Plants are equipped with various defensive attributes against herbivores, including volatile and nonvolatile compounds. In maize plants, benzoxazinoids mediate resistance against some herbivores, with the most abundant being (2R)-2-β-D-glucopyranosyloxy-4-hydroxy-7-methoxy-2H-1,4-benzoxazin3(4H)-one (DIMBOA-Glc), and its corresponding aglucone 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA). Both compounds have been shown to interfere in the larval development of generalist herbivores but are less effective on specialist, that is, grass-feeding, herbivores. Using a Brazilian population of Spodoptera frugiperda, we investigated (i) the level of constitutive benzoxazinoids in Neotropical maize genotypes, that is, Zapalote Chico, Mirt 2A, Sintético Spodoptera, L3, BRS 4103 and BRS 1040 (ii) the effect of S. frugiperda herbivory on benzoxazinoid levels in these genotypes and (iii) the impact of the genotypes on the development of S. frugiperda larvae. The results showed that the six maize genotypes produce different levels of benzoxazinoids, with Mirt 2A and BRS 1040 producing constitutively higher levels of HDMBOA-Glc and DIMBOA-Glc respectively compared to the other genotypes. When feeding on BRS 1040 and Mirt 2A, S. frugiperda larvae took an additional week to pupate, but this effect does not affect larval survival, what was the same and high on all the genotypes (>70%). Furthermore, production of DIMBOA-Glc and HDMBOA-Glc in these genotypes was suppressed, suggesting that S. frugiperda larvae can alter maize defence plant responses. In summary, our results demonstrate that Neotropical maize genotypes produce varying levels of benzoxazinoids, genotypes respond differently to S.frugiperda herbivory and S. frugiperda is able to cope with secondary metabolite-based defence in Neotropical maize.

Minc03328 effector gene downregulation triggered by in planta RNAi strategy strongly reduced plant susceptibility to Meloidogyne incognita and suggests that Minc03328 gene is a promising target for the development of genetically engineered crops to improve plant tolerance to M. incognita. Meloidogyne incognita is the most economically important species of root-knot nematodes (RKN) and causes severe damage to crops worldwide. M. incognita secretes several effector proteins to suppress the host plant defense response, and manipulate the plant cell cycle and other plant processes facilitating its parasitism. Different secreted effector proteins have already been identified in M. incognita, but not all have been characterized or have had the confirmation of their involvement in nematode parasitism in their host plants. Herein, we characterized the Minc03328 (Minc3s00020g01299) effector gene, confirmed its higher expression in the early stages of M. incognita parasitism in plants, as well as the accumulation of the Minc03328 effector protein in subventral glands and its secretion. We also discuss the potential for simultaneous downregulation of its paralogue Minc3s00083g03984 gene. Using the in planta RNA interference strategy, Arabidopsis thaliana plants overexpressing double-stranded RNA (dsRNA) were generated to specifically targeting and downregulating the Minc03328 gene during nematode parasitism. Transgenic Minc03328-dsRNA lines that significantly downregulated Minc03328 gene expression during M. incognita parasitism were significantly less susceptible. The number of galls, egg masses, and [galls/egg masses] ratio were reduced in these transgenic lines by up to 85%, 90%, and 87%, respectively. Transgenic Minc03328-dsRNA lines showed the presence of fewer and smaller galls, indicating that parasitism was hindered. Overall, data herein strongly suggest that Minc03328 effector protein is important for M. incognita parasitism establishment. As well, the in planta Minc03328-dsRNA strategy demonstrated high biotechnological potential for developing crop species that could efficiently control RKN in the field.
