Our results suggest that targeting RET in NEPC tumors with high RET expression could be an effective treatment option. Currently, there are limited treatment options for patients with aggressive neuroendocrine prostate cancer and none are curative. IMPLICATIONS Identification of aberrantly expressed RET kinase as a driver of tumor growth in multiple models of NEPC provides a significant rationale for testing the clinical application of RET inhibitors in patients with AVPC.The phenotypes of plants develop over time and change in response to the environment. New engineering and computer vision technologies track these phenotypic changes. Identifying the genetic loci regulating differences in the pattern of phenotypic change remains challenging. This study used functional principal component analysis (FPCA) to achieve this aim. Time-series phenotype data was collected from a sorghum (Sorghum bicolor) diversity panel using a number of technologies including RGB and hyperspectral imaging. This imaging lasted for thirty-seven days and centered on reproductive transition. A new higher density marker set was generated for the same population. Several genes known to control trait variation in sorghum have been previously cloned and characterized. These genes were not confidently identified in genome-wide association analyses at single time points. However, FPCA successfully identified the same known and characterized genes. FPCA analyses partitioned the role these genes play in controlling phenotypes. Partitioning was consistent with the known molecular function of the individual cloned genes. These data demonstrate that FPCA-based genome-wide association studies can enable robust time-series mapping analyses in a wide range of contexts. Moreover, time-series analysis can increase the accuracy and power of quantitative genetic analyses.Nα-terminal acetylation (NTA) is a prevalent protein modification in all eukaryotes. In plants, the biological function of NTA remains enigmatic. The dominant N-acetyltransferase (Nat) in Arabidopsis is NatA, which co-translationally catalyzes the acetylation of ~40% of the proteome. The core NatA complex consists of the catalytic subunit NAA10 and the ribosome-anchoring subunit NAA15. In human, fruit fly and yeast, this core NatA complex interacts with NAA50 to form the NatE complex. While in metazoa, NAA50 has N-acetyltransferase activity, yeast NAA50 is catalytically inactive and positions NatA at the ribosome tunnel exit. Here, we report the identification and characterization of Arabidopsis NAA50 (AT5G11340). Consistent with its putative function as co-translationally acting Nat, AtNAA50-EYFP localized to the cytosol and the endoplasmic reticulum, but also to the nuclei. this website We demonstrate that purified AtNAA50 displays Nα-terminal acetyltransferase and lysine-ε-autoacetyltransferase activity in vitro. Global N-acetylome-profiling of E. coli cells expressing AtNAA50 revealed the conservation of NatE substrate specificity between plants and humans. Unlike the embryo-lethal phenotype caused by the absence of AtNAA10 and AtNAA15, loss-of-NAA50 expression resulted in severe growth retardation and infertility in two Arabidopsis T-DNA insertion lines (naa50-1, naa50-2). The phenotype of naa50-2 was rescued by expression of HsNAA50 or AtNAA50. In contrast, the inactive ScNAA50 failed to complement naa50-2. Remarkably, loss-of-NAA50 expression did not affect NTA of known NatA substrates and caused the accumulation of proteins involved in stress responses. Overall our results emphasize a relevant role of AtNAA50 in plant defense and development, which is independent of the essential NatA activity.N1-methyladenosine is a unique type of base methylation in that it blocks Watson-Crick base pairing and introduces a positive charge. m1A is prevalent in yeast and mammalian mRNA and plays a functional role. However, little is known about the abundance, dynamics and topology of this modification in plant mRNA. Dot blotting and LC-MS/MS analyses revealed a dynamic pattern of m1A mRNA modification in various tissues and at different developmental stages of petunia (Petunia hybrida), a model system for plant growth and development. We performed transcriptome-wide profiling of m1A in petunia mRNA by m1A mRNA immunoprecipitation followed by a deep-sequencing approach (m1A-seq using an m1A-specific antibody). m1A-seq analysis identified 4993 m1A peaks in 3231 genes expressed in petunia corollas; there were 251 m1A peaks in which adenine residues were partly replaced by thymine (T) and/or reverse transcription stopped at an adenine site. m1A was enriched in coding sequences, with single peaks located immediately after start codons. Ethylene treatment up- and downregulated 400 and 603 m1A peaks in 375 and 530 mRNAs in petunia corollas, respectively, and 975 and 430 m1A peaks in mRNA were only detected in corollas treated with air and ethylene, respectively. Silencing of petunia tRNA-specific methyltransferase 61A (PhTRMT61A) reduced the m1A level in mRNA in vivo and in vitro. In addition, PhTRMT61A silencing caused abnormal leaf development, and the PhTRMT61A protein was localized to the nucleus. Thus, m1A in mRNA is an important epitranscriptome marker and plays a role in plant growth and development.The Aurora B kinase, encoded by the AURORA 3 (AUR3) gene in Arabidopsis thaliana, is a key regulator of cell division in all eukaryotes. Aurora B has at least two central functions during cell division; it is essential for the correct, i.e. balanced, segregation of chromosomes in mitosis and meiosis by controlling kinetochore function, and it acts at the division plane, where it is necessary to complete cytokinesis. To accomplish these two spatially distinct functions, Aurora B in animals is guided to its sites of action by Borealin, INCENP, and Survivin, which, together with Aurora B, form the chromosome passenger complex (CPC). However, besides Aurora homologs, only a candidate gene with restricted homology to INCENP has been described in Arabidopsis, raising the question of whether a full complement of the CPC exists in plants and how Aurora homologs are targeted subcellularly. Here, we have identified and functionally characterized a Borealin homolog, BOREALIN RELATED (BORR), in Arabidopsis. Together with detailed localization studies including the putative Arabidopsis INCENP homolog, these results support the existence of a CPC in plants.
