Foliar Spray Treatment for Exogenous Application of Hormones in Maize.

Exogenous application of hormones in plants is a valuable technique for studying and manipulating plant growth, development, and responses to environmental stimuli. The foliar spray method is one of the most common approaches for the exogenous application of hormones in plants due to its ease of use on aerial organs (such as leaves and inflorescences) and the rapid absorption of the treated tissue, facilitating subsequent analyses. Here, we provide a protocol to implement this method in maize.

Apical Whorl Treatment for Exogenous Application of Hormones in Maize.

Plant hormones play an essential role in both development and stress responses. These organic natural compounds have critical functions in plant-related processes, including but not limited to seed development, anther formation, root elongation, and responses to abiotic and biotic stress. One way to study the impact of hormones on these processes is by external application, followed by evaluation of parameters of interest.

Exogenous Hormone Treatments in Maize.

Plant hormones have key functions in plant morphology, physiology, and stress responses. Studies on the biology of hormones and their effect on plant physiology and metabolism are greatly facilitated by the exogenous application of these compounds. In general, methods for exogenous hormone application are easy and fast, and provide useful information about their effects in planta.

CRISPR/Cas9-mediated multiplex gene editing of gamma and omega gliadins: paving the way for gliadin-free wheat.

Wheat is a staple cereal in the human diet. Despite its significance, an increasing percentage of the population suffers adverse reactions to wheat, which are triggered by wheat gluten, particularly the gliadin fractions. In this study, we employed CRISPR/Cas [clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated protein] multiplexing to introduce targeted mutations into γ- and ω-gliadin genes of wheat, to produce lines deficient in one or both immunogenic gliadin fractions simultaneously.

Molecular Insights into Plant-Microbe Interactions: A Comprehensive Review of Key Mechanisms.

In most ecosystems, plants establish complex symbiotic relationships with organisms, such as bacteria and fungi, which significantly influence their health by promoting or inhibiting growth. These relationships involve biochemical exchanges at the cellular level that affect plant physiology and have evolutionary implications, such as species diversification, horizontal gene transfer, symbiosis and mutualism, environmental adaptation, and positive impacts on community structure and biodiversity. For these reasons, contemporary research, moving beyond observational studies, seeks to elucidate the molecular basis of these interactions; however, gaps in knowledge remain.

Identification of RNAi hypoallergic bread wheat lines for wheat-dependent exercise-induced anaphylaxis patients.

The optimal treatment approach for these fractures remains uncertain. This review aims to compare the use of cannulated screws versus plate with screw fixation in terms of their impact on the development of postoperative ankle osteoarthritis and functional outcomes in patients with PM fractures.

Initial evaluation and external validation of 68Ga-PSMA-11 PET/CT in tubarial gland characterization.
