Compared with Al (10 mmol/L) treatment alone, ALA (50 μmol/L) pretreatment for 24 h significantly enhanced cell viability by 28.40%, and hindered cell apoptosis by 12.35%, together with recovering redox state balance and alleviating mitochondrial damage. It was measured that ALA treatment upregulated Bcl-2 expression and down-regulated Bax level, accompanied with an expression decline of caspase-3 and caspase-9. Meanwhile, ALA pretreatment was proved to increase protein kinase A (PKA) expression and to promote phosphorylation of cAMP response element-binding protein (p-CREB), resulting in elevation on the level of brain-derived neurotrophic factor (BDNF).

Since, 30 TTC families with their 13 respective parents were evaluated during the summer season 2020 under two irrigation treatments. i.e., normal irrigation with 5952.38 m3 hm−2 of applied water, and water stress with 2976.19 m3 hm−2 of applied water.

Additive (D) and dominance (H) gene actions as well as epistatic and its two components of additive × additive, additive × dominance plus dominance × dominance were involved in the inheritance of all studied traits under both irrigation treatments and their combined analysis. The degree of dominance (H/D)0.5 verified the presence of partial dominance in most cases. The correlation coefficient between sums (additive) and differences (dominance) was non-significant, showing that dominant genes between lines were ambidirectional. The moderately water stress tolerant TTC families as the best selected families were found in families 22, 25, 10, 12, and 15.

Additionally, under abiotic stresses including hot temperature, low temperature, drought and salt stresses, the sugar allocation among leaf, stem and roots was tested. The expressional changes of RcSUCs in leaf, stem and root tissues were associated with sugar transportation and allocation. Taken together, the differential expression of RcSUCs among tissues responsing to abiotic stress suggested functional differences in sucrose transport and redistribution in different tissues.
