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...

TranscriptomicsDifferential gene expression studies for identifying genes imparting heat stress tolerance in wheat during grain filling.
Heat stress is one of the major abiotic stress factor that affects wheat yield. Especially, heat stress during grain filling affects grain yield besides reduced grain quality. So, in our present study, three genotypes with varied levels of tolerance to heat stress were chosen. They were subject...

TranscriptomicsTranscription profiling of rice wild type Zhonghua11 and mutant gif1 in filling stage
To reveal the underlying molecular mechanism of Gif1 action in the control of grain filling and yield improvement, we performed transcriptional profiling of wild type Zhonghua11 and mutant gif1 plants in early filling stage on a global scale using the Affymetrix GeneChip Rice Genome Array Experiment...

ProteomicsSpatial distribution of proteins and metabolites in developing wheat grain and their differential regulatory response during the grain filling process
Grain filling and proper grain development are essential biological processes in the plant’s life cycle, which majorly contributes to the final seed yield and quality in all cereal crop. However, very scarcely this knowledge is available in the literature regarding how the different wheat grain comp...

ProteomicsSWATH-MS quantitative analysis of proteins in the rice inferior and superior spikelets during grain filling
Modern rice cultivars have large panicle, however, yield potential of these cultivars is often not fully achieved due to the poor grain-filling of their late-flowering inferior spikelets (IS). Our earlier work suggests broad transcriptional reprogramming during grain filling and shows a difference i...

ProteomicsZmbZIP39 coordinates source-flow-sink relations to boost grain filling in maize
The orchestration of source, flow, and sink is fundamental to efficient grain filling in maize, yet the regulatory network synchronizing these processes remains a major enigma. To identify key regulators, we used the sucrose transporter ZmSUT1, a critical component of the ‘flow’ pathway, as a molecu...

ProteomicsComparative proteomics analysis of superior and inferior spikelets in hybrid rice during grain filling and response of inferior spikelets to drought stress using isobaric tags for relative and absolute quantification
The biological functions of differently expressed proteins between superior and inferior spikelet grains were investigated based on the isobaric tags for relative and absolute quantification to further clarify the mechanism of rice grain filling at the proteomic level, as well as the response of inf...

ProteomicsChanges in the nuclear proteome of developing wheat (Triticum aestivum L.) grain
Nuclear proteins of developing wheat grains collected during the cellularization, effective grain-filling and maturation phases of development were analysed.. Nuclear proteins were extracted and separated by two-dimensional gel electrophoresis. Image analysis revealed 371 and 299 reproducible spots ...
