TL;DR: It is shown that guard cells possess the entire ABA biosynthesis pathway and that it appears upregulated by positive feedback by ABA, highlighting the primacy of abscisic acid (ABA) in the stomatal response to drying air.

TL;DR: The interaction of P. indica with barley roots is characterized by combining global gene expression profiling, metabolic profiling, and genetic studies, revealing the complexity of compatibility mechanisms in host-microbe interactions, and identifying gibberellin signaling as potential target for successful fungi.

TL;DR: Control of tuber sprouting is a major objective in potato breeding because a large number of genes differentially expressed in growing versus dormant buds, and no master-regulator of potato tuber sprouted has been identified so far.

TL;DR: Transgenic tomato plants silenced for the major leaf cw-Inv isoforms restrict carbon export from source leaves and regulates the sucrose to hexose ratio in the apoplast, which may benefit bacteria since the longevity of host cells is raised and basal defense might be dampened.

TL;DR: In this paper, the authors established an in vitro assay using excised tuber buds to study the dormancy-releasing capacity of phytohormones cytokinins (CK) and gibberellins (GA) and showed that application of GA(3) is sufficient to induce sprouting.
