Description
Technical Field
The invention relates to the field of plant genetic engineering and molecular breeding, in particular to application of a tomato gene SlMAPK12 in regulation and control of tomato drought resistance.
Background
Tomatoes are the second most consumed vegetables in the world and play an important role in world agricultural production. The abiotic stress caused by global water resource shortage, extreme climate and salinization of soil in facility cultivation seriously affects tomato growth, fruit quality and yield. 1/3 of land in China belongs to arid or semi-arid regions, and loss caused by drought to agricultural production is the first of all abiotic stresses. At present, key genes for regulating and controlling the tomato drought stress are less involved. Mitogen-activated protein kinases (MAPKs), a serine/threonine (Ser/Thr) protein kinase. MAPK is one of important components in the process of converting extracellular stimulation signals into intracellular reaction by eukaryotic cells, plays an important role in the processes of transmitting and amplifying signals, and participates in the regulation of plant growth and development and various signal transduction pathways responding to adversity stress.
According to the research in recent years, MAPK cascade reaction participates in a series of abiotic stresses such as plant response drought, low temperature, high salt and the like, for example, arabidopsis MKK2 plays an important pivotal role in cold damage and salt stress, and biochemical and genetic analysis can obtain: MKK2 is used to control the expression of 152 genes to raise saline and low temperature resistance. When a plant is under stress of adverse conditions such as drought, high salt, high temperature, low temperature and the like, a Reactive Oxygen Species (ROS) system of the plant is easily damaged, so that a large amount of ROS is generated and accumulated, oxidative stress damage is induced, plant cell membranes and cell organelles are further damaged, intracellular ions and organic matters are caused to seep, and finally a series of physiological and biochemical processes in the plant body are out of control, and even the plant is dead. The ROS scavenging system in plants is mainly divided into enzyme substances and non-enzyme substances, wherein the enzyme substances include Superoxide Dismutase (SOD), catalase (CATase, CAT), ascorbate Peroxidase (APX), peroxidase (POD), and the non-enzyme substances include Ascorbic Acid (Ascorbic Acid, asA), reduced Glutathione (GSH), etc. Many studies have shown that ROS production, an increase in antioxidant capacity, is often accompanied by MAPK activation.

3. Results and analysis
3.1 plant phenotype after Abiotic stress
The tomato plant has obvious phenotype in a drought stress test, obvious plant phenotype difference and a series of related indexes (figure 1) are obtained when the tomato plant is drought at 9d and 12d, and the function of SlMAPK12 in regulating the plant drought resistance is analyzed. After drought stress was completed and rehydrated, the survival rates were 95.6% and 97.7% for the wild type and the intervention type, respectively, while the over-expression type was 88.9%.
3.2 Effect of drought stress on reactive oxygen levels
Under drought stress, a large amount of ROS is accumulated in tomatoes to induce membrane lipid to generate a peroxidation process, and nucleic acid and protein in cells are directly attacked, so that the phenomena of nucleic acid structure damage, protein polymerization, polypeptide chain breakage, enzyme protein inactivation and the like are caused. Wild Type (WT), overexpression (M12G) and intervention (35 s-12 i) types of H under drought stress by DAB/NBT staining 2 O 2 Content and O 2 · - The content was qualitatively determined.
In FIG. 2A and B are DAB and NBT, respectively, vs. H in tomato leaves 2 O 2 Content and O 2 · - Qualitative content detection, the darker the color, the more H accumulated in the leaf 2 O 2 Content and O 2 · - The more the content. As can be seen from A in FIG. 2, as the drought stress time increases, the color of the leaves of the SlMAPK12 overexpression tomato plants is obviously darker than that of wild and interference plants after the leaves are treated, and no obvious difference exists between the leaves of the wild type and the interference type. Indicating that the overexpression type leaves accumulate H under the drought condition 2 O 2 More, perhaps the ROS scavenging system is disrupted. As can be seen from B in FIG. 2, as the drought stress time increases, leaf depth of the wild type, overexpression type and intervention type tomatoes increases significantly, but the overexpression type increases significantly more than the wild type, and the intervention type increases less than the wild type. Indicating overexpression type leaf O under drought conditions 2 · - Highest content, while SlMAPK12 interference type leaves accumulate O 2 · - Is obviously lower than the wild type and the over-expression type.
