“…Thus, RBPs may function in both the nucleus and cytoplasm. MhYTP1 and MhYTP2 occur throughout the entire cell rather than within only specific compartments (Wang et al, 2017c). Otherwise, AtYTH5 and AtYTH7 in A. thaliana have also been shown to localize throughout the leaf cells of N. benthamiana (Li et al, 2014).…”

“…MhYTP2 can interact with acireductone dioxygenase 4 [an ethylene (ET) biosynthesis-related protein] to promote the progress of maturity (Wang et al, 2017a). The fruits of both MhYTP1 and MhYTP2 transgenic tomato plants turned yellow earlier than did those of wild-type plants, indicating that these two YTH domain-containing genes can promote fruit ripening in tomato (Wang et al, 2017c). In two different cultivars, the expression of CitYTH5 and CitYTH10 was higher in peels of early cultivars, whereas the expression of CitYTH1, 7, 8, and 9 was lower ( Fig.…”

“…Overexpression of MhYTP1 or MhYTP2 makes plants more sensitive to NaCl, but more resistant to nutrient deficits (Wang et al, 2017b). In addition, Wang et al (2017c) reported that, compared with wild-type plants, plants overexpressing MhYTP1 or MhYTP2 were more sensitive to heat stress and high salinity but were more resistant to waterlogging, chilling, drought, and nutrient deficiency conditions. Moreover, both the MhYTP1 and MhYTP2 genes in those overexpression plants could be induced by various treatments (e.g., water logging, water deficit, and high salinity).…”

In eukaryotic systems, messenger RNA regulations, including splicing, 3′-end formation, editing, localization, and translation, are achieved by different RNA-binding proteins and noncoding RNAs. The YTH domain is a newly identified RNA-binding domain that was identified by comparing its sequence with that of splicing factor YT521-B. Previous study showed that the YTH gene plays an important role in plant resistance to abiotic and biotic stress. In this study, 211 YTH genes were identified in 26 species that represent four major plant lineages. Phylogenetic analysis revealed that these genes could be divided into eight subgroups. All of the YTH genes contain a YT521 domain and have different structures. Ten YTH genes were identified in navel orange (Citrus sinensis). The expression profiles of these CitYTH genes were analyzed in different tissues and at different fruit developmental stages, and CitYTH genes displayed distinct expression patterns under heat, cold, salt, and drought stress. Furthermore, expression of the CitYTH genes in response to exogenous hormones was measured. Nuclear localization was also confirmed for five of the proteins encoded by these genes after transient expression in Nicotiana benthamiana cells. This study provides valuable information on the role of CitYTHs in the signaling pathways involved in environmental stress responses in Citrus.

The first YTH domain-containing RNA binding protein (YTP) was found in rat, where it was related to oxidative stress. Unlike characterizations in yeast and animals, functions of plant YTPs are less clear. Malus hupehensis (Pamp.) Rehd. YTP1 and YTP2 (MhYTP1 and MhYTP2) are known to be active in leaf senescence and fruit ripening. However, no research has been published about their roles in stress responses. Here, we investigate the stress-related functions of MhYTP1 and MhYTP2 in Arabidopsis thaliana. Both of the two genes participated in salicylic acid (SA), jasmonic acid (JA), and abscisic acid (ABA) signaling and play roles in plant responses to oxidative stress, chilling, high temperature, high salinity, and mannitol induced physiological drought stress. Moreover, MhYTP1 plays leading roles in SA and ABA signaling, and MhYTP2 plays leading roles in JA signaling and oxidative stress responses. These results will fill a gap in our knowledge about plant YTPs and stress responses and provide a foundation for future attempts to improve stress tolerance in apple.

Determination of the relationship between respiration rate and ethylene production by fruit sizes of different tomato types

BACKGROUND Tomatoes of different types and cultivars are grown in different parts of the world. Accordingly, the phenological, pomological and biochemical characteristics of these types and cultivars may differ from each other, and therefore their ripening behaviours may also differ. The present study aimed to determine the respiration rate and ethylene production of twelve commonly grown cultivars in Turkey at harvest and during the ripening stage. The fruits were harvested at the mature green stage and categorized according to their size as small, medium and large‐fruited cultivars. RESULTS At harvest time, the highest respiration rate was determined from ‘Moda’ (small‐fruited) cultivar and the lowest was from ‘Elips’ (medium‐fruited). The highest ethylene production was determined from ‘Sarikiz’ (small‐fruited) and the lowest was from ‘Alberty’ (large‐fruited). All tomato cultivars examined in the study showed climacteric respiration behavior during the ripening, and it was determined that small‐fruited types had a higher respiration rate and ethylene production compared to medium and large‐fruited ones. ‘Sarikiz’ (small‐fruited) had the highest climacteric peak and ‘Gulpembe’ (large‐fruited) had the lowest. Moreover, it was determined that the respiration rate of small‐fruited cultivars were 5.01‐fold higher compared to other cultivars and this type of cultivars produced 4.19‐fold higher ethylene compared to big‐fruited cultivars at harvest. Medium‐fruited tomatoes had 1.90‐fold higher respiration rate and 1.64‐fold ethylene production compared to big‐fruited tomatoes. CONCLUSION It was determined that fruit size and respiration rate were related independently of the cultivars, although there was no relationship between fruit size and ethylene production. © 2022 Society of Chemical Industry.
