“…Additionally, root growth cessation via ethylene and auxin rapidly occurred; and this quiescence behavior contributed to enhance hypoxia tolerance [ 42 ]. On the other hand, out of four auxins, which are indole-3-acetic acid, indole-3-propionic acid, indole-3-butyric acid, and 1-naphthylacetic acid, treatment with indole-3-butyric acid resulted in a high rooting rate and beneficial root morphology [ 43 ]. Additionally, 1.5 mg/L indole-3-butyric acid exhibited the highest rooting responses and 1.0 mg/L indole-3-butyric acid improved fruit yield and biomass [ 44 ].…”

Flooding impairs wheat growth and considerably affects yield productivity worldwide. On the other hand, irradiation with millimeter waves enhanced the growth of chickpea and soybean under flooding stress. In the current work, millimeter-wave irradiation notably enhanced wheat growth, even under flooding stress. To explore the protective mechanisms of millimeter-wave irradiation on wheat under flooding, quantitative proteomics was performed. According to functional categorization, proteins whose abundances were changed significantly with and without irradiation under flooding stress were correlated to glycolysis, reactive-oxygen species scavenging, cell organization, and hormonal metabolism. Immunoblot analysis confirmed that fructose-bisphosphate aldolase and β tubulin accumulated in root and leaf under flooding; however, even in such condition, their accumulations were recovered to the control level in irradiated wheat. The abundance of ascorbate peroxidase increased in leaf under flooding and recovered to the control level in irradiated wheat. Because the abundance of auxin-related proteins changed with millimeter-wave irradiation, auxin was applied to wheat under flooding, resulting in the application of auxin improving its growth, even in such condition. These results suggest that millimeter-wave irradiation on wheat seeds improves the recovery of plant growth from flooding via the regulation of glycolysis, reactive-oxygen species scavenging, and cell organization. Additionally, millimeter-wave irradiation could promote tolerance against flooding through the regulation of auxin contents in wheat.

Triploid lacquer trees have a higher yield of raw lacquer and greater stress resistance, however, it is challenging to develop efficient and rapid seedling culture techniques because of the influence of metabolites with raw lacquer. In this study, the stem segments of a triploid lacquer tree were used to investigate the effects of explant sterilization treatment, different combinations of exogenous hormone concentrations on the induction of axillary buds, seedling development, and rooting, as well as transplanting substrate ratios. The results showed that the optimal combination of disinfection treatment for triploid Toxicodendron vernicifluum explants involves 75% alcohol immersion for 10 s, followed by 2.0% benzalkonium chloride treatment for 1 min, and 0.1% HgCl2 treatment for 4 min. The suitable medium for axillary bud induction was Murashige and Skoog’s (MS) + 0.1 mg/L zeatin (ZT) + 0.1 mg/L 6-benzylaminopurine (6-BA), resulting in a high induction rate of 95.00%. The combination of 1/2 MS + 0.5 mg/L 6-BA + 0.3 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) was the most effective for axillary bud proliferation. The combination of 1/2 MS + 0.1 mg/L 6-BA + 0.5 mg/L 2,4-D + 0.5 mg/L indole-3-butyric acid (IBA) + 0.2% activated carbon (AC) was an optimum for hardening-off. With Woody Plant Medium (WPM) + 0.5 mg/L naphthaleneacetic acid (NAA) + 0.5 mg/L 2,4-D + 0.5 g/L AC as rooting medium, the rooting rate was 67.76%. Also, the appropriate transplanting substrate ratio for triploid T. vernicifluum was grass charcoal: laterite: humus =1: 1: 1. Collectively, our results provide the technical assurance for seedling scale multiplication and propagation, facilitating its application in production.

“…Plant growth regulators play an important role in regulating the physiological structure, growth, development and morphogenesis in plant tissue culture. Therefore, it is the basis of plant tissue culture to study the appropriate hormone types and concentrations in plant regeneration [ 30 , 31 ]. Forchlorfenuron (CPPU) and 2-isopentenyladenine (2iP) play a key role in callus induction and regeneration in plants [ 32 , 33 , 34 , 35 ].…”

The main propagation approach is tissue culture in blueberries, and tissue culture is an effective and low-cost method with higher economic efficiency in blueberries. However, there is a lack of stable and efficient production systems of industrialization of tissue culture in blueberries. In this study, the high-efficiency tissue culture and rapid propagation technology system were established based on blueberry leaves and stems. The optimal medium for callus induction was WPM (woody plant medium) containing 2.0 mg/L Forchlorfenuron (CPPU), 0.2 mg/L 2-isopentenyladenine (2-ip) with a 97% callus induction rate and a callus differentiation rate of 71% by using blueberry leaves as explants. The optimal secondary culture of the leaf callus medium was WPM containing 3.0 mg/L CPPU with an increment coefficient of 24%. The optimal bud growth medium was WPM containing 1.0 mg/L CPPU, 0.4 mg/L 2-ip, with which the growth of the bud was better, stronger and faster. The optimal rooting medium was 1/2 Murashige and Skoog (1/2MS) medium containing 2.0 mg/L naphthylacetic acid (NAA), with which the rooting rate was 90% with shorter rooting time and more adventitious root. In addition, we established a regeneration system based on blueberry stems. The optimal preculture medium in blueberry stem explants was MS medium containing 2-(N-morpholino) ethanesulfonic acid (MES) containing 0.2 mg/L indole-3-acetic acid (IAA), 0.1 mg/L CPPU, 100 mg/L NaCl, with which the germination rate of the bud was 93%. The optimal medium for fast plant growth was MS medium containing MES containing 0.4 mg/L zeatin (ZT), 1 mg/L putrescine, 1 mg/L spermidine, 1 mg/L spermidine, which had a good growth state and growth rate. The optimal cultivation for plantlet growth was MS medium containing MES containing 0.5 mg/L isopentene adenine, with which the plantlet was strong. The optimal rooting medium for the stem was 1/2MS medium containing 2.0 mg/L NAA, with which the rooting rate was 93% with a short time and more adventitious root. In conclusion, we found that stem explants had higher regeneration efficiency for a stable and efficient production system of industrialization of tissue culture. This study provides theoretical guidance and technical support in precision breeding and standardization and industrialization in the blueberry industry.
