“…Notably, the increased accumulation of H 2 O 2 causes lipid peroxidation and membrane damage ( Banerjee and Roychoudhury, 2018 ; Yadav et al, 2018 ). Heat stress-mediated genetic variations have been investigated in several cereal crops, including wheat, barley, rice, and maize ( Kumari et al, 2009 ; Khajuria et al, 2016 ; Swapna and Shylaraj, 2017 ). Balanced redox reaction system activation via enzymatic antioxidants, such as superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase, and non-enzymatic antioxidants, such as NADH; NADPH; ascorbic acid, glutathione, and secondary metabolites play a crucial role in heat stress tolerance ( Wahid et al, 2007 ; Foyer and Shigeoka, 2011 ).…”

Graphical AbstractThis review summarized heat stress-mediated morphological and physiological changes in maize and elucidated the molecular mechanisms responsible for maize response to heat stress. Furthermore, plausible approaches to dissecting the regulatory network associated with heat stress response and improving maize adaptation to global warming have been discussed. This figure was made using BioRender.

“…In this context, Awan et al (2015) reported that grain yield was closely linked to relative water content, cell membrane stability and specific flag leaf area. The increased solute leakage, marker of decreased cell membrane thermostability, is used as a measure of heat-stress tolerance (Wahid et al, 2007;Khajuria et al, 2016). The present investigation aimed to assess the variability, stability and relationships of grain yield with physio-morphological traits in a set of durum wheat (Triticum durum Desf.)…”

<p>The present study aimed to investigate the extent of variability and relationships between grain yield and morpho-physiological durum wheat traits. Sufficient variability was observed for most characters. Based on stress indices, either widely or specifically, adapted lines were identified. Path analysis pointed out to above ground biomass, harvest index, spike fertility and spike number as yield determinants, suggesting that these traits are of interest in the breeding program. The measured traits were classified within 6 principal components accounting for 79.45 % of the total variation. Breeding lines dispersed along first principal component exhibited substantial differences in performance and stress tolerance abilities. Cluster C3 lines were high yielding and stress tolerant. From this cluster, lines L24 and L14 were scored as the best for 7 and 5 traits out of 17 characters, respectively. Both lines are proposed for release and as parents in crosses to take advantage of their desirable characteristics. The results indicated that physiological traits were unrelated to each other and to morphological traits making difficult the concomitant selection for yield and stress tolerance driven by these traits. Complexes crosses, between parents carefully chosen for these specific characteristics, are necessary to enhance favorable genetic linkage and to generate new basic segregating populations with high genetic variability for these traits.</p>

“…The threshold temperature considered as the value of daily mean temperature, at which a detectable reduction in growth begins, is 26℃ for wheat at post anthesis stage [5]. In wheat, terminal heat stress with ambient temperature > 30˚C, during reproductive development stage has been found to decrease productivity [6]. Accompanied with rising mean temperature as a result of global warming, high temperature at the time of grain filling affects grain production in many environments [7].…”
