Effects of salt and low light intensity during the vegetative stage on susceptibility of rice to male sterility induced by chilling stress during the reproductive stage

Plant Production Science, 2016
We tested whether exposing rice plants to abiotic stress (salt or shade) during vegetative growth affects the chilling tolerance of reproductive organs, which is one of the most important traits for rice growing in a cool climate; we used two rice ...

Coupled Above‐ and Belowground Ecosystem Stability Worldwide

Advanced Science, EarlyView.
Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

Solanum elaeagnifolium Invasiveness under Semi-Arid Environmental Conditions in Tunisia

Earth, 2022
Solanum elaeagnifolium, one of the world’s most widespread invasive weeds, thrives in the regions of Tunisia with a semi-arid climate. An enhanced understanding of its biological traits could be useful for its management.

POLYCULTIVATION AND AGROFORESTRY SYSTEMS IMPACT THE VEGETATIVE GROWTH OF VEGETABLES

REVISTA DE AGRICULTURA NEOTROPICAL, 2023
This study was carried out with the aim of evaluating the performance of vegetable production in different agrobiodiverse cropping systems, comparing two successive agroforestry systems (SAFS) with a non-tree vegetables polyculture. The experiment was conducted in an experimental design in randomized blocks, with three treatments and four replications.

Spores of Clostridium engineered for clinical efficacy and safety cause regression and cure of tumors in vivo. [PDF]

, 2014
Spores of some species of the strictly anaerobic bacteria Clostridium naturally target and partially lyse the hypoxic cores of tumors, which tend to be refractory to conventional therapies. The anti-tumor effect can be augmented by engineering strains to

The Transcription Factor FgSge1 Harnesses the SAGA Complex to Activate Mycotoxin Biosynthesis and Fungal Virulence

Advanced Science, EarlyView.
This study reveals the molecular mechanism by which the transcription factor FgSge1 regulates mycotoxin biosynthesis and virulence in Fusarium graminearum. FgSge1 binds to the TAARGTTT cis‐element, enabling self‐activation. It recruits the SAGA complex, promotes histone acetylation, and facilitates jet‐like chromatin remodeling, thereby activating ...

Prevalent vegetation growth enhancement in urban environment [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Cities experiencing elevated temperature (i.e., urban “heat island” warming), CO 2 , and nitrogen deposition decades ahead of the projected average global change are regarded as the “harbingers” of the future global change.

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

Advanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...
