Integrated analysis of phenome, genome, and transcriptome of hybrid rice uncovered multiple heterosis-related loci for yield increase

Because of its practical importance and scientific significance, heterosis (hybrid vigor) is an interesting topic for both breeders and biologists

Dynamic regulation of auxin oxidase and conjugating enzymes AtDAO1 and GH3 modulates auxin homeostasis

Auxin is a key hormone regulating plant growth and development. We combine experiments and mathematical modeling to reveal how auxin levels are maintained via feedback regulation of genes encoding key metabolic enzymes. We describe how regulation of auxin oxidation via transcriptional control of Arabidopsis thaliana gene DIOXYGENASE FOR AUXIN OXIDATION 1 (AtDAO1) expression is important at low to normal auxin concentrations

Brassinosteroids participate in the control of basal and acquired freezing tolerance of plants

In this work we reveal that the brassinosteroids, a class of steroid hormones that is known for its role in growth control, also confers freezing tolerance in plants and describe regulatory circuits that contribute to this activity. Implications for the breeding of cold-resistant plants are discussed

Maize Genetics Helps Scientists Study Crop Adaptation to Climate Change

Scientists from the University of California Davis are leading a new project to study the genetic adaptation of maize to different environmental conditions. The team is looking at the genetic basis of maize adaptation to high-elevation environments, to find out how wild and domesticated maize populations adapt to new climates.

New Wheat Varieties with Dwarf Genes Show Promise

The Department of Agriculture and Food of Western Australia is field testing new wheat lines developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Senior research officer Dr. Bob French said the new lines contained alternative dwarfing genes that had a longer coleoptile length, the pointed protective sheath that encases the emerging shoot as it grows from the seed to the soil surface.

Comparative transcriptomics of rice plants under cold, iron, and salt stresses

Abiotic stresses such as salinity, iron toxicity, and low temperatures are the main limiting factors of rice (Oryza sativa L.) yield. The elucidation of the genes involved in responses to these stresses is extremely important to understand the mechanisms that confer tolerance, as well as for the development of cultivars adapted to these conditions. In this study, the RNA-seq technique was used to compare the transcrip-tional profile of rice leaves (cv. BRS Querência) in stage V3

Repeated replacement of an intrabacterial symbiont in the tripartite nested mealybug symbiosis

Mealybugs are plant sap-sucking insects with a nested symbiotic arrangement, where one bacterium lives inside another bacterium, which together live inside insect cells. These two bacteria, along with genes transferred from other bacteria to the insect genome, allow the insect to survive on its nutrient-poor diet.

Investigating the Control of Chlorophyll Degradation by Genomic Correlation Mining.

Chlorophyll degradation is an intricate process that is critical in a variety of plant tissues at different times during the plant life cycle. Many of the photoactive chlorophyll degradation intermediates are exceptionally cytotoxic necessitating that the pathway be carefully coordinated and regulated.

RPT2/NCH1 subfamily of NPH3-like proteins is essential for the chloroplast accumulation response in land plants

The photoreceptor phototropin mediates various blue light-induced responses, including phototropism, chloroplast movement, stomatal opening, and leaf flattening.

Histone deacetylase HDA6 enhances brassinosteroid signaling by inhibiting the BIN2 kinase

The brassinosteroid (BR) signaling pathway has important functions in plant development, but the mechanisms that control its key regulator BR-INSENSITIVE 2 (BIN2) remain poorly understood.

FERONIA interacts with ABI2-type phosphatases to facilitate signaling cross-talk between abscisic acid and RALF peptide in Arabidopsis

Receptor-like kinase FERONIA (FER) not only serves as a receptor for growth-regulating rapid alkalinization factor (RALF) peptide but also acts as an important node in a variety of other signaling pathways, including plant responses to hormones, pathogens, and abiotic stresses.

Vietnam, Thailand in Phillipines rice deal

Thailand and Viet Nam have won deals to supply a total of 250,000 tonnes of rice to the Philippines after the two countries reduced their selling prices to suit Manila’s budget.

Inter-genomic DNA Exchanges and Homeologous Gene Silencing Shaped the Nascent Allopolyploid Coffee Genome (Coffea arabica L.)

Allopolyploidization is a biological process that has played a major role in plant speciation and evolution. Genomic changes are common consequences of polyploidization, but their dynamics over time are still poorly understood.

Event DAS-444Ø6-6 soybean grown in Brazil is compositionally equivalent to non-transgenic soybean

Soybean event DAS-444Ø6-6 is tolerant to the herbicides 2,4-D, glyphosate, and glufosinate. An investigation of potential unintended adverse compositional changes in a genetically modified crop is required to meet government regulatory requirements in various geographies.
