An n incomplete e understand ding of zinc homeostasiis mechanisms in plantss is howeverr a limitation.. Recently th e first transc cription factorrs regulatingg zinc homeo ostasis in Ara abidopsis we ere identified d (Assunção et al. 2010).. The AtbZIP P19 and AtbZ ZIP23 were shown s to be essential for the adaptattion to zinc d deficiency. Trranscript profiling revealeed only a small set of ge enes, to be induced in wild-type p lants in response to zinc deficienccy, but not in the bzip1 19bzip23 Ara abidopsis double mutant line.

CC8 8 – Manu uela Costta A molecu ular antago onism tha at shapes the t flowerr BioFIG G, Departmen nt of Biology, Faculty F of Scie ences, Univers sity of Porto The a action of anttagonistic pro oteins on the e transcriptio onal activity of developm mental key genetic progrrammes is an important regulatory m mechanism in n the genera ation of differrent morpho ologies that ccharacterise multicellular organisms. In An ntirrhinum majus, m the do orsoventral asymmetry of the flowe ers is estabblished throu ugh a moleccular antago onism involv ving two MY YB-like transcription fac ctors, RADIA ALIS (RAD)), and DIVA ARICATA (DIV). RAD is expressed e do orsally in the floral primorrdia and prom motes dorsal petal identiity, whilst DIV is expressed in the wh hole floral primordia, desp pite having a phenotypic effect only in more ven ntral regions of the flowe er. Genetic and a molecular studies hhave revealed that RAD antagonisess the activitty of DIV th hrough an in ndirect intera action with another MY YB-like prote ein identified on a yeastt two-hybrid screen using RAD as bait (DRIFss, DIV and RADintera acting protein ns). www.mapp.edu.pt/bioplant 7 4ª Workkshop Anual Biioplant 18 / 19 Julho 2013 To be etter understtand the role of the DRIF F proteins in the t molecula ar antagonism m that RAD exerts over DIV function, the DNA--binding actiivity of DIV was analysed by gel-shhift assays in the prese ence of the DRIF D and RA AD proteins. The subcellular co-localisation of theese three prroteins was determined using fluore escent tagge ed proteins in i transient assays in toobacco epid dermal cells. The expresssion pattern of the DRIF genes was analysed by y RT-PCR annd the evolutionary historry of these new MYB-like e proteins stu udied by phylogenetic analysis. Our rresults sugge est that the molecular an ntagonism th hat RAD has s over DIV iss mediated by b the DRIF F proteins. In the ventral domain of th he flower DIV V and DRIFs s interact insside the nucle eus in orderr to determin ne the ventra al identity. H owever, in the dorsal do omain, wheree RAD is pre esent, RAD interacts witth the DRIF in i the cytopla asm and pre events their nuclear n localiisation, preventing DIV ffrom interactting with the RIPs, which h results in flower f dorsal identity. Thhese results along with tthe fact that the DRIF, RAD R and DIV V proteins are a present in such a vaariety of land d plant speciies, suggest that this mo odule of interractions may y have been implicated inn a broader set of functiions throughout plant evo olution. 9 – Franc cisco Peiixoto CC9 Major Rese earch Topics at CITA AB CITAB B/UTAD CITA AB research is focused on o the agro-ffood and forrestry system ms using thee production--chain appro oach as a whole. w This Research Unit is com mposed by a multidiscipplinary team m with experrtise ranging g from funda amental scie ences such as a biology and a chemistrry to agrono omists, foresttry engineerss and ecolog gists.

