Abstract:
... Boron (B) is essential for growth and development, with the B requirement differing depending on the particular organs and tissues, but the molecular mechanisms underlying the preferential distribution of B to different tissues are poorly understood. We investigated the role of a rice gene (OsBOR1) encoding a B efflux transporter in the distribution of B to different tissues under different B supp ...

Abstract:
... Water spinach (Ipomoea aquatica Forssk.) is a popular semi-aquatic vegetable with high arsenic (As) accumulation capability in tropical and subtropical areas, and it can grow under both flooding and upland conditions. Because only few studies addressed the dietary As risk of vegetable consumption, this study investigated the accumulation and speciation of As in the water spinach, and the human hea ...

Abstract:
... Microbial pathogens attack every plant tissue, including leaves, roots, shoots, and flowers during all growth stages. Thus, they cause several diseases resulting in a plant's failure or loss of the whole crop in severe cases. To combat the pathogens attack, plants produce some biologically active toxic compounds known as saponins. The saponins are secondary metabolic compounds produced in healthy ...

Abstract:
... Sunlight filtered by green plant tissue becomes diminished in its ratio of red to far‐red wavelengths (R:FR). Some parasitic plants exploit this change by growing towards regions of low R:FR to locate host plants. In principle, variation in R:FR can also convey ecologically relevant information about host proximity or architecture. Here, we demonstrate that the parasitic vine Cuscuta epilinum Weih ...

Abstract:
... There are dilemmas in the minds of consumers with respect to sugar consumption – they would like to consume sugars for sweetness, but in a healthy (and perhaps guilt free!) way. In a sense, consumers believe that if sugar does not appear as an ingredient on the product label, but is intrinsic in the food (and will appear as a nutrient), it is ‘good’. As an ingredient, however, it is viewed as a ‘b ...

Abstract:
... Non‐structural carbon (NSC) storage (i.e. starch, soluble sugras and lipids) in tree stems play important roles in metabolism and growth. Their spatial distribution in wood may explain species‐specific differences in carbon storage dynamics, growth and survival. However, quantitative information on the spatial distribution of starch and lipids in wood is sparse due to methodological limitations. H ...
