Root Hairs [PDF]

open access: yesThe Arabidopsis Book, 2014
Roots hairs are cylindrical extensions of root epidermal cells that are important for acquisition of nutrients, microbe interactions, and plant anchorage. The molecular mechanisms involved in the specification, differentiation, and physiology of root hairs in Arabidopsis are reviewed here.

Chlorophyll, Proximate and Mineral Composition of Yam Leaves Grown under Aeroponics and Field Systems [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2020
The chlorophyll, proximate and mineral compositions of four elite yam varieties grown under aeroponic and field systems were investigated. The yam varieties used were TDa 98/01176, TDr 95/18544, TDr 95/19177 and TDr 95/19158.

Hairy Roots of Scutellaria spp. (Lamiaceae) as Promising Producers of Antiviral Flavones

open access: yesMolecules, 2021
We measured and studied the growth parameters and the qualitative and quantitative composition of the flavones of hairy roots of the Scutellaria genus: S. lateriflora, S. przewalskii and S. pycnoclada.

Maximal rank root subsystems of hyperbolic root systems

open access: yes, 2003
A Kac-Moody algebra is called hyperbolic if it corresponds to a generalized Cartan matrix of hyperbolic type. We study root subsystems of root systems of hyperbolic algebras.

One pot ‘click’ reactions: tandem enantioselective biocatalytic epoxide ring opening and [3+2] azide alkyne cycloaddition [PDF]

open access: yes, 2010
Halohydrin dehalogenase (HheC) can perform enantioselective azidolysis of aromatic epoxides to 1,2-azido alcohols which are subsequently ligated to alkynes producing chiral hydroxy triazoles in a one-pot procedure with excellent enantiomeric excess.

Root Vertex Valency Distributions of Rooted Maps and Rooted Triangulations

open access: yesEuropean Journal of Combinatorics, 1994
We obtain the asymptotic distributions of root vertex valencies for rooted maps and rooted triangulations on general surfaces. We show that the asymptotic distributions are independent of the surface.

The involvement of auxin in root architecture plasticity in Arabidopsis induced by heterogeneous phosphorus availability

open access: yesBiologia Plantarum, 2013
Homogeneous low phosphorus availability was reported to regulate root architecture in Arabidopsis via auxin, but the roles of auxin in root architecture plasticity to heterogeneous P availability remain unclear.

Effects of pruning on mineral nutrients and untargeted metabolites in fresh leaves of Camellia sinensis cv. Shuixian

open access: yesFrontiers in Plant Science, 2022
Pruning is an important strategy for increasing tea production. However, the effects of pruning on tea quality are not well understood. In this study, tea leaves were collected from Wuyi Mountain for both ionomic and metabolomic analyses. A total of 1962

Atenolol versus losartan in children and young adults with Marfan's syndrome [PDF]

open access: yes, 2014
BACKGROUND : Aortic-root dissection is the leading cause of death in Marfan's syndrome. Studies suggest that with regard to slowing aortic-root enlargement, losartan may be more effective than beta-blockers, the current standard therapy in most centers.
