Fungos endofíticos associados a acículas de Pinus taeda [PDF]

Summa Phytopathologica, 2010
O presente trabalho objetivou estudar os fungos endofíticos em acículas de árvores jovens de Pinus taeda L. e avaliar o efeito da posição de coleta na árvore. As amostras foram coletadas em duas alturas (30-50 cm e 100-130 cm acima do solo) e nas quatro posições cardeais (norte, sul, leste e oeste), em plantas com 18 meses de idade, localizadas em ...

Comparative Study of the Effects of Shading Treatments on Photosynthetic Capacity, Chlorophyll Fluorescence, Chlorophyll Content, and Antioxidant Activities of Viburnum opulus and V. japonicum

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Viburnum opulus is recognized as a medicinal plant, whereas V. japonicum shows promise as an excellent ornamental species. This research aimed to explore their responses by cultivating under four graduated shading treatments (0%, 25%, 50%, and 75% shading).

Differences in Phenylpropanoid and Reactive Oxygen Species Genes Drive Plastic and Adaptive Responses to Drought Stress Between Douglas‐Fir Varieties and Hybrids

Plant Direct, Volume 10, Issue 3, March 2026.
ABSTRACT Warming climates bring significant challenges to the survival and growth of conifer species, yet the genomic basis of drought resistance is poorly understood. In this study, we used a common garden experiment to combine genomic, physiological and transcriptomic analysis to dissect plastic and adaptive responses to drought between Douglas‐fir ...

Insecticidal properties of Pinus taeda essential oil

Revista Ceres
This study aimed to evaluate the yield of essential oil extracted from different sample and pH compositions, as well as the insecticidal potential of Pinus taeda essential oil. For this, samples composed only of needle and composed of needle and branches were kept in solvent water at different pH (3, 4, 5 and 6). Subsequently, the oils extracted in the

Soil carbon, nitrogen, and biological activity as affected by land use and grassland management across North Carolina

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Undisturbed land uses have the potential to enhance soil organic matter, but how and to what extent this occurs on private farms remains relatively unexplored. A cross‐sectional study of perennial grasslands and farm woodlots was undertaken across North Carolina to investigate stocks of soil organic C, total soil N, and soil‐test biological ...

Broad-specificity quinate (shikimate) dehydrogenasefrom Pinus taeda needles

Plant Physiology and Biochemistry, 2000
Abstract Two proteins having quinate dehydrogenase (QDH, quinate:NAD(P)+-oxidoreductase, EC 1.1.1.24) and shikimate dehydrogenase (SDH, shikimate:NADP+-oxidoreductase, EC 1.1.1.25) activities were purified about 3 000-fold from young loblolly pine (Pinus taeda L.) needles. A combination of ammonium sulfate solubilization, and chromatographies on DEAE-

Neutral effects of low‐intensity dog training on northern bobwhite vital rates

Wildlife Biology, Volume 2026, Issue 2, March 2026.
Indirect effects of hunting can lead to changes in population dynamics, which can be caused by trait‐mediated effects such as, but not limited to, changes in behavior, reproduction, and physiological responses. Our understanding of the effects of activities associated with hunting such as dog training may incur trait‐mediated effects, and ultimately ...

Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

New Phytologist, Volume 249, Issue 6, Page 3060-3071, March 2026.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.
