CELL PRODUCTION BY ROOT CAPS [PDF]
New Phytologist, 1976 SUMMARYFour independent methods show that the cell‐doubling time of the first tier of cap initials is about 10 h in roots of Zea growing at 23°C. By the fourth tier the cell‐doubling time lengthens to about 90 h due to cells going out of cycle though these can go on synthesizing DNA. The first four tiers produce enough cells to renew the cap in from 22

Alfalfa Root Flavonoid Production Is Nitrogen Regulated [PDF]
Plant Physiology, 1995 Flavonoids produced by legume roots are signal molecules acting both as chemoattractants and nod gene inducers for the symbiotic Rhizobium partner. Combined nitrogen inhibits the establishment of the symbiosis. To know whether nitrogen nutrition could act at the level of signal production, we have studied the expression of flavonoid biosynthetic genes ...

Hairy roots: An untapped potential for production of plant products
Frontiers in Plant Science, 2022 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 feasible.

On the metric dimension and fractional metric dimension for hierarchical product of graphs
, 2012 A set of vertices $W$ {\em resolves} a graph $G$ if every vertex of $G$ is uniquely determined by its vector of distances to the vertices in $W$. The {\em metric dimension} for $G$, denoted by $\dim(G)$, is the minimum cardinality of a resolving set of ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Use of plant growth regulators in fig tree seedlings ‘Roxo de Valinhos’
Bioscience Journal, 2018 The application of plant growth regulators can promote better development of the seedlings, essential for the success of fruit growing. The current study aims to evaluate the use of plant growth regulators in fig tree seedlings ‘Roxo de Valinhos’.

Broken bodies and present ghosts: Ubuntu and African women’s theology
HTS Teologiese Studies/Theological Studies, 2017 In this article, the notion of broken bodies is explored in relation to the African body and the history of colonialism in South Africa. This exploration will be rooted in a retelling of the story of the woman, Saartjie Baartman.

Products of Orthophosphate Absorption by Barley Roots [PDF]
Plant Physiology, 1960 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).

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
