Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Cell Signaling in Plants

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Microbe-Plant Interactions

Microbe-Plant Interactions

Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Summary

Low nitrogen (LN) enhances rice resistance to brown planthopper (BPH) by increasing defense compounds and reducing growth. The abscisic acid (ABA) pathway is crucial for this LN-mediated resistance in rice plants.

Area of Science:

Plant Science
Agronomy
Entomology

Background:

Nitrogen levels critically influence rice defense against pests like the brown planthopper (BPH).
Mechanisms of nitrogen-mediated BPH resistance in rice are not fully understood.

Purpose of the Study:

To elucidate the molecular and biochemical mechanisms by which nitrogen levels affect rice resistance to BPH.
To investigate the role of plant defense compounds and signaling pathways in this interaction.

Main Methods:

Comparative analysis of rice plants under low (LN), medium (MN), and high (HN) nitrogen conditions.
Biochemical assays for defense compounds (ABA, SA, cell wall components, flavonoids, phenolamides).
Transcriptome analysis and genetic manipulation of signaling pathways (ABA and SA).

Main Results:

Low nitrogen suppressed rice growth but significantly enhanced resistance to BPH.
LN plants showed increased abscisic acid (ABA), salicylic acid (SA), cell wall components, and flavonoids, with decreased phenolamides.
Impairing the ABA signaling pathway abolished LN-induced defense compound accumulation and BPH resistance.

Conclusions:

Low nitrogen enhances rice resistance to BPH through an ABA-dependent pathway.
Reduced relative water content and amino acid concentrations under LN also contribute to BPH resistance.
This study clarifies the role of ABA in nitrogen-mediated plant defense against insect pests.
