TL;DR: The results indicated the existence of a substantial network of regulatory interactions and coordination occurring during plant defense among the different defense signaling pathways, notably between the salicylate and jasmonate pathways that were previously thought to act in an antagonistic fashion.

TL;DR: Using optical glucose sensors, a new class of sugar transporters are identified, named SWEETs, and it is shown that at least six out of seventeen Arabidopsis, two out of over twenty rice and two of seven homologues in Caenorhabditis elegans, and the single copy human protein, mediate glucose transport.

TL;DR: It is shown that resistance in barley requires a SNAP-25 (synaptosome-associated protein, molecular mass 25 kDa) homologue capable of forming a binary SNAP receptor (SNARE) complex with ROR2, and functions associated with SNARE-dependent penetration resistance are dispensable for immunity mediated by race-specific resistance (R) genes, highlighting fundamental differences between these two resistance forms.

TL;DR: A detailed analysis of Pi starvation-induced changes in gene expression of the entire genome of Arabidopsis correlated with biochemical processes enhances knowledge about molecular processes associated with Pi deficiency, but also facilitates the identification of key molecular determinants for improving Pi use by crop species.

TL;DR: It is reported that Arabidopsis PEN2 restricts pathogen entry of two ascomycete powdery mildew fungi that in nature colonize grass and pea species.