3.3 Effect of drought stress on leaf malondialdehyde and relative conductivity
Malondialdehyde (MDA) is one of the most important products of membrane lipid peroxidation, which can exacerbate membrane damage. Therefore, the MDA content is a common index in the research of plant aging physiology and resistance physiology, and the degree of membrane lipid peroxidation can be known through MDA. And detecting the damage degree of the membrane system and the drought resistance of the plant by adopting an indirect method. As shown in FIG. 3A, there was a different increase in MDA content in the leaves of each type of tomato with increasing duration of drought stress. When drought stress occurs for 9 days, the MDA content in the over-expressed tomato leaves is increased by 104.20 percent compared with that in the untreated tomato leaves, and the wild type and the interference type are respectively increased by 42.00 percent and 55.88 percent, which shows that the drought resistance of the over-expressed tomato leaves is obviously weaker than that of the wild type and the interference type.
When the plant is stressed by adversity, the permeability of cell membranes can be increased to different degrees, and the exosmosis of intracellular electrolytes is caused. Relative conductivity is an important indicator for measuring cell membrane stability. As shown in fig. 3B, after 12 days of drought stress, the relative conductivity of over-expressed tomato leaves increased 162.69% compared to untreated leaves, and wild-type over-expression and intervention types increased 153.64% and 98.46%, respectively, indicating that the intervention type maintained cell membrane stability and integrity well under drought conditions. Under drought stress, the change trend of the relative conductivity is similar to that of MDA, but the difference is that the MDA of the tomatoes rises by 9 days of the drought stress, and the rising amplitude of the MDA is obviously larger than that of the relative conductivity.
3.4 Effect of drought stress on leaf proline and soluble sugar content
Proline and soluble sugar in tomato leaves belong to soluble osmotic regulatory substances, and can help plants regulate cell osmotic pressure and maintain cell membrane integrity under adversity stress, so that the adaptability of the plants to the adversity stress is improved.
It can be seen from a in fig. 4 that at 9 days of drought stress, proline in the wild type, overexpressed and interfered with three types of plants showed a significant increase, 5.21-fold, 12.18-fold and 12.94-fold respectively, compared to untreated ones, and remained rising continuously until 12 days of drought stress. And combining the MDA in 3.3 and the measurement result of the relative conductivity, the drought resistance of the over-expressed tomato plant is the weakest. As can be seen from B in FIG. 4, the soluble sugar content in the tomato leaves increased significantly under drought stress, and increased with the increase of the treatment time. After 12 days of drought stress, the soluble sugar content of the over-expressed tomato leaves was increased by 225.54% compared to the untreated tomato leaves, and the wild type and the intervention type were increased by 160.52% and 169.43%, respectively. There is some difference in the change rule of proline and soluble sugar, which indicates that there may be difference in the proline and sugar metabolism of different types of tomato.
3.5 Effect of drought stress on leaf antioxidant enzyme Activity
Abiotic stress can cause a large amount of ROS to be accumulated in plants, severe damage is caused to various cell structures, and in order to maintain the dynamic balance of in vivo oxidation reduction, the plants form a set of efficient antioxidant enzyme system to remove excessive active oxygen in time. SOD, CAT, APX, POD, MDHAR and the like are included in the ROS scavenging system of plants.
The invention detects the activities of SOD, CAT, APX and POD in the tomato leaves under drought stress. As can be seen from FIG. 5, SOD and CAT activities were substantially increased in tomato leaves under drought stress, in which SOD activities of wild, overexpressed and interfered types were increased by 43.02%, 27.78% and 58.05% respectively at 12 days of stress as compared to those without treatment, and CAT activities were increased by 57.76%, 37.65% and 43.55% respectively. In 12 days of drought, the SOD activity of the over-expressed plants is obviously higher than that of wild plants, and the SOD activity of the interference plants is obviously higher than that of wild plants. The POD activity was increased by 45.65%, 47.45% and 37.56% for the wild type, the overexpression type and the interference type, respectively, at 12 days of drought stress, and the interference type was significantly higher than the wild type at 9 days of drought stress.
During the whole drought stress process, the APX activity of the three types of tomato material does not show regular changes. After drought stress treatment, the APX activity of wild type and over-expression type tomato plants is improved by 27.27 percent and 74.29 percent respectively, while the APX activity of interference type tomato plants is reduced by 37.82 percent.
3.6 Effect of drought stress on leaves PS II
As shown in FIG. 6, the maximum light quantum efficiency (Fv/Fm) of the wild type, the overexpression type and the interference type are substantially consistent under drought stress, and are respectively reduced by 15.24%, 11.47% and 12.00% when the drought stress is carried out for 12 days. Quantum efficiency of photosynthetic electron transfer in PS II) In the curve of change, of the respective treatment materialThe curve shows a trend of increasing and then decreasing, and under drought stress, slMAPK12 has little or no effect on PS II.
