Nutrient Sensing in Plant Meristems

Plant Molecular Biology, 2006
Plants need nutrient to grow and plant cells need nutrient to divide. The meristems are the factories and cells that are left behind will expand and differentiate. However, meristems are not simple homogenous entities; cells in different parts of the meristem do different things. Positional cues operate that can fate cells into different tissue domains.

Autophagy and Nutrients Management in Plants [PDF]

Cells, 2019
Nutrient recycling and mobilization from organ to organ all along the plant lifespan is essential for plant survival under changing environments. Nutrient remobilization to the seeds is also essential for good seed production. In this review, we summarize the recent advances made to understand how plants manage nutrient remobilization from senescing ...

Nitrogen Use Efficiency in Maize over Sixteen Years of Unbalanced Fertilization with Nitrogen and Potassium

Agriculture
Adequate fertilization with nitrogen (N) and potassium (K) is essential to sustain crop productivity and minimize nitrogen losses to the environment. However, the increasing imbalance in fertilizer use in Poland, with low potassium inputs, may impair ...

Eutrophication [PDF]

, 2013
Aquatic plants need two essential nutrients for growth: phosphorus and nitrogen. They receive these nutrients through a process known as eutrophication, in which water bodies accumulate plant nutrients.

Plant invasion is associated with higher plant–soil nutrient concentrations in nutrient‐poor environments [PDF]

Global Change Biology, 2016
AbstractPlant invasion is an emerging driver of global change worldwide. We aimed to disentangle its impacts on plant–soil nutrient concentrations. We conducted a meta‐analysis of 215 peer‐reviewed articles and 1233 observations. Invasive plant species had globally higher N and P concentrations in photosynthetic tissues but not in foliar litter, in ...

Nitrogen and sulphur management: challenges for organic sources in temperate agricultural systems [PDF]

, 2005
A current global trend towards intensification or specialization of agricultural enterprises has been accompanied by increasing public awareness of associated environmental consequences. Air and water pollution from losses of nutrients, such as nitrogen (

Investigating the effect of belowground microbial volatiles on plant nutrient status: perspective and limitations

Journal of Plant Interactions, 2020
Volatile organic compounds displayed biological activities on a wide range of organisms, including plants and microbes. Investigating their role in the plant-microbe interaction processes occurring in the soil is challenging.

Food for thought: how nutrients regulate root system architecture [PDF]

, 2017
The spatial arrangement of the plant root system (root system architecture, RSA) is very sensitive to edaphic and endogenous signals that report on the nutrient status of soil and plant.
