Cassava postharvest physiological deterioration: a complex phenomenon involving calcium signaling, reactive oxygen species and programmed cell death.

Acta Physiol Plant 2017 3;39(4):91. Epub 2017 Mar 3.

Tropical Crops Genetic Resources Institute, Chinese Academy of Tropical Agricultural Sciences/Key Laboratory of Ministry of Agriculture for Germplasm Resources Conservation and Utilization of Cassava, Hainan, China.

Postharvest physiological deterioration (PPD) of cassava () storage roots is a complex physiological and biochemical process which involve many regulatory networks linked with specific proteins modulation and signaling transduction pathways. However, it is poorly understood regarding biological regulation, and the interactions among protein groups and signals to determine PPD syndrome in cassava storage roots. This review sheds some light on the possible molecular mechanisms involved in reactive oxygen species (ROS), calcium signaling transduction, and programmed cell death (PCD) in cassava PPD syndrome.

Compartment-specific investigations of antioxidants and hydrogen peroxide in leaves of during dark-induced senescence.

Acta Physiol Plant 2016;38:133. Epub 2016 May 6.

Center for Microscopy and Imaging, Baylor University, One Bear Place #97046, Waco, TX 76798 USA.

The aim of this study was to gain insight into the compartment-specific roles of ascorbate and glutathione in leaf senescence in . The subcellular distribution of ascorbate, glutathione, and hydrogen peroxide (HO) was analyzed by transmission electron microscopy and correlated with the activity of antioxidative enzymes in wildtype plants and the ascorbate- and glutathione-deficient mutants - and -, respectively. Both mutants showed earlier and stronger senescence than the wildtype indicating the importance of a functioning ascorbate and glutathione cycle in the induction and regulation of senescence.

Lupine embryo axes under salinity stress. II. Mitochondrial proteome response.

Acta Physiol Plant 2013;35(8):2383-2392. Epub 2013 Apr 3.

Department of Plant Physiology, Faculty of Biology, Adam Mickiewicz University, ul. Umultowska 89, 61-614 Poznań, Poland.

Germination is the first step of plant growth in plant life cycle. An embryonic radicle protruding the seed coat is the first part of plant which has direct contact with external environment including salt-affected soil. In embryo axes, mitochondria are the main energy producer. Read More

Rapid systemic up-regulation of genes after heat-wounding and electrical stimulation.

Acta Physiol Plant 1997 ;19(4):571-6

Botany Department, North Carolina State University, NC 27695-7612, USA.

When one leaf of a tomato plant is electrically-stimulated or heat-wounded, proteinase inhibitor genes are rapidly up-regulated in distant leaves. The identity of the systemic wound signal(s) is not yet known, but major candidates include hormones transmitted via the phloem or the xylem, the electrically-stimulated self-propagating electrical signal in the phloem (the action potential, AP), or the heat-wound-induced surge in hydraulic pressure in the xylem evoking a local change in membrane potential in adjacent living cells (the variation potential, VP). In order to discriminate between these signals we have adopted two approaches. Read More
