Unraveling the role of tomato Bcl-2-associated athanogene (BAG) proteins during abiotic stress response and fruit ripening

AbstractB-cell lymphoma2 (Bcl-2)-associated athanogene (BAG) family proteins are evolutionary conserved across all eukaryotes. These proteins interact with HSP70/HSC70 and function as co-chaperones during stress response and developmental pathways. Compared to the animal counterpart, the BAG proteins in plants are much less studied and primarily Arabidopsis BAG proteins have been identified and characterized for their role in programmed cell death, homeostasis, growth and development, abiotic and biotic stress response. Here, we have identified BAG protein family (SlBAGs) in tomato, an economically important and a model fruit crop using genome-wide scanning. We have performed phylogenetic analysis, genes architecture assessment, chromosomal location and in silico promoter analysis. Our data suggest that SlBAGs show differential tissue specific expression pattern during plant development particularly fruit development and ripening. Furthermore, we reported that expression of SlBAGs is modulated during abiotic stresses and is regulated by stress hormones ABA and ethylene. In planta subcellular localization reveals their diverse subcellular localization, and many members are localized in nucleus and cytoplasm. Like previous reports, our protein–protein interaction network and yeast two-hybrid analysis uncover that SlBAGs interact with HSP70. The current study provides insights into role of SlBAGs in plant development particualry fruit ripening and abiotic stress response.

Transcriptional Changes

AbstractYeast Snf1 (Sucrose non-fermenting1), mammalian AMPK (5′ AMP-activated protein kinase) and plant SnRK1 (Snf1-Related Kinase1) are conserved heterotrimeric kinase complexes that re-establish energy homeostasis following stress. The hormone abscisic acid (ABA) plays a crucial role in plant stress response. Activation of SnRK1 or ABA signaling results in overlapping transcriptional changes, suggesting these stress pathways share common targets. To investigate how SnRK1 and ABA interact during stress response in Arabidopsis thaliana, we screened the SnRK1 complex by yeast two-hybrid against a library of proteins encoded by 258 ABA-regulated genes. Here, we identify 125 SnRK1- interacting proteins (SnIPs). Network analysis indicates that a subset of SnIPs form signaling modules in response to abiotic stress. Functional studies show the involvement of SnRK1 and select SnIPs in abiotic stress responses. This targeted study uncovers the largest set of SnRK1 interactors, which can be used to further characterize SnRK1 role in plant survival under stress.

Specific Expression

AbstractThe 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.
