Abstract:
Viral diseases are the important diseases next to the fungal and bacterial in Nepal. The increase in incidence and severity of viral diseases and emergence of new viral diseases causes the significant yield losses of different crops in Nepal. But the research and studies on plant viral diseases are limited. Most of the studies were focused in viral diseases of rice (Rice tungro virus and Rice dwarf virus), tomato (Yellow leaf curl virus) and potato (PVX and PVY). Maize leaf fleck virus and mosaic caused by Maize mosaic virus were recorded as minor disease of maize. Citrus Tristeza Virus is an

Abstract:
Rice black streaked dwarf virus (RBSDV) is an important agent causing maize rough dwarf disease, whereas the host factors responding to RBSDV infection are poorly understood. To uncover the molecular interactions between RBSDV and maize, a yeast two-hybrid screen of a maize cDNA library was carried out using the viral P8 protein as a bait. ZmAKINβγ-1 and ZmAKINβγ-2 (βγ subunit of Arabidopsis SNF1 kinase homolog in maize) possessing high sequence similarities (encoded by two gene copies) were identified as interaction partners. Their interactions with P8 were confirmed in both Nicotiana bentham

In Nepal, maize ranks second after rice both in area and production. In recent years, maize area and production has shown a steady increase, but productivity has been low (2.46 t/ha). The major maize producing regions in Nepal are mid hill (72.85%), terai (17.36%) and high hill (9.79%) respectively. A literature review was carried out to explore major maize diseases and their management in Nepal. The omnipresent incidence of diseases at the pre harvest stage has been an important bottleneck in increasing production. Till now, a total of 78 (75 fungal and 3 bacterial) species are pathogenic to

 Introduction: Maize (Zea mays) is one of the most important cereal crops. It is ranked as 3rd after wheat and rice. Due to its wide adaptability, diversified uses, and low production costs, it has great potential as a cereal crop. In the case of yield losses, various factors are involved. The fungal diseases of maize play a significant role in the reduction of both quantity as well as the quality of maize.

Mexico, more accurately Mesoamerica, is recognized as the origin of maize (including pigmented maize), with its first ancestor traced back to Tehuacán, Puebla, Mexico. Pigmented maize owes its vibrant colors due to its anthocyanin (i.e., cyanidin-3-glucoside) contents, which contribute to the red, purple, or blue coloration and offer notable health benefits.

Wheat is the most widely grown crop on earth, together with rice it is second to maize in total global tonnage. One of the emerging threats to wheat is stripe (yellow) rust, especially in North Africa, West and Central Asia and North America. The most efficient way to control plant diseases is to introduce disease resistant genes. However, the pathogens can overcome rapidly the effectiveness of these genes when they are wildly used. Therefore, there is a constant need to find new resistance genes to replace the non-effective genes. The resistance gene pool in the cultivated wheat is depleted a

Abstract:
This paper is a synthesis of findings from 11 value chains case studies in six countries across sub- Saharan Africa, carried out as part of the APRA programme during 2020–21. The countries and their respective value chains case studies included: Ethiopia (rice), Ghana (oil palm and cocoa), Malawi (groundnuts), Nigeria (maize, cocoa and rice), Tanzania (rice and sunflower) and Zimbabwe (tobacco and maize). A political economy analysis (PEA) framework was used to examine the performance of the selected value chains in the six countries. The starting point for the studies was that the success of

Abstract:
The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the

Full text
Abstract:
To assess climate change effects on crop yields, remote sensing-derived yield and agrometeorological reanalysis data are used to construct a panel at 0.1-degree resolution for 2003–2015. Regressions controlling for grid cell-specific intercepts and time trends, temperature, rainfall, and cloudiness estimate the subregional relationships between yields and precipitation-evapotranspiration extremes for rice, wheat, and maize. Results imply that climate change will cause global yield reductions for all crops, with losses highest for wheat and maize, especially in South Asia and Southern Africa.

Full text
Abstract:
Rice is Tanzania’s third most important staple crop after maize and cassava, and produced by more than 1 million households who are mostly small-scale farmers. Meanwhile sunflower is the most important edible oil crop in Tanzania, also grown mostly by small-scale farmers. Over the last two decades, rice and sunflower have increasingly become important sources of income. This can be attributed to efforts by the government, in collaboration with development agencies, to commercialise rice and sunflower production to improve livelihoods and reduce poverty among actors in both value chains.

Abstract:
Communities across the world have consumed foods from millet “ as a traditional food and source of nutrition “ for generations. However, with changes in lifestyle and dietary habits, millet has lost its prominence, making many countries dependent on import-driven cereals like rice, wheat, and maize. Despite the potential to address food and nutritional security, millet production has declined. Millet is a climate-resilient crop that have been identified as an alternative to potential cereals in the hilly regions of the Hindu Kush Himalayan region in addressing food and nutrition security, espe

Abstract:
Southern Madagascar’s worst drought in 40 years had devastating cumulative effects on harvest and livelihoods. On top of this, frequent sandstorms and pest infestations have led to severe stress on vegetation triggering a drastic decline in rice, maize and cassava production. These environmental aspects, combined with a lack of livelihood diversification and ongoing poverty, the presence of cattle raiders and restrictive government decisions, have driven the population of southern Madagascar to acute food insecurity conditions. By December 2021, more than 1.6 million people were estimated to h

Abstract:
The long-term goal of this research is to understand how pollen cope with stress, and identify genes that can be manipulated in crop plants to improve reproductive success during heat stress. The specific aims were to: 1) Compare heat stress dependent changes in gene expression between wild type pollen, and mutants in which pollen are heat sensitive (cngc16) or heat tolerant (apx2-1). 2) Compare cngc16 and apx2 mutants for differences in heat-stress triggered changes in ROS, cNMP, and Ca²⁺ transients. 3) Expand a mutant screen for pollen with increased or decreased thermo-tolerance.
