Fern mycorrhizae do not respond to fertilization in a tropical montane forest [0.03%]
热带山地森林中的肾蕨菌根对施肥无任何响应

Ferns are known to have a lower incidence of mycorrhization than angiosperms. It has been suggested that this results from carbon being more limiting to fern growth than nutrient availability, but this assertion has not been tested yet. In ...
Determination of abundance and symbiotic effectiveness of native rhizobia nodulating soybean and other legumes in Rwanda [0.03%]
卢旺达根瘤菌的丰度和共生有效性的测定及与其他豆类结瘤大豆的关系

Rhizobia diversity in the rhizosphere is one of the key promoters of biological nitrogen fixation between host legumes and microsymbionts, although related complex interaction may depend on various factors. This research was intended to ass...
Nonpathogenic leaf-colonizing bacteria elicit pathogen-like responses in a colonization density-dependent manner [0.03%]
非致病性的叶部寄生细菌以定植密度依赖性方式引发类似病原体的反应

Leaves are colonized by a complex mix of microbes, termed the leaf microbiota. Even though the leaf microbiota is increasingly recognized as an integral part of plant life and health, our understanding of its interactions with the plant hos...
Historical tree phenology data reveal the seasonal rhythms of the Congo Basin rainforest [0.03%]
历史树木物候数据揭示刚果盆地雨林的季节性规律

Tropical forest phenology directly affects regional carbon cycles, but the relation between species-specific and whole-canopy phenology remains largely uncharacterized. We present a unique analysis of historical tropical tree phenology coll...
Seed mucilage in temperate grassland species is unrelated to moisture requirements [0.03%]
温带草甸植物的种子粘液与水分需求无关

Myxospermy, the release of seed mucilage upon hydration, plays multiple roles in seed biology. Here, we explore whether seed mucilage occurs in a suite of temperate grassland species to test if the prevalence of species producing seed mucil...
Associations between shade tolerance and wood specific gravity for conifers in contrast to angiosperm trees: Foundations of the conifer fitness-enhancing shade tolerance hypothesis [0.03%]
针叶树与被子树种间耐阴性与木材密度的关系：针叶树耐阴适应性假说的基础

For decades, researchers have held that wood specific gravity was an indicator or surrogate for both shade tolerance and successional status. However, recent research in dry tropical forests has shown very different associations regarding w...
Inoculation of black turtle beans (Phaseolus vulgaris) with mycorrhizal fungi increases the nutritional quality of seeds [0.03%]
黑龟豆（Phaseolus vulgaris）与丛生菌根真菌的接种提高了种子的营养价值

The use of arbuscular mycorrhizal fungi (AMF) as biofertilizers has proven successful in boosting the yield and nutritional quality of a variety of crops. AMF associate with plant roots and exchange soil nutrients for photosynthetically der...
Establishment from seed is more important for exotic than for native plant species [0.03%]
种子萌发对于外来植物物种比本土植物物种更重要

Climate change has initiated movement of both native and non-native (exotic) species across the landscape. Exotic species are hypothesized to establish from seed more readily than comparable native species. We tested the hypothesis that see...

Subarctic ecosystems are exposed to elevated temperatures and increased cloudiness in a changing climate with potentially important effects on vegetation structure, composition, and ecosystem functioning. We investigated the individual and ...
Natural genetic variation and negative density effects in plant-nematode interactions [0.03%]
植物-线虫相互作用中的自然遗传变异和负密度效应
Maisara Mukhaimar,Marina Pfalz,Jacqui Shykoff et al.
Maisara Mukhaimar et al.
Arabidopsis thaliana is a suitable host for phytoparasitic nematodes of the genus Meloidogyne. Successful nematode infection leads to the formation of root galls. We tested for natural genetic variation and inoculation density effects on ne...
