“…Studies on cherry cracking have focused on water movement at the plant and fruit levels [8][9][10], on the mechanisms involved in the deposition and cracking of the cuticle [11,12], and on the strain of the fruit skin [10,[13][14][15]. In this regard, the possibility that increased water permeability could be mediated by aquaporins (AQPs) in more susceptible cultivars is a particularly attractive hypothesis.…”

The involvement of aquaporins in rain-induced sweet cherry (Prunus avium L.) fruit cracking is an important research topic with potential agricultural applications. In the present study, we performed the functional characterization of PaPIP1;4, the most expressed aquaporin in sweet cherry fruit. Field experiments focused on the pre-harvest exogenous application to sweet cherry trees, cultivar Skeena, with a solution of 0.5% CaCl2, which is the most common treatment to prevent cracking. Results show that PaPIP1;4 was mostly expressed in the fruit peduncle, but its steady-state transcript levels were higher in fruits from CaCl2-treated plants than in controls. The transient expression of PaPIP1;4-GFP in tobacco epidermal cells and the overexpression of PaPIP1;4 in YSH1172 yeast mutation showed that PaPIP1;4 is a plasma membrane protein able to transport water and hydrogen peroxide. In this study, we characterized for the first time a plasma membrane sweet cherry aquaporin able to transport water and H2O2 that is upregulated by the pre-harvest exogenous application of CaCl2 supplements.

“…2). Most similar studies use linear variable displacement transducers or similar for the continuous measurement of fruit diameter to esti- mate fruit weight or volume (Araki et al, 2004;Brüggenwirth et al, 2016;Greenspan et al, 1994Greenspan et al, , 1996Guichard et al, 2005;Kitano and Araki, 2001;Lang, 1990;Morandi et al, 2014). In this study, however, we used digital calipers (Hossain and Nonami, 2010) because we needed to measure many fruits (>100) in a short time.…”

“…In this study, we used the heat-girdling method, heating or steaming the peduncle to kill phloem cells and restrict the phloem influx to fruit because this has been used to estimate transpiration and there are many reports in fruit trees such as Vitis vinifera L. (Greenspan et al, 1994(Greenspan et al, , 1996Lang and Thorpe, 1989), Malus pumila L. (Lang, 1990), Prunus persica (L.) Batsch (Fishman et al, 2001;Morandi et al, 2014), and P. avium L. (Brüggenwirth et al, 2016). In addition, systematic errors are very small in the short term with a statistically sufficient sample, and this is the only method that allows the estimation of xylem and phloem influx and transpiration in the greenhouse (Fishman et al, 2001) using the heat-girdling method because it is available for greenhouse tomato production and can evaluate many fruits in a short time.…”

Fruit growth represents the balance between material influxes via xylem and phloem and efflux by transpiration via the stomata of the calyx and cuticle of fruit, which determines the yield and soluble solids content (SSC). Knowledge of these factors is important for the production of high-SSC tomato fruit, but no physiological indicator is available to allow prediction of fruit yield and SSC for breeding and crop production purposes. To identify indicators, we grew Japanese, Dutch, Japanese × Dutch, and high-SSC cultivars and sought correlations of the fluxes to fruit with yield and SSC. To estimate the contributions of the xylem, phloem, and transpiration fluxes to fruit weight increase, we measured 2-day growth rates of intact, detached, and heat-girdled (peduncle steamed for 90 to 120 s) fruits treated at 14, 28, or 42 days after flowering (DAF). Xylem influx was much lower in the high-SSC cultivar than in the others. Phloem influx was lower in the Dutch and hybrid cultivars at 28 DAF. Transpiration efflux was greater in the Japanese cultivar at 42 DAF. Fruit growth rate at 14 DAF was positively correlated with yield, and phloem influx per fruit weight increase at 14 and 28 DAF was positively correlated with SSC. These results show how the xylem, phloem, and transpiration fluxes of fruit can predict fruit yield and SSC. This information will help the production and breeding of high-SSC fruit.

“…Similar questions must be posed with regard to the possibility of metal gradients occurring within the xylem, which could arise as a result of abstraction of metals during upward flow of the transpiration stream. Such an occurrence is possible; as the perfusion studies [70][71][72][73] which have been demonstrated, and suggests that standardisation of sampling height is necessary in comparative studies.…”
