Draft genome sequences have been determined for the soybean pathogen Phytophthora sojae and sudden oak death ramorum. Oömycetes such as these species share kingdom Stramenopila with photosynthetic algae diatoms, presence of many genes probable phototroph origin supports a ancestry stramenopiles. Comparison two species' genomes reveals rapid expansion diversification protein families associated plant infection hydrolases, ABC transporters, toxins, proteinase inhibitors, and, in particular,...
Abstract Background As a major component of plant cell wall, lignin plays important roles in mechanical support, water transport, and stress responses. the main cause for recalcitrance modification has been task bioenergy feedstock improvement. The study evolution function biosynthesis genes thus two-fold implications. First, pathway provides an excellent model to coordinative biochemical plants. Second, understanding will guide us develop better strategies Results We analyzed from fourteen...
Developing drought-resistant alfalfa (Medicago sativa L.) that maintains high biomass yield is a key breeding goal to enhance productivity in water-limited areas. In this study, 424 families were analyzed identify molecular markers associated with under drought stress and predict high-merit plants. Biomass was measured from 18 harvests 2020 2023 field trial deficit irrigation. A total of 131 significant yield, 80 specifically linked stress; among these, 19 multiple harvests. Finally, genomic...
Active breeding programs specifically for root system architecture (RSA) phenotypes remain rare; however, branch and taproot types in the perennial crop alfalfa is ongoing. Phenotyping this other crops active RSA has mostly used visual scoring of specific traits or subjective classification into different types. While image-based methods have been developed, translation to applied limited. This research aimed at developing comparing phenotyping using machine deep learning algorithms...
The low digestibility of fiber in alfalfa (Medicago sativa L.) limits dry matter intake and energy availability ruminant animal production systems. Previously, plants were identified for or high rapid (16 h) potential (96 vitro neutral detergent (IVNDFD) plant stems. Here, two cycles bidirectional selection 16 h 96 IVNDFD carried out. resulting populations evaluated total herbage, percentage stems to biomass, IVNDFD, (NDF), acid lignin as a proportion NDF (ADL/NDF) at three maturity stages....
The nucleotide-binding site-leucine-rich repeat (NBS-LRR)-encoding gene family has attracted much research interest because approximately 75% of the plant disease resistance genes that have been cloned to date are from this family. We NBS-LRR-encoding polyploid cotton by a polymerase chain reaction-based approach. A sample 150 clones was selected NBS-LRR sequence library and sequenced, 61 analogs (RGA) were identified. Sequence analysis revealed RGA abundant highly diverged in genome could...
Abstract Alfalfa is widely recognized as an important forage crop. To understand the morphological characteristics and genetic basis of seed morphology in alfalfa, we screened 318 Medicago spp., including 244 sativa subsp. (alfalfa) 23 other for area size, length, width, length-to-width ratio, perimeter, circularity, distance between intersection length & width (IS) center gravity (CG), darkness red–green–blue (RGB) intensities. The results revealed phenotypic diversity correlations...
Abstract Alfalfa ( Medicago sativa L.), known as the queen of forages, is a versatile and valuable forage crop that holds significant importance in agriculture due to its myriad benefits for livestock. Ruminants benefit from alfalfa's digestible fiber protein, contributing improved feed efficiency milk production. However, alfalfa protein rapidly extensively degraded rumen, it challenge maximize crude utilized metabolizable by ruminant In this study, phenotypic data 14 traits related...
Phosphorus (P) is one of the essential nutrients for alfalfa (Medicago sativa L.) growth, but P deficiency in soil a common phenomenon. Applying an appropriate amount fertilizer establishment year improves winter survival, helps achieve sustainable high yields, and promotes best economic returns. The objective this study was to determine effect different fertilization rates (0, 22, 44, 66 kg ha−1) on forage yield, root traits two late-summer seeded cultivars (dormant semi-dormant) first...
Upland cotton (G. hirsutum L.) is the leading fiber crop worldwide. Genetic improvement of quality and yield facilitated by a variety genomics tools. An integrated genetic physical map needed to better characterize quantitative trait loci allow for positional cloning valuable genes. However, developing genomic tools complex allotetraploid genomes, like that cotton, highly experimental. In this report, we describe an effective approach framework allows distinguishing between subgenomes in...
The root system architecture (RSA) of alfalfa (Medicago sativa L.) affects biomass production by influencing water and nutrient uptake, including nitrogen fixation. Further, roots are important for storing carbohydrates that needed regrowth in spring after each harvest. Previous selection a greater number branched fibrous significantly increased yield. However, phenotyping systems mature plant is labor-intensive, time-consuming, subject to environmental variability human error....
Phytophthora spp. are serious pathogens that threaten numerous cultivated crops, trees, and natural vegetation worldwide. The soybean pathogen P. sojae has been developed as a model oomycete. Here, we report bacterial artificial chromosome (BAC)-based, integrated physical map of the genome. We constructed two BAC libraries, digested 8,681 BACs with seven restriction enzymes, end labeled fragments four dyes, analyzed them capillary electrophoresis. Fifteen data sets were from fingerprints,...
Background: Root system architecture (RSA) is of growing interest in implementing plant improvements with belowground root traits. Modern computing technology applied to images offers new pathways forward trait and selection through RSA analysis (using discern/classify types traits). However, a major stumbling block image-based phenotyping image label noise, which reduces the accuracies models that take as direct inputs. To address noise problem, this study utilized an artificial...
Alfalfa biomass can be fractionated into leaf and stem components. Leaves comprise a protein-rich highly digestible portion of for ruminant animals, while stems constitute high fiber less fraction, representing 50 to 70% the biomass. However, little attention has focused on stem-related traits, which are key aspect in improving nutritional value intake potential alfalfa. This study aimed identify molecular markers associated with four morphological traits panel five populations alfalfa...
Physical mapping with large-insert clones is becoming an active area of genomics research, and capillary electrophoresis (CE) promises to revolutionize the physical technology. Here, we demonstrate utility CE technology for genome by constructing a robust, binary bacterial artificial chromosome (BIBAC)-based map Penicillium chrysogenum. We fingerprinted 23.1x coverage BIBAC five restriction enzymes SNaPshot kit containing four fluorescent-ddNTPs using technology, explored various strategies...
Cotton (Gossypium spp.) is an important crop plant that widely grown to produce both natural textile fibers and cottonseed oil. fibers, the economically more product of cotton plant, are seed trichomes derived from individual cells epidermal layer coat. It has been known for a long time large numbers genes determine development fiber, recently it determined these distributed across At Dt subgenomes tetraploid AD cottons. In present study, organization evolution fiber were investigated...
By incorporating high-density markers into breeding value prediction models, the whole genomic (WGP) method can effectively accelerate genetic improvement in livestock breeding. However, performance of WGP varies across species and populations is affected by underlying architecture. In particular, very little known about for many chicken breeds. Here we estimate parameters evaluate 18 growth carcass traits a Chinese quality population. total, 435 chickens were systematically phenotyped...
