Index. décimale : 575 Résumé : The jelly-like locular (gel) tissue of tomato fruit is made up of large thin-walled and highly vacuolized cells. The development of the gel tissue is characterized by the arrest of mitotic activities, the inhibition of cyclin-dependent kinase A (CDKA) activity, and numerous rounds of nuclear DNA endoreduplication. To decipher the molecular determinants controlling these developmental events, we investigated the putative involvement of CDK inhibitors (p27 Kip -related proteins, or KRPs) during the endoreduplication process. Two cDNAs, LeKRP1 and LeKRP2, encoding tomato CDK inhibitors were isolated. The LeKRP1 and LeKRP2 transcript expression was shown to be enhanced in the differentiating cells of the gel undergoing endoreduplication. At the translational level,LeKRP1 was shown to accumulate in the gel tissue and to participate in the inhibition of the CDK-cyclin kinase activities occurring in endoreduplicating cells of the gel tissue. We here propose that LeKRP1 participates in the control of both the cell cycle and the endoreduplication cycle En ligne : https://hal.inrae.fr/hal-02661083v1 Format de la ressource électronique : PDF Cyclin-dependent kinase (CDK) inhibitors regulate the CDK-cyclin complex activities in endoreduplicating cells of developing tomato fruit [document électronique] / Badia Bisbis, Auteur ; Frédéric Delmas, Auteur ; Jerome Joubes, Auteur . - The American Society for Biochemistry and Molecular Biology, 2006 . - 281 (11).

Device for measuring the plant physiology and electrophysiology / Serge Kernbach    

Public ISBD Faire une suggestion d'achat Titre : Device for measuring the plant physiology and electrophysiology Type de document : document électronique Auteurs : Serge Kernbach, Auteur Editeur : arXiv Langues : Anglais (eng) Catégories : 575 Anatomie et physiologie végétales Tags : 'measuring physiological  electrophysiological  plants  physiologie  spectroscopy  plantes  bio-physiological'. Index. décimale : 575 Résumé : This paper briefly describes the device - the phytosensor - for measuring physiological and electrophysiological parameters of plants. This system is developed as a bio-physiological sensor in precise agriculture, as a tool in plant research and environmental biology, and for plant enthusiasts in smart home or entertainment applications. The phytosentor measures main physiological parameters such as the leaf transpiration rate, sap flow, tissue conductivity and frequency response, biopotentials (action potentials and variation potentials), and can conduct electrochemical impedance spectroscopy with organic tissues. Soil moisture and temperature, air quality (CO2, NO2, O3 and other sensors on I2C bus), and general environmental parameters (light, temperature, humidity, air pressure, electromagnetic and magnetic fields) are also recorded in real time. In addition to phytosensing, the device can also perform phytoactuation, i.e. execute electrical or light stimulation of plants, control irrigation and lighting modes, conduct fully autonomous experiments with complex feedback-based and adaptive scenarios in robotic or biohybrid systems. This article represents the revised and extended version of original paper and includes some descriptions and images from the FloraRobotica and BioHybrids projects.
