Design of CRISPR/Cas9 system for editing OsNRAMP7 involved in metal transport in TBR225 rice variety
Rice (Oryza sativa L.) is one of the major food crops but is deficient in minerals such as Zn. In rice, there were eight genes belonging to the Natural resistance-associated macrophage protein (NRAMP) family, of which OsNRAMP1, OsNRAMP4, OsNRAMP5, OsNRAMP6, and OsNRAMP8 were reported to transport metals such as iron (Fe), zinc, mangan (Mn).

Due to the diversity of rice varieties and cropping systems in China, the limitation of seeding density and seedling quality makes it hard to improve machine-transplanted efficiency. Previous studies have shown that indica and japonica varieties varied in machine transplanting efficiency and optimal seeding density.

This study was conducted to provide data on the weed species composition of the Cyperaceae and Poaceae in the rice fields in An Giang province. The study results show that the weed species composition of Cyperaceae and Poaceae families is very diverse with 38 species belonging to 25 genera, of which 27 are usable. The largest number of species is in crop 1 and in the fields inside the ring dike.

The impact of Improved agricultural practice (IAP) with emphasis on soil analysis based organic manure and chemical fertilizer application, replacement of 25% chemical fertilizer with Bio-fertilizers and Integrated Pest Management, was studied for 3 successive years in 5 fields in Ricelentil – Okra cropping system in Gangetic Alluvial zones of West Bengal, India. IAP was seen to have significant beneficial effects on elevating soil organic carbon content and increase soil pH towards normality.

A study was conducted in an ongoing field experiment started during Rabi 1988-89 in calcareous soil at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar. The experimental design was split-plot with four fertilizer levels (0, 50, 100 & 150% NPK) in main plots and four levels of manures (no manures, compost @10 t ha-1 , crop residues and compost @10 t ha-1 plus crop residues) in sub-plots.

Rice is commonly grown by transplanting one month-old seedlings into puddled and continuously flooded soil which leads to higher losses of water through puddling, surface evaporation and percolation. Excessive pumping of water for puddling causes problems of declining water table and poor quality water for irrigation.

The DTPA extractable cationic micronutrients, sulphur and some important soil physico-chemical properties were investigated in two cropping system of Ramanathapuram district of Tamil Nadu using GPS technique. Considering the critical limits of soil micronutrients, all soil associations were not adequately supplied with DTPA extractable micronutrients in rainfed chillies and rice cropping systems.
