“…Fungi are responsible for several diseases that attack plants causing damages in various important crops, decreasing their productivity (Mandal et al, 2013;Labandeira and Prevec, 2014). Furthermore, the chemical control used as strategy in combating fungal diseases is associated with toxic and hazardous effects on the environment and nontarget organisms (Meng et al, 2010;Marei et al, 2012;Yadav et al, 2013).…”

Mo-CBP3 is an antifungal protein produced by Moringa oleifera which has been investigated as potential candidate for developing transgenic crops. Before the use of novel proteins, food safety tests must be conducted. This work represents an early food safety assessment of Mo-CBP3, using the two-tiered approach proposed by ILSI. The history of safe use, mode of action and results for amino acid sequence homology using the full-length and short contiguous amino acids sequences indicate low risk associated to this protein. Mo-CBP3 isoforms presented a reasonable number of alignments (>35% identity) with allergens in a window of 80 amino acids. This protein was resistant to pepsin degradation up to 2 h, but it was susceptible to digestion using pancreatin. Many positive attributes were presented for Mo-CBP3. However, this protein showed high sequence homology with allergens and resistance to pepsin digestion that indicates that further hypothesis-based testing on its potential allergenicity must be done. Additionally, animal toxicity evaluations (e.g. acute and repeated dose oral exposure assays) must be performed to meet the mandatory requirements of several regulatory agencies. Finally, the approach adopted here exemplified the importance of performing an early risk assessment of candidate proteins for use in plant transformation programs.

“…During the Permian, evidence of surface feeding is rare to absent in virtually all floras examined, but when present, has been found to occur on seed plants such as medullosans, gigantopterids, callipterid peltasperms, and taeniopteroid cycadophytes (Beck and Labandeira, 1998;Vasilenko, 2007;Prevec et al, 2009;Labandeira, 2012;Labandeira and Prevec, 2014;Schachat et al, 2014). The variety of surface-feeding damage increases markedly during the Middle Pennsylvanian and through the early Permian to include approximately ten DTs that collectively indicate an expansion of morphologies, autecologies, and behaviors associated with feeding on epidermal and immediately underlying tissues.…”

“…A somewhat broader spectrum of margin feeding occurs overwhelmingly on glossopterid hosts, from Permian, glossopterid-dominated floras of various regions in Gondwana (Plumstead, 1963;Prevec et al, 2009;Cariglino and Gutiérrez, 2011;Pinheiro et al 2012;Slater et al, 2012;Labandeira and Prevec, 2014;Gallego et al 2014), and also from a broader spectrum of hosts from Permian Euramerica (Beck and Labandeira, 1998;Vasilenko, 2007;Labandeira and Allen, 2007;Schachat et al, 2014).…”

“…Apparently, no hole feeding is recorded from any Pennsylvanian-age flora. Several holefeeding DTs occur sporadically throughout the Permian, from floras of Euramerica (Beck and Labandeira, 1998;Vasilenko, 2007;Labandeira and Allen, 2007;Labandeira, 2012), Gondwana (Gallego et al, 2003;Prevec et al, 2009;Cariglino and Gutiérrez, 2011;Slater et al, 2012;Pinheiro et al, 2012;Labandeira and Prevec, 2014;Gallego et al, 2014), and Cathaysia (Glasspool et al, 2003).

“…Ovipositional damage is first recognized during the middle Pennsylvanian, as large, lenticular lesions in calamite and other sphenopsid stems (Béthoux, 2004) and during the late Pennsylvanian as lenticular lesions on an unidentified leaf (Laaß and Hoff, 2014). The predominance of oviposition on plant axes continues throughout the Permian (Labandeira, 2006a(Labandeira, , 2006b), but largely becomes supplemented by foliar oviposition, particularly on Gondwanan, glossopterid-based floras (Prevec et al, 2009;McLoughlin, 2011;Pinheiro et al, 2012;Labandeira and Currano, 2013;Labandeira and Prevec, 2014;Gallego et al, 2014).…”

The Mitchell Creek Flats locality (MCF) contains a flora from the early Permian (Cisuralian) of north-central Texas that has been qualitatively and quantitatively evaluated for insect herbivory.The level of herbivory is average for a middle Cisuralian flora from this region, although there is a relatively modest number of specimens. Three ecological features of this deposit are noteworthy in the context of the larger plant-insect interaction trends that have been studied across the region. First is a well-balanced distribution across the MCF flora of the five functional feeding groups (FFGs) of external foliage feeding, piercing and sucking, oviposition, galling, and seed predation. These five FFGs encompass 22 discrete insect-mediated damage types (DTs) that indicate a variety of generalized and specialized herbivory. Second is the elevated incidence and diversity of seven gall DTs, indicating an arid environment. Third is the pattern of opportunistic herbivory on the cycadophyte Taeniopteris spp., the single, overwhelmingly dominant host that represents 47.5% of all foliage, 56.9% of all interactions, and 16 of the 22 DTs. This distribution of insect-mediated damage suggests a diverse community of opportunistic, generalized and specialized insect herbivores, including a guild of xeric-adapted gallers engaged in a variety of feeding styles that overwhelmingly targeted Taeniopteris spp. as a host plant. This characterization is consistent with an opportunistic herbivory strategy and supports Feeny's apparency hypothesis, in which the most conspicuous, accessible plant at a site is disproportionately and most extensively herbivorized. Highlights:The early Permian was a critical period in insect evolution.We examined a fossil flora from the early Permian of Texas for insect herbivory.Insects overwhelmingly preferred the most abundant plant taxon.Galling, an advanced behavior indicative of an arid environment, was very common.
