ZmXa21-L gene encodes a plant receptor-like kinases (RLKs) protein that enhances resistance to bacterial blight in rice
In this study, a full-length cDNA encoding a putative RLK protein with high sequence homology to the rice Xa21 gene was isolated from maize and designated as ZmXa21-L. The full-length cDNA of ZmXa21-L contained a 2796 bp open reading frame encoding a precursor protein of 932 amino acid residues. Comparative and bioinformatics analyses revealed that ZmXa21-L showed a high degree of homology with other Xa21-like proteins and contained the leucine-rich repeat domain, transmembrane region, and serine/threonine kinase domain. Subcellular localization revealed the presence of ZmXa21-L in the cell membrane. The expression level o...

Fusarium verticillioides FUM1 and FUM19 gene expression in maize kernels during early infection
Publication date: Available online 24 July 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Karlien van Zyl, Lindy J. Rose, Altus ViljoenAbstractFusarium verticillioides is the causal agent of Fusarium ear rot (FER), an economically important disease of maize worldwide. The fungus also produces fumonisins in maize grain, which poses a food safety concern. To better understand the molecular interactions between maize and F. verticillioides during infection, genes expressed in infected and healthy maize kernels have been investigated. The expression of fungal genes in grain during infection has, however, rec...

Seed priming induced blast disease resistance in finger millet plants through phenylpropanoid metabolic pathway
Publication date: Available online 19 July 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Savita Veeranagouda Patil, Belur Satyan KumudiniAbstractPhenylpropanoids contribute to all aspects of plant responses to biotic and abiotic stimuli. The lignin biosynthesis by phenylpropanoid pathway induces cell wall strengthening, a barrier against fungal penetration and progression. In the present study, two fluorescent Pseudomonas isolates JUPC113 and JUPW121 from cotton and wheat rhizospheres respectively were used for seed priming in greenhouse studies along with the unprimed seeds as control. Plants were asse...

A bidirectional promoter from Papaya leaf crumple virus functions in both monocot and dicot plants
Publication date: December 2019Source: Physiological and Molecular Plant Pathology, Volume 108Author(s): Anshu Alok, Siddharth Tiwari, Rakesh TuliAbstractThe intergenic region of Papaya leaf crumple virus (PaLCrV) transcribes the complementary (C) and virion (V) strand promoters, expressing the C1-C4 and V1-V2 genes respectively in opposite directions. Activities of the bidirectional promoter of PaLCrV in the C and V directions were compared with the 35S promoter of Cauliflower mosaic virus (CaMV35S), using β-glucuronidase (uidA) as the reporter gene. The resulting promoter constructs were named as pC, pV, and p35S respec...

Temporal expression of candidate genes at the Co-1 locus and their interaction with other defense related genes in common bean
Publication date: Available online 6 July 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Mahiya Farooq, Bilal A. Padder, Nadiem N. Bhat, M.D. Shah, Asif B. Shikari, Halima E. Awale, James D. KellyAbstractThe presence of multiple resistance genes in common bean and the diverse race spectrum of Colletotrichum lindemuthianum suggests that a broad spectrum of resistance mechanisms needs to be deployed in resistance breeding. However, limited studies on the interaction of anthracnose resistance genes and other plant defense genes exist in common bean. Therefore, we analyzed four candidate genes of Co-12 allel...

Tomato Solanum lycopersicum expressing the overlapping regions of three begomovirus genes exhibit resistance to Ageratum yellow vein Malaysia virus
We report the development of tomato lines showing resistance to Ageratum yellow vein Malaysia virus (AYVMV) a monopartite begomovirus and a causative agent for leaf curling, cupping, crinkling and stunting disease in the tomato cultivar MT1. The plants were transformed with a hp-RNAi construct “pHells-C1C2C3” consisting of overlapping regions of the C1, C2 and C3 genes of AYVMV. Progenies of two transgenic tomato lines (L132 and L18) exhibited resistance to AYVMV infection after inoculation with viruliferous whiteflies. The relative viral DNA accumulation levels at different times post inoculation were either not detec...
