Special Issue Information

Dear Colleagues,

Waterlogging is a critical challenge to global agriculture, adversely affecting crop productivity by disrupting root oxygen supply and overall plant growth. This Special Issue aims to address these challenges by exploring innovative agronomic strategies, molecular resistance mechanisms and physiological adaptations to enhance crop resilience to waterlogging.

The key areas of interest include agronomic practices that mitigate waterlogging effects, the role of fertilizers in supporting plant growth and recovery under and post-stress, and the use of plant growth regulators to promote crop resilience. Additionally, studies focusing on understanding the molecular mechanisms underlying crop resilience under waterlogging are highly encouraged. Research on plant physiology and metabolites, such as stomatal signaling and photosynthesis, and metabolic profiles are crucial for understanding how crops can adapt to waterlogged conditions.

We invite contributions that delve into these topics, offering insights into the molecular, physiological and agronomic mechanisms that underpin crop resilience to waterlogging. By fostering a comprehensive understanding of these processes, this Special Issue aims to offer insights into practical solutions and innovative approaches to ensure sustainable crop production in waterlogged areas. Submissions that explore related aspects and present novel findings are also welcome, contributing to a holistic approach to tackling waterlogging in agriculture.

Optimizing Nitrogen Supplementation: Timing Strategies to Mitigate Waterlogging Stress in Winter- and Spring-Type Canola

Canola is an important rotation crop in Australia’s high-rainfall zone (HRZ), where frequent waterlogging occurs. Due to its lack of aerenchyma, canola is more vulnerable to waterlogging. Recent studies have shown that nitrogen supplementation can benefit crop growth under waterlogging stress. However, limited reports have addressed the physiological responses and macronutrient changes in either winter or spring canola with strategically timed fertilizer applications. This study investigated the physiological and elemental responses of two canola genotypes to nitrogen application at different timings during waterlogging stress. By imposing waterlogging stress in pot-based trials for 21 days using spring-type (Dynatron) and winter-type (Nizza) canola, our results demonstrated that nitrogen application one week prior to the onset of waterlogging marginally improved soil plant analysis development (SPAD) values in the two types of canola, but only significantly enhanced stomatal conductance along with reduced photosynthetic efficiency in Dynatron at the end of waterlogging, indicating genotypic differences. Furthermore, applying fertilizer a week before waterlogging enhanced macronutrient accumulation in Dynatron, including phosphorus, potassium, magnesium, and calcium. In contrast, Nizza only exhibited a significant increase in magnesium accumulation. Fertilizer application had no effect on reducing Mn and Fe accumulation in canola, indicating that Mn and Fe toxicity, typically associated with soil waterlogging, was not a contributing factor in nitrogen-induced waterlogging alleviation. Collectively, our results demonstrated genotype-specific nutrient dynamics, which should be considered in nitrogen-induced waterlogging alleviation. Full article

Waterlogging is becoming a global issue, affecting crop growth and yield in low-lying rainfed areas. A DH line, TamF169, showing superior waterlogging tolerance, and its waterlogging-sensitive parent, Franklin, were used to conduct transcriptome analyses. The results showed that 2209 and 2578 differentially expressed genes (DEGs) in Franklin and 1997 and 1709 DEGs in TamF169 were detected by comparing gene expression levels under control and waterlogging after 4 and 8 days, respectively, with 392 and 257 DEGs being specific to TamF169 after 4 and 8 days under waterlogging, respectively. KEGG analysis showed that glycolysis/gluconeogenesis, the MAPK signaling pathway, plant hormone signaling, and galactose metabolism pathways were significantly enriched in the waterlogging-tolerant genotype TamF169 four days after waterlogging. The qPCR results were consistent with the transcriptome data, suggesting the reliability of the transcriptome sequencing. A total of 13 genes in the mapping region of a QTL for root cortical aerenchyma (RCA) showed different expression levels in Franklin or TamF169, and the potential candidate genes for RCA−QTL are discussed. This study offers valuable information on the mechanism of tolerance to waterlogging stress in the DH line TamF169 and provides the candidate genes for RCA−QTL. Full article
