Parthenocarpy in Cucurbitaceae: Genetic Regulation, Hormonal Crosstalk, and Breeding Implications

Genetic and molecular mechanisms regulating parthenocarpy: Paradigms from cucumber and initial exploration in other Cucurbitaceae crops

Parthenocarpy, the ability to set fruit without pollination and fertilisation, is an important crop trait that helps stabilise yield in Cucurbits under unfavourable environmental or indoor farming conditions. While cucumber ( Cucumis sativus L.) is widely recognised as the primary model for parthenocarpy research...

Regulation of parthenocarpic fruit set in novel seedless triploid and diploid mandarins

Aim of study: Ploidy management is a strategy for obtaining seedless mandarins worldwide. The mechanisms underlying parthenocarpy in triploid genotypes and their response to horticultural management have not been evaluated. This work aimed to analyse how triploidy affects the hormonal and nutritional mechanisms that in...

Jasmonic acid-mediated starch degradation regulates male fertility in cucumber.

Autotetraploid Breeding in Perennial Rye (Secale cereanum): Cytogenetic Challenges, Agronomic Potential, and Future Prospects

Perennial rye (Secale cereanum), an interspecific hybrid derived from cultivated rye (Secale cereale L.) and perennial wild rye (Secale strictum), has potential for the development of more sustainable perennial cereal systems. However, its breeding and agronomic utilization are constrained by low fertility and irregula...

SDR3.1 negatively regulates seed dormancy in Poaceae crops.

Elucidating the molecular mechanisms that govern seed dormancy is important for developing crops with improved resistance to preharvest sprouting (PHS). A series of seed dormancy genes have been cloned, but the connections among different seed dormancy genes remain poorly understood. Here, we have revealed the relation...

Independent evolution of flavour and parthenocarpy in fig, one of the earliest domesticated fruit trees

Domestication often modifies multiple traits in concert, but whether fruit quality and reproductive mode share a genetic basis in perennial crops has not been tested at multi-omics resolution. In fig (Ficus carica), one of the earliest domesticated fruit trees and a crop with archaeobotanical evidence of cultivation ov...
