“…In addition, these MQTLs included 16-79 initial QTLs derived from 11 to 35 interval mapping studies. For instance, MQTL1D.4 was based on 24 QTLs derived from 11 different interval mapping studies which included 8 major QTLs (> 15% PVE) derived from four mapping studies [90][91][92][93] ; MQTL2D.5 was based on 25 QTLs identified in 12 mapping studies which also included 6 major QTLs derived from 3 mapping studies 91,94,95 ; MQTL3A.1 was based on 70 QTLs derived from 35 mapping studies which included 12 major QTLs derived from 7 studies 90,91,96-100 , MQTL4A.2 was based on maximum of 79 QTLs derived 32 studies, although none of the QTLs had PVE ≥ 15%. Therefore, these are believed to be the most stable and consistent MAST-MQTLs across all genetic backgrounds Vol:.…”

In wheat, a meta-analysis was performed using previously identified QTLs associated with drought stress (DS), heat stress (HS), salinity stress (SS), water-logging stress (WS), pre-harvest sprouting (PHS), and aluminium stress (AS) which predicted a total of 134 meta-QTLs (MQTLs) that involved at least 28 consistent and stable MQTLs conferring tolerance to five or all six abiotic stresses under study. Seventy-six MQTLs out of the 132 physically anchored MQTLs were also verified with genome-wide association studies. Around 43% of MQTLs had genetic and physical confidence intervals of less than 1 cM and 5 Mb, respectively. Consequently, 539 genes were identified in some selected MQTLs providing tolerance to 5 or all 6 abiotic stresses. Comparative analysis of genes underlying MQTLs with four RNA-seq based transcriptomic datasets unravelled a total of 189 differentially expressed genes which also included at least 11 most promising candidate genes common among different datasets. The promoter analysis showed that the promoters of these genes include many stress responsiveness cis-regulatory elements, such as ARE, MBS, TC-rich repeats, As-1 element, STRE, LTR, WRE3, and WUN-motif among others. Further, some MQTLs also overlapped with as many as 34 known abiotic stress tolerance genes. In addition, numerous ortho-MQTLs among the wheat, maize, and rice genomes were discovered. These findings could help with fine mapping and gene cloning, as well as marker-assisted breeding for multiple abiotic stress tolerances in wheat.

“…Leaf photosynthesis is a component of canopy photosynthesis, which accounts for most variations in biomass production and grain yield (Yoshida and Horie 2009). Leaf chlorophyll content can be used as a photosynthetic capacity index, which can be an effective strategy to increase yield under different environmental constraints (Farokhzadeh et al 2019). In the Zaharieva et al (2001) study, SPAD was significantly and positively correlated with biomass and grain weight per wheat plant.…”

“…), Al demonstrates toxic characteristics and creates disadvantage to plants even at micromolar (lM) concentrations (Garcia-Oliveira et al 2018). To cope with Al stress, plants demonstrate different physiological, morphological, and biochemical changes (Farokhzadeh et al 2019). Aluminum tolerant genotypes have better water and nutrients absorption, so that it enhances plant growth and subsequently, the yield and tolerance to environmental stresses like drought stress improve (Lynch and Wojciechowski 2015;Garcia-Oliveira et al 2018).…”

“…Still, the difference in root architecture between cultivars related to aluminum tolerance is not easy to examine. On the contrary, evaluation of the physiological situation of the aerial portion of the plant is easier, proving essential details on the capability of the plant to have access to nutrient and water resources (Farokhzadeh et al 2019).…”

Finding the suitable traits that mediate grain yield under stress condition represent an important challenge to plant breeders in order to improve production. Meaningful progress in computational analysis enables us to solve this challenge in a more efficient way. In this frame of study, our objective was to determine the most important traits associated with wheat yield improvement under aluminum stress using attribute weighting as well as supervised algorithms. To meet this goal, we studied, under normal and stress conditions, 167 bread wheat recombinant inbred lines. The lines were obtained from a cross of two semidwarf spring wheat varieties featured with considerable yield potential; Seri M82 and Babax. A total of 50 different traits including phenological, morphological, agronomic, physiological and biochemical traits were recorded. Ranking traits by attribute weighting algorithms indicated that among the 50 traits, five and eight traits were respectively the most probable candidates under normal and stress conditions, as highlighted by at least six weighting algorithms. According to the performance of decision tree algorithms employed, traits that were pinpointed traits by attribute weighting can be utilized to efficiently discriminate high-, medium-, and lowyield lines with up to 74.92% and 81.47% under normal and stress conditions, respectively. Moreover, valuable basis can be extrapolated from our decision tree models to guide plant breeders for selecting high Sara Farokhzadeh and Zahra Zinati equally contributed to this study.

“…Numerous reports have revealed mechanisms such as Al exclusion from the roots and evacuation to the vacuole in response to Al toxicity in rice [ 4 , 5 ], wheat, barley, maize [ 6 , 7 ], and rye and Arabidopsis [ 8 ]. QTLs related to Al tolerance have been identified and used to develop Al-tolerant crops such as maize [ 9 , 10 ], Arabidopsis [ 11 ], wheat [ 12 ], and rice [ 13 ] using breeding or molecular approaches. Genes such as MATE, ALMT, ASR, and ABC transporters have been implicated in some plants for resistance to Al [ 14 ], for instance, Al-responsive genes in potato [ 15 ], rice [ 16 ], wheat [ 17 ], sorghum [ 18 ], rye [ 19 ], and sugarcane [ 20 ].…”

Peanut is among the most important oil crops in the world. In the southern part of China, peanut is highly produced; however, the arable land is acidic. In acidic soils, aluminum (Al) inhibits plant growth and development by changing the properties of the cell wall and causing the disorder of the intracellular metabolic process. Circadian rhythm is an internal mechanism that occurs about every 24 h and enables plants to maintain internal biological processes with a daily cycle. To investigate the effect of photoperiod and Al stress on the Al-induced programmed cell death (PCD), two peanut varieties were treated with 100 μM AlCl3 under three photoperiodic conditions (8/16, SD; 12/12, ND; 16/8 h, LD). The results show that Al toxicity was higher in ZH2 than in 99-1507 and higher under LD than under SD. Root length decreased by 30, 37.5, and 50% in ZH2 and decreased by 26.08, 34.78, and 47.82% in 99-1507 under SD, ND, and LD, respectively, under Al stress. Photoperiod and Al induced cell death and ROS production. MDA content, PME activity, and LOX activity increased under SD, ND, and LD, respectively, under Al stress both in ZH2 and 99-1507. APX, SOD, CAT, and POD activities were higher under SD, ND, and LD, respectively. Al stress increased the level of AhLHY expression under SD and ND but decreased it under LD in both ZH2 and 99-1507. Contrastingly, AhSTS expression levels increased exponentially and were higher under SD, LD, and ND, respectively, under Al stress. Our results will be a useful platform to research PCD induced by Al and gain new insights into the genetic manipulation of the circadian clock for plant stress response.
