Abstract A DNA barcode is a fragment used to identify species. For land plants, fragments of plastid genome could be the primary consideration. Unfortunately, most candidate barcodes lack species-level resolution. The identification high resolution at species level critical success barcoding in plants. We searched available genomes for variable regions and tested best candidates using both large number tree seven well-sampled plant groups. Two gene ycf1 , b, were loci that better than...

Metformin plays an important role in diabetes treatment. Studies have shown that the combined use of oral hypoglycemic medications is more effective than metformin monotherapy. In this double-blind, randomized, placebo-controlled, multicenter trial, we evaluated whether Jinlida, a Chinese herbal medicine, enhances glycemic control type 2 patients whose HbA1c was ineffectively controlled with alone.

Ophiopogon bodinieri H.Lév. (Asparagaceae) is a perennial flowering herbaceous plant native to China, and widely cultivated as ornamental in South China. During May 2024, an anthracnose was observed on approximately 70% of O. farm at Mazhang, Zhanjiang, Guangdong Province (22°6′14.7′′N,110°27′26.8′′E). The symptoms appeared first small spots with irregular yellow or brown halos, subsequently, the lesions darkened expanded, covering leaves. Twenty four plants infected disease were sampled,...

Schistosomiasis japonica is a serious debilitating and sometimes fatal disease. Accurate diagnostic tests play key role in patient management control of the However, currently available methods are not ideal, detection parasite DNA blood samples has turned out to be one most promising tools for diagnosis schistosomiasis. In our previous investigations, 230-bp sequence from highly repetitive retrotransposon SjR2 was identified it showed high sensitivity specificity detecting Schistosoma...

Branch development in the lower part of stem is critical to both early growth and wood quality most valuable section tree, its regulation through planting density has always been greatly concerned. Here effect on branch was examined a five-year-old plantation Betula alnoides with six densities (625, 833, 1111, 1250, 1667, 2500 stems per hectare (sph)) Guangdong Province, South China. quantity (number, proportion, density), morphology (diameter, length, angle), position (height orientation),...

Both crown and branch characteristics greatly affect tree growth timber quality, their development is closely related to planting density (PD). Here attributes of Betula alnoides were investigated in a 14-year-old experimental plantation southern China with five densities ranging from 500 3333 stems per hectare (sph). The results showed that high PD significantly reduced sizes. ratios diameter stem at breast height the stand level for dominant co-dominant trees almost constant regardless PD....

Betula alnoides is a valuable timber species with wide ecological adaptability in Southeast Asia and southern China. There are more than 150,000 ha of B. plantations China until now. However, heavy differentiation growth quality traits low productivity usually seen the practice. Elite germplasm thus urgently needed for this species. Here 199 families 25 provenances were assessed at four sites when 10–15 years old to estimate genetic parameters reveal genotype by environment (G × E)...

Erythrophleum fordii Oliv. is a valuable rosewood species indigenous to the tropical and warm sub-tropical zones of Vietnam, Laos, South China. The natural forests have been heavily fragmented mostly due over-exploitation over-utilization, alteration croplands fast-growing plantations. Therefore, it has included in IUCN Red List Endangered Species as an endangered species.

Abstract Next generation sequencing (NGS) technologies play a powerful role in the preparation of large DNA databases such as barcoding since it can produce number sequence reads. Here we demonstrate primer-induced sample labeling method aiming at samples simultaneously on NGS platforms. The strategy is to label with unique oligo attached 5′-ends primers. As case study, 894 pentanucleotide oligoes were three pairs primers (for amplifying ITS, mat K and rbc L) samples. All PCR products...

Betula alnoides is an ecologically and economically important species in the tropics warm subtropics. Nineteen polymorphic microsatellite markers were isolated from this species, which displayed three to 12 alleles per locus. The observed heterozygosities ranged 0.100 0.905, expected 0.510 0.893. These would be useful tools genetic resource assessment, molecular marker-assistant breeding, parentage analysis diversity studies for species.

Bacterium-like particles (BLPs) have gained significant attention in vaccine development due to their potential as effective immune enhancers and antigen delivery systems. BLPs are generated by boiling lactic acid bacteria an acidic solution devoid of proteins nucleic acids, offering advantages terms ease preparation, high safety, good stability. Furthermore, employing protein anchor (PA), heterogeneous antigens can be efficiently displayed on the surface BLPs, resulting enhanced...
