Abstract
Mediterranean tomato landraces adapted to arid environments represent an option to counteract drought, and to address the complexity of responses to water deficit and recovery, which is a crucial component of plant adaptation mechanisms. We investigated physiological, biochemical and molecular responses of two Mediterranean tomato landraces, 'Locale di Salina' (Lc) and 'Pizzutello di Sciacca' (Pz) under two dehydration periods and intermediate rehydration in greenhouse pot experiments. Relationship between CO2 assimilation (A) and stomatal conductance under severe water stress (gs < 0.05 mol·m-2 ·s-1 ) indicated the occurrence of stomatal and non-stomatal limitations of photosynthesis. Gas exchange promptly recovered within 2-3 days of rehydration. ABA and gs showed a strict exponential relationship. Both leaf ABA and proline peaked under severe water stress. Lc showed higher accumulation of ABA and higher induction of the expression of both NCED and P5CS genes than Pz. Poly(ADP-ribose) polymerase increased during imposition of stress, mainly in Lc, and decreased under severe water stress. The two landraces hardly differed in their physiological performance. Under severe water stress, gs showed low sensitivity to ABA, which instead controlled stomatal closure under moderate water stress (gs > 0.15 mol·m-2 ·s-1 ). The prompt recovery after rehydration of both landraces confirmed their drought-tolerant behaviour. Differences between the two landraces were instead observed at biochemical and molecular levels.

Abstract
To deal with different kinds of DNA damages, there are a number of repair pathways that must be carefully orchestrated to guarantee genomic stability. Many proteins that play a role in DNA repair are involved in multiple pathways and need to be tightly regulated to conduct the functions required for efficient repair of different DNA damage types, such as double strand breaks or DNA crosslinks caused by radiation or genotoxins. While most of the factors involved in DNA repair are conserved throughout the different kingdoms, recent results have shown that the regulation of their expression is variable between different organisms. In the following paper, we give an overview of what is currently known about regulating factors and gene expression in response to DNA damage and put this knowledge in context with the different DNA repair pathways in plants. This article is part of a Special Issue entitled: Plant gene regulation in response to abiotic stress.

Abstract
Poly(ADP-ribose) polymerases (PARPs) and poly(ADP-ribose) glycohydrolases (PARGs) are the main enzymes responsible for the post-translational modification known as poly(ADP-ribosyl)ation. These enzymes play important roles in genotoxic stress tolerance and DNA repair, programmed cell death, transcription, and cell cycle control in animals. Similar impacts are being discovered in plants, as well as roles in plant-specific processes. In particular, we review recent work that has revealed significant roles for poly(ADP-ribosyl)ation in plant responses to biotic and abiotic stress, as well as roles for ADP-ribose pyrophosphatases (a subset of the nucleoside diphosphate linked to some moiety-X or NUDX hydrolases). Future challenges include identification of poly(ADP-ribosyl)ation targets and interacting proteins, improved use of inhibitors and plant mutants, and field-based studies with economically valuable plant species.

Abstract
Poly(ADP-ribosyl)ation is a posttranslational protein modification in which ADP-ribose (ADP-Rib) units derived from NAD(+) are attached to proteins by poly(ADP-Rib) polymerase (PARP) enzymes. ADP-Rib groups are removed from these polymer chains by the enzyme poly(ADP-Rib) glycohydrolase (PARG). In animals, poly(ADP-ribosyl)ation is associated with DNA damage responses and programmed cell death. Previously, we hypothesized a role for poly(ADP-ribosyl)ation in plant defense responses when we detected defense-associated expression of the poly(ADP-ribosyl)ation-related genes PARG2 and NUDT7 and observed altered callose deposition in the presence of a chemical PARP inhibitor. The role of poly(ADP-ribosyl)ation in plant defenses was more extensively investigated in this study, using Arabidopsis (Arabidopsis thaliana). Pharmacological inhibition of PARP using 3-aminobenzamide perturbs certain innate immune responses to microbe-associated molecular patterns (flg22 and elf18), including callose deposition, lignin deposition, pigment accumulation, and phenylalanine ammonia lyase activity, but does not disrupt other responses, such as the initial oxidative burst and expression of some early defense-associated genes. Mutant parg1 seedlings exhibit exaggerated seedling growth inhibition and pigment accumulation in response to elf18 and are hypersensitive to the DNA-damaging agent mitomycin C. Both parg1 and parg2 knockout plants show accelerated onset of disease symptoms when infected with Botrytis cinerea. Cellular levels of ADP-Rib polymer increase after infection with avirulent Pseudomonas syringae pv tomato DC3000 avrRpt2(+), and pathogen-dependent changes in the poly(ADP-ribosyl)ation of discrete proteins were also observed. We conclude that poly(ADP-ribosyl)ation is a functional component in plant responses to biotic stress.

