The biophysical analysis using the Fluorescence Correlation Spectroscopy (FCS) on tobacco leaves stably overexpressing GFP-CDC48 revealed that the nuclear dynamics of CDC48 changed after treatment with cryptogein, an elicitor of immune responses. FCS analysis revealed an increase of the nuclear mobility of CDC48 and a faster interaction of CDC48 with a wide range of nuclear partners shortly after cryptogein treatment.

The carotenoid metabolic pathway is crucial for the accumulation of yellow pigments (e.g. lutein) in plant cells, with transcriptional regulation playing a key role in this process. Among these regulators, the MADS-box family represents one of the major transcription factor families involved in this regulatory network. To investigate the regulatory role of MADS-box family transcription factors in carotenoid metabolism in <i>Anthurium</i> spathes, a MADS-box gene from the light yellow spathe cultivar 'Vanilla' was cloned and designated as <i>AaCMB1</i>.

Transient overexpression of <i>AaCMB1</i> increased carotenoid accumulation in <i>Anthurium</i> spathes, and quantitative real-time polymerase chain reaction (qRT-PCR) analysis showed that overexpression of <i>AaCMB1</i> upregulated the expression of key structural genes in the carotenoid biosynthetic pathway.
