TL;DR: The cloning and characterization from the flowering plant Arabidopsis thaliana of a cDNA clone named PP1‐At which is highly homologous to protein phosphatase 1 is reported which can rescue a semidominant mutant, cold sensitive (cs) dis2‐11, which under nonpermissive conditions is unable to complete chromosome disjunction.

TL;DR: Recent progress in study of gravitropism is summarized and strategies to identify the molecular basis of the gravity response in Arabidopsis thaliana are discussed, which will put us on a road towards the molecular systems biology of theArabidopsis gravitopic response.

TL;DR: It is proved that IAR3, ILL2 and ILR1 reside in the endoplasmic reticulum, indicating that in this compartment the hydrolases regulate the rates of amido-IAA hydrolysis which results in activation of auxin signaling.

TL;DR: It is shown that auxins and functional analogues compete with [3H]N3IAA for binding to pm23, and it is found that PAB130, a polyclonal antibody raised against auxin-binding protein 1, recognized ABP-1 as well aspm23, which suggests that pm23 shares common epitopes with ABp-1.

TL;DR: How recent breakthroughs in the analysis and understanding of eucaryotic signal transduction are being applied are described, in conjunction with technical advances in molecular genetics, to elucidate the molecular basis of the phytohormonal properties of auxin are described.
