“…(1987) first identified a protein whose level dramatically increased in response to osmotic stress in cultured tobacco cells, and so named it osmotin. OLP families were later found to be universally present in plants and linked to a diverse range of biological processes, including fruit development and ripening ( Singh et al., 1985 ; Singh et al., 1987 ; Singh et al., 1989 ; Zhu et al., 1993 ; Sato et al., 1996 ; Raghothama et al., 1997 ; Faillace et al., 2019 ; Pluskota et al., 2019 ). While the OLP family was commonly thought to be related to plant stress responses, a number of studies have shown that the expression of some OLPs respond to phytohormones, such as ethylene, ABA and JA ( Singh et al., 1989 ; Zhu et al., 1993 ; Raghothama et al., 1997 ; Pluskota et al., 2019 ).…”

Here, we characterized the expression of members of the strawberry OLP family in the context of DOP and in response to treatment with ABA and JA.…”

“…In this current study, we first analyzed the characteristic changes in fruit water relations related to strawberry fruit development and ripening and showed that a DOP occurs during the ripening phase. To define DOP-associated biological processes in more detail, we characterized the expression patterns of a family of DOP-associated proteins, osmotin-like proteins (OLP), which are known to be tightly associated with the changes in the cellular osmotic potential ( Singh et al., 1985 ; Singh et al., 1987 ; Singh et al., 1989 ; Zhu et al., 1993 ; Sato et al., 1996 ; Raghothama et al., 1997 ; Faillace et al., 2019 ; Pluskota et al., 2019 ). Through analysis of a range of DOP-associated molecular and physiological events, we provide evidence that the fruit development-associated changes in osmotic potential contribute to the initiation of strawberry fruit ripening.…”

A Development-Associated Decrease in Osmotic Potential Contributes to Fruit Ripening Initiation in Strawberry (Fragaria ananassa)

Fruit development and ripening are accompanied by a large increase in cellular soluble solid contents, which results in a significant decrease in osmotic potential (DOP). Here, we report that this development-associated DOP contributes to the initiation of ripening in strawberry ( Fragaria ananassa Duch., Benihoppe) fruit. We show that fruit water potential significantly decreases at the onset of ripening as a result of the DOP. Further analysis using nuclear magnetic resonance spectroscopy (NMR) indicated that the change in fruit water potential was likely caused by catabolism of large molecules in receptacle cells, and bioinformatic analysis identified a family of osmotin-like proteins (OLP) that have a potential role in osmolyte accommodation. The gene expression of more than half of the OLP members increased substantially at the onset of fruit ripening, and specifically responded to DOP treatment, consistent with a close relationship between DOP and fruit ripening. We report that the DOP induced either by mannitol or water loss, triggered fruit ripening, as indicated by the elevated expression of multiple ripening genes and diverse ripening-associated physiological parameters. Collectively, these results suggest that the DOP contributes to strawberry fruit ripening initiation.

“…In the present study, we have identified a total of 26, 27, 39, 93 and 37 TLPs in the genome of B. distachyon, O. sativa, S. bicolor, T. aestivum and Z. mays , respectively. Previous studies reporting different numbers of TLPs in Arabidopsis (24), false brome (26), field mustard (20), grape (33), poplar (49), rice (49), sorghum (36), maize (49), moss (6) and white pine (10) [13-15, 47-49] suggests the presence of a varied number of TLPs in different plants. The higher number of TLPs in T. aestivum as compare to other species might be attributed to their complex allohexaploid genome configuration (AABBDD) [50].…”

BackgroundPR superfamily, pathogenesis related (PR) proteins divided into P1-PR17 subfamilies, is involved in the defense mechanism of plants. Thaumatin-like proteins (TLPs) are part of PR-5 family that facilitates resistance against abiotic and biotic stress responses.ResultsIn the present study, a total of 26, 27, 39, 93 and 37 TLPs with conserved signature-motif were identified in Brachypodium distachyon, Oryza sativa, Sorghum bicolor, Triticum aestivum and Zea mays, respectively. They were phylogenetically divided into 10 different clades. Majority of genes possessed one to three exons. Physicochemical analysis suggested significant differences between small and long TLPs. Majority consisted of signal peptide and localized in extracellular region. Evolutionary analyses suggested the role of duplication events in the expansion of this gene family. Tissue-specific expression of certain genes suggested their role in development, while differential expression revealed their putative roles in stress-response. The occurrence of assorted set of cis-regulatory elements further suggested their diverse functions. Co-expression analysis depicted their interaction with several stress responsive genes.ConclusionsThe detailed characterization of TLP proteins in cereals depicted their importance in combating various biotic and abiotic challenges. This study would be useful in further characterization of individual TLP genes in each plant, and various crop improvement programs in future studies.

BACKGROUNDRice is one of the most consumed cereals in the world. Productivity losses are caused by different biotic stresses. One of the most common is the phytophagous mite Schizotetranychus oryzae Rossi de Simons (Acari: Tetranychidae), which inhibits plant development and seed production. The identification of plant defense proteins is important for a better understanding of the mite‐plant interaction. We previously detected a high expression of Osmotin1 protein in mite‐resistant rice cultivars, under infested conditions, suggesting it could be involved in plant defense against mite attack. Therefore, we aimed to evaluate the responses of three rice lines overexpressing Osmotin1 (OSM1‐OE) and three lines lacking Osmotin1 gene (osm1‐ko) to mite attack.RESULTSThe number of individuals (adults, immature stages, and eggs) were significantly lower in OSM1‐OE lines than those in wildtype (WT) plants. On the other hand, the osm1‐ko lines showed larger numbers of mites per leaf than WT plants. When plants reached the full maturity stage, two out of the three infested OSM1‐OE lines presented lower plant height than WT, while the three osm1‐ko lines (infested or not) presented higher plant height than WT. The reduction in seed number caused by mite infestation was lower in OSM1‐OE lines (12–19%) than in WT plants (34%), while osm1‐ko lines presented higher reduction (24–54%) in seed number than WT plants (13%).CONCLUSIONThese data suggest that Osmotin1 is involved in rice resistance to S. oryzae infestation. This is the first work showing increased plant resistance to herbivory overexpressing an Osmotin gene.This article is protected by copyright. All rights reserved.
