Hairy roots: An untapped potential for production of plant products
While plants are an abundant source of valuable natural products, it is often challenging to produce those products for commercial application. Often organic synthesis is too expensive for a viable commercial product and the biosynthetic pathways are often so complex that transferring them to a microorganism is not trivial or ...

Total Domination in Rooted Product Graphs [PDF]
During the last few decades, domination theory has been one of the most active areas of research within graph theory. Currently, there are more than 4400 published papers on domination and related parameters. In the case of total domination, there are over 580 published papers, and 50 of them concern the case of product graphs.

Italian Domination in Rooted Product Graphs [PDF]
In this article, we obtain closed formulae for the Italian domination number of rooted product graphs. As a particular case of the study, we derive the corresponding formulas for corona graphs, and we provide an alternative proof that the problem of computing the Italian domination number of a graph is NP-hard.

Deforestation of native tropical forests has occurred extensively over several decades. The plantation of fast-growing trees, such as Acacia spp., is expanding rapidly in tropical regions, which can contribute to conserve the remaining native tropical ...

MUTUAL EFFECT AMONG COMPOST AND FOLIAR SPRAYING WITH ZINC AND BORON ON SUGAR BEET (Beta vulgaris l.) GROWN ON SALINE SANDY LOAM SOIL [PDF]
Two field experiments were conducted at the village (7) in Gelbana, North Sinai Governorate, Egypt during two successive winter seasons of 2013/2014 and 2014/2015 to study the response of sugar beet (Mirodor) grown on saline sandy loam soil to study the ...

Root Architecture and Plant Productivity [PDF]
Water and nutrient availability limit plant growth in a11 but a very few natural ecosystems. They limit yield in most agricultural ecosystems, and in the United States and other industrialized nations, intensive irrigation and fertilization have generated serious environmental problems.

Products of Orthophosphate Absorption by Barley Roots [PDF]
The rate-limiting step of orthophosphate absorption by barley roots has been shown by kinetic studies (5) to be coupled to two of the sites of oxidative phosphorylation associated with isolated mitochondria. One of the reactions is coupled to reduced cytochrome b and the other to reduced diphosphopyridine nucleotide (DPNH).

Large-girth roots of graphs [PDF]
We study the problem of recognizing graph powers and computing roots of graphs. Our focus is on classes of graphs with no short cycles. We provide a polynomial time recognition algorithm for r-th powers of graphs of girth at least 2r vertical bar 3, thus

A plant’s health and productivity is influenced by its associated microbes. Although the common/core microbiome is often thought to be the most influential, significant numbers of rare or uncommon microbes (e.g., specialized endosymbionts) may also play ...
