Drought poses a significant challenge to global wheat production, and the application of exogenous phytohormones offers a convenient approach to enhancing drought tolerance of wheat. However, little is known about the molecular mechanism by which strigolactones (SLs), newly discovered phytohormones, alleviate drought stress in wheat. Therefore, this study is aimed at elucidating the physiological and molecular mechanisms operating in wheat and gaining insights into the specific role of SLs in ameliorating responses to the stress.

Exogenous strigolactones (SLs, GR24) are widely used to alleviate drought stress in wheat. The physiological and biochemical mechanisms via which SLs help overcome drought stress in wheat shoots have been reported; however, the mechanisms in wheat roots are unclear. The present study explored the effects of the exogenous application of SLs on wheat roots' growth and molecular responses under drought stress using physiological analysis and RNA-seq.

Purpose: Evaluating face attractiveness is a core aspect of face perception, which plays an important role in impression formation. A more reliable source of information in impression formation is moral behavior, which forms the primary basis for the comprehensive evaluation of others. Previous studies have found that one can easily form an association when faces and moral behaviors are presented together, which in turn affects facial attractiveness evaluation.

Chlorophyll (Chl) is a key pigment for wheat (Triticum aestivum L.) photosynthesis, consequently impacts grain yield. A wheat mutant named as delayed virescence 4 (dv4) was obtained from cultivar Guomai 301 (wild type, WT) treated with ethyl methane sulfonate (EMS).

Article Synopsis
  • The radicle is the first root to grow during seed germination, playing a crucial role in the establishment and survival of wheat seedlings, yet its growth mechanisms are under-researched.
  • A study analyzed 196 wheat accession samples over 3 years to measure radicle length variations in hydroponic environments, identifying key genes and proteins related to long and short root traits through RNA-seq and iTRAQ methods.
  • Genome-wide association studies revealed important chromosomal regions impacting radicle length, and specific gene expression changes were linked to processes like photosynthesis and cell wall development, with one notable gene (CRK6) linked to improved root growth when silenced.

Interest has been growing in the role of subjective aesthetics in the field of food. This study explored the mechanisms by which the aesthetic appeal of plate patterns influences consumers' perceptions of food. Three experiments were conducted to compare whether different levels of beauty and types of plate pattern aesthetics (classical versus expressive) affected the perceptions of tastiness and healthiness of the food offered.

How does aging affect facial attractiveness? We tested the hypothesis that people find older faces less attractive than younger faces, and furthermore, that these aging effects are modulated by the age and sex of the perceiver and by the specific kind of attractiveness judgment being made. Using empirical and computational network science methods, we confirmed that with increasing age, faces are perceived as less attractive. This effect was less pronounced in judgments made by older than younger and middle-aged perceivers, and more pronounced by men (especially for female faces) than women.

Leaf is the major photosynthesis organ and the key source of wheat (Triticum aestivum L.) grain. Spotted leaf (spl) mutant is a kind of leaf lesion mimic mutants (LMMs) in plants, which is an ideal material for studying the mechanisms of leaf development.

Article Synopsis
  • Plant roots play a crucial role in acquiring water and nutrients, adapting to environments, and influencing wheat yield, prompting a study of 196 wheat accessions across various growing conditions including indoor and outdoor hydroponics, and pot culture.
  • The study found that root traits exhibited the most variation in pot culture, with faster root growth observed in hydroponic settings, and correlations were established between certain root traits and grain yield metrics.
  • A genome-wide association study identified stable regions on several chromosomes linked to root traits, highlighting genes involved in root development and their connection to yield-related traits like thousand-kernel weight.

Background: Fusarium crown rot is major disease in wheat. However, the wheat defense mechanisms against this disease remain poorly understood.

Results: Using tandem mass tag (TMT) quantitative proteomics, we evaluated a disease-susceptible (UC1110) and a disease-tolerant (PI610750) wheat cultivar inoculated with Fusarium pseudograminearum WZ-8A.

To set a systematic study of the Sorghum () gene family, a genome-wide analysis of the family genes was performed by bioinformatics-based methods. In total, 18 genes were identified in Sorghum, which were distributed unevenly on chromosomes, and two genes were involved in a tandem duplication event. All genes had similar exon/intron structure and motifs, indicating their high evolutionary conservation.

Article Synopsis
  • The study investigates the root systems of wheat, focusing on both seminal and nodal roots, with a greater emphasis on the latter due to its early disappearance in controlled environments.
  • It examines 196 wheat accessions from the Huanghuai Wheat Region across various growth environments, revealing that pot culture shows greater root trait variation compared to hydroponic setups, and that root traits correlate negatively with key yield indicators.
  • The research identifies 35 quantitative trait loci (QTLs) linked to root traits using a 660K SNP array, highlighting significant QTLs tied to nodal root numbers and noting the limited presence of favorable alleles in natural populations, indicating potential for genetic improvement.

Field experiment was conducted to examine the effects of combined application of N and Zn fertilizers on translocation, distribution, and accumulation of Zn in different organs in wheat plants. The results showed that Zn concentration and Zn accumulation in each organ were significantly different under different treatments. Compared with N (120 kg·hm), the grain Zn concentration of N (240 kg·hm) and N (180 kg·hm) increased 22.

Temporal concepts could be represented horizontally(X-axis) or vertically (Y-axis). However, whether the spatial representation of time exists in the whole plane remains unclear. In this study, we investigated whether processing temporal concepts would automatically activate spatial representations in a whole plane without any guidance or cue.

Powdery mildew of wheat is one of the major foliar diseases, causing significant yield loss and flour quality change. In this study, grain protein and starch response to powdery mildew infection were investigated. Total protein, glutenin and gliadin exhibited a greater increase in grains from infected wheat, while the content of total starch and amylopectin was decreased.

Recent studies suggest that when inhibitory control is lacking, people are more inclined to indulge in high-calorie food, but inhibitory control can be trained. In this study, a daily-life training game was used to train children and investigate whether strengthening or weakening inhibitory control influences food intake in opposite directions. The baseline of response inhibition was measured by the go/no-go task, and the baseline of food intake was measured by a bogus food taste task.
