A research team used synchrotron-based X-ray microcomputed tomography (SR-μCT) to non-invasively obtain high-quality 3D images of fresh soybean root nodules, quantifying the volumes of the central infected zone (CIZ) and vascular bundles (VBs).
In a significant advancement for agricultural biotechnology, researchers have identified a genetic mechanism that enhances the cold tolerance of tomatoes. This breakthrough is pivotal for cultivating crops in cooler climates, ensuring stable yields and bolstering global food security.
Tomato fruit ripening, a process initiated by key gene demethylation, is significantly influenced by postharvest handling practices. These practices, while extending shelf life, can alter ripening dynamics and affect fruit quality.
Summer heat can take a toll on lawns and plants, especially when rain isn’t in the forecast. Virginia Tech turfgrass experts Mike Goatley and Dan Sandor share tips for keeping a healthy lawn during a drought. What time of day should you water your lawn during extreme sun and heat? “Irrigate early in the morning whenever possible,” Goatley said.
In a recent discovery poised to enhance agricultural resilience, scientists have demystified the elaborate cold resistance mechanisms of the white water lily—a plant that flourishes in the frigid climes of Xinjiang's lofty terrains. A thorough investigation into the lily's morphological adaptations, strategic resource distribution, and metabolic reactions has unveiled an intricate regulatory framework encompassing phytohormone signaling, amino acid metabolism, and circadian rhythms. This revelation provides invaluable insights for bolstering the cold resistance of crops.
A pioneering study has shed light on the biosynthesis of glucomannan in Bletilla striata, a plant known as BaiJi with profound medicinal properties. The research meticulously maps the conversion process from sucrose to bioactive glucomannan polysaccharides, pinpointing key genes that orchestrate this transformation.
A pivotal study illuminates the genetic dynamics in tissue-specific interactions between apple trees and Valsa mali, a fungus causing severe disease. By examining the adaptive regulation of miRNAs and milRNAs, researchers uncover distinct expression profiles crucial for understanding and potentially manipulating the plant's defense mechanisms against pathogens.
A research team used hyperspectral data and deep convolution generative adversarial networks (DCGANs) to improve the accuracy of rice grain protein content (GPC) estimation. By generating simulated data, they enhanced the model's performance, achieving an R² of 0.58 and RRMSE of 6.70%.
A research team developed the Point-Line Net, a deep learning method based on the Mask R-CNN framework, to automatically recognize maize field images and determine the number and growth trajectory of leaves and stalks.
A pivotal study has shed light on a critical genetic mechanism that boosts plants' ability to withstand drought. The research uncovers the role of the transcription factor PbERF3, native to wild pears, which works in concert with the protein PbHsfC1a to regulate genes key to drought tolerance.
Urban agriculture has the potential to improve food security through local, efficient, and sustainable food production. Examples of urban food systems include hydroponics, where plants grow in a nutrient solution without soil, and aquaponics, which combines hydroponics with raising fish in tanks.
To produce biofuels from nonedible plants, researchers can use cellulase to break down plant cellulose into glucose, which can be fermented to generate bioethanol. Researchers have now used a specialized optical microscope to visualize single cellulase enzymes interacting with different forms of cellulose. This allowed them to investigate enzyme function in the presence of the product of the reaction and other components of plant biomass.
