“…The IQ domain proteins play crucial roles in plant organ development and shape as well as tolerance to drought stress (Duan et al, 2017;Lazzaro et al, 2018). Previous GWAS and integrated omics reports showed IQ domain proteins to be involved in fruit shape and elongation in watermelon and tomatoes (Dou et al, 2022(Dou et al, , 2018Guo et al, 2019;Rodriguez et al, 2011). The WD40 repeat proteins play important roles in many plant development processes including cell division, floral development, and meristem organization (Stirnimann et al, 2010).…”

Fruit quality traits are crucial determinants of consumers’ willingness to purchase watermelon produce, making them major goals for breeding programs. There is limited information on the genetic underpinnings of fruit quality traits in watermelon. A total of 125 citron watermelon (Citrullus amarus) accessions were genotyped using single nucleotide polymorphisms (SNPs) molecular markers generated via whole‐genome resequencing. A total of 2,126,759 genome‐wide SNP markers were used to uncover marker‐trait associations using single and multi‐locus GWAS models. High broad‐sense heritability for fruit quality traits was detected. Correlation analysis among traits revealed positive relationships, with the exception of fruit diameter and fruit shape index (ratio of fruit length to fruit diameter), which was negative. A total of 37 significant SNP markers associated with soluble solids content, flesh color, fruit length, fruit diameter, and fruit shape index traits were uncovered. These peak SNPs accounted for 2.1%–23.4% of the phenotypic variation explained showing the quantitative inheritance nature of the evaluated traits. Candidate genes relevant to fruit quality traits were uncovered on chromosomes Ca01, Ca03, Ca06, and Ca07. These significant molecular markers and candidate genes will be useful in marker‐assisted breeding of fruit quality traits in watermelon.

The tomato is a convenient object for studying reproductive processes, which has become a classic. Such complex processes as flowering and fruit setting require an understanding of the fundamental principles of molecular interaction, the structures of genes and proteins, the construction of signaling pathways for transcription regulation, including the synchronous actions of cis-regulatory elements (promoter and enhancer), trans-regulatory elements (transcription factors and regulatory RNAs), and transposable elements and epigenetic regulators (DNA methylation and acetylation, chromatin structure). Here, we discuss the current state of research on tomatoes (2017–2023) devoted to studying the function of genes that regulate flowering and signal regulation systems using genome-editing technologies, RNA interference gene silencing, and gene overexpression, including heterologous expression. Although the central candidate genes for these regulatory components have been identified, a complete picture of their relationship has yet to be formed. Therefore, this review summarizes the latest achievements related to studying the processes of flowering and fruit set. This work attempts to display the gene interaction scheme to better understand the events under consideration.

“…Higher expression of CitOFP19 leads to pear-shaped ovary and fruit shape in tomato ( Wu et al., 2022 ). Overexpression of watermelon ClIQD24 in tomato causes an elongated tomato fruit shape ( Dou et al., 2022a ). Overexpression of melon IQD / SUN genes ( CmSUN23-24 or CmSUN25-26-27c ) leads to an elongated fruit shape, while overexpression of GhIQD10 inhibits cotton fiber length ( Ma et al., 2022b ; Xu et al., 2023 ).…”

Shape is a primary determinant of consumer preference for many horticultural crops and it is also associated with many aspects of marketing, harvest mechanics, and postharvest handling. Perceptions of quality and preference often map to specific shapes of fruits, tubers, leaves, flowers, roots, and other plant organs. As a result, humans have greatly expanded the palette of shapes available for horticultural crops, in many cases creating a series of market classes where particular shapes predominate. Crop wild relatives possess organs shaped by natural selection, while domesticated species possess organs shaped by human desires. Selection for visually-pleasing shapes in vegetable crops resulted from a number of opportunistic factors, including modification of supernumerary cambia, allelic variation at loci that control fundamental processes such as cell division, cell elongation, transposon-mediated variation, and partitioning of photosynthate. Genes that control cell division patterning may be universal shape regulators in horticultural crops, influencing the form of fruits, tubers, and grains in disparate species. Crop wild relatives are often considered less relevant for modern breeding efforts when it comes to characteristics such as shape, however this view may be unnecessarily limiting. Useful allelic variation in wild species may not have been examined or exploited with respect to shape modifications, and newly emergent information on key genes and proteins may provide additional opportunities to regulate the form and contour of vegetable crops.
