Description

Application of 1Dx2m1/2/3 protein and coding gene thereof in cultivation of wheat variety with improved processing quality
Technical Field
The invention belongs to the technical field of biology, and particularly relates to an application of 1Dx2m1/2/3 protein and a coding gene thereof in cultivation of a wheat variety with improved processing quality.
Background
Common wheat (Triticum aestivum l., AABBDD, 2n ═ 6x ═ 42) belongs to the gramineous (Poaceae) wheat (Triticum) genus, and is the most important food crop for human beings. Because the wheat dough has unique elasticity and ductility, the wheat dough can be processed into various foods such as bread, biscuits, noodles, steamed bread, dumplings, fried bread sticks and the like through the processes of baking, cooking, frying and the like. The quality of the food is closely related to the quality of the wheat. Wheat quality refers to the degree to which a wheat variety adapts and meets a particular end use and can be divided into nutritional quality and processing quality. The nutritional quality refers to the degree of satisfaction of nutritional ingredients contained in wheat to human (livestock) nutritional needs, including the amount of nutritional ingredients, whether the nutritional ingredients are balanced, the content of protein, the composition of amino acids, and the like. The processing quality is divided into primary processing quality and secondary processing quality. The quality of primary processing is also called grinding quality, and mainly comprises flour yield, flour color, ash content and the like. The secondary processing quality, also called eating quality, refers to the degree of adaptation and satisfaction of wheat flour to the preparation of different foods, and is mainly related to the physicochemical properties of the dough. The edible quality parameters are many and mainly comprise gluten content, sedimentation value, forming time, stabilizing time, resistance to elongation, stretching area and specific indexes aiming at various baked, steamed and fried wheaten foods.
Currently, the quality improvement of wheat is mainly focused on the processing quality, and is also mainly focused on the baking quality of industrially processed bread, biscuits, cakes and the like, and the baking quality mainly depends on the gluten content and quality of flour. After the flour is mixed with water and subjected to a suitable kneading, a dough is formed, the dough is washed with a suitable concentration of weak saline water to remove bran, starch and proteins dissolved in water or dilute salt, and the remaining material having a viscoelastic network structure is called gluten (gluten), which consists of glutenin and gliadin. The properties of gluten determine the rheological properties of the dough and thus the food processing quality of the wheat variety. In many studies, gluten strength is often used to describe the food processing quality of wheat, and wheat can be classified into strong gluten wheat, medium gluten wheat and weak gluten wheat according to the strength of gluten. The method for measuring and identifying the quality of wheat mainly comprises physicochemical detection (including using various special instruments and analysis methods) and food processing detection (including baking, cooking and the like). The main indexes for measuring the processing quality of the wheat flour comprise gluten content, sedimentation value, water absorption, forming time, stabilization time, resistance to elongation, stretching area, swelling index, various kneading and mixing instrument parameters and the like.
SDS-sedimentation value (SDS-SV) is a comprehensive index reflecting wheat gluten content and quality, and is deeply valued by wheat quality breeding workers. The principle is that a certain amount of wheat flour absorbs water to expand under the action of weak acid medium to form floccule and slowly precipitate, and the sedimentation speed and volume reflect the content and quality of gluten. The sedimentation volume in the specified standard time is the sedimentation value, and is taken as the unit of ml. The larger the measured value, the higher the gluten content, the higher the gluten strength, and the better the baking quality of the flour. The Swelling Index (SIG) of glutenin is an important index for wheat quality evaluation, and is in obvious positive correlation with the SDS-sedimentation value. SIG indirectly reflects the content and quality of glutenin based on the swelling capacity of glutenin at different swelling times. SIG measurement has the characteristics of rapidness, simplicity, convenience, small sample consumption and the like, and is often used for quality detection of early-generation materials in wheat quality breeding.
The Farinograph (Farinograph) is one of the most widely used wheat quality detection instruments, and can be used for quality detection and quality control of wheat grains or flour in the processes of wheat breeding, storage, flour processing, food production and the like. The flour quality instrument is used for kneading by adding a proper amount of water into quantitative wheat flour, and a coordinate graph of the change of stirring resistance along with time, namely a flour quality curve, is drawn by computer software. And calculating the quality characteristic parameters of the flour according to the water adding amount and the flour quality curve so as to evaluate the strength of the gluten of the flour. The main parameters measured by the flour quality meter are Water Absorption (WA), dough formation time (DT), dough Stability Time (ST), degree of weakness (DS), and Flour Quality Number (FQN). WA is affected by factors such as protein content and starch granule breakage rate in wheat flour, and the higher the protein content and starch granule breakage rate, the higher the water absorption rate. DT and ST reflect the stability and degree of dough resistance. The longer DT and ST of the dough, indicating greater gluten strength, generally better bake processing characteristics. DS represents the rate of dough breakdown during mixing, reflecting the strength of the gluten. The larger the DS, the weaker the gluten, the more rheological the dough, the less processable and the less good the baking quality. FQN is an important index reflecting rheological characteristics of dough, and has a close relation with gluten strength, the FQN of strong gluten flour is higher, and the FQN of weak gluten flour is lower.
The mixer (mixogrph) is an important instrument for measuring the quality of wheat processing by measuring the change in rheological properties during the stirring of the dough. In the continuous kneading process of the dough, the kneading instrument measures and records the kneading resistance of the dough and draws a kneading curve map to provide the optimal kneading time, stirring endurance, rheological characteristics of other dough, baking estimated water absorption value and other indexes of the dough. The kneading and mixing instrument has the advantages of high detection speed, small flour consumption, high correlation with baking characteristics and the like, and has good guiding function on wheat quality improvement, wheat quality chemical research and development of special flour and flour products. Among the parameters obtained by the kneading apparatus, the Middle Peak Time (MPT) is a very important parameter. Generally, it is considered that the MPT has high correlation with the kneading time of actual and experimental baking and is an important prediction index of bread quality. The midline peak height (MPV) is related to the extensibility of the dough and the toasted volume of the bread, the Midline Peak Width (MPW) is related to the stretch resistance of the dough, and the midline peak area (MPI) is significantly related to the maximum stretch resistance of the dough, the stretch area, and the toasted volume. The fade resistance value (RBD) is related to the kneading resistance of the dough, with the greater the RBD, the weaker the strength of the dough and the poorer the kneading resistance.

