Abstract Organ abscission is essential for optimal reproduction, yet its regulation in perennial woody plant species is poorly understood. To investigate how abscission is spatially and temporally regulated during reproduction, we analyzed five sequential abscission events in the cherry species Prunus yedoensis and Prunus sargentii: abscission of the petals, calyces, flower pedicels, fruit pedicels, and peduncles.

Septicemia-causing Vibrio vulnificus produces at least three exoproteases, VvpE, VvpS and VvpM, all of which participate in interactions with human cells. Expression of VvpE and VvpS is induced in the stationary phase by multiple transcription factors including Sigma S, SmcR, and cAMP-CRP complex. Distinct roles of VvpM, such as induction of apoptosis, lead us to hypothesize VvpM expression is different from that of the other exoproteases.
