TLDR
Data strongly suggest that AtNAP and its homologs play an important role in leaf senescence in Arabidopsis and possibly in other plant species.
Transcriptome of Arabidopsis leaf senescence
TLDR
This study revealed ESTs for 98 annotated genes for which ESTs did not previously exist and 46 novel transcribed units that have not previously been annotated in the Arabidopsis genome.
The EPIP Peptide of INFLORESCENCE DEFICIENT IN ABSCISSION Is Sufficient to Induce Abscission in Arabidopsis through the Receptor-Like Kinases HAESA and HAESA-LIKE2[W][OA]
TLDR
It is proposed that IDA and the IDL proteins constitute a family of putative ligands that act through RLKs to regulate different events during plant development.
Leaf senescence: signals, execution, and regulation.
CLAVATA2 forms a distinct CLE-binding receptor complex regulating Arabidopsis stem cell specification.
TLDR
It is shown that BAM and CLV1 overexpression can compensate for the loss of CLV2 function in vivo and suggest two parallel ligand-binding receptor complexes controlling stem cell specification in Arabidopsis.
An Arabidopsis Mitogen-Activated Protein Kinase Cascade, MKK9-MPK6, Plays a Role in Leaf Senescence1[C][W][OA]
TLDR
A MAPK cascade involving MKK9-MPK6 is shown to play an important role in regulating leaf senescence in Arabidopsis (Arabidopsis thaliana) and the prematuresenescence phenotype is suppressed when MKK 9 is overexpressed in the mpk6 null background.
Characterization of a CLE processing activity
TLDR
Analysis of an in vitro CLE processing activity is extended and shows that in vitro cleavage occurs at Arg70, exactly matching in vivo maturation, and it is shown that efficient protease recognition can occur with as little as four residues upstream of the CLE domain.
Convergence and divergence in gene expression profiles induced by leaf senescence and 27 senescence-promoting hormonal, pathological and environmental stress treatments.
TLDR
By analysing microarray expression data from 27 different treatments and comparing them with that from developmental leaf senescence, it is shown that at early stages of treatments, different hormones and stresses showed limited similarity in the induction of gene expression to that of developmental leafsenescence.
AtMYB2 Regulates Whole Plant Senescence by Inhibiting Cytokinin-Mediated Branching at Late Stages of Development in Arabidopsis1[C][W][OA]
TLDR
An AtMYB2-regulated post apical dominance mechanism by which Arabidopsis (Arabidopsis thaliana) inhibits the outgrowth of axillary buds as part of the whole plant senescence program is reported.
Mechanisms of Molecular Mimicry of Plant CLE Peptide Ligands by the Parasitic Nematode Globodera rostochiensis1[C][W]
TLDR
It is demonstrated that GrCLE1 maturation can be entirely carried out by plant factors and that the availability of CLE processing activity may be essential for successful ligand mimicry.
