Endogenous oscillations of electric potential difference in the cambial region of the pine stem. I. General characteristics of the oscillations

open access: yesActa Societatis Botanicorum Poloniae, 2014
Extracellular measurements of electric potential difference (PD) in isolated tissue blocks from Scots pine were performed. Endogenous transient PD changes (oscillations) generated exclusively in the cambial region were found.

A Phloem-Expressed PECTATE LYASE-LIKE Gene Promotes Cambium and Xylem Development

open access: yesFrontiers in Plant Science, 2022
The plant vasculature plays essential roles in the transport of water and nutrients and is composed of xylem and phloem, both of which originate from undifferentiated cells found in the cambium.

Is interlocked grain an adaptive trait for tropical tree species in rainforest? [PDF]

open access: yes, 2009
Many trees in tropical rain forest exhibit interlocked grain. This phenomenon was observed, using a splitting method, on 10 trees from different genera in French Guiana. There were rather strong variations between and within trees. Different indexes were

Single Cell Multiomics of Hooked Potato Stolons Reveals Parallels to Shoot Apical Meristems in Arabidopsis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Solanum tuberosum L. (potato) is a key food crop, with its tubers serving as an important food source worldwide. Tuber development is a tightly regulated process involving the transition of a hooked stolon (a modified stem) to a tuber following the perception of mobile signals within the stolon tip. While genes like FLOWERING LOCUS T homologue

Morpho-histological analysis of tomato (Solanum lycopersicum L.) plants after treatment with juglone

open access: yesActa Agrobotanica, 2017
Juglone is a substance that limits plant growth and has a toxic effect on plant development. In this study, we analyzed the influence of juglone at two different concentrations (10−3 M and 10−4 M), which were applied to different parts of Solanum ...

Comparison of Cold Hardiness Evaluation of Woody Species by ELLT and TTCLT

open access: yesHortScience, 2020
Cold hardiness evaluation is important for screening woody species in cold areas. We compared cold hardiness by estimating the 50% lethal temperature (LT50) using electrolyte leakage test (ELLT50) and triphenyltetrazolium chloride test (TTCLT50) for 26 ...

Living on borrowed time – Amazonian trees use decade‐old storage carbon to survive for months after complete stem girdling [PDF]

open access: yes, 2018
Nonstructural carbon (NSC) reserves act as buffers to sustain tree activity during periods when carbon (C) assimilation does not meet C demand, but little is known about their age and accessibility; we designed a controlled girdling experiment in the ...
