RNA sequencing and histology analysis provide insights into the formation of hollow fruits in cucumber.

ABSTRACT:

Background

Hollow heart is a common physiological disorder in cucumber (Cucumis sativus L.) characterized by internal fruit cavities that are not visible externally, severely compromising fruit quality and marketability. Although previous studies have implicated both genetic and environmental factors, the molecular regulatory mechanisms, particularly the role of long non-coding RNAs (lncRNAs), remain largely uncharacterized.

Results

In this study, we conducted an integrated histological and transcriptomic analysis to elucidate the regulatory basis of the hollow heart trait using two cucumber sister lines: H6 (hollow fruit) and H7 (non-hollow fruit). Histological observations revealed that the hollow heart trait emerges approximately two days after anthesis (DAA), marked by t
