Protein content (PC) is a crucial factor that determines the end-use and nutritional quality of wheat (Triticum aestivum). Glutamine synthetase (GS), which is a major participant in nitrogen metabolism, can convert inorganic nitrogen into organic nitrogen. Although many studies have been conducted on PC and GS, a dynamic analysis of all of the filling stages has not been conducted. Therefore, 1...

MicroRNAs (miRNAs) have been shown to play crucial roles in the regulation of plant development. In this study, high-throughput RNA-sequencing technology was used to identify novel miRNAs, and to reveal miRNAs expression patterns at different developmental stages during rice (Oryza sativa L.) grain filling. A total of 434 known miRNAs (380, 402, 390 and 392 at 5, 7, 12 and 17 days after fertili...

Breeding programs for increasing spikelet number in rice have resulted in compactness of the panicle, accompanied by poor grain filling in inferior spikelets. Although the inefficient utilization of assimilate has been indicated as responsible for this poor grain filling, the underlying cause remains elusive. The current study utilized the suppression subtractive hybridization technique to iden...

individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...

This study aims to clarify the effect of rice straw combined with inorganic fertilizer on grain-filling characteristics and yield formation common buckwheat (Fagopyrum esculentum Moench) provide a scientific basis for utilization fertilization in Guizhou Province.Common ‘Fengtian1’ was field-grown treated no (CK), normal (SF), full 20% reduction conventional (SH), 40% (SM), 80% inconventional (...
