TaSnRK3.23B, a CBL-interacting protein kinase of wheat, confers drought stress tolerance by promoting ROS scavenging in Arabidopsis.

Background: Sucrose non-fermenting-1-related protein kinases (SnRKs) have been implicated in plant growth and stress responses. Although SnRK3.23 is known to be involved in drought stress, the underlying mechanism of resistance differs between Arabidopsis and rice, and little is known about its function in wheat.

Drought and High Temperatures Impact the Plant-Pollinator Interactions in .

As a result of climate change, temperate regions are facing the simultaneous increase in water and heat stress. These changes may affect the interactions between plants and pollinators, which will have an impact on entomophilous crop yields. Here, we investigated the consequences of high temperatures and water stress on plant growth, floral biology, flower-reward production, and insect visitation of five varieties of common buckwheat (), an entomophilous crop of growing interest for sustainable agriculture.

Mapping and Validation of Quantitative Trait Loci on Yield-Related Traits Using Bi-Parental Recombinant Inbred Lines and Reciprocal Single-Segment Substitution Lines in Rice ( L.).

Yield-related traits have higher heritability and lower genotype-by-environment interaction, making them more suitable for genetic studies in comparison with the yield per se. Different populations have been developed and employed in QTL mapping; however, the use of reciprocal SSSLs is limited. In this study, three kinds of bi-parental populations were used to investigate the stable and novel QTLs on six yield-related traits, i.

Identification of Rht1 for plant height reduction in two wheat mutants and the effects on yield components.

Plant height determines lodging resistance and is closely linked to yield stability in wheat. In this study, we identified two semi-dwarf wheat mutants, designated je0370 and je0344, using the winter wheat cultivar Jing411 as the wild type (WT). Field experiments revealed that the plant height of these two mutants was significantly lower than that of the WT.

Exogenous melatonin enhances heat tolerance in buckwheat seedlings by modulating physiological response mechanisms.

Melatonin (MT) serves as a potent antioxidant in plant organisms, bolstering their resilience to temperature stress. In this study, the impact of MT on various buckwheat varieties under high-temperature stress conditions (40 °C) was investigated. Specifically, five buckwheat seedling varieties, comprising three sweet buckwheat variants (Fagopyrum esculentum) and two bitter buckwheat types (Fagopyrum tataricum), were subjected to foliar sprays of melatonin at concentrations of 50, 100 and 200 μM, with water at 25 °C employed as a control.

Soybean2035: A decadal vision for soybean functional genomics and breeding.

Soybean, the fourth most important crop in the world, uniquely serves as a source of both plant oil and plant protein for the world's food and animal feed. Although soybean production has increased approximately 13-fold over the past 60 years, the continually growing global population necessitates further increases in soybean production. In the past, especially in the last decade, significant progress has been made in both functional genomics and molecular breeding.

Optimization of γ-Aminobutyric Acid Production in Brown Rice via Prolonged Seed Priming.

Germinated whole seeds possess elevated levels of bioactive nutrients; however, their application is hindered by several constraints. The germination process is typically time-consuming, and germinated seeds present challenges in terms of storage and transportation compared to dry seeds. This study introduces a novel processing method for rice, termed prolonged priming (PLP), aiming to combine the benefits of germinated and dry seeds.

Pollen Morphological Characteristics of 46 Germplasm Resources of and Its Taxonomic Implications.

To elucidate the morphological diversity and genetic characteristics of the pollen of species, this study utilized a total of 46 samples encompassing six species and one variety of . Scanning electron microscopy (SEM) was employed to examine the morphological traits of the pollen and to analyze the evolutionary patterns and genetic relationships among species. The results indicate that the pollen grains of the 46 germplasm are uniformly characterized as monads, heteropolar, bilaterally symmetrical, atreme, and possess a mono-sulcus.

Advances in Research on Southern Corn Rust, a Devasting Fungal Disease.

Southern corn rust (SCR), caused by the obligate biotrophic fungus Underw., represents one of the most devastating threats to maize production, potentially resulting in yield losses exceeding 50%. Due to global climate change and cropping practices, epiphytotics of SCR have been increasingly reported, and are progressively spreading from tropical and subtropical maize growing areas to higher latitude areas.

Genome-Wide Identification of the Trihelix Transcription Factor Family and Functional Analysis of in Maize.

The trihelix transcription factor, which is a plant-specific family, play a critical role in plant growth and development and stress responses. Drought is the main limiting factor affecting yield of maize (). However, the identification and characterization of this gene family in maize and its biological functions in response to drought stress have not been reported.

Overexpression of AtbZIP69 in transgenic wheat confers tolerance to nitrogen and drought stress.

AtbZIP69 overexpression in wheat significantly enhanced drought and low nitrogen tolerance by modulating ABA synthesis, antioxidant activity, nitrogen allocation, and transporter gene expression, boosting yield. In this study, we generated wheat plants with improved low nitrogen (LN) and drought tolerance by introducing AtbZIP69, a gene encoding a basic leucine zipper domain transcription factor, into the wheat cultivar Shi 4056. AtbZIP69 localized to the nucleus and activated transcription.
