An Integrative Analysis of the Transcriptome and Proteome of Rice Grain Chalkiness Formation Under High Temperature.

Exposure to high temperatures can impair the grain-filling process in rice ( L.), potentially leading to the formation of chalky endosperm, but the molecular regulation mechanism remains largely elusive. Here, we reported that high-temperature (HT) stress (day/night, 35 °C/30 °C) reduces both the grain-filling rate and grain weight of Ningjing 1 variety compared to normal temperatures (NT, day/night, 28 °C/23 °C).

Impacts of elevated CO and partial defoliation on mineral element composition in rice.

Introduction: This study explores how elevated CO concentration may alter the source-sink dynamics in rice by providing additional carbon for photosynthesis, thereby affecting nutrient absorption and distribution.

Methods: A free-air CO enrichment experiment was conducted on a japonica cultivar Wuyunjing 27 in 2017 and 2018 growing seasons. The plants were exposed to ambient and elevated CO level (increased by 200 μmol·mol-1) and two source-sink manipulation treatments (control with no leaf cutting and cutting off the top three leaves at heading).

Genome-wide identification and analysis of the cotton ALDH gene family.

Background: Aldehyde dehydrogenases (ALDHs) are a family of enzymes that catalyze the oxidation of aldehyde molecules into the corresponding carboxylic acid, regulate the balance of aldehydes and protect plants from the poisoning caused by excessive accumulation of aldehydes; however, this gene family has rarely been studied in cotton.

Results: In the present study, genome-wide identification was performed, and a total of 114 ALDH family members were found in three cotton species, Gossypium hirsutum, Gossypium arboreum and Gossypium raimondii. The ALDH genes were divided into six subgroups by evolutionary analysis.

A comprehensive overview of omics-based approaches to enhance biotic and abiotic stress tolerance in sweet potato.

Biotic and abiotic stresses negatively affect the yield and overall plant developmental process, thus causing substantial losses in global sweet potato production. To cope with stresses, sweet potato has evolved numerous strategies to tackle ever-changing surroundings and biological and environmental conditions. The invention of modern sequencing technology and the latest data processing and analysis instruments has paved the way to integrate biological information from different approaches and helps to understand plant system biology more precisely.

Salinity inhibits seed germination and embryo growth by reducing starch mobilization efficiency in barley.

Barley is one of the world's earliest domesticated crops, which is widely used for beer production, animal feeding, and health care. Barley seed germination, particularly in increasingly saline soils, is key to ensure the safety of crop production. However, the mechanism of salt-affected seed germination in barley remains elusive.

Genome-wide identification of long intergenic non-coding RNAs of responsive to powdery mildew stress in wheat ().

Wheat powdery mildew caused by f. sp. is one of the most serious foliar diseases of wheat, causing grain yield and quality degradation by affecting plant photosynthesis.

Genome-wide analysis of the LAZ1 gene family in Gossypium hirsutum.

Background: As the world's leading fiber crop and a major oil-producing crop, cotton fiber yield and fiber quality are affected by environmental stresses, especially heat, drought and salinity. The LAZ1 (Lazarus 1) family genes are responsive to abscisic acid, drought, and salt treatments. Currently, mining and functional analyses of LAZ1 family genes in cotton have not been reported.

Microbial ecological clusters structured by environments drive maize residue decomposition at the continental scale.

Environmental factors (e.g., climate and edaphic factors) indirectly regulate residue decomposition via microbial communities.

NLRs derepress MED10b- and MED7-mediated repression of jasmonate-dependent transcription to activate immunity.

Plant intracellular nucleotide-binding domain, leucine-rich repeat-containing receptors (NLRs) activate a robust immune response upon detection of pathogen effectors. How NLRs induce downstream immune defense genes remains poorly understood. The Mediator complex plays a central role in transducing signals from gene-specific transcription factors to the transcription machinery for gene transcription/activation.

Pigment Biosynthesis and Molecular Genetics of Fruit Color in Pepper.

Pepper, as a vegetable crop with a wide cultivation area worldwide, besides being a significant condiment and food, also has a momentous use for chemistry, medicine, and other industries. Pepper fruits are rich in various pigments, such as chlorophyll, carotenoids, anthocyanins, and capsanthin, which have important healthcare and economic value. Since various pigments are continuously metabolized during the development of pepper fruits, peppers exhibit an abundant fruit-colored phenotype in both the mature and immature periods.

Genome-wide characterization of ascorbate peroxidase gene family in pepper ( L.) in response to multiple abiotic stresses.

Pepper is widely grown all over the world, so it faces many abiotic stresses, such as drought, high temperature, low temperature, salt damage, and so on. Stresses causing the accumulation of reactive oxidative species (ROS) in plants are removed by antioxidant defense systems, and ascorbate peroxidase (APX) is an important antioxidant enzyme. Therefore, the present study performed genome-wide identification of the gene family in pepper.

Bacillus velezensis BER1 enriched Flavobacterium daejeonense-like bacterium in the rhizosphere of tomato against bacterial wilt.

Beneficial microorganisms can protect crop from phytopathogens, and modify rhizosphere microbiome. However, it is not well-understood whether or how do rhizosphere microorganisms which respond to bioagents contribute to disease suppression. Bacillus velezensis BER1 and tomato bacterial wilt caused by Ralstonia solanacearum were selected as models to disentangle the interactions and mechanisms in the rhizosphere.

OsTKPR2 is part of a sporopollenin-producing metabolon required for exine formation in rice.

The sporopollenin polymer is a major component of the pollen exine. Fatty acid derivatives synthesized in the tapetum are among the precursors of sporopollenin. Progress has been made to understand sporopollenin metabolism in rice; however, the underlying molecular mechanisms remain elusive.

Lung inflammation induced by Mycoplasma hyorhinis infection accounts for significant economic losses in the swine industry. Increasing evidence suggests that there is cross talk between the lungs and the gut, but little is known about the effect of the lung inflammation caused by infection on gut microbiota and intestinal barrier function. Here, we investigated changes in the fecal microbiotas of pigs with infection and the microbial regulatory role of such infection in intestinal barrier function.

Rhizobia-Legume Symbiosis Increases Aluminum Resistance in Alfalfa.

Alfalfa is the most important forage legume with symbiotic nitrogen-fixing nodule in roots, but it is sensitive to aluminum (Al), which limits its plantation in acidic soils. One rhizobia clone of with Al tolerance (AT1) was isolated from the nodule in AlCl-treated alfalfa roots. AT1 showed a higher growth rate than the standard rhizobia strain Sm1021 under Al-stressed conditions.
