“…Different letters within each row indicate significant differences (P ≤ 0.05) according to the LSD test. Stresses increase the production of ROS, and the accumulation of MDA is often used as an indicator of lipid peroxidation (Liu et al 2013). The present study shows that the cold stress significantly elevated the MDA content and O 2 .production rate relative to the control (Table 1).…”

This study was carried out to understand the mechanism of protection of plants under cold stress by exogenous 24-epibrassinolide (EBR). The eggplant (Solanum melongena L.) seedlings were pretreated with five concentrations of EBR (0, 0.05, 0.1, 0.2 and 0.4 µM) and then exposed to day/night temperatures of 10/5 °C for 8 d. The results show that EBR, especially 0.1 µM EBR, dramatically alleviated growth suppression and a decrease in chlorophyll content and photosynthetic rate caused by the cold stress. In addition, EBR also decreased malondialdehyde content and O 2.production rate induced by the cold stress, and increased the activities of superoxide dismutase, guaiacol peroxidase, catalase, and ascorbate peroxidase, and proline content. The results of the present study suggest that exogenous EBR could improve cold tolerance of eggplant by regulating photosynthesis and antioxidative systems.

“…Proline is one of the most important organic osmolytes in plant cells and is rapidly accumulated in plants after cold stress (Liu et al, 2009;Liu et al, 2013). Glutamic acid can act as the precursor of proline (Munns, 2005;Sharma and Dietz, 2006).…”

This study aimed to determine the effects of foliar application of glutamic acid to alleviate the physiological damage caused by low air temperatures at early growth stages in Kimchi cabbages. Twenty-eight days after transplanting the Kimchi cabbage was exposed to a low (10°C) air temperature for seven days and then treated with three different foliar sprays including pure water (control), 0.3% urea, and 10 µmol•mol-1 glutamic acid solutions (GA). After foliar treatments, cabbage plants were grown in non-shaded or 30%-shaded conditions. The maximum fresh weight of Kimchi cabbage was 1,700 g/plant when treated with glutamic acid, and the minimum fresh weight was 1,193 g/plant when treated with urea. Both head weight and yield were the greatest with glutamic acid treatment, which produced 4,845 kg/10a, while urea treatment produced only 3,400 kg/10a. The net photosynthetic rate and stomatal conductance were greatest under both glutamic acid and urea treatments compared to pure water. Low air temperature treatment of Kimchi cabbages adversely affected the net photosynthetic rate and stomatal conductance; however, an increase in the carboxylation rate and photosynthetic electron transport system efficiency was also observed. GA treatment reduced enzymatic activity in cold conditions compared to control plants that weren't treated. Notably, the H 2 O 2 level was the lowest after glutamic acid treatment. These results indicated that foliar application of glutamic acid reduced physiological damage and enhanced antioxidant enzymes activity in Kimchi cabbages, which improved their tolerance to low air temperature.

“…Plant flowering is affected by many factors, among which temperature and light play essential roles [ 9 ]. Vernalization pathways are extensive flowering pathways in crucifers, whose flowering requires a low temperature [ 20 ]. Nevertheless, temperature is not the only factor that affects the flowering of crucifers.…”

“…Chinese cabbages and turnips are mostly late-flowering types that need long-term vernalization to promote flowering. A low temperature is needed for the flowering of NHCC, whose budding, bolting, and flowering time are affected by the site, temperature, and time of vernalization treatment [ 20 ]. Previous studies have mainly focused on the molecular mechanism of genes during bolting and flowering in NHCC.…”

“…Previous studies have mainly focused on the molecular mechanism of genes during bolting and flowering in NHCC. Researchers have confirmed that MAF , TEM , and FLC family genes play important roles in regulating NHCC bolting and flowering [ 20 , 21 , 22 ]. In addition, the bolting and flowering of NHCC is not only regulated by the vernalization pathway but is also affected by other factors.…”

Flowering time is an important agronomic trait in Brassica rapa and has a wide range of variation. The change from vegetative to reproductive development is a major transition period, especially in flowering vegetable crops. In this study, two non-heading Chinese cabbage varieties with significantly different flowering times, Pak-choi (B. rapa var. communis Tesn et Lee) and Caitai (B. rapa var. tsaitai Hort.), were used to construct segregated F2 populations. The bulk-segregant approach coupled with whole genome re-sequencing was used for QTL sequencing (QTL-seq) analysis to map flowering time traits. The candidate genes controlling flowering time in B. rapa were predicted by homologous gene alignment and function annotation. The major-effect QTL ft7.1 was detected on chromosome A07 of B. rapa, and the FT family gene BrFT was predicted as the candidate gene. Moreover, a new promoter regional difference of 1577 bp was revealed by analyzing the sequence of the BrFT gene. The promoter region activity analysis and divergent gene expression levels indicated that the difference in the promoter region may contribute to different flowering times. These findings provide insights into the mechanisms underlying the flowering time in Brassica and the candidate genes regulating flowering in production.
