“…Transcription factors are well known to be involved in plant growth and tuber formation, including starch biosynthesis, regulation of fruit size, formation of cambium meristems, and hormone biosynthesis [ 45 , 51 , 52 ]. Several MADS-box genes have been shown to be highly expressed in tubers, including MADS3 , MADS4 , AGL24 , MDAS11 , MADS16 , MADS1 , SDR1 , SOC1 , and FUL1 [ 53 , 54 , 55 , 56 ]. In turn, Ku et al [ 53 ] observed that IbMADS1-transformed potatoes exhibited tuber morphogenesis in fibrous roots, and Noh et al [ 55 ] reported that SRD1 plays a role in the formation of storage roots by activating the proliferation of cambium and metaxylem cells to induce initial thickening growth of storage roots.…”

Chayote (Sechium edule) produces edible tubers with high starch content after 1 year of growth but the mechanism of chayote tuberization remains unknown. ‘Tuershao’, a chayote cultivar lacking edible fruits but showing higher tuber yield than traditional chayote cultivars, was used to study tuber formation through integrative analysis of the metabolome and transcriptome profiles at three tuber-growth stages. Starch biosynthesis- and galactose metabolism-related genes and metabolites were significantly upregulated during tuber bulking, whereas genes encoding sugars will eventually be exported transporter (SWEET) and sugar transporter (SUT) were highly expressed during tuber formation. Auxin precursor (indole-3-acetamide) and ethylene precursor, 1-aminocyclopropane-1-carboxylic acid, were upregulated, suggesting that both hormones play pivotal roles in tuber development and maturation. Our data revealed a similar tuber-formation signaling pathway in chayote as in potatoes, including complexes BEL1/KNOX and SP6A/14-3-3/FDL. Down-regulation of the BEL1/KNOX complex and upregulation of 14-3-3 protein implied that these two complexes might have distinct functions in tuber formation. Finally, gene expression and microscopic analysis indicated active cell division during the initial stages of tuber formation. Altogether, the integration of transcriptome and metabolome analyses unraveled an overall molecular network of chayote tuberization that might facilitate its utilization.

“…Seeds begin to sprout and develop into the same plant as the seed through the process of sprouting. Under normal storage conditions, sweet potatoes are intended to sprout after a short dormancy period (about 2-4 weeks) [30]. Sprouting during storage depletes nutrients, which reduces the quality of the roots.…”

Sweet potato (Ipomoea batatas (L.) Lam.) is served as an important root crop worldwide due to its high yield, strong adaptability and nutrient richness. Sweet potato has played a significant role in ensuring food security and family income opportunities for local populations in China for years of experience. The storage roots, which provide abundant nutrition and health benefits to people, are the mainly harvested and consumed parts of sweet potato. However, after harvest, physiological disorders, such as sprouting, mechanical injury and infectious postharvest diseases, increase the magnitude of sweet potato root quality decline and nutritional compound losses. Ethylene and 1-methylcyclopropene (1-MCP) were considered to be effective commercial treatments in sweet potato postharvest. Exogenous ethylene and 1-MCP treatment could successfully inhibit root sprouts and reduce rot decay without affecting the storage quality of sweet potato. This review aims to summarize the latest available information on the effects of ethylene and 1-MCP with respect to enhancing or impairing sweet potato root quality. A better understanding of the influence of ethylene and 1-MCP on root quality parameters will be useful to further explore the role and mechanisms of action of ethylene in regulating the postharvest storage of sweet potato roots and contributions to technological development and innovation.