Living g organisms are subjecte ed to consta antly changin ng environme ents that com mpromise survival. As se essile organisms, plants have optimiized a myria ad of strategies to adaptt, avoid or to olerate stresss conditions.. A general type of mech hanism assoc ciated to env vironmental rresponses is s posttranslational mod dification (PT TM), which a acts as a fas st and revers sible regulatoor of key pro oteins. Relevvant PTMs includes sma all peptides such as ubiquitin and ubiquitin-like modifiers, namely the S Small Ubiquittin-like Modiffier (SUMO) . SUMO ma ay exert different effects depending on o the targe et protein, either e controlling its con nformation, or o even cre eating or bloocking interracting interffaces that ultimately modulate its activvity. SUMO attachment a or o sumoylatioon requires SUMO S peptid des to first be b processed d by SUMO p proteases (U ULP/SENP fa amily), and tthen conjuga ated to a targ get’s lysine via v SUMO E1 activase a and SUMO E2 E conjugase e, aided by S SUMO E3 lig gases. Deco onjugation of the SUMO peptide can subsequently be carried d out by the SUMO prote eases. A gre eat number of SUMO ta argets are in nvolved in nuclear-relate n ed functionss, and are part p of essen ntial cellular processes. This is particcularly evide ent in plants since loss-of of-function mutants of m most SUMO componentts display embryonic lethality or pleiotropic defects. SUMOconju ugation levelss vary in res spect to grow wth condition ns, tissues an nd developm mental stages s. It is there efore expecte ed that highly dynamic S SUMO conjugation and deconjugatio d on machinery y is at play. Unlike ubiqu uitin, SUMO conjugation machinery components c are less abuundant in the e plant genome. SUMO proteases (ULPs) consttitute a fairly y large gene e family andd are the potential sourcces of specifficity within the t pathwayy by displayin ng different enzymatic aactivity, subcellular localization and expression levels. Base ed on a reverse genettics strategyy, several se ets of Arabiidopsis ULP T-DNA inse ertion mutan nts have bee en characterrized.

For th his study, pla ants of both species, col lected togeth her with the sediment invvolving their roots, were placed in ve essels and maintained m in n greenhous ses, exposed d to natural eenvironmenta al and light conditions. A nutritive saline s solutio on was add ded to all ve essels throu gh an autom mated irrigattion system (2 daily cyc cles of flood / draught) to t mimic the e tides and m maintain pla ants at optim mum nutrition nal condition ns. After 2 w weeks of acclimation, all vessels weere spiked with w a saline e Cd solution n, which was s in contact w with the plantt rhizosphere e for about 6hh.

For that, plants above eground tisssues were se eparated from m belowgrou und structures, which in tturn were carefully separrated from the t sediment. Cadmium was determ mined as beffore [1]. Ressults sugges st that both plants werre able to accumulate considerab ble amounts s of Cd, esspecially in their below wground tissu ues, without showing sig gns of toxicity y. The additio on of the miccrobial conso ortium seem med to prom mote Cd tran nslocation to o P. australlis stems, in ncreasing thhe phytoextrraction poten ntial of this plant. In ad ddition, the phytostabiliz zation potenttial of J. maaritimus was s also enhanced.

Most studies oon Cr phytoto oxicity are b based on the e Cr(VI) valen nce, while C Cr(III) effects remain less studied. On e of the mos st well studie ed crops for Cr(VI) toxicity is Lactuca a sativa, a worldwide con nsumed cropp, and an exc cellent mode el in ecotoxiccology.

These e defence strategies s re esulted in the production n of a signiificant divers sity of secon ndary metab bolites, which h have attractted scientists s’ attention in n the past few w years. The e edible brown n seaweed Fucus F spiraliis Linnaeus is widely dis stributed oveer the Portug guese west coast. This species is rich in second dary metabolites, among which fatty acids constiitute a very special group. Fatty acid ds are one o of the most re epresentative e classes off compounds s, both in divversity and contents, c and d are associa ated with div verse biological activitiess. F. spiralis has a diversse lipid composition, dom minated by m mono and po olyunsaturate ed long chainn fatty acids, oleic acid being the major one [1].

Neverthelesss, there are several pestts that can deestroy its cultures, such as Spodop ptera littoralis s (Bois.).

The meetabolic profile of severral S. littoraliis materials (larvae, ( pupa ae, adults an nd excrements) and the hhost plant ma aterial (leave es) were ch haracterized in terms o f phenolics, alkaloids, amino a acidss, fatty acids s and sterols. These me etabolites we ere determin ned by HPLC C-DAD and GC-MS G techhniques. Phe enolics were identified only in L. esc culentum lea aves, being absent in S. S littoralis m materials. Ste eroidal alkalo oids were ide entified in all matrices, e especially in leaves and S. S littoralis exxcrements. Amino A acidss and fatty accids seem to be bioaccum mulated by S. S littoralis larrvae. The antioxidant capacity of these matr ices was ch hecked in chemical miccroassays against severral reactive species (Fig gure 1). The e ethanolic extract e from tomato leavves was the most active e antioxidantt, followed by y that of S. litttoralis excre ements. Figurre 1.

As verified for the antioxiidant potenttial, the tom mato leavess and S. litttoralis excre ements were e the most active a matrice es. Their ac ctivity can be e associatedd to the conttent in steroidal alkaloids.
