26S Proteasome Subunit SlPBB2 Regulates Fruit Development and Ripening in Tomato.
J Agric Food Chem

Fruit Biology Laboratory, College of Food Science and Nutritional Engineering, China Agricultural University, Beijing 100083, China.
Proteasomes are protein complexes responsible for degrading unneeded or damaged proteins through proteolysis and play critical roles in regulating plant development and response to environmental stresses. However, it is still unclear whether proteasomes regulate fruit development and ripening. In this study, we investigated the function of a core proteasome subunit, SlPBB2, in tomato fruit.

Functional analyses in yeast have shown that certain s/a mRNA/mRNA and mRNA/lncRNA pairs form stable double-stranded RNAs (dsRNAs) that affect transcript stability. Little is known, however, about the genome-wide prevalence of dsRNA formation and its potential functional implications during growth and development in diploid budding yeast.

The convoluted relationships between plants, viruses, and arthropod vectors housing bacterial endosymbionts are pivotal in the spread of harmful plant viral diseases. Endosymbionts play key roles in: manipulating host responses, influencing insect resistance to pesticides, shaping insect evolution, and bolstering virus acquisition, retention, and transmission. This interplay presents an innovative approach for developing sustainable strategies to manage plant diseases.

Overexpression of integrin β6 (ITGB6) is crucially linked to the invasion and metastasis of head and neck squamous cell carcinoma (HNSCC). The molecular mechanisms driving ITGB6 upregulation in HNSCC are not well understood. Our study comprehensively analyzed the transcriptional regulation and epigenetic modification mechanisms affecting ITGB6 transcription.

Proc Natl Acad Sci U S A

Department of Cell Biology, Emory University, Atlanta, GA 30322.
To regulate brain function, peripheral compounds must traverse the blood-brain barrier (BBB), an interface between the brain and the circulatory system. To determine whether specific transport mechanisms are relevant for sleep, we conducted a BBB-specific inducible RNAi knockdown (iKD) screen for genes affecting sleep in . We observed reduced sleep with knockdown of solute carrier , a carnitine transporter, as determined by isotope flux.
