“…The SSA of the same leaf rank increases with an increase in the N (nitrogen) rate. The maximum SSA increases with the leaf rank from the first to the third leaf, and then decreases from the third to the final leaf [12]. The canopy light and nitrogen distribution are related to the grain yield and nitrogen use efficiency in rice [13].…”

In the middle and lower reaches of the Yangtze River, the rainfall is greater in summer. The technology of rain catching and controlled irrigation of rice help to save water by raising the water depth of the field after rain while the soil water content during the rest period is maintained at 70–100% of field capacity. The objectives of this study were to evaluate rice growth, canopy light utilization, and yield of rice under different rain-catching and controlled irrigation modes (T1: light drought and low storage, T2: light drought and high storage), and to find the optimal storage depth after rain for rice. Measurements included the rice plant height, tiller number, high tiller growth, leaf angle, canopy interception rate, and yield shape. The plot experiment was conducted in 2012 and 2013 using Nanjing 44 (Oryza sativa L.) as the test material. The results showed that T1 treatment improved the height of rice plants and the number of effective tillers in the late growth stage. The number of high tillers had a great influence on the total leaf dry quality; compared with conventional irrigation (CK), the number of high tillers increased by 11.36% and 7.87% in T1 and T2, respectively; the canopy interception rate of T1 above 0 cm was higher than that in T2 and CK; and the leaf area index (LAI) was closely related to the 0–40 cm of canopy light distribution. The number of grains per panicle in T1 was lower than in CK and T2; however, the number of grains in T1 was less, and the 1000 grain weight was higher. On the 63 days and 83 days after transplanting in 2012 and 78 days after transplanting in 2013, the first, second, and third leaf angles of T1 were larger. Rain-catching and controlled irrigation can increase the dry weight and shoot dry weight of rice, and light drought and low storage (T1) conditions are good for maintaining a high yield because of more tiller number, more grains per panicle and reasonable light distribution.

“…To enhance our understanding of plant phenotypes that result from the interaction between G and E, high‐throughput phenotyping has started to be used in plant breeding and physiological studies to capture high‐resolution dynamic phenotypic data (Campbell et al, 2015; Furbank & Tester, 2011; Ge et al, 2019; Yendrek et al, 2017). Visible light/red, green, blue (RGB) cameras are often deployed to estimate plant morphological traits such as biomass, plant height, leaf area, and leaf angle (Ge, Bai, Stoerger, & Schnable, 2016; Zhang et al, 2017). Hyperspectral sensors capturing electromagnetic energy reflected from plant tissues are useful for detecting subtle physiological and chemical changes inside plants.…”

Much effort has been placed on developing microbial inoculants to replace or supplement fertilizers to improve crop productivity and environmental sustainability. However, many studies ignore the dynamics of plant-microbe interactions and the genotypic specificity of the host plant on the outcome of microbial inoculation. Thus, it is important to study temporal plant responses to inoculation in multiple genotypes within a single species. With the implementation of high-throughput phenotyping, the dynamics of biomass and nitrogen (N) accumulation of four sorghum genotypes with contrasting N-use efficiency were monitored upon the inoculation with synthetic microbial communities (SynComs) under high and low-N. Five SynComs comprising bacteria isolated from field grown sorghum were designed based on the overall phylar composition of bacteria and the enriched host compartment determined from a field-based culture independent study of the sorghum microbiome. We demonstrated that the growth response of sorghum to SynCom inoculation is genotype-specific and dependent on plant N status. The sorghum genotypes that were N-use inefficient were more susceptible to the colonization from a diverse set of inoculated bacteria as compared to the N-use efficient lines especially under low-N. By integrating high-throughput phenotyping with sequencing data, our findings highlight the roles of host genotype and plant nutritional status in determining colonization by bacterial synthetic communities.

Optimization of Western Blot Technique for Protein Expression of Rice Plant (Oryza sativa L.) Western blot (WB) technique has been widely used for analyzing protein expression and for identifying specific proteins derived from animals, plants, and microorganisms. During the use of WB, especially in agricultural studies, some difficulties are encountered such as unclear or unspecific protein bands, the presence of bubbles, and the absence of protein bands on membrane. This study aims to determine the WB conditions appropriate for the protein expression of rice plants (Oryza sativa L.). Protein from rice plant was extracted and the obtained protein lysate was then used for proteomic analysis using western blot with β-actin antibody. Our experiment showed that some optimized parameters like blocking buffers, the concentration of primary antibody and the ratio of secondary antibody determined the clarity of the results. β-actin was used as internal control that measured the success of the WB technique. Results showed that lysis process was important in determining good WB results in addition to the optimal blocking solution using a BSA of 0.2%, a primary antibody concentration of 1 μg mL–1, and a secondary antibody of 1:10,000. Optimizing techniques during extraction, incubation, and documentation facilitated good WB results.Keywords: β-actin; optimization; protein; rice plant; western blotABSTRAKTeknik western blot (WB) telah banyak digunakan untuk analisis ekspresi protein dan mengidentifikasi protein spesifik dari hewan, tumbuhan dan mikroorganisme. Dalam implementasi teknik WB, khususnya studi dalam bidang pertanian, beberapa kesulitan ditemui seperti pita protein tidak jelas, tidak spesifik, adanya gelembung, hingga tidak munculnya pita protein pada membran. Penelitian ini bertujuan untuk mengetahui kondisi WB yang tepat untuk deteksi protein tanaman padi (Oryza sativa L.). Protein tanaman padi diekstraksi, kemudian lysate protein yang didapat dianalisis dengan metode westernblot menggunakan antibody β-actin. Penelitian kami menunjukkan bahwa beberapa parameter yang dioptimasi seperti larutan blocking, konsentrasi antibodi primer dan rasio antibodi sekunder akan menentukan hasil yang jelas. β-actin digunakan sebagai kontrol internal yang menjadi tolok ukur keberhasilan teknik WB. Hasil menunjukkan bahwa proses lisis menjadi hal penting dalam menentukan hasil WB yang baik disamping larutan blocking yang optimal menggunakan BSA 0,2%, konsentrasi antibodi primer 1 µg mL–1 dan antibodi sekunder 1:10.000. Mengoptimalkan teknik selama ekstraksi, inkubasi dan dokumentasi membantu mendapatkan hasil WB yang baik.
