The nuclear factor Y (NF-Y) transcription factor (TF) family consists of three subfamilies NF-YA, NF-YB and NF-YC. Many studies have proven that NF-Y complex plays multiple essential roles in stress response in Arabidopsis and other plant species. However, little attention has been given to these genes in peanut. In this study, thirty-three AhNF-Y genes were identified in cultivated peanut and they were distributed on 16 chromosomes. A phylogenetic analysis of the NF-Y amino acid sequences indicated that the peanut NF-Y proteins were clustered in pairs at the end of the branches and showed high conservation with previous reported plant NF-Ys. Evolutionary history analysis showed that only segmental duplication contributed to expansion of this gene family. Analysis of the 1500-bp regulatory regions upstream the start codon showed that, except for AhNF-YB6, peanut NF-Ys contained at least one abiotic stress response element in their regulatory region. Expression patterns of peanut NF-Ys in 22 tissues and developmental stages were analyzed. A few NF-Ys showed universal expression patterns, while most NF-Ys showed specific expression patterns. Through RNA-seq and qRT-PCR analyses, expression of six AhNF-Y genes was induced under salt stress in leaves or roots. In addition, AhNF-YA4/8/11, NF-YB4 and NF-YC2/8 also responded to osmotic stress, ABA (abscisic acid) and salicylic acid (SA) treatment.

“…This study also indicated that H 2 S improved nutrient uptake efficiency and elevated ATPase and photosynthetic performance under Al stress (Dawood et al ). Pan et al () reported that exogenous NO alleviated Al‐induced programmed cell death in peanut root tips by inhibiting Al adsorption in cell walls, as well as lowering oxidative damage and ROS accumulation by enhancing the antioxidant defense system and reducing the peroxidation of membrane lipids. Thus, Al‐induced inhibition in root elongation was relieved by maintaining the extensibility of cell walls, decreasing pectin methylesterase (PME) activity and increasing xyloglucan endotransglucosylase (XET) activity and relative expression of the XET/hydrolase ( XTH32 ) gene.…”

Plants are exposed to a plethora of abiotic stresses such as drought, salinity, heavy metal and temperature stresses at different stages of their life cycle, from germination to seedling till the reproductive phase. As protective mechanisms, plants release signaling molecules that initiate a cascade of stress‐signaling events, leading either to programmed cell death or plant acclimation. Hydrogen sulfide (H2S) and nitric oxide (NO) are considered as new ‘gasotransmitter’ molecules that play key roles in regulating gene expression, posttranslational modification (PTM), as well as cross‐talk with other hormones. Although the exact role of NO in plants remains unclear and is species dependent, various studies have suggested a positive correlation between NO accumulation and environmental stress in plants. These molecules are also involved in a large array of stress responses and act synergistically or antagonistically as signaling components, depending on their respective concentration. This study provides a comprehensive update on the signaling interplay between H2S and NO in the regulation of various physiological processes under multiple abiotic stresses, modes of action and effects of exogenous application of these two molecules under drought, salt, heat and heavy metal stresses. However, the complete picture of the signaling cascades mediated by H2S and NO is still elusive. Recent researches indicate that during certain plant processes, such as stomatal closure, H2S could act upstream of NO signaling or downstream of NO in response to abiotic stresses by improving antioxidant activity in most plant species. In addition, PTMs of antioxidative pathways by these two molecules are also discussed.
