PpNAC transcription factors regulate ENDOPOLYGALACTURONASE alleles and control peach fruit texture and stone adhesion.

Fruit texture variation in peach (Prunus persica L. Batsch), especially softening accompanied by the melting phase, directly affects marketability and storage. Two tandem endopolygalacturonase (endoPG) genes at the F-M locus, PGF and PGM, determine the melting or non-melting trait, which is associated with the freestone or clingstone trait.

Bioinspired energy-free temperature gradient regulator for significant enhancement of thermoelectric conversion efficiency.

Enhancing thermoelectric conversion efficiency (TCE) is pivotal for advancing global energy conservation and emission reduction initiatives. Traditional approaches primarily focus on microscopic strategies such as bandgap engineering, chemical potential adjustments, and entropy engineering. However, these methods face substantial limitations in practical applications due to challenging material property requirements.

CitGATA7 interact with histone acetyltransferase CitHAG28 to promote citric acid degradation by regulating the glutamine synthetase pathway in citrus.

Organic acid is a crucial indicator of fruit quality traits. Citric acid, the predominant organic acid in citrus fruit, directly influences its edible quality and economic value. While the transcriptional regulatory mechanisms of citric acid metabolism have been extensively studied, the understanding about the transcriptional and epigenetic co-regulation mechanisms is limited.

Thermal conduction force under standing and quasistanding temperature field.

Thermal conduction force plays a crucial role in manipulating the local thermal conductivity of crystals. However, due to the diffusive nature of thermal conduction, investigating the force effect is challenging. Recently, researchers have explored the force effect based on the wavelike behavior of thermal conduction, specifically second sound.

Tunable thermal conduction force without macroscopic temperature gradients.

Ubiquitous thermal conduction makes its force effect particularly important in diverse fields, such as electronic engineering and biochemistry. However, regulating thermal conduction force is still challenging due to two stringent restrictions. First, a temperature gradient is essential for inducing the force effect.

Comparative metabolomics provides novel insights into the basis of petiole color differences in celery ( L.).

Plant metabolites are important for plant development and human health. Plants of celery ( L.) with different-colored petioles have been formed in the course of long-term evolution.
