MetabolomicsElevated temperature accelerates leaf senescence and promotes leaf nitrogen transport to improve rice grain protein synthesis
Elevated temperatures during grain filling severely constrain rice yield and quality. Although additional nitrogen can mitigate the adverse effects of elevated temperature, both factors increase grain protein content, and the underlying physiological mechanisms remain poorly understood. Here, we con...

MetabolomicsThe glycosyltransferase UGT76B1 modulates N-hydroxy-pipecolic acid homeostasis and plant immunity
The trade-off between growth and defense is a critical aspect of plant immunity. Therefore, the plant immune response needs to be tightly regulated. Salicylic acid (SA) is an important plant hormone regulating defense against biotrophic pathogens. Recently, N-hydroxy-pipecolic acid (NHP) was identif...

GenomicsMLL1 is essential for the senescence-associated secretory phenotype [ChIP-Seq]
Oncogene-induced senescence (OIS) and therapy-induced senescence (TIS), while tumor-suppressive, also promote procarcinogenic effects by activating the DNA damage response (DDR), which in turn induces inflammation. This inflammatory response prominently includes an array of cytokines known as the se...

TranscriptomicsDark-induced senescence time course of ANAC017 mutant lines in Arabidopsis
The role of ANAC017 in leaf senescence was assessed by covering leaf 6-7 of 5 week old plants. Samples of Col-0, anac017 knock-out and two ANAC017 overexpression lines were compared of day 0, 1 and 3 of the timecourse. ANAC017 OE lines show accelerated senescence during this time.

TranscriptomicsA gene regulatory network involving the class II ERF transcriptional repressors in leaf senescence of Arabidopsis thaliana
Leaf senescence is the final developmental process that includes the mobilization of nutrients from old leaves to newly growing tissues. The progression of leaf senescence requires dynamic but coordinated changes of gene expression. Although several transcription factors (TFs) are known to be involv...

TranscriptomicsInfluence of human P53 on plant gene expression
Mammalian p53 is a super tumor suppressor and plays a key role in guarding genome from DNA damage. However, p53 has not been found in plants which do not bear cancer although they constantly expose to ionizing radiation of ultraviolet light. Here we introduced p53 into the model plant Arabidopsis an...

TranscriptomicsGene expression profiling in senescence leaves from senescence-inducible LEC2 in Arabidopsis
The profiling was conducted with the 385K Microarray manufactured at NimbleGen, Inc (http://www.nimblegen.com/) designed from 30,386 genes of Arabidopsis (TAIR v.6). RNA samples of leaves of S1 (100% green leaf from 40 days plant) and S3 (more than 50% yellow leaf) senescence stages from senescence-...

ProteomicsPersulfidation of plant and bacteroid proteins is involved in legume nodule development and senescence
Legumes establish symbiosis with soil rhizobia forming root nodules that fix atmospheric nitrogen. The central role of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in nodule biology has been clearly established. Recently, hydrogen sulfide (H2S) and other reactive sulfur species ...

TranscriptomicsGene Expression Profiling of Glycine max Cotyledons and Trifoliate Leaves to Determine Genes Associated with Senescence
We use RNA sequencing technology in a time course study to measure transcript abundance from three developmental stages in cotyledons and five stages in the trifoliate leaf of Glycine max to identify genes with distinct temporal patterns of expression during leaf or cotyledon development. We also ex...

TranscriptomicsRegulation of Zn and Fe transporters by the GPC1 gene during wheat monocarpic senescence
TaGPC1 and TaGPC2 are NAC-domain transcription factors which accelerate the onset of senescence and facilitate nutrient translocation in wheat. We developed knockout mutants of these genes in tetraploid wheat and used RNA-seq to identify the effect of these mutations on the wheat flag leaf transcrip...
