“…Our post-harvest assays revealed a reduction in the polymer content in the skin of both pepper fruit types under 10°C and 20°C storage conditions, with those stored at 10°C displaying more substantial reductions. These observations are in line with reports of lowered total cutin content in orange ( Citrus sinenis L. Osbeck) fruit stored at 4°C and 25°C for 40 days [ 84 ], and cucumber ( C. sativus ) fruit stored at 10°C [ 11 ]. Our data do not reveal a clear pattern of change in specific cutin monomers and/or biochemical classes that are part of pepper fruit skins’ response to storage.…”

“…Lastly, we stained skin tissues with the fluorescent Fluorol Yellow 088 (FY 088) dye previously shown to interact with hydroxycinnamic components in the fruit skin cuticle, in addition to the suberized periderm cells in case formed in fleshy fruit such as reticulated melon [ 13 ], apple [ 53 , 54 ], mango [ 55 ], and cucumber [ 11 , 14 ]. Herein, the non-cracked skin of Numex Garnet displayed an intact cuticle throughout fruit development as detected both in Sudan IV ( Fig.…”

“…Interestingly, we recently showed that cracking in the skin of the Sikkim cucumber fruit ( Cucumis sativus var. sikkimensis ) actually reduces the rates of water loss and respiration during storage compared to those of the common cucumber fruit ( Cucumis sativus ) [ 11 ]. However, unlike Vezena Slatka fruit, the Sikkim cucumber produces a typical wound-periderm tissue made of suberin and lignin polymers that apparently acts as an efficient hydrophobic barrier, lessening transpiration and respiration through the skin.…”

“…It also reduces the fruit’s quality and marketability, owing to the damaged appearance [ 10 ]. Recently, skin cracking in cucumber fruit was shown to significantly affect fruit performance under various conditions of post-harvest storage [ 11 ]. Fruit skin failure typically occurs when the fruit skin cannot withstand the tension forces arising due to the ongoing strain applied on the outermost epidermal layer and skin tissues during fruit growth and expansion.…”

The hydrophobic cuticle encasing the fruit skin surface plays critical roles during fruit development and post-harvest. Skin failure often results in the fruit surface cracking and forming a wound-periderm tissue made of suberin and lignin. The factors that make the fruit skin susceptible to cracking have yet to be fully understood. Herein, we investigated two varieties of chili peppers (Capsicum annuum L.), Numex Garnet, whose fruit has intact skin, and Vezena Slatka, whose fruit has cracked skin. Microscopical observations, gas chromatography-mass spectrometry, biochemical and gene expression assays revealed that Vezena Slatka fruit form a thicker cuticle with greater levels of cutin monomers and hydroxycinnamic acids, and highly express key cutin-related genes. The skin of these fruit also had a lower epidermal cell density due to cells with very large perimeters, and highly express gene involved in epidermal cell differentiation. We demonstrate that skin cracking in the Vezena Slatka fruit is accompanied by a spatial accumulation of lignin-like polyphenolic compounds, without the formation of a typical wound-periderm tissues made of suberized cells. Lastly, we establish that skin cracking in chili-type pepper significantly affects fruit quality during post-harvest storage in a temperature-dependent manner. In conclusion, our data highlight cuticle thickness and epidermal cell density as two critical factors determining fruit skin susceptibility to cracking in chili-type pepper fruit.

“…sikkimensis ) have a wound-periderm resulting from extensive skin cracking throughout development. Microscopy and GC-MS analyses revealed the presence of phenolic-rich suberin in the fruit skin of mature Sikkim cucumbers that was not present in skin of mature common cucumbers [ 130 ]. QTL analysis found that the Rs (russet skin) locus controlled netting in Sikkim cucumber and could be mapped to a 736 kb region on chromosome 1 [ 131 ].…”

Cucumber (Cucumis sativus L.) fruits, which are eaten at an immature stage of development, can vary extensively in morphological features such as size, shape, waxiness, spines, warts, and flesh thickness. Different types of cucumbers that vary in these morphological traits are preferred throughout the world. Numerous studies in recent years have added greatly to our understanding of cucumber fruit development and have identified a variety of genetic factors leading to extensive diversity. Candidate genes influencing floral organ establishment, cell division and cell cycle regulation, hormone biosynthesis and response, sugar transport, trichome development, and cutin, wax, and pigment biosynthesis have all been identified as factors influencing cucumber fruit morphology. The identified genes demonstrate complex interplay between structural genes, transcription factors, and hormone signaling. Identification of genetic factors controlling these traits will facilitate breeding for desired characteristics to increase productivity, improve shipping, handling, and storage traits, and enhance consumer-desired qualities. The following review examines our current understanding of developmental and genetic factors driving diversity of cucumber fruit morphology.
