Climate change and ozone depletion have caused increased ultraviolet B (UVB; 280-315nm) radiation levels on earth, which has been predicted to cause decreased growth and yield of various crops, including rice, the most important staple food worldwide. UVB radiation sensitivity varies extensively in Asian rice (Oryza sativa L.) and African rice (Oryza glaberrima Steud. and Oryza barthii A. Chev.) cultivars, and the activity of cyclobutane pyrimidine dimer (CPD) photolyase that repairs UVB-induced CPD is an essential factor underlying UVB sensitivity in rice.

Worldwide feralization of crop species into agricultural weeds threatens global food security. Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. Despite increasing attention in recent years, a comprehensive understanding of the origins of weedy crop relatives and how a universal feralization process acts at the genomic and molecular level to allow the rapid adaptation to weediness are still yet to be explored.

Our main purpose was to evaluate the expression of plastic and evolved genes involved in ecological speciation in the noctuid moth Spodoptera frugiperda, the fall armyworm (FAW); and to demonstrate how host plants might influence lineage differentiation in this polyphagous insect. FAW is an important pest of several crops worldwide, and it is differentiated into host plant-related strains, corn (CS) and rice strains (RS).

Sheath blight (SB), caused by Rhizoctonia solani, is a common rice disease worldwide. Currently, rice cultivars with robust resistance to R. solani are still lacking. To provide theoretic basis for molecular breeding of R. solani-resistant rice cultivars, the changes of transcriptome profiles in response to R. solani infection were compared between a moderate resistant cultivar (Yanhui-888, YH) and a susceptible cultivar (Jingang-30, JG).

The fall armyworm (Spodoptera frugiperda (J.E. Smith)) is a highly polyphagous agricultural pest with long-distance migratory behavior threatening food security worldwide. This pest has a host range of > 80 plant species, but two host strains are recognized based on their association with corn (C-strain) or rice and smaller grasses (R-strain).

Rice leaf blight, which is a devastating disease worldwide, is caused by the bacterium Xanthomonas oryzae pv. oryzae (Xoo). The upregulated by transcription activator-like 1 (UPT) effector box in the promoter region of the rice Xa13 gene plays a key role in Xoo pathogenicity.

Bacterial blight, which is caused by Xanthomonas oryzae pv. oryzae (Xoo), is a devastating rice disease worldwide. Rice introgression line H471, derived from the recurrent parent Huang-Hua-Zhan (HHZ) and the donor parent PSBRC28, exhibits broad-spectrum resistance to Xoo, including to the highly virulent Xoo strain PXO99A , whereas its parents are susceptible to PXO99A .

Maize is considered to be the third most important cereal after rice and wheat in India. It is being cultivated worldwide in a wider range of environmental conditions, because of its greater adaptability. It is known to be affected by more than 62 diseases. Among them, turcicum leaf blight caused by Exserohilum turcicum (Pass.) Leonard and Suggs is of significant importance as it drastically reduces the yield by reducing photosynthetic activity of the plant.

Bacterial leaf blight of rice, caused by Xanthomonas oryzae pv. oryzae is not only a problem in India but also worldwide. Management using chemicals is undoubtedly quick in action, restricting the severity and spread of the disease. Both in vitro and in vivo studies were conducted to investigate the inhibitory potential of different chemicals against the bacterial pathogen.

Rice (Oryza sativa) is the most important staple food crop in India. It ranks second in worldwide production. An anatomical and physiological character of surface of the rice leaf renders a sustainable environment for diversity of phylloplane microorganisms that showed antagonism against rice pathogens. The objective of this present study was to identify and characterize the bacterial population in the phylloplane of rice at different critical stages.

Rice is an important food crop extensively grown in India. Several factors are responsible for reducing the rice productivity in worldwide. However, weed infestation is the major biotic threat to productivity of transplanted rice. Weeds are competed with rice by their high adaptability and faster growth, dominate the crop habitat and reduce the yield potential of rice. Weed management is an important agro-technique for successful transplanted rice cultivation. It can be achieved, either manual or mechanical or chemical weed control methods.

Excessive application of chemical fertilizers to attain higher yield has not only reduced the nutrient use efficiency but has also adversely affected the soil productivity and environmental stability. For this reason, immediate conversion to organic farming would drastically reduce production at initial phases which is of major concern to feed the growing population. This article is written with prime focus to notify on the yield variability under different integrated nutrient management approaches from research conducted worldwide.

Agriculture is going through a profound revolution worldwide due to increasing world demand for food, higher costs of energy and other inputs, environmental pollution problems, and instability of cropping systems. The importance of plant functioning can be realized from the facts that knowledge of mineral nutrition of plants has opened new vistas for fertilizer practices. The detection of deficiencies and toxicity of particular mineral nutrient element has enabled us to make adequate soil amendments and root nutrient absorption for better plant growth.

Rice (Oryza sativa L.) is one of the most important staple food crops worldwide. Nitrogen (N) is the most important nutrient in irrigated rice cultivation. Current high yields of irrigated rice are often associated with applications of higher doses of fertilizer N, as nearly 30-40 percent of applied nitrogen is actually utilized by the crop; even with the best agronomic practices. It has always been a problem to raise the utilization rate of the rice plant and to increase efficiency of absorbed nitrogen for grain production.

Variability in climate regimes of rainfall and temperature is a source of biotic and abiotic stresses in agricultural systems worldwide. This study examines seasonal and annual rainfall and temperature variability in rice, wheat and jute crop productivity for five decades (1972–2012) under long-term fertilizer experiment in alluvial soils of eastern India. The climatic variations and impacts were captured using a standardized precipitation index (SPI), diurnal temperature range (DTR) and crop productivity index (CPI).

The development of genome-wide association studies (GWAS) in crops has made it possible to mine interesting alleles hidden in gene bank resources. However, only a small fraction of the rice genetic diversity of any given country has been exploited in the studies with worldwide sampling conducted to date.

Rice blast disease is one of the most serious and recurrent problems in rice-growing regions worldwide. Most resistance genes were identified by linkage mapping using genetic populations. We extensively examined 16 rice blast strains and a further genome-wide association study based on genotyping 0.8 million single nucleotide polymorphism variants across 366 diverse indica accessions.
