Insights into the Superrosids phylogeny and flavonoid synthesis from the telomere-to-telomere gap-free genome assembly of Pursh.

The completion of the first telomere-to-telomere (T2T) genome assembly of Pursh (PC), a prominent medicinal plant in China, represents a significant achievement. This assembly spans a length of 257.5 Mb and consists of nine chromosomes.

Mapping of QTLs and Screening Candidate Genes Associated with the Ability of Sugarcane Tillering and Ratooning.

The processes of sugarcane tillering and ratooning, which directly affect the yield of plant cane and ratoon, are of vital importance to the population establishment and the effective stalk number per unit area. In the present study, the phenotypic data of 285 F progenies from a cross of sugarcane varieties YT93-159 × ROC22 were collected in eight environments, which consisted of plant cane and ratoon cultivated in three different ecological sites. The broad sense heritability () of the tillering and the ratoon sprouting was 0.

Screening of Candidate Genes Associated with Brown Stripe Resistance in Sugarcane via BSR-seq Analysis.

Sugarcane brown stripe (SBS), caused by the fungal pathogen , is one of the most serious threats to sugarcane production. However, its outbreaks and epidemics require suitable climatic conditions, resulting in the inefficient improvement of the SBS resistance by phenotype selection. The sugarcane F population of SBS-resistant YT93-159 × SBS-susceptible ROC22 was used for constructing the bulks.

The First Telomere-to-Telomere Chromosome-Level Genome Assembly of Causing Sugarcane Leaf Blight.

The sexual morph Yen and Chi and its asexual morph W. H. Hsieh is an important necrotrophic fungal phytopathogen, which causes sugarcane leaf blight, resulting in loss of cane tonnage and sucrose in susceptible sugarcane varieties.

Sugarcane Confers Drought Stress Tolerance in Transgenic by Regulating the ABA Signal, ROS Level and Stress-Related Gene Expression.

The dehydration-responsive element-binding protein (DREB) is a subgroup member of the AP2/ERF family and actively participates in the response of plants to abiotic stress. Although genes have been studied in a variety of plant species, there are few reports of genes in sugarcane ( spp.).

Genome-Wide Identification of LRR-RLK Family in and Expression Analysis in Response to Biotic and Abiotic Stress.

The leucine-rich repeat receptor-like protein kinase (LRR-RLK) gene family is the largest family of the receptor-like protein kinases (RLKs) superfamily in higher plants, which is involved in regulating the plant growth and development, stress responses, signal transduction and so on. However, no comprehensive analyses of LRR-RLKs have been reported in sugarcane. Here, we performed a comprehensive analysis of the LRR-RLK gene family in sugarcane ancestor species .

Sugarcane Ratooning Ability: Research Status, Shortcomings, and Prospects.

Sugarcane is an important sugar crop and it can be subjected to ratooning for several years. The advantages of ratooning include quality improvement, efficiency enhancement, and reduced costs and energy use. The genotype, environment, cultivation management, and harvesting technology affect the productivity and longevity of ratoon cane, with the genetic basis being the most critical factor.

Sugarcane Mosaic Disease: Characteristics, Identification and Control.

Mosaic is one of the most important sugarcane diseases, caused by single or compound infection of (SCMV), (SrMV), and/or (SCSMV). The compound infection of mosaic has become increasingly serious in the last few years. The disease directly affects the photosynthesis and growth of sugarcane, leading to a significant decrease in cane yield and sucrose content, and thus serious economic losses.

Genome-Wide Characterization of Lectin Receptor Kinases in L. and Their Responses to Infection.

Sugarcane is an important sugar and bioenergy ethanol crop, and the hyperploidy has led to stagnant progress in sugarcane genome decipherment, which also hindered the genome-wide analyses of versatile lectin receptor kinases (LecRKs). The published genome of , one of the two sugarcane ancestor species, enables us to study the characterization of LecRKs and their responses to sugarcane leaf blight (SLB) triggered by . A total of 429 allelic and non-allelic LecRKs, which were classified into evolved independently three types according to signal domains and phylogeny, were identified based on the genome.

ScAOC1, an allene oxide cyclase gene, confers defense response to biotic and abiotic stresses in sugarcane.

An allene oxide cyclase gene which is involved in defense against biotic and abiotic stresses was cloned and characterized in sugarcane. Allene oxide cyclase (AOC), a key enzyme in jasmonate acid (JA) biosynthesis, affects the stereoisomerism and biological activity of JA molecules, and plays an important role in plant stress resistance. In this study, four SsAOC alleles (SsAOC1-SsAOC4), which shared similar gene structure and were located on Chr1A, Chr1B, Chr1C, and Chr1D, respectively, were mined from sugarcane wild species Saccharum spontaneum, and a homologous gene ScAOC1 (GenBank Accession Number: MK674849) was cloned from sugarcane hybrid variety Yacheng05-179 inoculated with Sporisorium scitamineum for 48 h.

miRNA alteration is an important mechanism in sugarcane response to low-temperature environment.

Background: Cold is a major abiotic stress limiting the production of tropical and subtropical crops in new production areas. Sugarcane (Saccharum spp.) originates from the tropics but is cultivated primarily in the sub-tropics where it frequently encounters cold stress.
