Description

Puccinia arachidis Speg. var. arachidis, Anales Soc. Ci. Argent. 17: 90 (1884)

Figure 5

Uredinia amphigenous, more abundant on the lower side of leaves, subepidermal, covered by the host epidermis when young, 0.5–1 mm diam., surrounded by chlorotic spot, green to yellowish spots on the upper side, first orange-brown, later brown. Urediniospores broadly ellipsoidal to ellipsoidal, (20–)24–28(–34) × (17–)19–23(–26) µm (n = 120), brown, wall 1–3 µm thick, echinulate, spines 1–2 µm long, 1–4 equatorial germ pores, pedicels up to 27 µm long. Telia not observed.

Two 28S rDNA sequences from two specimens of P. arachidis from Benin were obtained which together cover 633 base positions and differ at two base positions (similarity 631/633, i.e., 100%). They differ from previously published sequences of other rust fungi by 4% or 6% respectively. Barcode sequence data of P. arachidis are not available for comparison; they are published here for the first time.

Specimens examined: — Uredinia on Arachis hypogaea: BENIN. Atlantique: Allada, Sékou, elev. 19 m, 6°37’ N, 2°14’ E, 15 August 2017, A. Tabé and Y. Meswaet, TA405 (UNIPAR); Donga: Djougou, Pabégou, elev. 445 m, 9°42’ N, 1°39’ E, 11 September 2017, A. Tabé and Y. Meswaet, TA408 (UNIPAR), Acc. no. LSU: OL437025; Borgou: Parakou, Nima, elev. 376 m, 9°20’ N, 2°36’ E, 22 November 2018, A. Tabé, TA413 (UNIPAR), GenBank Acc. no. LSU: OL437026; Borgou: Parakou, Barrière, elev. 376 m, 9°20’ N, 2°36’ E, 27 August 2019, A. Tabé and Y. Meswaet, TA420 (UNIPAR).

Host and distribution in Benin: —Uredinia on Arachis hypogaea L. (Fabaceae), Northern and Southern Benin.

Host species:—Primary host species: Arachis glabrata Benth., A. hypogaea, A. nambyquarae Hoehne, A. prostrata Benth., Arachis sp.; Fabaceae (Farr & Rossman 2019). Secondary host species: not known.

Distribution: —Africa [Ivory Coast (Savary et al. 1988), Mauritius (Orieux & Felix 1968), Nigeria (Eboh 1981), Southern Africa (Crous et al. 2000), Tanzania (Ebbels & Allen 1979) Benin, Botswana, Burkina Faso, Ethiopia, Ghana, Kenya, Malawi, Mozambique, Senegal, Somalia, Sudan, Uganda, Zambia, Zimbabwe (Subrahmanyam et al. 1985)], Asia, Central America, North America, Oceania, Southern America, Caribbean (Farr & Rossman 2020).

Comments: —This is the second report of this rust for Benin. The morphological characteristics observed for specimens from Benin are identical with Puccinia arachidis as described from the other countries (e.g. Subrahmanyam et al. 1985, Hennen et al. 2005, Anco & Wang 2017).
