Transcriptome analysis of genes involved in flower and leaf color of Oncidium by RNA-seq

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2023
Oncidium, an important tropical orchid, has high ornamental value due to its specific color and occupies a significant market position for the worldwide flower. Transcriptome analysis of flower and leaf color formation provides new sources for producing

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]

open access: yes, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

Grazing alters species relative abundance by affecting plant functional traits in a Tibetan subalpine meadow

open access: yesEcology and Evolution, 2021
Domestic livestock grazing has caused dramatic changes in plant community composition across the globe. However, the response of plant species abundance in communities subject to grazing has not often been investigated through a functional lens ...

Genome-wide analysis of tandem duplicated genes and their expression under salt stress in seashore paspalum

open access: yesFrontiers in Plant Science, 2022
Seashore paspalum (Paspalum vaginatum) is a halophytic, warm-season grass which is closely related to various grain crops. Gene duplication plays an important role in plant evolution, conferring significant plant adaptation at the genomic level. Here, we

Why do some tropical forests have so many kinds of trees?

open access: yes, 2004
Understanding why there are so many kinds of tropical trees requires learning, not only how tree species coexist, but what factors drive tree speciation and what governs a tree clade’s diversification rate.

Genetic rescue of remnant tropical trees by an alien pollinator [PDF]

open access: yes, 2001
Habitat fragmentation is thought to lower the viability of tropical trees by disrupting their mutualisms with native pollinators. However, in this study, Dinizia excelsa (Fabaceae), a canopy-emergent tree, was found to thrive in Amazonian pastures and ...

Genetic Divergence between Two Sympatric Ecotypes of Phalaenopsis pulcherrima on Hainan Island

open access: yesDiversity, 2021
Ecotypes are the result of ecological differentiation at the early stages of speciation. Adaptation to soil conditions offers arguably the best examples of local adaptation in plants.

Soil nematode community assembly in a primary tropical lowland rainforest

open access: yesFrontiers in Ecology and Evolution, 2022
More than half of the world's tropical lowland rainforests have been lost due to conversion to agricultural land (such as rubber plantations). Thus, ecological restoration in degraded tropical lowland rainforests is crucial. The first step to restoration
