Understanding drought response mechanisms in wheat and multi-trait selection

Wheat crop is very sensitive to osmotic stress conditions. As an abiotic stress, drought may exert a considerable effect on the levels of specialized metabolites in plants. These metabolites may exert beneficial biological activities in the prevention or treatment of disorders linked to oxidative stress in plants and humans. Furthermore, osmoprotector accumulation helps wheat to increase the maintenance of osmotic balance. Therefore, identifying wheat genotypes with better drought tolerance is extremely important. In this sense, this research aimed to understand agronomic, physiological and biochemical responses of spring wheat strains and cultivars to drought stress, under field conditions, and jointly select strains via multi-trait index. We evaluated agronomic, physiological and biochemical variables in 18 genotypes under field condition. The results demonstrated that all variables were affected by the drought. Most genotypes were significantly reduced in grain yield, except VI_14774, VI_14668, VI_9007 and TBIO_ATON. The variables related to photosynthesis were also affected. An increase above 800% was observed in proline contents in genotypes under drought. Sodium and potassium also increased, mainly for VI_131313 (Na), while VI_130758 and VI_14774 presented increased K. We evaluated the antioxidant potential of the different strains and the total content of phenolic compounds. The most drought-responsive genotypes were BRS_264, VI_14050 and VI_14426. Reduced grain yield and photosynthetic variables, and increased specialized metabolism compounds are due to plant defense mechanisms against drought conditions. Furthermore, variation in genotypes can be explained by the fact that each plant presents a different defense and tolerance mechanism, which may also occur between genotypes of the same species. Four strains were selected by the multivariate index: VI_14055, VI_14001, VI_14426 and VI_1466. Such results allow us to predict which genotype(s) performed best in semi-arid environments and under climatic fluctuations.

Mature embryos of einkorn (Triticum monococcum ssp. monococcum) and bread (Triticum aestivum) wheat were used for callus induction on media containing four (0, 1, 2 and 4 mg L− 1) different doses of 2,4-D and dicamba supplemented with under five (0, 6.2, 12.4, 24.8, and 37.2 mg L− 1) different boron stresses. The obtained callus was transferred to culture media with three (0, 0.5, and 2 mg L− 1) different BAP doses with five boron stresses for regeneration. The heaviest callus weight in einkorn wheat was in culture media with 1 mg L− 1 dicamba and 6.2 mg L− 1 (3.71 ± 0.13 g). Bread wheat had the heaviest callus weight on culture media with 4 mg L− 1 dicamba and 12.4 mg L− 1 (3.46 ± 0.40 g). Callus diameters were observed as the highest in culture media with 1 mg L− 1 and 12.4 mg L− 1 (1.10 ± 0.31) for einkorn and 4 mg L− 1 dicamba with 6.2 mg L− 1 boron (1.22 ± 0.27 cm) for bread wheat. Regeneration capacity was highest in control group with 6.2 mg L− 1 for both wheat genotypes (einkorn, 71.33% ± 11.78 and bread, 65.33% ± 10.80). The highest plantlet numbers were in only 2 mg L− 1 BAP (2.92 ± 0.88) for einkorn wheat and 0.5 mg L− 1 BAP supplemented with 6.2 mg L− 1 boron (3.71 ± 1.12) for bread wheat. This indirect regeneration protocol using mature embryos of einkorn and bread wheat under boron stresses may be useful for wheat breeding studies.

Mature embryos of einkorn ( Triticum monococcum ssp. monococcum ) and bread ( Triticum aestivum L.) wheat were used for callus induction on media containing four different doses (0, 1, 2 and 4 mg L −1 ) of 2,4-D and dicamba supplemented with five different boron concentrations (0, 6.2, 12.4, 24.8, and 37.2 mg L −1 ). The obtained callus was transferred to culture media with three (0, 0.5, and 2 mg L −1 ) different BAP doses with five boron concentrations for further regeneration. The maximum callus weight in einkorn wheat was in culture media with 1 mg L −1 dicamba and 6.2 mg L −1 (3.71 ± 0.13 g). Bread wheat had the maximum callus weight on culture media with 4 mg L −1 dicamba and 12.4 mg L −1 (3.46 ± 0.40 g).

This indirect regeneration protocol using mature embryos of einkorn and bread wheat under boron stresses expected to be useful for future wheat breeding studies.
