Article Synopsis
  • Drought stress is increasingly threatening plant growth and agricultural yields worldwide as climate conditions worsen and water resources diminish.
  • Research has shown that DNA methylation plays a significant role in how plants respond to drought by regulating gene expression and development, though the exact mechanisms are not fully understood.
  • This review synthesizes the latest findings on DNA methylation's impact on drought stress, highlighting detection methods, alteration mechanisms, and a call for more specific identification of genes and pathways involved in drought resistance.

Article Synopsis
  • Soilless cultivation for potatoes uses coconut peat and vermiculite as substrates, impacting the microecological environment essential for growth and breeding due to their unique microbial communities and physical properties.! -
  • The study analyzed various samples, including pure and mixed substrates, and utilized advanced sequencing techniques to explore the microbial community's relationship with environmental factors, revealing that vermiculite generally has lower diversity and more pathogens compared to coconut peat, which supports a richer microbiome.! -
  • Key environmental factors like nitrogen and organic carbon significantly affect microbial succession, indicating that nutrient management is crucial for maintaining microbial health and stability in the growing substrates, especially when using vermiculite for potato cultivation.!

Recently, learning-based multi-exposure fusion (MEF) methods have made significant improvements. However, these methods mainly focus on static scenes and are prone to generate ghosting artifacts when tackling a more common scenario, i.e.

To explore the application effect of the Knowledge, Attitude, and Practice (KAP) model combined with motivational interviewing for health education in the chronic disease management of female patients with systemic lupus erythematosus (SLE). In this study, 84 women with SLE who were admitted to a tertiary hospital in Tianjin from July 2021 to April 2022 were enrolled in this study and divided into observation (n = 42) and control groups (n = 42). The control group received routine health education and treatment for chronic diseases.

Turcz, a perennial herb of the Asteraceae family, is one of the horticultural and medicinal plants used for curing various diseases and is widely distributed in China and other Asian countries. It possesses antibacterial, antimetastatic, antiangiogenic, and antioxidant properties along with anticancer potential. However, the intrageneric classification and phylogenetic relationships within have long been controversial due to the lack of high-resolution molecular markers, and the complete chloroplast (cp) genome sequencing has not been reported with new evolutionary insights.

The taxonomic terms "" and "" had been used to describe two sections within the genus belonging to the Lamiaceae family. Recently, phylogenetic analyses using molecular markers showed that and formed two monophyletic clades, and thus they are generally accepted as separate genera. In this study, we assembled the complete chloroplast genome of , which is the first reported chloroplast genome belonging to genus, as well as the complete chloroplast genome of belonging to genus.

Potato ( L) is the third important crop for providing calories to a large human population, and is considered sensitive to moderately sensitive to drought stress conditions. The development of drought-tolerant, elite varieties of potato is a challenging task, which can be achieved through molecular breeding. Recently, the () gene has been identified in rice, which influences plant root system and regulates grain yield under drought stress conditions.

A new resonant-type inertial impact piezoelectric motor based on a cam locking mechanism was designed, assembled, and tested. The motor is composed of a stator, a rotor, and other auxiliary components. The cam clamping foot of the stator in contact with the inner surface of the rotor forms a cam locking mechanism, which can make the resonant vibration of the stator effective in a half cycle.

Crop plants often have challenges of biotic and abiotic stresses, and they adapt sophisticated ways to acclimate and cope with these through the expression of specific genes. Changes in chromatin, histone, and DNA mostly serve the purpose of combating challenges and ensuring the survival of plants in stressful environments. Epigenetic changes, due to environmental stress, enable plants to remember a past stress event in order to deal with such challenges in the future.

In a typical digital fringe projection (DFP) system, the shadows in the fringe images cause errors in the phase map. We propose a novel discriminative repair approach to remove the shadow-induced error in the phase map. The proposed approach first classifies the shadow area in the phase map obtained by the DFP into two categories: valid shadow area and invalid shadow area.

Pixel-by-pixel phase unwrapping (PPU) has been employed to rapidly achieve three-dimensional (3-D) shape measurement without additional projection patterns. However, the maximum measurement depth range that traditional PPU can handle is within 2π in phase domain; thus PPU fails to measure the dynamic object surface when the object moves in a large depth range. In this paper, we propose a novel adaptive pixel-by-pixel phase unwrapping (APPU), which extends PPU to an unlimited depth range.

Article Synopsis
  • The study focuses on identifying and characterizing mutations in BRI1, a key receptor for brassinosteroids in the plant Arabidopsis, to better understand its cellular functions.
  • Over 20 mutant alleles have already been identified, and the research presents 83 new point mutations, highlighting variations in phenotypic expressions ranging from subtle to severe.
  • Biochemical analyses reveal that certain mutations affect BRI1's activity, including one that shows reduced auto-phosphorylation and others that disrupt interactions with brassinolide and co-receptors, providing new insights into brassinosteroid signaling mechanisms.
