Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We investigated the morphological roots decisions of Arabidopsis in a NO3- heterogeneous medium. To do so, we used the Split-Root System which is an experimental set up to assess root decisions in nutrient heterogeneous medium. Split-root plants have been subjected to three different treatments. Control KNO3 plants received KNO3 on both sides of the root system (C.NO3) and Control KCl plants received KCl on both sides (C.KCl) as a nitrogen deprivation treatment. 'Split' plants received KNO3 on one side (Sp.NO3) and KCl on the other side (Sp.KCl) of the root system to assess the root decision-making in a heterogeneous environment.

Description
Living organisms have to cope with multiple and combined fluctuations in their environment. According to their sessile mode of life, plants are even more subjected to such fluctuations impacting their physiology and development. In particular, nutrient availability is known to tune plant development through modulating hormonal signaling, and conversely, hormonal signals are key to control nutrient related signaling pathways (Krouk et al., 2011a). However, very few is known about molecular mechanisms leading to plant adaptation to such combined signals. Here we deployed an unprecedented combinatorial treatment matrix to reveal plant adaptation in response to nitrate (NO3-), ammonium (NH4+), auxin (IAA), cytokinins (CK) and abscisic acid (ABA) and their exhaustive binary combinations.

Description
Ubiquitylation plays an important role in the control of Na+ homeostasis by the kidney. It is well established that the epithelial Na+ channel ENaC is regulated by the ubiquitin-protein ligase NEDD4-2, limiting ENaC cell surface expression and activity. Ubiquitylation can be reversed by the action of deubiquitylating enzymes (DUBs). One such DUB, USP2-45, was identified previously as an aldosterone-induced protein in the kidney, and is also a circadian output gene. In heterologous expression systems USP2-45 binds to ENaC, deubiquitylates it and enhances channel density and activity at the cell surface. Because the role of USP2-45 in renal Na+ transport had not been studied in vivo, we investigated here the effect of Usp2 gene inactivation in this process. We demonstrate first that the USP2-45 protein has a rhythmic expression with a peak at ZT12. Usp2-KO mice did not show any differences to wild-type littermates with respect to the diurnal control of Na+ or K+ urinary excretion and plasma levels neither on standard diet, nor after acute and chronic changes to low and high Na+ diets, respectively. Moreover, they had similar aldosterone levels either at low or high Na+ diet. Blood pressure measurements using telemetry did not reveal variations as compared to control mice. Usp2-KO did neither display alternations in ENaC or Na+,Cl--cotransporter (NCC) expression, nor were there any changes in regulatory protein levels, as evidenced by immunoblotting and transcriptome analysis. We conclude that USP2-45 is not crucial for the regulation of Na+ balance or maintenance of blood pressure in vivo.

Description
Transformation of the Arabidopsis ATHB17 gene into maize results in the expression of a truncated protein (smaller by 113 amino acids) that functions as a dominant-negative regulator that can modify activity of endogenous maize HD-Zip II transcription factors. This RNASeq experiment indicates that the observed effects of ATHB17d113 on the maize ear inflorescence and ear transcriptome are very small. Expression of ATHB17delta113 protein in maize leads to changes in ear growth resulting in increased ear size at early reproductive stages and, potentially increased sink size. Overall design: Two ATHB17delta113 expressing events (Event 1 and Event 2) were compared to control plants (herein referred to as WT) in the context of Monsanto Elite Maize hybrid line NN6306. Three bioreps of both Ear inflorescence and Ear tissues were sampled for the WT and each of the two transgenic events.
