Nitrogen uptake, assimilation and remobilization in plants: challenges for sustainable and productive agriculture

TL;DR: The nitrogen (N) utilization efficiency in hydroponically grown durum wheat was dissected during nitrate depletion at post-flowering stage and tissue N concentration was 50% and 80% less important in leaves and culms, respectively, but similar in grains of N-deficient plants compared with control ones.

TL;DR: In this article , two experiments were conducted at the Multipurpose Crop Nursery Research fields of the Akenten Appiah-Menka University of Skill Training and Entrepreneurial Development (AAMUSTED), Mampong-Ashanti during the 2018 major (March-July) and minor (September-December) seasons to assess the effect of organic and inorganic fertilizers and their combinations on the growth and yield of carrot.

TL;DR: Low N resorption efficiency during senescence of P. polyphylla results from a sharp decrease in N remobilization enzyme activity, which is mainly responsible for the decline in N content, amino acids, and N-remobilization enzymes.

TL;DR: Yoshida, Shouichi as discussed by the authors, et al. 1981.Fundamentals of rice crop science, report,Laguna, PhilippinesInternational Rice Research Institute (IRI),

TL;DR: The positional cloning of Gpc-B1, a wheat quantitative trait locus associated with increased grain protein, zinc, and iron content, is reported here, and reduction in RNA levels of the multiple NAM homologs by RNA interference delayed senescence by more than 3 weeks and reduced wheat grain protein and zinc content.

TL;DR: These studies uncover surprisingly pivotal roles of KIN10/11 in linking stress, sugar and developmental signals to globally regulate plant metabolism, energy balance, growth and survival.

TL;DR: Important progress has been made in identifying transport and regulatory mechanisms for macronutrients and the mechanisms of uptake and distribution and the main physiological roles of each nutrient will be discussed.
