Abstract: Okra (Abelmoschus esculentus) is a tropical vegetable cultivated widely in the Amazon region. In August 2016, typical anthracnose symptoms were observed on the leaves of okra in Altamira, Pará, Brazil with 60% disease incidence. Symptomatic leaf tissue were surface sterilized, rinsed with sterile water, and plated on potato dextrose agar. Colonies had greyish white aerial mycelium in 7-day-old cultures at 25±2 °C. Conidiophores were smooth-walled, septate. Conidiogenous cells were hyaline, straight, and 19×4 m. Appressoria were single, elliptical, and 8.5×6.5 m. The conidia were aseptate, cylindrical, with round apex and base, and 13×5 m. The isolated fungus was identified as Colletotrichum sp. The isolate was deposited in Culture Collection of Microorganisms (CMAA), Jaguariúna, Brazil (CMAA 1735). The isolate was further identified by sequencing the actin (ACT), chitin synthase (CHS1), beta-tubulin (TUB) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) genes (Damm et al. 2019). The sequences were deposited in GenBank (accession Nos. MK495949, MK495952, MK495951 and MK495950) and revealed over 98% identity with Colletotrichum plurivorum (MG747766, MG600847, MG600984 and MK862223). Reference sequences of C. orchidearum and C. magnum species complexes were used for the alignment and the phylogenetic analyses conducted using Bayesian method clustered the isolate in the clade corresponding to Colletotrichum plurivorum. The pathogenicity of the isolate was confirmed by spraying a suspension of conidia (1×106 mL1) on okra cv. Santa Cruz 47 with 46 leaves and the control plants were sprayed with distilled water. The plants were maintained in a dew chamber for 24 h under greenhouse at 27 °C with a 12-h-light/dark photoperiod. After 5 days, dark brown necrotic lesions were observed on the leaves of okra plants whereas control plants were all symptomless. The fungus was re-isolated, and showed the same morphological characteristics as the inoculated strain, fulfilling Kochs postulates. C. plurivorum has been reported to infect papaya (Sun et al. 2019) and cassava (Liu et al. 2019). To our knowledge, this is the first report of Colletotrichum plurivorum causing anthracnose on okra in Brazil.

The objective of this study was to evaluate pregnancy rates of recipients of different breed groups (Nellore and crossbreed), as well as the effects of size and type of the corpus luteum (CL) on plasmatic concentrations of progesterone and pregnancy rates of embryo recipients. A total of 152 heifers were synchronized with progesterone implants and on the day of embryo transfer, previously obtained by superovulation and frozen in ethylene glycol, the diameter and type of the corpus luteum (cavitary and compact) was measured and blood was collected for progesterone measurement. The pregnancy rate was 44.1%, with a diameter of corpus luteum higher in recipients that became pregnant (2.03±0.41) compared with nonpregnant ones (1.86±0.34 cm). Plasmatic concentrations of progesterone did not differ between pregnant (1.50±1.05) and non-pregnant (1.31±0.91 ng/mL) animals. The type of corpus luteum did not influence the pregnancy rates. Only Angus and crossbred Marchigiana differ among themselves in pregnancy rates (33.3 and 59.2%, respectively). The pregnancy probability was affected only by CL diameter, but not by P4 plasmatic concentration. Selection of the corpus luteum size at the time of embryo transfer is an important factor to increase pregnancy rates in recipients, and compact and cavitary corpora lutea do not influence the pregnancy rates of bovine embryo recipients. Nellore recipients have pregnancy rates that are satisfactory and comparable to crossbred (Bos taurus × Bos indicus) recipients.
