Phylogenetic rooting experiments demonstrate that two chloroplast genes from commelinoid monocot taxa that represent the closest living relatives of the pickerelweed family, Pontederiaceae, retain measurable signals regarding the position of that family's root. The rooting preferences of the chloroplast sequences were compared with those for artificial sequences that correspond to outgroups so ...

BACKGROUND AND AIMS The evolution of complex rooting systems during the Devonian had significant impacts on global terrestrial ecosystems and the evolution of plant body plans. However, detailed understanding of the pathways of root evolution and the architecture of early rooting systems is currently lacking. We describe the architecture and resolve the structural homology of the rooting system...

In a recent paper [1] Bernard, Golterman, Shamir, and Sharpe challenge the proof developed in [2–4] showing that nonperturbative effects are incorrectly treated in the rooting formalism popular for reducing the number of fermion species in the staggered formalism for dynamical quarks. Here I discuss how this challenge is based on a misunderstanding of the chiral behavior of staggered quarks. Th...

Number of days from transplanting to rooting varies depending on the weather conditions, which has not been considered in developmental prediction but must affect the accuracy. A method to estimate the rooting day when calculation should be started was proposed using within-the-season growth data of the particular field.

Shoot tip cuttings of Quercus phillyraeoides A. Gray ‘Emerald Sentinel’ (‘Emerald Sentinel’ oak), in a transitional growth stage between softwood and semi-hardwood, were collected from containerized plants growing under uniform fertility on June 4, 1998. Cuttings were treated with talc formulations of indolebutyric acid (IBA), ranging from 0 to 8000 ppm (0.8%), and placed under intermittent mis...

چکیده این تحقیق در بخشی از سامان عرفی شوراب چنار بگالی استان لرستان که بلوط ایرانی (quercus brantii lindl.) گونه غالب جنگل های آن است صورت پذیرفت. در مطالعه ی حاضر به منظور بررسی تاثیر عوامل توپوگرافی (ارتفاع از سطح دریا، شیب و جهت زمین) بر فاکتورهای تاج پوشش، مساحت تقریبی 1500 هکتار انتخاب گردید. سپس تعداد 147 قطعه نمونه مستطیلی به ابعاد 20 ×10 متر با استفاده از شبکه آماربرداری منظم - تصادفی ...

studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as henna. the purpose of this study is to determine an appropriate concentration of naphthalene acetic acid (naa), indole butyric acid (iba) and salicylic acid (sa) on rooting of henna. present study showed that there was a great variation in most of the measured characters at p<...

In 1993, we published a paper in Development detailing the anatomical structure of the Arabidopsis root. The paper described how root growth was maintained by the precisely tuned activity of a small set of 'initials', which acted as the source of dividing and differentiating cells, and how these stem cell-like cells surrounded a few infrequently dividing cells. This work underpinned subsequent ...

The micropropagation of Stevia rebaudiana using stem node segment explants obtained from 2 years-old shrubs were achieved. Cultures were established on Murashige and Skoog (MS) as the medium supplemented with different concentrations of 6-benzylaminopurine (BA) at concentration, 0.0, 0.1 and 0.5 mg/l individually or in combination with Kinetin (Kin) at concentration, 0.0, 0.1 and 0.5 mg/l. The ...
