Continuous cropping in greenhouses can result in root-knot nematode outbreaks resulting from imbalances in the soil nematode community. However, the changes in soil nematode communities in greenhouses with continuous crop production are unclear. We compared soil nematode communities in greenhouses after 2 years (2-yr) and 10 years (10-yr) of continuous crop production by 18S rDNA high-throughput sequencing

The local auxin distribution characteristics in the roots, stems, and leaves of stably transformed plantlets of trifoliate orange (Poncirus trifoliata) with auxin reporter system DR5::GUS-YFP were elucidated in this research. The auxin response maxima could be observed in the apex of the root tip, primary phloem of the tender stem, and the margin of the young leaves according to the activity of the

Anthocyanins are the most widely produced secondary metabolites in plants, and they play an important role in plant growth and reproduction. The nitrogen source is an important factor affecting anthocyanin production, but the nitrogen concentrations on metabolism and the underlying genetic basis remain unclear. In this study, in vitro anthocyanin induction was conducted on Malus spectabilis. The leaf

Melatonin, as a plant growth regulator, is involved in plant stress resistance. We studied the effects of different concentrations (0, 10, 50, 100, 150, and 200 µmol · L−1) of melatonin on the growth and physiological characteristics of strawberry under cadmium (Cd) stress. The results represented that the growth of strawberry seedlings was inhibited under Cd stress, and the seedling biomass, chlorophyll

As an important horticultural plant, the orchid is widely distributed in its natural habitat and faces various environmental stresses, among which nutrient recycling and stress resistance are of great concern. During these processes, autophagy is an essential pathway, which is a conserved self-eating process that degrades macromolecular components and recycles cell materials or nutrients during developmental

Brassica rapa is one of the most important leafy vegetable crops with large cultivated area in China. To increase the availability of DNA markers in B. rapa, we developed insertion-deletion (InDel) markers utilizing high-resolution melting (HRM) curve analysis. We designed primers for 252 InDels (≥ 3 bp) evenly distributed in the genome and tested gene polymorphisms with eight accessions. In total

Meiotic recombination and the resulting novel allele combinations are fundamental to plant breeding and the identification of superior hybrids. However, the rate of meiotic crossovers is naturally suppressed below its potential ability, which prevents plant breeding efficiency. Nine suppressors of meiotic recombination have been identified in the model plant Arabidopsis and in other crop species. Mutations

Self-incompatibility (SI), which has recurred during the evolution of plants, is one of the most important cross-pollination mating systems. Three S-loci have been reported in Brassicaceae, namely, Arabidopsis lyrata (Al), Brassica (Br), and Leavenworthia alabamica (La) S-loci. Here, through multi-genomic comparative analysis of 20 species, we revealed that the most ancient S-locus was formed prior
