From intercropping to monocropping: The effects of Pseudomonas strain to facilitate nutrient efficiency in peanut and soil.

As an oilseed crop, the yield and quality of peanuts are severely constrained by nutrient deficiencies, particularly in calcareous soils in northern China. Maize-peanut intercropping is an effective strategy to enhance mineral nutrient efficiency in peanuts via plant-microbe interaction, but the underlying mechanisms remain elusive. Here, we conducted experiments using a Pseudomonas strain (Pse.

Root exudate signals in plant-plant interactions.

Plant-to-plant signalling is a key mediator of interactions among plant species. Plants can perceive and respond to chemical cues emitted from their neighbours, altering survival and performance, impacting plant coexistence and community assembly. An increasing number of studies indicate root exudates as key players in plant-to-plant signalling.

Nematicidal Effect of Methyl Palmitate and Methyl Stearate against in Bananas.

Banana plants ( spp.) are susceptible to infection by many plant-parasitic nematodes, including . In this study, a mixed fermentation broth of chicken manure (CM) and cassava ethanol wastewater (CEW) was used to inhibit by reducing egg hatching and by having a lethal effect on second-stage juvenile nematodes (J2s).

From Leguminosae/Gramineae Intercropping Systems to See Benefits of Intercropping on Iron Nutrition.

To achieve sustainable development with a growing population while sustaining natural resources, a sustainable intensification of agriculture is necessary. Intercropping is useful for low-input/resource-limited agricultural systems. Iron (Fe) deficiency is a worldwide agricultural problem owing to the low solubility and bioavailability of Fe in alkaline and calcareous soils.

AhNRAMP1 Enhances Manganese and Zinc Uptake in Plants.

Manganese (Mn) and zinc (Zn) play essential roles in plants. Members of the natural resistance-associated macrophage protein (NRAMP) family transport divalent metal ions. In this research, the function of peanut ( L.

AhFRDL1-mediated citrate secretion contributes to adaptation to iron deficiency and aluminum stress in peanuts.

Although citrate transporters are involved in iron (Fe) translocation and aluminum (Al) tolerance in plants, to date none of them have been shown to confer both biological functions in plant species that utilize Fe-absorption Strategy I. In this study, we demonstrated that AhFRDL1, a citrate transporter gene from peanut (Arachis hypogaea) that is induced by both Fe-deficiency and Al-stress, participates in both root-to-shoot Fe translocation and Al tolerance. Expression of AhFRDL1 induced by Fe deficiency was located in the root stele, but under Al-stress expression was observed across the entire root-tip cross-section.

The Yellow Stripe-Like (YSL) Gene Functions in Internal Copper Transport in Peanut.

Copper (Cu) is involved in fundamental biological processes for plant growth and development. However, Cu excess is harmful to plants. Thus, Cu in plant tissues must be tightly regulated.

Comparative transcriptomic analysis of the roots of intercropped peanut and maize reveals novel insights into peanut iron nutrition.

Intercropping is a vital technology in resource-limited agricultural systems with low inputs. Peanut/maize intercropping enhances iron (Fe) nutrition in calcareous soil. In this study, the transcriptome of peanut and maize roots was analyzed by suppression subtractive hybridization (SSH) and microarray analysis separately.

Effects of Fe-deficient conditions on Fe uptake and utilization in P-efficient soybean.

Phosphorus (P)-efficient soybean (Glycine max) plants absorb and utilize P with high efficiency. To investigate the effects of iron (Fe)-deficient conditions on the absorption and utilization of Fe in P-efficient soybean plants, two soybean cultivars with different P efficiency, the 03-3 (P-efficient variety) and Bd-2 (P-inefficient variety), were used in this study. The two soybean cultivars were grown in nutrient solution containing Fe concentrations of 0 (Fe0), 20 (Fe20), 40 (Fe40), or 80 (Fe80) μM for 7 days.

[Citrus boron nutrient level and its impact factors in the Three Gorges Reservoir region of Chongqing, China].

To investigate the level of boron nutrient in citrus and its impact factors, a total of 954 citrus leaf samples and 302 soil samples were collected from representative orchards in the 12 main citrus production counties in the Three Gorges Reservoir region of Chongqing to determine the boron content in citrus leaves, as well as the relationships between leaf boron content with soil available boron content, soil pH value, cultivar, rootstock and the age of tree. Results indicated that the leaf samples from 41.6% orchards (< 35 mg x kg(-1)) and the soil samples from 89.

Exogenous spermine pretreatment confers tolerance to combined high-temperature and drought stress in trifoliate orange seedlings via modulation of antioxidative capacity and expression of stress-related genes.

Spermine (Spm) is thought to play an important role in drought or high-temperature (HT) tolerance. However, it is not clear whether Spm confers similar resistance in the presence of both drought and HT, which often occur simultaneously. In the present study, the trifoliate orange ( (L.
