Gene expression is under the control of transcription factorsand various epigenomic modifications of the chromatin such asthe methylation patterns of the genomic DNA (gDNA) and variouschemical changes of histone proteins. Small RNAs are anotherimportant regulator of plant chromatin structure and geneexpression [1,2].

Switchgrass (Panicum virgatum L.) is a C4-grass with deep fibrous root systemsindigenous to North America. In recent years switchgrass has been considered to bea “model” energy crop due to its high productivity, perenniality, and adaptability tovarious sites and soils. This paper specifically reviews published works on the effect ofcultural management practices on switchgrass establishment, bi ...

Wheat supplies about 20% of the total food calories consumedworldwide, feeds approximately half of the global demand fordietary proteins, and is a national staple in many countries [1]. Inthe United States, the per capita consumption of wheat exceedsthat of any other single food grain. Besides being a major sourceof energy and nutrition it is also a major cause of frequent dietinducedhealth is ...

The leaf lamina (blade) is a highly organized photosyntheticstructure in which cells in the upper (adaxial) and lower (abaxial)surfaces are morphologically different associated with differentfunctional specializations. The adaxial palisade mesophyll cellsare specialized for solar energy capture and the abaxial spongymesophyll cells are specialized for gas exchange, while thevascular bundles in ...

It is now widely accepted that chromatin is a highly dynamic structure thatparticipates in all DNA-related functions, including transcription, DNA replication, repair,and programmed cell death. Chromatin compaction influences plant regeneration anddevelopment. In plants, the most popular method of detecting chromatin compactionis immunofluorescence coupled with confocal microscopy. This method ...

Origin, Distribution and Heading date in Cultivated Rice

Mahmoud Dogara, Abdulrahman et al. [2014]

Rice is one of the most important global food crops and a primary source ofcalories for more than half of the world’s population. There are two cultivated andtwenty-one wild species of genus Oryza. O. sativa, the Asian cultivated rice is grownall over the world. The African cultivated rice, O. glaberrima is grown on a small scalein West Africa. The genus Oryza probably originated about 130 mil ...

Divergence analysis of 60 genotypes for ten biometrical traits was carried outusing Mahalanobis D2 statistic. The genotypes were grouped into ten clusters. Thecluster I was the largest with 30 genotypes followed by cluster II with 15 genotypes,cluster III with seven genotypes, cluster IX with two genotypes and clusters IV, V, VI, VII,VIII and X had accommodated only single genotype each. The i ...

This study investigates the phytofungicidal potentials of aqueous extracts ofMangifera indica and Jatropha curcas on the Fusarium pathogens of millet seedlings insouthwestern Nigeria. Aqueous extracts of M. indica and J. curcas prepared at 0.15,0.30 and 0.45 mg/ml concentration levels were evaluated in-vitro using standardmethods, while the in-vivo experiment was carried out using soil inocula ...

Cotton plant is susceptible to different pests and deceases and is necessarily treatedwith pesticides. Insecticides are used most of all pesticides in agriculture worldwide.These chemicals are efficiently used; however they often cause the plant to be moresusceptible to pests and deceases. The reason of this phenomenon is explained withthe fact that defensive compounds in plant tissues lower. ...

Yellow starthistle is an invasive plant species that reduces productivity and plantdiversity within the canyon grasslands of Idaho. Early detection of yellow starthistleand predicting its spread has important managerial implications that could greatlyreduce the economic/environmental losses due to this weed. The spread of an invasiveplant species depends on its ability to reproduce and dispers ...
