“…11, 16 We therefore overexpressed OsOSM1 gene in a mite-sensitive rice cultivar (Xudao 3) and knocked out the OsOSM1 gene in a mite-resistant rice cultivar (Nipponbare). 16 While OsOSM1 overexpressing lines presented a decrease in the number of mites per leaf, the lack of a functional OsOSM1 gene caused an increase in the number of mites per leaf, each compared with the corresponding WT line (Fig. 2), strongly suggesting that Osmotin1 protein is indeed involved in rice resistance to S. oryzae infestation.…”

“…Previous works detected two mite-resistant cultivars (IRGA 423 and Nipponbare) that could withstand or recover from herbivore injury. 11,16 These cultivars were able to maintain seed production under infested conditions, besides presenting lower levels of leaf damage and oxidative stress, and higher photosynthetic capacity than the mite-sensitive cultivars tested. Proteomic analyses indicated that both resistant cultivars presented high abundance of proteins related to plant defense and resistance mechanisms.…”

“…Interestingly, these cultivars presented higher abundance of defense-related Osmotin1 (LOC_Os12g38170) protein under infested conditions. 11,16 Osmotin and Osmotin-Like Proteins belong to the Thaumatin-Like Proteins of the pathogenesisrelated protein family 5 (PR-5), containing a typical thaumatin domain. 17 Osmotin is a multifunctional protein that acts as an osmoregulator (facilitating the compartmentation of ions or solutes) and provides plants with protection against pathogens, 18,19 exhibiting antifungal activities.…”

BACKGROUNDRice is one of the most consumed cereals in the world. Productivity losses are caused by different biotic stresses. One of the most common is the phytophagous mite Schizotetranychus oryzae Rossi de Simons (Acari: Tetranychidae), which inhibits plant development and seed production. The identification of plant defense proteins is important for a better understanding of the mite‐plant interaction. We previously detected a high expression of Osmotin1 protein in mite‐resistant rice cultivars, under infested conditions, suggesting it could be involved in plant defense against mite attack. Therefore, we aimed to evaluate the responses of three rice lines overexpressing Osmotin1 (OSM1‐OE) and three lines lacking Osmotin1 gene (osm1‐ko) to mite attack.RESULTSThe number of individuals (adults, immature stages, and eggs) were significantly lower in OSM1‐OE lines than those in wildtype (WT) plants. On the other hand, the osm1‐ko lines showed larger numbers of mites per leaf than WT plants. When plants reached the full maturity stage, two out of the three infested OSM1‐OE lines presented lower plant height than WT, while the three osm1‐ko lines (infested or not) presented higher plant height than WT. The reduction in seed number caused by mite infestation was lower in OSM1‐OE lines (12–19%) than in WT plants (34%), while osm1‐ko lines presented higher reduction (24–54%) in seed number than WT plants (13%).CONCLUSIONThese data suggest that Osmotin1 is involved in rice resistance to S. oryzae infestation. This is the first work showing increased plant resistance to herbivory overexpressing an Osmotin gene.This article is protected by copyright. All rights reserved.

“…Wild cotton plants under artificial defoliation by Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) larvae also showed low compensation for plant height in attack levels equal to or greater than 25% [ 72 ]. On the other hand, Schizotetranychus oryzae Rossi de Simons (Acari: Tetranychidae) mite infestation did not affect the height of rice plants ( Oryza sativa ) [ 73 ]. The height overcompensation for the Palha Roxa, São Pedro, and BM207 genotypes may reflect an important agronomic trait because plant height correlates with increased forage crop yield [ 74 ].…”

Insect pests such as Spodoptera frugiperda cause significant losses to maize (Zea mays mays). Control of S. frugiperda is difficult, but the use of insect resistant cultivars, including tolerant cultivars, is a promising alternative, and landraces are a potential source of insect resistance. This study investigated tolerance to S. frugiperda in five Brazilian landraces, Amarelão, Aztequinha, Branco Antigo, Palha Roxa, and São Pedro, in relation to one conventional (non-Bt) hybrid, BM207, under field conditions. We assessed tolerance as the ratio of insecticide-free to insecticide-protected plants for plant height, stem diameter, and leaf chlorophyll content at two plant stages. Tolerance ratios varied across the maize genotypes, but inconsistently across plant variables, and cluster analysis revealed three groups based on tolerance ratios. A first group contained genotypes similarly tolerant to S. frugiperda, BM207, Palha Roxa, São Pedro, and Aztequinha, while the second and third groups each contained single genotypes, Amarelão, and Branco Antigo, which were considered not tolerant. Overall, the landraces Palha Roxa, São Pedro, and Aztequinha compared favorably to BM207 in terms of tolerance, and therefore may be valuable for management of this pest, and as germplasm sources to improve tolerance in other cultivars.

“…Therefore, it is tempting to think that the selection of resistant cultivars against one stress factor would offer a multi-resistant cultivar suitable for cultivation under multiple environmental challenges. To name a few examples, the rice cultivar Nipponbare, exemplary for its post-attachment resistance to Striga hermonthica [ 31 ], was also shown to be resistant against Schizotetranychus oryzae (Acari: Tetranychidae) [ 85 ], but is salt sensitive [ 86 ]. Especially relevant to food securities are several drought-tolerant and Striga -resistant maize [ 87 ] and cowpea [ 88 ] cultivars.…”

Parasitic flowering plants represent a diverse group of angiosperms, ranging from exotic species with limited distribution to prominent weeds, causing significant yield losses in agricultural crops. The major damage caused by them is related to the extraction of water and nutrients from the host, thus decreasing vegetative growth, flowering, and seed production. Members of the root parasites of the Orobanchaceae family and stem parasites of the genus Cuscuta are among the most aggressive and damaging weeds, affecting both monocotyledonous and dicotyledonous crops worldwide. Their control and eradication are hampered by the extreme seed longevity and persistence in soil, as well as their taxonomic position, which makes it difficult to apply selective herbicides not damaging to the hosts. The selection of resistant cultivars is among the most promising approaches to deal with this matter, although still not widely employed due to limited knowledge of the molecular mechanisms of host resistance and inheritance. The current review aims to summarize the available information on host resistance with a focus on agriculturally important parasitic plants and to outline the future perspectives of resistant crop cultivar selection to battle the global threat of parasitic plants.
