1 18 th Interna?onal Oil Palm Conference, Cartagena, Colombia Sebas&an Schornack University of Cambridge, Sainsbury Laboratory (SLCU) P. palmivora entering a leaf
2 Phytophthora sp. cause diseases in important crops Zoospore Host range narrow broader P. Infestans potato late blight P. ramorum sudden oak death University Davis P. sojae soybean root rot P. palmivora palm bud and cocoa fruit rot A. Dorrance (APSnet).
3 P. palmivora sporangia releasing zoospores Phytophthora palmivora is a cosmopolit In the tropics the most commonly encountered species is Phytophthora palmivora. P. palmivora diseases
4 Phytophthora palmivora causes oil palm bud rot Economically important hosts Oil palms Coconut Orchids Pineapple Rubber tree Durian Papaya Cocoa Citrus Picture: QuesadaLabNCSU
5 Phytophthora is a stealthy pathogen Biotrophy Necrotrophy
6 Phytophthora infec&on cycle Zoospore mycelia Sporangia and spores
7 P. palmivora forms haustoria in living plant cells Electron microscopy Light microscopy Fluorescence of a transgenic P. palmivora isolate
8 Microbes modify plant cell processes using secreted effector proteins SP RXLR effector domain effectors targets Alter plant cell processes fungus oomycete plant cell haustorium Help microbe colonize plant secreted by the pathogen into the host?ssue to bind to host proteins suppress host immunity, promote disease repertoire of effector- encoding genes varies significantly between Phytophthora isolates
9 Plant immunity: Plant resistance proteins recognise effectors effectors targets Alter plant cell processes fungus oomycete plant cell haustorium intracellular immune receptors effector- triggered immunity NB- LRR proteins recognise effectors or their ac?vi?es Are known NB- LRR proteins of other plants capable of detec?ng P. palmivora effectors?
10 Surveying effector resistance protein combina&ons Conserved Effector genes From pathogen MATCH! R gene candidates from oil palm genome Or Known R genes Expression in Nico:ana benthamiana using A. tumefaciens Wrong effector or wrong Resistance gene Effector + matching Resistance gene Limita&ons: R gene is func?onal in N. benthamiana, AVR and R gene are both cloned
11 P. palmivora belongs to a clade with no sequenced member species Phytophthora infestans (240 Mbp) - Solanum spp. P. palmivora (assumed < 90 Mbp) more than 200 hosts P. capsici (65 Mbp) - pepper, tomato, cucurbits P. sojae (95 Mbp) - soybean P. ramorum (65 Mbp) - various woody plants mul?locus phylogeny of Phytophthora from Blair et al Fungal Genet Biol
12 Genome sequencing of two P. palmivora isolates AJ LILI
13 Inden&fica&on of conserved effectors SP RXLR effector domain
14 It is beper to perceive early expressed effectors Early infec&on Late during infec&on
15 In the future: effector based resistance phenotyping AVRblb1 Avr3a AVR2 CRNs Blb (Rpi- blb1) Dms (R3a) Edn (Rpi- edn1) Snk (Rpi- snk1) Hjt (Rpi- hjt1) Sto (Rpi- sto1) Sto (Rpi- sto2)
16 R3a N. benthamiana is resistant to P. palmivora LILI (Colombia) Potato R3a transgenic tobacco Non- transgenic tobacco
17 R3a is effec&ve towards P. palmivora AJ (Indonesia) UV autofluorescence RFP merged WT R3a 3 dpi
18 Only one AVR3a variant is recognised by R3a AVR3a- EM Two alleles of AVR3a in Phytophthora infestans isolates SP RXLR Effector domain E M Potato R protein + R3a - R3a + INF1 (immunity triggering Phytophthora protein) AVR3a- KI K I
19 P. palmivora genome encodes AVR3a effectors P. Infestans (2) P. palmivora (9-15) P. Capsici (10) P. Sojae (2) P. Capsici (10)
20 RXLR effector domain R3a recognises some P. palmivora AVR3a variants Strong Weak None R3a HR Jus?ne Toulo,e

22 Expressed AVR3a variants evade recogni&on by R3a SP RXLR effector domain
