Article Synopsis
  • The study investigates how ecological factors in the rhizosphere affect the decline of sugarcane ratoons, highlighting key elements like soil potassium, nitrogen fixation, and peroxidase activity that promote growth in younger ratoons.
  • Significant differences in microbial community structures were found between different ratoon ages, which correlated with sugarcane growth outcomes.
  • Endophytic fungi, particularly those from the Ascomycota group, appear to influence sugarcane health negatively, suggesting a need for further exploration of these ecological interactions.

Introduction: is a common protective forest in coastal areas. However, artificial forests cannot self-renew, mainly due to the accumulation of allelochemicals. Endophytic bacteria may alleviate the root growth inhibition caused by allelochemicals in seedlings.

The coastal is the most common tree species in Hainan's coastal protection forests. Sequencing the genomes of its allelopathic endophytes can allow the protective effects of these bacteria to be effectively implemented in protected forests. The goal of this study was to sequence the whole genomes of the endophytes and from root tissues.

Allelopathy is a process whereby a plant directly or indirectly promotes or inhibits growth of surrounding plants. Perennial sugarcane root extracts from various years significantly inhibited Bidens pilosa, Digitaria sanguinalis, sugarcane stem seedlings, and sugarcane tissue-cultured seedlings (Pā€‰<ā€‰0.05), with maximum respective allelopathies of -ā€‰0.

Productivity decline of plantation and difficulty in natural regeneration remains a serious problem because of allelopathy. Previous studies have confirmed that 2,4-di-tert-butylphenol (2,4-DTBP) are the major allelochemicals of the litter exudates. The production of these allelochemicals may derive from decomposition of litter or from the litter endophyte and microorganisms adhering to litter surfaces.

Sugarcane ratoon performance declines with increasing age due to the intergenerational accumulation and release of allelochemicals by old sugarcane roots. We aimed to clarify the effects of these allelochemicals on sugarcane seedling growth under continuous sugarcane ratoon cropping. We investigated the allelopathic effects of treatment with root aqueous extracts from sugarcane ratoons of different ages on the osmoregulatory substance content, antioxidant enzyme activity, membrane lipid peroxidation product content, photosynthetic physiological characteristics, and root exudate enzymatic characteristics of sugarcane seedlings.

Litter plays an important role in ecosystems. To compare the diversity and community structure of microorganisms inside and outside litter, were selected from three forests in Guilin coastal area of Haikou City, Hainan Province. Illumina Miseq high-throughput sequencing was used to analyze the diversity and composition of epiphytic and endophytic bacteria of litter.

Background: Casuarina equisetifolia is one of the most important artificially planted protective forests along the coast in southern China for windbreaks, soil erosion, and sand dune stabilization. Self-renewing of C. equisetifolia is very limited, which might be caused by low soil nutrient levels and reduced microbial activity.
