I am looking for a peer review of Sudden Oak Death - Discussion. Would appreciate comments. (a Mentally Efficient Loonies And Nice Insane Elephants creation 21:20, 11 February 2007 (UTC)). alpina Bregant, Montecchio and Linaldeddu (2020)[reply]

Below you "ll find the publicatio of phytophthora alpina. Bregant C, Sanna GP, Bottos A, Maddau L, Montecchio L, Linaldeddu BT. 2020. Diversity and pathogenicity of Phytophthora species associated with declining alder trees in Italy and description of Phytophthora alpina sp. nov. Forests 11 (8): 848.

Hierarchical nomenclature[edit]

On 3 February 2007 User:Werothegreat changed | regnum = Stramenapila to | domain = Eukaryota and | phylum = Heterokontophyta or Oomycota to | unranked_phylum = Chromista without discussion or citing authority for the change. --Bejnar 23:45, 3 February 2007 (UTC)[reply]

PTA[edit]

"Phytophthora taxon Agathis" (PTA) has been discussed in the non-scientific literature as the causative agent for the plant disease otherwise known as "kauri dieback" or "kauri rot". See, e.g., "Kauri Dieback in Auckland Caused by Phytophthora" New Zealand Plant Conservation Network. PTA is not a proper species name, see Binomial nomenclature and Ternary name. The kauri's formal name is: Agathis australis, hence PTA is the Phytophthora that attacks kauris (taxon Agathis). I haven't yet found the original paper that identifies the disease as one of the Phytophthora. --Bejnar (talk) 04:11, 3 February 2009 (UTC)[reply]

There's a paragraph at the end of Agathis australis#Conservation, which would be one good place to put any more definitive information that people can find. Here's a brief description of why they are using such a strange name:

The organism was first identified as P. heveae (Gadgil 1974), but the recent revolution in Phytopthora taxonomy warrants a reexamination of its affinities. While our molecular studies (Fig 6) confirm it is related to this species, they suggest it is more closely related to P. katsurae, and indeed has an identical ITS sequence to an authentic strain of this species (ICMP 16915). However it differs from P. katsurae in the strict sense in its smooth, as opposed to strongly bullate (blister-like), oogonia (Fig 6). We propose that PTA is an as yet unnamed species. Further, we suggest that it is introduced to New Zealand, in view of its relatively recent recognition and the cultural and ITS sequence similarity of isolates recovered to date.[1]

Leek Photograph[edit]

The article states that Phytophthora infect dicotyledons primarily, yet the only photograph shows a leek, which is a monocot. Can anyone supply a photo of a common victim, such as an ericaceous plant?Carlaclaws (talk) 02:17, 16 May 2009 (UTC)[reply]

Added photo: Sudden Oak Death caused by Phytophthora ramorum to article. I like the leek photo. --Bejnar (talk) 17:31, 17 May 2009 (UTC)[reply]

I like the leek photo, too, and I think it should remain, but I thought a picture of a woody dicot would be very helpful. Thanks.Carlaclaws (talk) 23:16, 17 May 2009 (UTC)[reply]
