Comparative Analysis of Ca/Cation Antiporter Gene Family in and Enhanced Calcium Stress Tolerance via Heterologous Expression of RrCAX1a in Tobacco.

, a calciphilic species native to the mountainous regions of Southwest China, is renowned for its high vitamin C and bioactive components, making it valuable for culinary and medicinal uses. This species exhibits remarkable tolerance to the high-calcium conditions typical of karst terrains. However, the underlying mechanisms of this calcium resilience remain unclear.

Research progress on the effects of elevated atmospheric CO concentration on CH emission and related microbial processes in paddy fields.

Paddy fields are recognized as significant sources of methane (CH) emissions, playing a pivotal role in global climate change. Elevated atmospheric carbon dioxide (CO) concentrations (e[CO]) exert a profound influence on the carbon cycling of paddy fields. Understanding the effects of e[CO] on CH emissions, as well as the underlying microbial processes, is crucial for enhancing carbon sequestration and reducing emissions in paddy fields.

The quantification of root exudation by an method based on root morphology over three incubation periods.

Investigating the quantity and spatiotemporal dynamics of metabolite release from plant roots is essential if we are to understand the ecological significance of root exudates in the rhizosphere; however, this is difficult to quantify. In the present study, we quantified root exudation rates during three incubation periods (0-24, 24-48, and 48-72 h) and fine roots within four diameter ranges (<0.8, 0.

The effect of exogenous gibberellin and its synthesis inhibitor treatments for morphological and physiological characteristics of Tartary buckwheat.

Gibberellin (GA) is an important plant hormone involved in many physiological and developmental processes in plants. However, the physiological mechanism of GA on the regulation yield and grain shell thickness of Tartary buckwheat is still unclear. In this study, the thick-shelled cultivar "Jinqiao 2" and thin-shelled cultivar "Miku 18" were used to study the effects of different concentrations (0, 50, and 100 mg L) of exogenous GA and chlorocholine chloride (CCC, GA synthesis inhibitor) on the cellulose content, amylase, and sucrose synthase (SS) activity in grain shell and the yield of Tartary buckwheat.

Potassium fertilizer promotes the thin-shelled Tartary buckwheat yield by delaying senescence and promoting grain filling.

The application rate of potassium fertilizer is closely related to the yield of crops. Thin-shelled Tartary buckwheat is a new variety of Tartary buckwheat with the advantages of thin shell and easy shelling. However, little is known about application rate of potassium fertilizer on the yield formation of thin-shelled Tartary buckwheat.

Increasing planting density can improve the yield of Tartary buckwheat.

Planting densities and nitrogen fertilizer application rates determine the yield of crops. Tartary buckwheat is a pseudocereal crop with great health care and development values. However, little is known about application of nitrogen fertilizer and planting density on the physiological characteristics of Tartary buckwheat.

Eco-Stoichiometric Characteristics of Rhizosphere and Bulk Soils of L. along Vertical Zone Spectrum of Fanjing Mountain.

To explore the correlations between nutrients and stoichiometric characteristics in the rhizosphere and bulk soils of understory L. in forest ecosystems at different altitudes and to clarify the rhizosphere effect of understory vegetation in forest ecosystems and its response strategy to altitude, providing a theoretical basis for better forest ecological environment protection and high-quality development in Fanjing Mountain. Understory L.

A Case Study Demonstrates That the Litter of the Rare Species Composed of Different Tissues Can Affect the Chemical Properties and Microbial Community Diversity in Topsoil.

The decomposition of litter plays an important role in the return of forest soil nutrients, as well as the growth and productivity of plants. With this study, we aimed to determine the impact of litter mulching on different tissues of , a rare Chinese endemic species. In particular, seeds and pericarp are easily overlooked components of litter.

Effect of storage time on biochemical characteristics and antioxidant activity of hawk tea () processed by boiling water fixation.

This study investigated the effect of storage time on biochemical characteristics of hawk tea () and explored the correlation between the content of flavonoids and polyphenols and antioxidant activity. The antioxidant activity and the content of inclusions, amino acid, and mineral elements in hawk tea processed by boiling water fixation and packed in airtight polypropylene bags and stored in 0°C refrigerator under different storage time (one year, three years, and six years) were analyzed. Results indicated that the biochemical characteristics of hawk tea changed less within 12 months.
