TL;DR: The first molecular components that control lateral root founder cell identity in the Arabidopsis root are identified, including an IAA28-dependent auxin signaling module in the basal meristem region that regulates GATA23 expression and thereby lateral rootfounder cell specification and root branching patterns.

TL;DR: A high-throughput, automatic method to trace Arabidopsis seedling roots grown on agarose plates that requires minimal interaction from the user and is able to process long time-lapse sequences with user interaction only required on the first frame.

TL;DR: In this paper, the authors analyzed genome expression in Arabidopsis thaliana mutants defective in seed ABA synthesis (aba1-1) or perception (abi1 -1) and found that these mutants exhibited changes in global gene expression resulting from dry AR that were comparable with changes occurring in wild type (WT) seeds.

TL;DR: The N-end rule pathway targets protein degradation through the identity of the amino-terminal residue of specific protein substrates in Arabidopsis thaliana, and two components of this pathway, PROTEOLYSIS6 (PRT6) and arginyl-tRNA:protein arginially transferase (ATE), were shown to regulate seed after-ripening, seedling sugar sensitivity, seedlings lipid breakdown, and abscisic acid (ABA) sensitivity of germination as mentioned in this paper.

TL;DR: Integrated mathematical modeling and experiments are used to understand how feedback loops interact to control gibberellin signaling and find that regulation of GA20ox transcription plays a significant role in both modulating the level of endogenous gibbEREllin and generating overshoots after the removal of exogenous gibb Berellin.
