Stem water potential estimation from images using a field noise-robust deep regression-based approach in peach trees.

Field-grown peach trees are large and have a complex branch structure; therefore, detection of water deficit stress from images is challenging. We obtained large datasets of images of field-grown peach trees with continuous values of stem water potential (Ψstem) through partial secession treatment of the base of branches to change the water status of the branches. The total number of images as frames extracted from videos of branches was 23,181, 6743, and 10,752, in the training, validation, and test datasets, respectively.

HortNet417v1-A Deep-Learning Architecture for the Automatic Detection of Pot-Cultivated Peach Plant Water Stress.

The biggest challenge in the classification of plant water stress conditions is the similar appearance of different stress conditions. We introduce HortNet417v1 with 417 layers for rapid recognition, classification, and visualization of plant stress conditions, such as no stress, low stress, middle stress, high stress, and very high stress, in real time with higher accuracy and a lower computing condition. We evaluated the classification performance by training more than 50,632 augmented images and found that HortNet417v1 has 90.

Inhibitory Effects of Juices Prepared from Individual Vegetables on CYP3A4 Activity in Recombinant CYP3A4 and LS180 Cells.

Human intestinal absorption and drug metabolism vary to a large extent among individuals. For example, CYP3A4 activity has large individual variation that cannot be attributed to only genetic differences. Various flavonoids in vegetables, such as kaempferol and quercetin, possess inhibitory effects, and some vegetable and fruit juices have also been found to inhibit CYP3A4 activity.

Derivation of consensus sequence for protein binding site in Yarrowia lipolytica centromere.

The transmission of replicative plasmids in the yeast Yarrowia lipolytica is mediated solely by a part of its centromere DNA, in which an essential protein binding site has been analyzed recently. Here, we extended the analysis to other minimized centromeric regions, revealing a consensus sequence of a 17- to 21-bp imperfect palindrome.

Dissection of centromeric DNA from yeast Yarrowia lipolytica and identification of protein-binding site required for plasmid transmission.

In a dimorphic yeast, Yarrowia lipolytica, replicative plasmids can be established only in the coexistence of the replication origin (ORI) and centromere (CEN) from its own chromosomal DNA. Although six CEN sequences so far isolated from this yeast exhibit no similarity with conventional CEN DNA elements from other budding yeasts, they are confined within short regions (approximately 0.2 kb) and contain various conserved sequence blocks.
