The role of sugar transporter BrSWEET11 in promoting plant early flowering and preliminary exploration of its molecular mechanism.

BrSWEET11 accelerated Arabidopsis thaliana flowering, while silencing Brsweet11 in Brassica rapa delayed flowering relative to controls. BrSWEET11 is involved in sucrose transport after being induced by long-day conditions. SWEETs (Sugars Will Eventually Be Exported Transporters) are sugar outflow transporters that may participate in the regulation of plant flowering.

Contrasting effects of organic materials versus their derived biochars on maize growth, soil properties and bacterial community in two type soils.

The objective of this study was to assess the benefit of applying biochar instead of its feedstock in enhancing soil quality. To accomplish this, we investigated the short-term effects of two organic materials and their derived biochars on maize growth, soil properties, and microbial community in fluvo-aquic and red soil with a pot experiment. Five treatments were applied to each soil, namely, the addition of straw, manure, straw-derived biochar, manure-derived biochar, and the control with no addition of any organic materials and biochar.

Genome-wide identification of (Na/H antiporter) gene family in and functional analysis of under salt stress.

Soil salinization, which is the accumulation of salt in soil, can have a negative impact on crop growth and development by creating an osmotic stress that can reduce water uptake and cause ion toxicity. The NHX gene family plays an important role in plant response to salt stress by encoding for Na/H antiporters that help regulate the transport of sodium ions across cellular membranes. In this study, we identified 26 genes in three cultivars of L.

Transcriptome Analysis Revealed the Molecular Response Mechanism of Non-heading Chinese Cabbage to Iron Deficiency Stress.

Iron is a trace metal that is found in animals, plants, and the human body. Human iron absorption is hampered by plant iron shortage, which leads to anemia. Leafy vegetables are one of the most direct and efficient sources of iron for humans.

Identification of genes related to tipburn resistance in Chinese cabbage and preliminary exploration of its molecular mechanism.

Background: Tipburn, also known as leaf tip necrosis, is a severe issue in Chinese cabbage production. One known cause is that plants are unable to provide adequate Ca to rapidly expanding leaves. Bacterial infection is also a contributing factor.

Genome-wide identification of alcohol dehydrogenase (ADH) gene family under waterlogging stress in wheat ().

Background: Alcohol dehydrogenase () plays an important role in plant survival under anaerobic conditions. Although some research about in many plants have been carried out, the bioinformatics analysis of the gene family from and their response to abiotic stress is unclear.

Methods: A total of 22 genes were identified from the wheat genome, and these genes could be divided into two subfamilies (subfamily I and subfamily II).

Genome-Wide Characterization and Expression Analysis of Gene Family Under Salt Stress in and .

Linn. vegetables have a long history of cultivation and have been cultivated all over the world. With the increasing area of saline-alkali soil, Linn.

Transcriptome Analysis of Seedling Root Responses to Short-Term Potassium Deficiency.

Potassium (K) plays a crucial role in multiple physiological and developmental processes in plants. Its deficiency is a common abiotic stress that inhibits plant growth and reduces crop productivity. A better understanding of the mechanisms involved in plant responses to low K could help to improve the efficiency of K use in plants.

Genome-wide characterization and expression analysis of the heat shock transcription factor family in pumpkin (Cucurbita moschata).

Background: Crop quality and yield are affected by abiotic and biotic stresses, and heat shock transcription factors (Hsfs) are considered to play important roles in regulating plant tolerance under various stresses. To investigate the response of Cucurbita moschata to abiotic stress, we analyzed the genome of C. moschata.

Genome-Wide Investigation and Expression Analysis of K-Transport-Related Gene Families in Chinese Cabbage (Brassica rapa ssp. pekinensis).

Potassium (K) transport and channel systems play vital roles in plant growth, development and responses to various stresses. In this study, 44 putative K-transport-related genes (18K uptake permease (KUP)/high-affinity K (HAK)/K transporter (KT) family genes and 26 channel genes, including 18 Shaker family genes and 8K channel outward (KCO) family genes) were identified in the genome of Chinese cabbage (Brassica rapa ssp. pekinensis).

Transcriptomic and anatomic profiling reveal the germination process of different wheat varieties in response to waterlogging stress.

Background: Waterlogging is one of the most serious abiotic stresses affecting wheat-growing regions in China. Considerable differences in waterlogging tolerance have been found among different wheat varieties, and the mechanisms governing the waterlogging tolerance of wheat seeds during germination have not been elucidated.

Results: The results showed no significant difference between the germination rate of 'Bainong 207' (BN207) (after 72 h of waterlogging treatment) and that of the control seeds.

The change in microstructure of petioles and peduncles and transporter gene expression by potassium influences the distribution of nutrients and sugars in pear leaves and fruit.

Potassium (K) is one of the most important mineral nutrients required for fruit growth and development and is known as a 'quality element'. To investigate the role of K in more detail, we performed experiments in which seven-year-old pot-grown 'Huangguan' pear trees were treated with three levels of K (0, 0.4, or 0.

Transcriptome Analysis of Differentially Expressed Genes Induced by Low and High Potassium Levels Provides Insight into Fruit Sugar Metabolism of Pear.

Potassium (K) deficiency is a common abiotic stress that can inhibit the growth of fruit and thus reduce crop yields. Little research has been conducted on pear transcriptional changes under low and high K conditions. Here, we performed an experiment with 7-year-old pot-grown "Huangguan" pear trees treated with low, Control or high K levels (0, 0.

Non-Destructive Evaluation of the Leaf Nitrogen Concentration by In-Field Visible/Near-Infrared Spectroscopy in Pear Orchards.

Non-destructive and timely determination of leaf nitrogen (N) concentration is urgently needed for N management in pear orchards. A two-year field experiment was conducted in a commercial pear orchard with five N application rates: 0 (N0), 165 (N1), 330 (N2), 660 (N3), and 990 (N4) kg·N·ha. The mid-portion leaves on the year's shoot were selected for the spectral measurement first and then N concentration determination in the laboratory at 50 and 80 days after full bloom (DAB).

Effective energy coupling and preservation in a surface plasmon-light emitter coupling system on a metal nanostructure.

The simulation results of the coupling of a radiation dipole with a surface plasmon (SP), which is induced on a metal/dielectric interface of a single groove (SG) plus a grating structure, are demonstrated. With the SG structure, the dipole can effectively couple energy into an SP feature, which has a mixed nature of localized surface plasmon (LSP) and surface plasmon polariton (SPP). The SPP energy is confined by a grating structure with a well designed grating period and position.