Abstract
Poly(ADP-ribos)ylation is a reversible protein modification that in higher plants is catalyzed by two structurally different poly(ADP-ribose) polymerases, App and Zap. In vivo imaging of green-fluorescent protein (GPF) fusions showed that both Zap and App were associated with chromatin through the cell cycle progression. The in vivo behaviour of the App-GFP protein fusions can be attributed to the activity of two NASA motifs that mediate protein-protein interactions and nucleic acid binding. Expression of Zap deletion variants revealed that both Zn fingers and helix-turn-helix domains contributed to the association with chromosomes, whereas the localization in the nucleoplasm was mostly determined by the Zn fingers. The results highlight novel properties of protein sequences found in plant poly(ADP-ribose) polymerases and suggest important functions for this class of nuclear enzymes in chromosome dynamics.

Abstract
Poly(ADP-ribosylation) is a post-translational modification of nuclear proteins in response to DNA damage that activates the base excision repair machinery. Poly(ADP-ribose) polymerase which we will now call PARP-1, has been the only known enzyme of this type for over 30 years. Here, we describe a cDNA encoding a 62-kDa protein that shares considerable homology with the catalytic domain of PARP-1 and also contains a basic DNA-binding domain. We propose to call this enzyme poly(ADP-ribose) polymerase 2 (PARP-2). The PARP-2 gene maps to chromosome 14C1 and 14q11.2 in mouse and human, respectively. Purified recombinant mouse PARP-2 is a damaged DNA-binding protein in vitro and catalyzes the formation of poly(ADP-ribose) polymers in a DNA-dependent manner. PARP-2 displays automodification properties similar to PARP-1. The protein is localized in the nucleus in vivo and may account for the residual poly(ADP-ribose) synthesis observed in PARP-1-deficient cells, treated with alkylating agents or hydrogen peroxide.

Abstract
There is increasing evidence that the hypersensitive response during plant-pathogen interactions is a form of programmed cell death. In an attempt to understand the biochemical nature of this form of programmed cell death in the cowpea-cowpea rust fungus system, proteolytic activity in extracts of fungus-infected and uninfected cowpea plants was investigated, using exogenously added poly(ADP-ribose) polymerase as a marker. Unlike the proteolytic cleavage pattern of endogenous poly(ADP-ribose) polymerase in apoptotic animal cells, exogenously added poly(ADP-ribose) polymerase in extracts of fungus-infected plants was proteolytically cleaved into fragments of molecular masses 77, 52, 47, and 45 kDa. In vitro and in vivo protease inhibitor experiments revealed the activation of cysteine proteases, and possibly a regulatory role, during the hypersensitive response.

Abstract
In plants many biotic and abiotic stresses can cause secondary oxidative stress. Earlier work showed that, depending on the severity of the oxidative stress, plants can activate either cell protective genes or programmed cell death (PCD). Poly(ADP-ribose) polymerase (PARP) has been implicated as one of the enzymes in the apoptotic pathways induced by DNA damaging agents or oxidative stress. We show that in cultured soybean cells, PARP is involved in responses to mild and severe oxidative stresses, by mediating DNA repair and PCD processes, respectively. Addition of PARP inhibitors reduced the degree of cell death triggered by H2O2. Two windows of NAD consumption after H2O2 treatment were detected. Experiments with transient overexpression of Arabidopsis PARP cDNA promoted DNA repair and inhibited cell death caused by mild oxidative stress. However, following severe stress PARP overexpression increased cell death. Expression of antisense PARP produced the opposite effects: an increase in DNA nicks and inhibition of cell death at high, but not mild doses of H2O2.

Abstract
One of the immediate reactions of the mammalian cell to many environmental stresses is a massive synthesis of poly(ADP-ribose), catalyzed by poly(ADP-ribose) polymerase (PARP). Most of the biological functions attributed to PARP are inferred from experimentation with mammalian cells. In plants, the biology of PARP may be more complicated and diverse than was previously thought. Two poly(ADP-ribose) polymerase homologues were found in plants, the classical Zn-finger-containing polymerase (ZAP) and the structurally non-classical PARP proteins (APP and NAP), which lack the characteristic N-terminal Zn-finger domain. By enzymatic and cytological experiments the recombinant APP protein was shown to be located in the nucleus and to possess DNA-dependent poly(ADP-ribose) polymerase activity in yeast. The nuclear localization was further confirmed by the analysis of transgenic tobacco plants that expressed a translational gene fusion between APP and the bacterial beta-glucuronidase. The app promoter was transcriptionally up-regulated in cells pre-determined to die because of deficiency in a DNA ligase I.
