The disruption of the succinic semialdehyde dehydrogenase (SSADH) function in Arabidopsis leads to aberrant growth phenotype. In human, the SSADH malfunction leads to a condition known as γ-hydroxybutyrate (GHB) aciduria. It is characterized by the accumulation of GHB as well as abnormal growth. GHB aciduria is treated pharmacologically with compounds analogous to gamma-aminubutyrate (GABA). One of these compounds... Read more.

The genotype by environment interaction (GEI) reduces the success of genotype selection and recommendations by breeders, thus slowing down the progress of plant breeding. The understanding of genotype by environment interaction (GEI) multi-locational yield trials (MLYT) enables researchers to identify locations which are efficient in distinguishing tested genotypes, which are ideal across the test-locations as well as...

The artificial lighting conditions which promoted growth of the gametophytes and sporophytes of brown alga Undaria pinnatifida were examined. The seaweed was subjected to continuous or intermittent white, blue, or red light. There were notable, but not significant, differences in gametophyte and sporophyte growth between continuous and intermittent (104 Hz) white light conditions. Gametophyte growth was promoted most...

Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated pulse crops in most developing countries. However, its cultivation is globally constrained mainly by low soil fertility and lack of improved agronomic practices. A field experiment was conducted at Hawassa University College of Agriculture, Hawassa Southern Ethiopia to determine the effect of N fertilization and Rhizobium phaseoli... Read more.

Dalbergia sissoo (shisham) seeds naturally infected with Curvularia lunata showed either black discoloration (1.25 to 8.75%) or appeared dull (0.50 to 10.0%). When they were incubated, they yielded pure growth of the pathogen. During location studies, cleared whole mount preparation and component plating revealed the presence of infection restricted to the seed coat and cotyledons of asymptomatic... Read more.

This study was carried out within February to June, 2015 to 2016 on macrofungi samples collected from different localities within Iraqi Kurdistan region - Northern Iraq. This mountainous region is rich in forest trees with diverse groups of shrubs and herbs and is expected to support the growth of many macrofungal species. However, this part of Iraq is still unexplored from macrofungal point of view. In this paper seven... Read more.

Fruit and vegetable maturity at harvest influences transportation and storage requirements as well as market value. However, small scale farmers in Uganda lack technologies for maturity assessment leading to high pre- and post-harvest losses and low financial returns from fruit and vegetable farms. This study, therefore, assessed the development of fruits (pineapple, passion fruit, watermelon) and vegetables (cabbage,... Read more.

Salt stress is one of the major problems in agricultural fields. Currently, more than 20% of irrigated agricultural lands are affected by salinity. High concentrations of sodium affects plant growth by competing with the uptake of important ions like potassium (K+), and posing osmotic stress. Some plant species developed mechanisms such as modifying cellular metabolism to minimize effects of high salt concentrations.... Read more.