The experiment was repeated 3 times using a 50g dough bowl. The specific operation steps are as follows: (1) 50g of flour (14% wet basis, 50g) of each sample to be tested was weighed according to the moisture content of the flour and the data given by the instrument software. After the instrument is opened and zero calibration is carried out, flour is put into a dough kneading bowl of 50g of the flour quality instrument, and a dough kneading bowl cover is covered. (2) Starting the dough kneading device, stirring, kneading and mixing for 1min, rapidly adding water, and covering with a dough kneading pot cover. After dough kneading until the peak is formed, it is observed whether the peak of the curve is between 500 + -20 FU. (3) If the peak value is between 500 +/-20 FU, continuing kneading dough, continuing softening for 12min after the curve starts to obviously decrease, finishing the powder quality map, and performing data acquisition and comparative analysis.
The results of the powder quality testing are shown in Table 3, from which it can be seen that: the dough forming time, dough stabilizing time and flour quality index of TL1Dx2m1/2/3 in 2016 and 2017 are all significantly higher than that of the control KN199 and transgenic receptor kn2-The attenuation degree is obviously lower than that of KN99 and a transgenic receptor KN2-The water absorption did not change significantly.

4. Kneading and mixing instrument analysis
The dough peak time (MPT), peak height (MPV), peak width (MPW), peak area (MPI) and anti-fade value (RBD) of the 1Dx2m1/2/3 transgenic line were determined in 2016 and 2017, respectively, using a kneader according to the methods of documents "AACC 54-40A" and "Sun et al (2015) (Sun, J., Yang, W., Liu, D., ZHao, J., Luo, G., Li, X., Liu, Y., Guo, J., and Zhang, A. (2015)., Improvement on Mixograph test through water addition and parameter conversion.J.integer.Agr.14: 1715-1722.". The method comprises the following specific steps: a kneading bowl of 10g was used. The total kneading time of the standard kneading machine is 10min, and the weighing amount M of the flour is (10g × 86)/(100-W), wherein W is the water content of the sample. The data obtained were analyzed with MixSmart software (AEW Consulting, Lincoln, Nebraska, USA). The curve of the kneading and mixing instrument is automatically drawn by a computer, the parameters exceed 40, and the analysis usually adopts the middle line (Midline) parameters which are divided into 4 categories of belt height, bandwidth, area and slope. Each index of the kneading and mixing instrument spectrum reflects the rheological characteristics and quality of the wheat dough.
The results of measurement of the main parameters measured by the kneading machine are shown in Table 4. As can be seen from the table: in 2016 and 2017, the dough peak time and the dough peak area of TL1Dx2m1/2/3 are obviously higher than those of a control, the fading resistance value is obviously lower than that of the control, and the peak height and the peak width are reduced compared with those of the control, so that TL1Dx2m1/2/3 reduces the extensibility of the dough, improves the elasticity and the kneading resistance of the dough, and further shows that the 1Dx2m1/2/3 gene has the functions of improving the gluten strength and improving the baking quality of the flour.

Figure BDA0002314832020000121
The SDS-sedimentation value (SDS-SV) and the glutenin Swelling Index (SIG) are comprehensive indexes for evaluating the quality and quantity of wheat gluten, and are highly positively correlated with the gluten strength. The peak time (MPT) and the peak area (MPI) in the parameters of the kneading and mixing device, the forming time and the Stable Time (ST) in the parameters of the flour quality device, the flour quality index (FQN) are positively correlated with the gluten quality, and the anti-fading value (RBD) in the parameters of the kneading and mixing device and the weakening Degree (DS) in the parameters of the flour quality device are negatively correlated with the gluten quality.
The results of the above measurements are combined to show that the SDS, SIG, MPT, MPI and FQN of the transgenic line of the mutant gene 1Dx2m1/2/3 are obviously improved compared with the control, the dough forming time and the stability time are obviously prolonged compared with the control, and the RBD and DS are obviously reduced compared with the control, which shows that the 1Dx2m1/2/3 transgenic line has better gluten quality and dough rheological property, thereby proving that the mutant gene 1Dx2m1/2/3 can obviously improve the processing quality of wheat flour.
