TLDR
It is suggested that SRL can be used successfully as an indicator of nutrient availability to trees in experimental conditions after meta-analyses showed that S RL decreased significantly under fertilization and Al-stress and responded negatively to reduced light, elevated temperature and CO2.Abstract:
Specific root length (SRL, m g(-1)) is probably the most frequently measured morphological parameter of fine roots. It is believed to characterize economic aspects of the root system and to be indi ...read more

Proteomic Analyses Provide Novel Insights into Plant Growth and Ginsenoside Biosynthesis in Forest Cultivated Panax ginseng (F.Ginseng)
TL;DR: This study represents the first characterization of the proteome of F. Ginseng during development and provides new insights into the metabolism and accumulation of ginsenosides.

How tree roots respond to drought
TL;DR: Current knowledge about responses of tree roots to drought supports the view that tree roots are well equipped to withstand drought situations and maintain morphological and physiological functions as long as possible.

Are the rates of photosynthesis stimulated by the carbon sink strength of rhizobial and arbuscular mycorrhizal symbioses
Glaciela Kaschuk,Glaciela Kaschuk,Thomas W. Kuyper,Peter A. Leffelaar,Mariangela Hungria,Ken E. Giller +5 more
TL;DR: The inoculation of legumes with rhizobia and/or AM fungi, which resulted in sink stimulation of photosynthesis, improved the photosynthetic nutrient use efficiency and the proportion of seed yield in relation to the total plant biomass (harvest index).

A glance into aluminum toxicity and resistance in plants.
TL;DR: This review aims to give an up-to-date glance into current developments in the field of Al toxicity and resistance in plants, also providing sufficient background information for non-specialists in aluminum research.

Kramer,Kate Lajtha,J. LeMoine,Mary E. Martin,William H. McDowell,Rakesh Minocha,Jesse Sadowsky,Pamela H. Templer,Kyle Wickings +19 more
TL;DR: In this paper, the authors examine the contribution of trees versus soil to total ecosystem carbon storage in a temperate forest and investigate the mechanisms by which soils accumulate carbon in response to two decades of elevated nitrogen inputs.

A meta‐analysis of mycorrhizal responses to nitrogen, phosphorus, and atmospheric CO2 in field studies
TL;DR: It is suggested that global standing stocks of mycorrhizal fungi may increase substantially under elevated CO2 but decline moderately under P additions, and effects of N deposition may be difficult to predict for individual ecosystems, with a slightly negative influence overall.

Fine root architecture of nine north american trees
Kurt S. Pregitzer,Jared L. DeForest,Andrew J. Burton,Michael F. Allen,Roger W. Ruess,Ronald L. Hendrick +5 more
TL;DR: These findings run contrary to the common idea that all roots of a given size class function the same way and that a common size class for fine roots works well for all species.

Building roots in a changing environment: implications for root longevity
TL;DR: Using an efficiency model, it is shown that reduced tissue Nconcentration and reduced root maintenance respiration, both of which are predicted to result from elevated CO2, should lead to slightly longer root life spans.
