In this Review, we examine the differences in functional traits that define each group’s distinctive role in the global carbon cycle and their sensitivity to climate change and ocean acidification. This synthesis reveals that a single representation of CaCO<sub>3</sub> in climate models is unlikely to accurately reflect system dynamics or their impacts on biogeochemical cycling under climate change.

Here we report the identification of the <i>spontaneous prehaustorium 1</i> (<i>spoh1</i>) mutant, which forms prehaustoria without external host signals. <i>spoh1</i> harbors a point mutation in the gene encoding uridine diphosphate–glucosyltransferase UGT72B1, an enzyme that glucosylates and thereby inactivates phenolic HIFs. PjUGT72B1 has a different substrate specificity than its ortholog of the host <i>Arabidopsis</i>. Introduction of PjUGT72B1 into <i>Arabidopsis</i> reduced prehaustorium induction activity, indicating that UGT72B1 regulates haustorium induction by hosts.

PER2-S662 phosphorylation correlated with genome-wide expression pathways that regulate polyunsaturated fatty acid (PUFA) conversion into oxylipins in the hypothalamus. Partial hydrogenation of dietary PUFAs increased hypothalamic PER2-S662 phosphorylation and entrainment to a summer photoperiod in control mice, but not in mice for which PER2-S662 could not be phosphorylated.
