Maybe it's just me, maybe it's just the city I live in... but I don't think so. Why does the snow around trees melt the quickest? And I'm not just talking about trees that are elevated for one reason or another (i.e. because of their roots, etc.), I'm talking about all trees... or maybe just deciduous ones, I didn't check my evergreens...

My drywall (plaster) spackling compound has been sealed up for a year last time I used it. When I opened it yesterday, it had what looks like mold (fuzzy, white) growing on it. What can survive on spackling compound (gypsum and water)? What does it metabolize???

The parallel induction of both PEPCase and PEPCase-K during the transition from C3 -CAM metabolism by salt stress provides support to the close linkage between the enzyme and the associated kinase The functioning of a signal transduction cascade in which phosphoinositide-specific phospholipase C catalyzes the production of the 2nd messenger inositol-1,4,5-trisphosphate for the stimulation of Ca2+ efflux from vacuole to cytosol. Upon increase of Ca2+, a Ca2+-dependent protein kinase stimulates translation of PEPCase-K mRNA or a putative activation factor. Most probable is cytosolic pH because of up-regulation of PEPCase-K and the associated phosphorylation of the up-regulation of PCase are highly stimulated by alkalinization of cytosol. In CAM plants, transcripts of the Ppck gene accumulate at night, causing accumulation of PCase-K and phosphorylation of PCase These contain further levels of regulation for the photosynthetic process. Salt-stress induces the rapid expression of Ppc genes
