“…Tomato photosynthesis is restricted to the green phases of development up until chloroplast-to-chloroplast differentiation, which is marked by the loss of chlorophyll, the degradation of the thylakoid membranes, and a strong decrease in the levels of photosynthesis-associated transcripts and proteins (Harris and Spurr, 1969a;Harris and Spurr, 1969b;Cheung et al, 1993;Barsan et al, 2012), after which the fruit continues to develop and ripen. This is similar for other fruits such as Capsicum annum (pepper) (Steer and Pearson, 1976), Citrus unshiu (satsuma mandarin) (Hiratsuka et al, 2015), blueberry (Birkhold et al, 1992); coffee (Coffea arabica) (Cannell, 1985;Lopez et al, 2000); Prunus tomentova (plum) (Aoyagi and Bassham, 1984); the ornamental plant Arum italicum (Ferroni et al, 2013) and Jatropha curcas (Ranjan et al, 2012). In satsuma mandarin, it has been demonstrated that photosynthesis occurs in these fruits, is greater at low irradiances, and increases with increasing [CO 2 ] supplied through fully developed stomata in the rind of satsuma (Hiratsuka et al, 2015).…”

The fact that stomata can be found in densities of about 72 mm À2 in immature Jatropha curcas fruit suggests that new carbon can be assimilated through these tissues (Ranjan et al, 2012).…”

Photosynthesis in non‐foliar tissues: implications for yield

Summary Photosynthesis is currently a focus for crop improvement. The majority of this work has taken place and been assessed in leaves, and limited consideration has been given to the contribution that other green tissues make to whole‐plant carbon assimilation. The major focus of this review is to evaluate the impact of non‐foliar photosynthesis on carbon‐use efficiency and total assimilation. Here we appraise and summarize past and current literature on the substantial contribution of different photosynthetically active organs and tissues to productivity in a variety of different plant types, with an emphasis on fruit and cereal crops. Previous studies provide evidence that non‐leaf photosynthesis could be an unexploited potential target for crop improvement. We also briefly examine the role of stomata in non‐foliar tissues, gas exchange, maintenance of optimal temperatures and thus photosynthesis. In the final section, we discuss possible opportunities to manipulate these processes and provide evidence that Triticum aestivum (wheat) plants genetically manipulated to increase leaf photosynthesis also displayed higher rates of ear assimilation, which translated to increased grain yield. By understanding these processes, we can start to provide insights into manipulating non‐foliar photosynthesis and stomatal behaviour to identify novel targets for exploitation in continuing breeding programmes.

“…the GCHXK and WT fruits (Figure 6). Confocal analysis of stomata of GCGFP citrus fruits revealed that, as demonstrated previously (Ben-Yehoshua et al, 1985;Hiratsuka et al, 2015), the stomatal pores of ripened yellow fruits are plugged (Figures 7D-I). However, GFP signal could still be observed in some of the plugged stomata (Figures 7D-F).…”

“…Stomata are also found on the hypocotyl and stem and have been observed on Arabidopsis and Lilium hyb. enchantment anthers and the fruit skins of apple (Malus domestica), banana (Musa acuminata), passionfruit (Passiflora edulis), pitaya (Hylocereus megalanthus), and citrus (Citrus unshiu) (Johnson and Brun, 1966;Blanke and Lenz, 1989;Clement et al, 1997;Wilson et al, 2011;Sánchez et al, 2013;Hiratsuka et al, 2015;Wei et al, 2018). Yet, the presence and temporal development of stomata on other flower parts, such as the petal, style, and ovule, have been the subject of very little study (Huang et al, 2018).…”

Expression of Hexokinase in Stomata of Citrus Fruit Reduces Fruit Transpiration and Affects Seed Development

The temporal formation and spatial distribution of stomata on the surface of citrus floral organs and, specifically, on the ovule from which the fruit develops, were analyzed using citrus plants that express green fluorescent protein (GFP) under the guard cell-specific KST1 promoter. Stomata are found on the style, sepal, and anther of the closed flower and on ovules from the stage of anthesis. It has previously been shown that hexokinase (HXK) mediates sugar-sensing in leaf guard cells and stimulates stomatal closure. The activity and response of citrus fruit stomata to sugar-sensing by HXK was examined using plants that express HXK under the KST1 promoter. Those plants are referred to as GCHXK plants. The transpiration of young green GCHXK citrus fruits was significantly reduced, indicating that their stomata respond to sugar similar to leaf stomata. Toward fruit maturation, fruit stomata are plugged and stop functioning, which explains why WT and GCHXK mature yellow fruits exhibited similar water loss. Seeds of the GCHXK plants were smaller and germinated more slowly than the WT seeds. We suggest that the stomata of young green citrus fruits, but not mature yellow fruits, respond to sugar levels via HXK and that fruit stomata are important for proper seed development.

“…Recently, Simkin et al [89] summarized the current literature to evaluate the contribution of different photosynthetically active organs to yield and quality of fruits and grain. Photosynthesis has been shown to occur in in petioles and stems [90], seeds [91], fruit [92][93][94][95] and wheat ears [96] as well as in the husks of corn [97] and it has been suggested that photosynthesis in these tissues could provide an alternative sources of photoassimilates essential for optimal yields and quality. Simkin et al [89] also showed that transgenic wheat with constitutively increased SBPase activity revealed increased gross photosynthesis in the ears in transgenic lines compared to wild type.…”

Increasing demands for food and resources are challenging existing markets, driving a need to continually investigate and establish crop varieties with improved yields and health benefits. By the later part of the century, current estimates indicate that a >50% increase in the yield of most of the important food crops including wheat, rice and barley will be needed to maintain food supplies and improve nutritional quality to tackle what has become known as ‘hidden hunger’. Improving the nutritional quality of crops has become a target for providing the micronutrients required in remote communities where dietary variation is often limited. A number of methods to achieve this have been investigated over recent years, from improving photosynthesis through genetic engineering, to breeding new higher yielding varieties. Recent research has shown that growing plants under elevated [CO2] can lead to an increase in Vitamin C due to changes in gene expression, demonstrating one potential route for plant biofortification. In this review, we discuss the current research being undertaken to improve photosynthesis and biofortify key crops to secure future food supplies and the potential links between improved photosynthesis and nutritional quality.
