Search for anions in molecular sources: C4H- detection in L1527 [PDF]

, 2007
We present the results of a search for the negative ion C4H- in various dark clouds, low mass star-forming regions and photon-dominated regions (PDRs). We have also searched for C6H-, C2H- and CN- in some of the sources.

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

PLANTS, PEOPLE, PLANET, EarlyView.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

The Altered Expression of microRNA408 Influences the Arabidopsis Response to Iron Deficiency

Frontiers in Plant Science, 2019
MicroRNAs contribute to the adaptation of plants to varying environmental conditions by affecting systemic mineral nutrient homeostasis. Copper and iron deficiencies antagonistically control the expression of Arabidopsis thaliana microRNA408 (miR408 ...

Connecting the dots: Network structure as a functional trait in arbuscular mycorrhizal fungi

PLANTS, PEOPLE, PLANET, EarlyView.
Soil health and sustainable land management are critical to addressing global challenges such as food security, climate resilience, and biodiversity loss. Arbuscular mycorrhizal (AM) fungi form underground networks that enhance plant nutrient uptake and improve soil structure, yet their functional diversity remains poorly understood, limiting their ...

Prospective of indigenous African wild food plants in alleviation of the severe iron deficiency anaemia in Sub‐Saharan Africa

PLANTS, PEOPLE, PLANET, EarlyView.
Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

Deregulated High Affinity Copper Transport Alters Iron Homeostasis in Arabidopsis

Frontiers in Plant Science, 2020
The present work describes the effects on iron homeostasis when copper transport was deregulated in Arabidopsis thaliana by overexpressing high affinity copper transporters COPT1 and COPT3 (COPTOE).

Far-Infrared detection of H2D+ toward Sgr B2 [PDF]

, 2007
We report on the first far-IR detection of H2D+, using the Infrared Space Observatory, in the line of sight toward Sgr B2 in the galactic center. The transition at 126.853 um connecting the ground level of o-H2D+, 1_1,1 with the the 2_1,2 level at 113 K,
