Isolation of three MiDi19-4 genes from mango, the ectopic expression of which confers early flowering and enhances stress tolerance in transgenic Arabidopsis
Three Di19-4 genes were identified in mango. Overexpression of MiDi19-4B in A. thaliana promoted earlier flowering and enhanced drought, salt, and ABA resistance.

Does drought stress intensify the allelopathy of invasive woody species Rhus typhina L.?
Drought stress intensified the allelopathy of Rhus typhina L. and Sapindus mukorossi Gaerten, and drought stress reinforced the allelopathy of S. mukorossi more significantly than R. typhina.

The mechanisms of rapid seed germination in Caragana species adapted to low mean annual precipitation
The rapid seed germination of Caragana species adapted to arid environments is closely related to their high seed coat permeability, mist absorption, high GA promotion, and reduced ABA inhibition.

Identification and functional characterization of three cytochrome P450 genes for the abietane diterpenoid biosynthesis in Isodon lophanthoides
We identify two ferruginol synthases and a 11-hydroxyferruginol synthase from a traditional Chinese medicinal herb Isodon lophanthoides and propose their involvement in two independent abietane diterpenoids biosy...

A first greenhouse application of bacteria-expressed and nanocarrier-delivered RNA pesticide for Myzus persicae control
There are two main limitations for sprayable RNA pesticide development: delivery efficiency and synthetic cost of double-stranded RNA (dsRNA). We previously constructed a nanocarrier-based transdermal dsRNA de...

Conserved and divergent evolution of the bZIP transcription factor in five diploid Gossypium species
495 bZIP members with 12 subfamilies were identified in the five diploid cottons. Segmental duplication events in cotton ancestor might have led to primary expansion of the cotton bZIP members.

Responses of radial growth of Picea crassifolia to climate change over three periods at different elevations in the Qilian Mountains, northwest China
Qinghai spruce at different elevations showed inconsistent growth trends and responses to climate change.

Complete chloroplast genomes of two medicinal Swertia species: the comparative evolutionary analysis of Swertia genus in the Gentianaceae family
The complete chloroplast genome of Swertia kouitchensis has been sequenced and assembled, compared with that of S. bimaculata to determine the evolutionary relationships among species of the Swertia in the Gentia...

Machine learning-based estimates of aboveground biomass of subalpine forests using Landsat 8 OLI and Sentinel-2B images in the Jiuzhaigou National Nature Reserve, Eastern Tibet Plateau
Accurate estimates of forest aboveground biomass (AGB) are critical for supporting strategies of ecosystem conservation and climate change mitigation. The Jiuzhaigou National Nature Reserve, located in Eastern...

Response of sap flow in Qinghai spruce (Picea crassifolia) to environmental variables in the Qilian Mountains of China
Vapor pressure deficit, soil water content, and daily maximum air temperature were the most important variables to affect sap flow.

Energy partitioning and evapotranspiration in a black locust plantation on the Yellow River Delta, China
Plantations of woody tree species play a crucial role in ecological security along coastal zones. Understanding energy partitioning and evapotranspiration can reveal land–atmosphere interaction processes. We i...

Open AccessResponse of density-related fine root production to soil and leaf traits in coniferous and broad-leaved plantations in the semiarid loess hilly region of China
Fine roots are the most active and functional component of root systems and play a significant role in the acquisition of soil resources. Density is an important structural factor in forest plantations but inf...

Open AccessResponses to defoliation of Robinia pseudoacacia L. and Sophora japonica L. are soil water condition dependent
Defoliation significantly affected biomass allocation of Robinia pseudoacacia L. and Sophora japonica L., but leaf physiology readjusted to control levels at the end of the experiment. Considering carbon or sink ...
