“…In addition to salinity, diseases caused by phytonematodes are also an important problem for cultures worldwide, highlighting the species of the genus Meloidogyne Goeldi. In Brazil, among the several species of root-knot nematode that have already been identified in the northeast region, there is the highlight for M. enterolobii Yang and Eisenback, commonly associated with the losses caused in the guava tree (Psidium guajava L.) (Castro, 2019;Cavalcanti et al, 2021). In addition to this fruit, this pathogen has a wide range of hosts, including grain-producing crops, such as cowpea (Castro, 2019;Guimarães et al, 2003), already registered Fabaceae associated with Meloidogyne spp.…”

Cowpea, Vigna unguiculata (L.) Walp, is a very important Fabaceae in the diet of families in the northeast region of Brazil. This plant species is among the different cultures affected by the root-knot nematode. In this region, in addition to phytonematodes, another condition that affects cowpea productivity is salinity, one of the main abiotic limiting factors. The cultivar Pitiúba, however, has good adaptability to salt stress conditions. However, information on the behavior of root-knot nematodes in an environment with high levels of salinity for this crop is still scarce. Based on the above, the objective of this work was: 1) to evaluate the hatchability of J2 of Meloidogyne enterolobii in 100mM NaCl solution; 2) evaluate the motility and infectivity of J2 of M. enterolobii in saline solution at the levels of 0, 25, 50, 75, 100, 125, 150, 175, 200, 300, and 400mM; 3) to investigate the impairment of the development of M. enterolobii in cowpea Pitiúba under irrigation with NaCl solution at 100mM. It was found that J2 hatching, motility, and infectivity of juveniles of M. enterolobii were not affected by the levels of salinity tested in vitro. In Pitiúba, irrigation with 100 mM saline solution considerably affected the development of juveniles of the pathogen in the roots.

Background and Aims Psidium is the 4th largest genus of Myrtaceae in the Neotropics. Psidium guajava is widely cultivated in the tropics for its edible fruit. It is commercially under threat due to the disease guava decline. P. cattleyanum is one of the 100 most invasive organisms in the world. Knowledge of the phylogenetic relationships within Psidium is poor. We aim to provide a review of the biology, morphology and ecology of Psidium, a phylogenetic tree, an infra-generic classification and a list of species. Methods Morphological and geographic data were obtained by studying Psidium in herbaria and in the field between 1988 and 2020. Forty-six herbaria were visited personally. A database of c. 6,000 specimens was constructed, and the literature was reviewed. Thirty species (c. 1/3 of the species in the genus) were sampled for molecular phylogenetic inference. Two chloroplast (psbA-trnH and ndhF) and two nuclear (ETS and ITS) regions were targeted. Phylogenetic trees were constructed using Maximum Likelihood (ML; RaxML) and Bayesian Inference (BI; MrBayes). Key Results Psidium is a monophyletic genus with four major clades recognized as sections. Section Psidium (ten species), to which P. guajava belongs, is sister to the rest of the genus; it is widespread across the Neotropics. Section Obversifolia (six species; restricted to the Brazilian Atlantic Forest), which includes P. cattleyanum, is sister to the innermost clade composed of sister sections Apertiflora (31 species; widespread but most diverse in the Brazilian Atlantic Forest) + Mitranthes (26 species; widespread in dry forests and probably diverse in the Caribbean). Characters associated to diversification within Psidium are discussed. Conclusions Research on prefoliation, colleters, leaf anatomy, leaf physiology, staminal development, placentation, and germination associated to the anatomy of the opercular plug is desirable. Studies are biased towards sections Psidium and Obversifolia, with other sections poorly known.
