Abstract The strawberry is one of the world's most popular fruits, providing humans with vitamins, fibers, and antioxidants. Cultivated (Fragaria × ananassa) an allo-octoploid highly heterozygous, making it a challenge for breeding, quantitative trait locus (QTL) mapping, gene discovery. Some wild relatives, such as Fragaria vesca, have diploid genomes are becoming laboratory models cultivated strawberry. Recent advances in genome sequencing CRISPR-mediated editing greatly improved understanding various aspects growth development both strawberries. This review focuses on fruit quality traits that relevant to consumers, including aroma, sweetness, color, firmness, shape. Recently available phased-haplotype genomes, single nucleotide polymorphism (SNP) arrays, extensive transcriptomes, other big data made possible locate key genomic regions or pinpoint specific genes underlie volatile synthesis, anthocyanin accumulation sweetness intensity perception. These new will facilitate marker-assisted introgression missing into modern varieties, precise selected pathways. Strawberries poised benefit from these recent advances, consumers tastier, longer-lasting, healthier, more beautiful.

Abstract Anthocyanin is a vital indicator for both fruit nutritional and commercial value. accumulation surprisingly complicated process mediated by multiple networks associated with genetic, developmental, hormonal, environmental factors. Transcriptional regulation along epigenetic constitutes the dominant molecular framework anthocyanin biosynthesis. Here, we focus on current knowledge regulatory mechanisms of accumulation, emphasis latest progress in transcriptional crosstalk between various signaling pathways. We present an emerging picture how internal external stimuli control Additionally, discuss synergistic or antagonistic effect hormonal cues fruit.

Insights into transcription factors controlling strawberry fruit development and ripening

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: Oct. 10, 2022

Fruit ripening is a highly regulated and complex process involving series of physiological biochemical changes aiming to maximize fruit organoleptic traits attract herbivores, maximizing therefore seed dispersal. Furthermore, this key importance for quality consumer acceptance. In fleshy fruits, involves an alteration in color, the content sugars, organic acids secondary metabolites, such as volatile compounds, which influence flavor aroma, remodeling cell walls, resulting softening fruit. The mechanisms underlying these processes rely on action phytohormones, transcription factors epigenetic modifications. Strawberry considered model non-climacteric species, its mainly controlled by abscisic acid. Besides role phytohormones regulation strawberry ripening, number have been identified important regulators date. review, we present comprehensive overview current knowledge well compiling candidate that might play but not functionally studied

Transcription factors MdMYC2 and MdMYB85 interact with ester aroma synthesis gene MdAAT1 in apple

PLANT PHYSIOLOGY, Journal Year: 2023, Volume and Issue: 193(4), P. 2442 - 2458

Published: Aug. 17, 2023

Abstract Volatile esters in apple (Malus domestica) fruit are the critical aroma components determining flavor quality. While exact molecular regulatory mechanism remains unknown, jasmonic acid (JA) plays a crucial role stimulating synthesis of ester aromas apples. In our study, we investigated effects methyl jasmonate (MeJA) on production MeJA treatment significantly increased synthesis, accompanied by upregulation several genes involved pathway transduction. Specifically, expression gene MdMYC2, which encodes transcription factor associated with pathway, and R2R3-MYB MdMYB85 upon treatment. Furthermore, essential ALCOHOL ACYLTRANSFERASE 1 (MdAAT1), encoding an enzyme responsible for showed levels as well. Our investigation revealed that MdMYC2 directly interacted promoter region MdAAT1, thereby enhancing its transcriptional activity. addition, bind their promoters activate transcription. Notably, interaction between proteins further amplified effect well MdAAT1. Collectively, findings elucidate module consisting MdMYB85, MdAAT1 mediating JA promoting

Abstract Fruit color substantially affects consumer preferences, with darker red strawberries being economically more valuable due to their higher anthocyanin content. However, the molecular basis for dark coloration remains unclear. Through screening of an ethyl methanesulfonate mutant library, we identified a rg418 mutant, that demonstrated accumulation during early fruit development stages. Furthermore, ripening fruits this had content than wild-type (WT) fruits. An analysis flavonoid in WT and revealed substantial changes metabolic fluxes, exhibiting increased levels anthocyanins flavonols decreased proanthocyanidins. Bulked sergeant sequencing indicated gene was anthocyanidin reductase ( ANR ), key proanthocyanidin synthesis pathway. transcriptome expression MYB105 stage fruits, which promoted UFGT UDP-glucose 3-O-glucosyltransferase involved synthesis, thus enhancing Additionally, mutating white-fruited strawberry variant myb10 mutant) resulted appealing pink-colored suggesting diverse roles regulation. Our study provides theoretical insights improving color.

Fruit color is a very important external commodity factor for consumers. Compared to the most typical red octoploid strawberry (Fragaria × ananassa), pink often sells more expensive price and has higher economic benefit due its outstanding color. However, few studies have examined molecular basis of pink-colored fruit. Through an EMS mutagenesis woodland vesca), we identified mutant with fruits green petioles. Bulked-segregant analysis sequencing gene function verification confirmed that responsible mutation resides in encoding flavanone-3-hydroxylase (F3H) anthocyanin synthesis pathway. This nonsynonymous results arginine-to-histidine change at position 130 F3H. Molecular docking experiments showed reduction intermolecular force-hydrogen bonding between F3H protein substrates. Enzymatic greatly reduced ability mutated catalyze conversion substrates hence blockage The discovery key residue controlling provides clear target modification breeding varieties fruits, which may be great commercial value.
