Exogenous application of melatonin to mitigate drought stress-induced oxidative damage in seedlings.

Background: Drought stress is a major prevalent environmental factor impairing growth. Melatonin mitigates the impacts of drought stress on plants. However, melatonin's role in () is unknown.

The Role of in the Lobed Leaf Formation of var. .

A lobed leaf is a common trait in plants, but it is very rare in Lauraceae plants, including species of In the study of germplasm resources of , we found lobed leaf variant seedlings, and the variation could be inherited stably. Studying the lobed leaf mechanism of var. can offer insight into the leaf development mechanism of woody plants.

Comparative Transcriptome Analysis Revealing the Potential Mechanism of Low-Temperature Stress in .

is a rare national tree species in China and possesses important ornamental and ecological value. can be planted in low-temperature areas, depending on whether its seedlings can withstand the harm. To face this problem, the annual seedlings of were subjected to five temperature treatments, and eight physiological indicators were measured.

Characteristics of tree growth in mountain areas of central China: insights from isotopic compositions and satellite-derived indices.

Leaf nitrogen (N) status and stable isotope ratios of carbon (C) and nitrogen (N) were used to study environmental factors that control mountain individuals of trees, a coniferous species endemic and endangered in China. From May to September 2016, we carried out observations at four different altitude locations extending southeast of Daba Mountain in western Hubei Province. Needle-shaped leaf C was positively correlated with needle N and C content calculated from the needle area (N and C content), needle N, needle mass, and leaf mass per area (LMA), respectively.

Differential Expression of MicroRNAs During Root Formation in Var. Cultivars.

MicroRNAs (miRNAs) have been shown to play key roles in the regulation of plant growth and development by modifying the expression of their target genes. However, the influence of miRNAs on root formation and development in woody plants, such as , remains largely unknown. In the current study, we explored the phytohormone-response and nutrition-response miRNA expression profiles during rooting by quantitative real-time PCR (qPCR).

Biological significance of RNA editing in cells.

RNA editing is one of the post-transcriptional RNA processes. RNA editing generates RNA and protein diversity in eukaryotes and results in specific amino acid substitutions, deletions, and changes in gene expression levels. Adenosine-to-inosine RNA editing represents the most important class of editing in human and affects function of many genes.
