Kaempferol drives genotype-specific microbiota Bacillaceae to enhance nitrogen acquisition in rapeseed.

Introduction: Host genotype is a key driver in shaping plant microbiome in response to dynamic changes in soil nitrogen (N) availability. However, the effects of rapeseed (Brassica napus) genotypes with different N use efficiency characteristics on microbiome assembly, as well as the underlying plant-microbe interaction mechanisms, remain poorly understood.

Objectives: This study aims to: (1) assess microbial assembly differences between N-use efficient and inefficient genotypes; (2) identify specific microbiota associated with plant N acquisition; and (3) reveal the molecular mechanisms driving plant-microbe interactions.

Mitigating Metal Toxicity in Plants Using Nanoparticles: Mechanisms and Implications for Sustainable Agriculture.

Conventional agriculture's reliance on chemical inputs poses risks to human health and the environment.

This review highlights how NPs mitigate metal toxicity and soil acidification by enhancing nutrient delivery and reducing phytotoxicity.

Arsenite transporter OsNIP3;5 modulates phosphate starvation responses via regulating arsenite translocation in rice.

The plants inevitably absorb toxic arsenate [As(V)] through phosphate (Pi) transporters (PTs) in As-contaminated soils due to the structural similarity between phosphate and arsenate As(V). Plants suppress PT's expression to reduce As(V) uptake when As accumulates in the cytosol. However, how plants maintain efficient Pi uptake under As(V) stress conditions remains unknown.

Hydrogen Peroxide Positively Regulates Phosphate Starvation Responses in Rice.

Phosphorus is an essential macronutrient for plant growth and development. Under phosphate (Pi) starvation conditions, plants activate a series of adaptive responses, among which reactive oxygen species (ROS) accumulation in root tissues represents a notable yet poorly characterized phenomenon. This study investigated the regulatory role of hydrogen peroxide (HO) in rice adaptation to Pi deficiency through pharmacological intervention using potassium iodide (KI), a specific HO scavenger.

OsMYB67 Knockout Promotes Rice Heading and Yield by Facilitating Copper Distribution in Panicles.

Copper (Cu) is an essential micronutrient required for rice flowering and seed setting. Here, we identified that Cu-induced R2R3-MYB transcription factor, OsMYB67, acts as a negative regulator that controls rice heading and yield production by affecting Cu distribution in panicles. OsMYB67 was constitutively expressed, with the highest expression in the roots.

Integrated analysis of physiological and metabolic data uncovers essential dynamic mechanisms involved in the maturation of cigar tobacco leaves.

The quality of cigar tobacco leaves is profoundly affected by the timing of their harvest, with both early and late collections resulting in inferior characteristics. While the relationship between maturity and physiological metabolic processes is acknowledged, a comprehensive understanding of the physiological behavior of cigar leaves harvested at different stages remains elusive. This research investigated the physiological and metabolomic profiles of the cigar tobacco variety CX-014, grown in Danjiangkou City, Hubei Province, with leaves sampled at 35 (T1), 42 (T2), 49 (T3), and 56 (T4) days post-inflorescence removal.

The BnamiR827-BnaA09.NLA1-BnaPHT1 module regulates phosphate homeostasis, pollen viability, and seed yield in Brassica napus.

Phosphorus (P) is an essential macronutrient for the growth and yield of crops. However, there is limited understanding of the regulatory mechanisms of phosphate (Pi) homeostasis, and its impact on growth, development, and yield-related traits in Brassica napus. Here, we identified four NITROGEN LIMITATION ADAPTATION1 (BnaNLA1) genes in B.

Partial replacement by ammonium nutrition enhances Brassica napus growth by promoting root development, photosynthesis, and nitrogen metabolism.

Nitrogen (N) is crucial for plant growth, available primarily as nitrate (NO) and ammonium (NH). However, its presence in soil is often limited, necessitating strategies to augment N availability. This study delves into the enigmatic interplay between NO and NH in fostering the growth of Brassica napus, an important oil crop worldwide.

Transcription factor AtNAC002 positively regulates Cu toxicity tolerance in Arabidopsis thaliana.

Copper (Cu) is an essential micronutrient for plant growth and development, but environmental Cu pollution has become increasingly severe, adversely affecting both ecosystems and crop productivity. In this study, we identified the AtNAC002 gene as a positive regulator of Cu toxicity in Arabidopsis thaliana. We found that AtNAC002 expression was induced by Cu excess, and the atnac002 mutant was Cu-sensitive, accumulating more Cu than the wild-type.

Corrigendum: Drought-induced adaptive and ameliorative strategies in plants [Chemosphere 364 (2024) 143134].

Drought stress (DS) is a hazardous abiotic prerequisite that is becoming increasingly severe around the world. As a result, new management measures to reduce the negative effects of DS are desperately needed to ensure improved agricultural productivity. This review focuses primarily on various DS mitigation strategies that can be utilized to overcome DS.

Vacuolar Pi transporters (VPTs) have recently been identified as important regulators of cellular Pi status in and . In the oil crop , and are two homologs of , the vacuolar Pi influx transporter in . Here, we show that Pi deficiency induces the transcription of both homologs of genes in leaves.

Acid phosphatase involved in phosphate homeostasis in Brassica napus and the functional analysis of BnaPAP10s.

Purple acid phosphatases (PAPs) are involved in activating the rhizosphere's organic phosphorus (P) and promoting P recycling during plant development, especially under the long-term P deficiency conditions in acid soil. However, the function of BnaPAPs in response to P deficiency stress in Brassica napus has rarely been explored. In this study, we found that the acid phosphatase activities (APA) of rapeseed shoot and root increased under P deficienct conditions.

Trehalose-6-phosphate synthase 8 increases photosynthesis and seed yield in Brassica napus.

Trehalose-6-phosphate (T6P) functions as a vital proxy for assessing carbohydrate status in plants. While class II T6P synthases (TPS) do not exhibit TPS activity, they are believed to play pivotal regulatory roles in trehalose metabolism. However, their precise functions in carbon metabolism and crop yield have remained largely unknown.

Nitrate alleviates ammonium toxicity in Brassica napus by coordinating rhizosphere and cell pH and ammonium assimilation.

In natural and agricultural situations, ammonium ( ) is a preferred nitrogen (N) source for plants, but excessive amounts can be hazardous to them, known as toxicity.

A critical review of plant adaptation to environmental boron stress: Uptake, utilization, and interplay with other abiotic and biotic factors.

Boron (B) is an indispensable mineral nutrient for plants and is primarily taken up by roots mainly in the form of boric acid (HBO). Recently, research shows that B has a significant impact on plant growth and productivity due to its narrow range between deficiency and toxicity. Fertilization and other procedures to address B stress (deficiency and toxicity) in soils are generally expensive and time-consuming.
