As a reducing substance, ascorbic acid functioned well in abiotic and biotic stress. However, the regulatory mechanism of drought resistance is rarely known in pak choi. Here we found a gene containing a C2 domain that responds to ABA signal and drought regulation in pak choi.

Several stresses trigger the accumulation of ethylene, which then transmits the signal to ethylene response factors (ERFs) to participate in the regulation of plant development to adapt to the environment. This study clarifies the function of BcERF98, a homolog of AtERF98, in the regulation of plant flowering time mediated by high concentrations of ethylene.

Melatonin (MT) has been found to be a bioactive compound that can mitigate these adverse effects, which makes it necessary to understand the function of MT and its role in salt stress. During this study, plants were treated exogenously with 100 µM of MT for 7 days and subjected to 200 mM of salt stress, and samples were collected after 1 and 7 days for different indicators and transcriptome analysis.

Ethylene responsive factor 070 (BcERF070) is important in flowering. However, the underlying molecular mechanisms of BcERF070 in floral transition in response to ethylene signaling have not been fully characterized.

However, limited information is available on the mechanism of sesquiterpene formation and composition in the non-heading Chinese cabbage (NHCC) leaf. Therefore, headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS) combined with transcriptome analysis was used to study the mechanism of volatile organic compound formation.

Copper is a mineral element, which is necessary for the normal growth and development of plants, but high levels of copper will seriously damage plants. Studies have shown that improves the tolerance of to aluminum and cadmium stress. However, the role of in the copper stress response of plants is still unclear.
View Article and Find Full Text PDFThirty-five IQD genes were identified and analysed in Chinese cabbage and BrIQD5 transgenic plants enhanced the drought resistance of plants. The IQD (IQ67-domain) family plays an important role in various abiotic stress responses in plant species. However, the roles of IQD genes in the Chinese cabbage response to abiotic stress remain unclear.
