TL;DR: In this paper, the effect of N application rate on post-silking N uptake, vegetative N remobilization, GY, and GNC of two high-yielding maize hybrids, ZD958 and XY335, was investigated.

Within-Leaf Nitrogen Allocation in Adaptation to Low Nitrogen Supply in Maize during Grain-Filling Stage
TL;DR: It is concluded that optimization of N allocation within leaves is a key adaptive mechanism to maximize Pn and crop productivity when N is limited during the grain-filling stage in maize under low-N conditions.
Genetic improvement of root growth increases maize yield via enhanced post-silking nitrogen uptake
TL;DR: This study provides a successful case that increasing root size via genetic manipulation contributes directly to efficient N-uptake and higher yield under both adequate and inadequate N- supply and different weather conditions.

Dynamic change of mineral nutrient content in different plant organs during the grain filling stage in maize grown under contrasting nitrogen supply
TL;DR: In this paper, the authors investigated the role of the retranslocation of nutrients from vegetative organs to grain to increase the nutrient concentration of maize grain and general nutrient use efficiency.

A RNA-Seq Analysis of the Response of Photosynthetic System to Low Nitrogen Supply in Maize Leaf.
TL;DR: It was found that low nitrogen supply down-regulated the expression of genes involved in photosystem I (PSI) and photosystem II (PSII), and this could lead to the development of new tools to make precise nitrogen fertilizer recommendations and select nitrogen-efficient genotypes.
