“…Three ethylene receptors (two ETRs and one ERS) were also reported in the “Kent” variety of which two ETR homologs remained unchanged whereas one ERS showed down-regulation5. In a recent report, different versions of the mango ethylene receptor MiERS1 from Hôi’ cultivar were identified by Winterhagen et al 24. They suggested that in addition to MiERS1 , two short versions of this receptor ( MiERS1m , MiERS1s ) are also present in mango.…”

Ripening in mango is under a complex control of ethylene. In an effort to understand the complex spatio-temporal control of ripening we have made use of a popular N. Indian variety “Dashehari” This variety ripens from the stone inside towards the peel outside and forms jelly in the pulp in ripe fruits. Through a combination of 454 and Illumina sequencing, a transcriptomic analysis of gene expression from unripe and midripe stages have been performed in triplicates. Overall 74,312 unique transcripts with ≥1 FPKM were obtained. The transcripts related to 127 pathways were identified in “Dashehari” mango transcriptome by the KEGG analysis. These pathways ranged from detoxification, ethylene biosynthesis, carbon metabolism and aromatic amino acid degradation. The transcriptome study reveals differences not only in expression of softening associated genes but also those that govern ethylene biosynthesis and other nutritional characteristics. This study could help to develop ripening related markers for selective breeding to reduce the problems of excess jelly formation during softening in the “Dashehari” variety.

“…Subfamily 1 contains ETR1 and ERS1 , and subfamily 2 contains ETR2 , ERS2 , and EIN4 . ETR1 , ETR2 , and ERS2 are important fruit ethylene receptor genes ( Winterhagen et al, 2016 ). It has been suggested that 1-MCP treatment can effectively prevent ethylene-induced maturation and senescence by regulating ethylene biosynthesis and the expression of ethylene receptor genes ( MiETR1 and MiERS1 ) ( Li et al, 2020 ).…”

“…Ethylene is perceived through its binding to its receptors, which act as negative regulators [38][39][40]. As mentioned above, the expression profiles of MiERS1 and MiETR1 ethylene receptors were previously characterized during mango fruitlet drop [31][32][33]. Here, we expanded these studies to examine the effect of ethephon treatment on the expression profiles of additional ethylene signaling-related genes in fruitlet AZs.…”

“…Further examination of the expression patterns of two mango ethylene receptor genes, MiETR1 and MiERS1, showed that mango fruitlet shedding is associated with strong upregulation of MiERS1 in fruitlet AZs [31], and with an increase in the MiERS1/MiETR1 ratio in the AZs of "about to abscise" fruitlets [32]. These studies were later extended to monitor levels of expression of novel MiERS1 and MiETR1 isoforms present in the 'Hoi' poly-embryonic mango cultivar [33]. With respect to IAA function, it was shown that mango fruitlet drop is associated with a reduction in the polar IAA transport capacity through the fruitlet pedicel, and with a reduction in sucrose accumulation in the fruitlet pericarp tissue [32].…”

In mango (Mangifera indica L.), fruitlet abscission limits productivity. The INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) peptide acts as a key component controlling abscission events in Arabidopsis. IDA-like peptides may assume similar roles in fruit trees. In this study, we isolated two mango IDA-like encoding-genes, MiIDA1 and MiIDA2. We used mango fruitlet-bearing explants and fruitlet-bearing trees, in which fruitlets abscission was induced using ethephon. We monitored the expression profiles of the two MiIDA-like genes in control and treated fruitlet abscission zones (AZs). In both systems, qRT-PCR showed that, within 24 h, both MiIDA-like genes were induced by ethephon, and that changes in their expression profiles were associated with upregulation of different ethylene signaling-related and cell-wall modifying genes. Furthermore, ectopic expression of both genes in Arabidopsis promoted floral-organ abscission, and was accompanied by an early increase in the cytosolic pH of floral AZ cells—a phenomenon known to be linked with abscission, and by activation of cell separation in vestigial AZs. Finally, overexpression of both genes in an Atida mutant restored its abscission ability. Our results suggest roles for MiIDA1 and MiIDA2 in affecting mango fruitlet abscission. Based on our results, we propose new possible modes of action for IDA-like proteins in regulating organ abscission.
