Resistance to Meloidogyne incognita, Meloidogyne javanica and Pratylenchus brachyurus in sunflower cultivars adapted to the tropical region of Brazil
Tropical Plant Pathology - Tập 41 - Trang 325-330 - 2016
The continuous soybean-maize crop succession in the tropical region of Brazil has led to significant increases in the population size of root-knot (Meloidogyne incognita and M. javanica) and root-lesion nematodes (Pratylenchus brachyurus), which make soils unsuitable for soybean cropping. A greenhouse study was conducted to identify sunflower genotypes adapted to the tropical region of Brazil and ...... hiện toàn bộ
QTL and eQTL mapping associated with host response to Candidatus Liberibacter asiaticus in citrandarins
Tropical Plant Pathology - Tập 45 - Trang 626-645 - 2020
Huanglongbing (HLB) is a severe disease of citrus caused by the bacterium Candidatus Liberibacter. In America, the most common species is Candidatus Liberibacter asiaticus (CLas). In a previous study of the Citrus-HLB pathosystem, our group found differences in CLas multiplication in a population of hybrids obtained by hybridization between Citrus sunki Hort. Ex Tan. and Poncirus trifoliata (L.) R...... hiện toàn bộ

Plant parasitic nematode assemblages associated with sweet potato in Kenya and their relationship with environmental variables
Tropical Plant Pathology - Tập 42 - Trang 1-12 - 2016
Sweet potato is one of the most important staple food crops consumed in Kenya and throughout Africa but yields are greatly reduced by plant parasitic nematodes (PPN). The aim of this study was to determine the prevalence of PPN in Kenyan sweet potato fields and their relationship with soil and climatic variables. Soil samples were collected from sweet potato fields in Busia, Teso, Kisii, Embu and ...... hiện toàn bộ
ISSR primers for analysis of genetic variability of Stenocarpella maydis
Tropical Plant Pathology - Tập 41 - Trang 270-275 - 2016
Although stalk and ear rot is a major disease affecting corn plants, little is known regarding the genetic variability of Stenocarpella maydis, its main causal agent. In this study, we evaluated inter-simple sequence repeat (ISSR) primers for analysis of genetic variability of the pathogen. For DNA analysis, six isolates of S. maydis were amplified using 42 ISSR primers. Polymorphic information co...... hiện toàn bộ

Glutamate potentiates rice resistance to blast
Tropical Plant Pathology - Tập 45 - Trang 136-142 - 2020
Leaf blast, caused by the hemibiotrophic fungus Pyricularia oryzae, is the most important disease affecting rice production worldwide. The present study investigated the potential of using glutamate (Glu) to increase rice resistance to leaf blast. Rice plants (cultivar Metica-1) were non-supplied (−Glu) or supplied (10 mM) (+Glu) with Glu and non-inoculated or inoculated with P. oryzae. Leaf blast...... hiện toàn bộ
Distribution of parasitic nematodes in Kenyan rice fields and their relation to edaphic factors, rainfall and temperature
Tropical Plant Pathology - Tập 43 - Trang 128-137 - 2017
Rice is the third most important crop in Kenya after maize and wheat. Plant parasitic nematodes (PPN) are a major rice production constraint. The objective of this study was to determine the distribution and abundance of rice PPN in Kenya and their association with environmental variables. Soil and plant samples were collected from rainfed upland and irrigated lowland rice fields in Kirogo, Thiba,...... hiện toàn bộ
Unravelling the complexity of maize resistance to bacterial and fungal diseases: an integrative perspective
Tropical Plant Pathology - Tập 47 - Trang 332-352 - 2022
Maize is one of the most important cereals for both human and animal nutrition, and diseases that affect the crop pose a major threat to global food security. Breeders are racing against time to develop genotypes resistant to diseases, which is the most sustainable management strategy. A deep understanding of maize pathogens, plant-pathogen interactions, the different layers of maize defenses, as ...... hiện toàn bộ
