Histopathological evaluation of root canal filling materials for primary teeth [PDF]

, 2010
This study aimed to assess the response of apical and periapical tissues of dogs¿ teeth after root canal filling with different materials. Forty roots from dogs¿ premolars were prepared biomechanically and assigned to 4 groups filled with: Group I ...

Biomass and morphology of fine roots of sugi (Cryptomeria japonica) after three years of nitrogen fertilization

Frontiers in Plant Science, 2013
Increasing nitrogen (N) deposition may affect carbon and nutrient dynamics in forest ecosystems. To better understand the effects of N deposition, we need to improve our knowledge of N effects on fine roots (roots < 2 mm in diameter), as they are a ...

Comparison of Leaf and Fine Root Traits Between Annuals and Perennials, Implicating the Mechanism of Species Changes in Desertified Grasslands

Frontiers in Plant Science, 2022
Annual species show traits, such as shortleaf lifetimes, higher specific leaf area, and leaf nutrient concentrations, that provided a more rapid resource acquisition compared to perennials.

Intraspecific Fine-Root Trait-Environment Relationships across Interior Douglas-Fir Forests of Western Canada

Plants, 2019
Variation in resource acquisition strategies enables plants to adapt to different environments and may partly determine their responses to climate change. However, little is known about how belowground plant traits vary across climate and soil gradients.

Anaerobic induction of alanine aminotransferase in barley root tissue [PDF]

, 1989
Alanine aminotransferase, otherwise called glutamate-pyruvate aminotransferase (GPT), activity increases up to fourfold during several days of anaerobic induction in barley (Hordeum vulgare L.) roots, reaching a maximum activity of 13 intemational units ...

The promoter from SlREO, a highly-expressed, root-specific Solanum lycopersicum gene, directs expression to cortex of mature roots [PDF]

, 2008
Root-specific promoters are valuable tools for targeting transgene expression, but many of those already described have limitations to their general applicability.

Coordinated variation in root and leaf functional traits of Hippophae rhamnoides treated at different stump heights in feldspathic sandstone areas of Inner Mongolia

Frontiers in Plant Science, 2023
This study was aimed to clarify the effects of stumping on root and leaf traits as well as the tradeoffs and synergies of decaying Hippophae rhamnoides in feldspathic sandstone areas, and to select the optimal stump height that contributed to the ...

Root respiration and other four classical root traits

, 2020
This dataset is relevant to species specific root respiration and other four classical root traits (root N concentration, root diameter, root tissue density and specific root length).We aim to explore the relationships between root respiration and other ...

Pathogenicity of the root-knot nematode Meloidogyne javanica on potato [PDF]

, 2005
Host–parasite relationships and pathogenicity of Meloidogyne javanica on potatoes (newly recorded from Malta) were studied under glasshouse and natural conditions. Potato cvs Cara and Spunta showed a typical susceptible reaction to M. javanica under
