In-silico identification and characterization of POS1-like genes in rice
Rice is a staple food crop providing energy for more than fifty percent of the world population. Considering the world population growth rate and declining of arable area of crops, increasing the yield is utmost requisite for the rice breeders. Yield is a quantitative trait influenced by many minor genes. Among the agronomic traits, the rice grain size is the most important factors for yield and quality. It is reported to be controlled by many genes which showed continuous variation. Therefore, identification and characterization of novel genes for grain size would be useful for enhancing the yield and grain quality. Here, a known gene POS1 from Tomatilo plant for fruit size encoding two AP2 domain were used to identify homologous gene(s) in rice genome through in-silico analysis. A total of 87 protein coding genes were identified in rice genome of which eight gene were found to be encoding double AP2 domains which would be useful to understand the role of grain size in rice. Using the full-length gene sequence of these eight genes, SSR markers were developed for genetic mapping and marker assisted breeding in rice breeding programme. There were quit variable number of exon and intron among the homolog genes indicating the diverse role of genes. In Silico analysis of the protein sequences revealed the non-membranous nature and might be played an important role in gene expression and regulation. Therefore, cloning and functional characterization of these genes would facilitates bridging the gap between gene identification and breeding application.
Reasoning Method of Rapid Design System for Rice and Wheat Cleaning Device Based on Petri Net Model
A rapid design system of cleaning device on rice-wheat combine harvester can improve the design efficiency and quality. As the core part of the system, the reasoning mechanism plays an important role in the system. A reasoning method based on Petri net model was proposed in the rapid design system of cleaning device for rice-wheat combine. Based on the rules and models, a reasoning mechanism to design cleaning devices was constructed to express the parameter transfer relationship by means of the CPN Tools which presents description of Petri net model. Combined the Petri net model with the design knowledge of cleaning device, the design parameters are calculated and transferred by CPN Tools in which the reasoning simulation machine run. According to the reasoning results, the parameterized model library of cleaning device is called to obtain the 3D models of cleaning device parts. The existing experimental verified intelligent design virtual simulation and experimental system are used to simulate the working process of cleaning device. The simulation result shows that the loss rate of the cleaning device is about 1.8 %, and the simulation impurity rate is about 0.9 %, which meets the technical requirements stipulated by the state.
Next-generation Bio-stimulants and Micronutrients Interventions Ameliorating Climate-induced Stress in Guava
Stress related to climate change or environment stress have began a major problem for production as well as quality enhancement for horticultural crops. Important stress related to climate changes are drought, water logging, soil salinity, heavy wind and temperature fluctuation. To tackle this problem a economic friendly and practically accepted methods need to be developed. Using new generation PGR’s and micronutrient is one of them. Among the PGR’s Salicylic acid @ 600 ppm was found to be most effective in various trait influencing abiotic stress like proline content, relative leaf water content, carotenoid content. Whereas most effective PGR for parameter like chlorophyll content A and chlorophyll content B was Brassinosteroid @ 1 ppm compared to control. With respect to micronutrients foliar feeding of zinc chloride @ 0.4% was fond to be most superior treatment among different micronutrients with respected to charcters like chlorophyll A content, chlorophyll B content and carotenoid content.
Comparative study of Biochemical attributes in Khasi Mandarin ( Citrus reticulata ) among different districts of Assam
Khasi Mandarin (Citrus reticulata Blanco) is a commercially popular and nutritionally rich subtropical citrus species in the North Eastern Himalayan region of India including Assam. In the present study during the analysis of the biochemical constituents of Mandarin juice among the seven different districts i.e. Tinsukia, Lakhimpur, Jorhat, Golaghat, Karbi Anglong, Dima Hasao and Kamrup with accession number “AKM”( Assam Khasi Mandarin) from 01 to 07 for districts respectively and T1 to T5 for plant number. The highest TSS of 11.9 0Brix was recorded in AKM07T2 and the lowest was recorded in AKM06T2 i.e. 6.22 0Brix. The highest pH of 5.98 was observed for AKM03T1 and the lowest (3.26) for AKM02T1. The titrable acidity of fruits recorded a mean of 0.66% was recorded for AKM02T1. Similarly, the lowest (0.32%) was recorded for AKM06T1. The TSS: Acid ratio for all the accessions recorded a mean of 13.82 within the range of 7.92-23.33. On the other hand, the total sugars for all the accession were within the range of 5.03- 5.98% with a mean of 5.43%. The highest ascorbic acid content (49.98) was recorded for AKM01T2 and the lowest of 24.99 was documented for AKM06T2. The total antioxidant activity of all the accessions were within the range of 0.08-0.24 with a mean of 0.16. The highest value for total flavonoid content was recorded for AKM05T1 (9.56) and the lowest for AKM04T1 (4.34).
Optimizing Rice Growth in NEH Region of India: Impact of Transplanting Time and Levels of Phosphorus
This study investigates the synergistic influence of transplanting time and varying levels of phosphorus on growth of rice crop. Planting dates of rice were carefully selected to represent key periods in cropping season in Ri-bhoi district of Meghalaya while the levels of phosphorus were carefully manipulated to assess the response of rice growth to these experimental treatments. Preliminary results indicated that rice crop transplanted on 3rd July produced significantly higher tiller number (14.18 hill-1), leaf area (1594.85 cm2) and accumulated dry matter (57 g hill-1) followed by 13th July transplanted crop. Rice crop transplanted on 2nd August produced least number of tillers (11.05 hill-1) resulting in reduced leaf area (1225.23 cm2) and lowest amount of accumulated dry matter (46.78 g hill-1). CGR was significantly affected by both transplanting dates and phosphorus levels. The highest CGR (6.21 g m-2 day-1) was observed in the crop transplanted on 3rd July. Net assimilation rate did not vary with change in transplanting dates of rice. However, phosphorus application significantly affected net assimilation rate. Maximum NAR was recorded from the crop receiving 90 kg P2O5 ha-1.
