Getting to the Root of a Root Problem
Science Signaling, 2014Nitrogen-starved rootlets send small peptides to the shoot to initiate compensatory uptake in other rootlets.

, 2008 Nonstationarity is certainly one of the most dominant and enduring characteristics of macroeconomic and financial time series. It therefore seems appropriate that this feature of the data be seriously addressed both in econometric methodology and in empirical practice. However, until recently this has not been the case.

INFERENCE IN LINEAR TIME SERIES MODELS WITH SOME UNIT ROOTS
, 1990This paper considers estimation and hypothesis testing in linear time series when some or all of the variables have (possibly multiple) unit roots. The motivating example is a vector autoregression with some unit roots in the companion matrix, which ...

A t one time, scientists thought that mountains and valleys arise because the earth is shrinking; all the wrinkles, folds, faults and other deformations in the planet's crust were likened to the crinkly skin of a drying apple. Then came the theory of plate tectonics, which revolutionized the earth sciences and gave researchers a more tenable framework ...

Roots shaping their microbiome: global hotspots for microbial activity.
Annual Review of Phytopathology, 2015Land plants interact with microbes primarily at roots. Despite the importance of root microbial communities for health and nutrient uptake, the current understanding of the complex plant-microbe interactions in the rhizosphere is still in its infancy ...

Decomposition of Root Tips, Fine Roots, and Coarse Roots
2020Decomposition of fine-root litter is much less studied than that of foliar litter although fine root litter is a major contributor to litter input to the forest soil. This chapter is devoted to decomposition of root tips and fine roots. Root litter decomposition may be studied using litter bags, through following remaining root mass in soil cores, or ...

Competition between roots and microorganisms for nitrogen: mechanisms and ecological relevance.
New Phytologist, 2013Demand of all living organisms on the same nutrients forms the basis for interspecific competition between plants and microorganisms in soils. This competition is especially strong in the rhizosphere.

Australian Dental Journal, 1986
Abstract— Over the past years a great deal of work has been done in the field of tooth root resorption but notwithstanding this, understanding of the subject has progressed very little. This paper reviews the subject and suggests ways of minimizing root resorption or perhaps even eliminating it.

S'appuyant sur les travaux de L. Febvre et D. Wotton, l'A. retrace l'historiographie des preuves et des persuasions qui ont contribue au debat sur l'incroyance et l'atheisme, depuis le spinozisme jusqu'au neorepublicanisme, et depuis le christianisme primitif jusqu'a l'heterodoxie ...
