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...

MetabolomicsDissecting Metabolism of Leaf Nodules in Ardisia crenata and Psychotria punctata
Root-microbe interaction and its specialized root nodule structures and functions are well studied. In contrast, leaf nodules harboring microbial endophytes in special glandular leaf structures have only recently gained increased interest as plant-microbe phyllosphere interactions. Here, we applied ...

TranscriptomicsHigh resolution temporal profiling of gene expression during Arabidopsis leaf development (senescence process)
Leaf senescence is an essential developmental process that involves altered regulation of thousands of genes and changes in many metabolic and signaling pathways resulting in massive physiological and structural changes in the leaf. The regulation of senescence is complex and although several senesc...

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.

ProteomicsPhosphoproteome of Thylakoid membrane in leaf senescence
Here, we investigated the role of STN7 kinase of photosynthetic protein complexes in leaf senescence. Defects in STN7 accelerated leaf yellowing and decreased the efficiency of leaf photosynthetic complexes. To identify STN7 targets, we profiled global proteomes and phosphoproteomes of thylakoid mem...

Proteomicsmaize leaf LC-MSMS
Constituting the final growth phase during the lifecycle of maize (Zea Mays L.), leaf senescence plays an important biological role in grain yield in crops. We undertook proteomic and physiological analyses in inbred line Yu816 in order to unravel the underlying mechanisms of leaf senescence induced...

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...

TranscriptomicsGenome-wide analysis of microRNAs and their targets involving in leaf senescence of rice
Enhancing grain production of rice (Oryza sativa L.) is a top priority in ensuring food security for human being. One approach to increase yield is to delay leaf senescence and to extend the available time for photosynthesis. microRNAs (miRNAs) are key regulators for aging and cellular senescence in...

TranscriptomicsA Local Regulatory Network Around Three NAC Transcription Factors in Stress Responses and Senescence in Arabidopsis leaves (Dark Induced Senescence).
A network model has been generated that describes the immediate gene expression cascade surrounding three similar but distinct NAC transcription factors that have roles to play in leaf senescence and in many stress responses in Arabidopsis. ANAC019, ANAC055 and ANAC072 belong to the same clade of N...
