Parthenolide: from plant shoots to cancer roots

Drug Discovery Today, 2013
Parthenolide (PTL), a sesquiterpene lactone (SL) originally purified from the shoots of feverfew (Tanacetum parthenium), has shown potent anticancer and anti-inflammatory activities. It is currently being tested in cancer clinical trials. Structure-activity relationship (SAR) studies of parthenolide revealed key chemical properties required for ...

Functional domains in plant shoot meristems

BioEssays, 2001
The development of higher plants depends on the activity of a shoot apical meristem. Organs are formed on the flanks of the meristem, while pluripotent stem cells are found in a separate domain in the meristem centre. Further domains are distinguished by the expression patterns of genes that control the development of the shoot meristem.

Overview of Plant Shooting Branch

Journal of Northeast Agricultural University (English Edition), 2012
Abstract The development of plant branching plays a pivotal role in the morphogenesis of plants. It is affected by the genes and also by the environment. Recent studies of plant branching had made great progresses in the development of the branch control of the physiology, biochemistry, functional genomics, comparative genomics and other aspects ...

High-Throughput Phenotyping of Plant Shoots

2012
Advances in automated plant handling and image acquisition now make it possible to use digital imaging for the high-throughput phenotyping of plants. Various traits can be extracted from individual images. However, the potential of this technology lies in the acquisition of time series.

Function of plant shoot meristems

Seminars in Cell & Developmental Biology, 2001
Growth and development of higher plants is directed by the continuous activity of meristems, sites of sustained cell division. Organs are formed at the flanks of the shoot meristem, while the central region contains pluripotent stem cells. The developmental programme of the meristem is coordinated by interactions between cells in separate regions of ...

Patterning and Polarity in Seed Plant Shoots

Annual Review of Plant Biology, 2008
Leaves and stems are ultimately derived from the shoot apical meristem (SAM); leaves arise from the peripheral zone of the SAM and stem tissue is derived from both the peripheral and central zones of the SAM. Both the peripheral and central regions of the SAM are formed during embryogenesis when the basic body plan of the plant is established ...

Regeneration of cassava plants via shoot organogenesis

Plant Cell Reports, 1998
A novel regeneration system based on direct shoot organogenesis is described for cassava. Plants could be regenerated at high frequency by inducing shoot primordia on explants derived from cotyledons of cassava somatic embryos. After a passage on elongation medium, the regenerated shoots were easily rooted in hormone-free medium and could be ...

Recovery of transgenic plants from “escape” shoots

Plant Cell Reports, 1989
The problem of escapes is well known to those investigating the regeneration of transgenic shoots from transformed callus. Shoots can pass various tests and assays for transformation, and are then scored as transgenic, but the progeny do not express the transferred trait and do not contain the T-DNA.

Shoot-Root Communication in Flowering Plants.

2023
As sessile organisms, terrestrial plants have evolved sophisticated mechanisms to coordinate the growth and development of two distinct systems, the shoot and the root, in response to environmental fluctuations. Adaptive systemic responses are accomplished by shoot-root communication, which involves diverse long-distance signalling molecules.
