Abstract

Viruses and viroids cause several diseases in tomato (Solanum lycopersicum) worldwide, generating important economic losses. About 312 viruses and seven viroids have been associated, of which more than 28 are present in Mexico. Therefore, the use of Plant Growth-Promoting Rhizobacteria (PGPR) can be an effective alternative for the management of viruses and viroids. The genera Pseudomonas, Bacillus, Azospirillum, Anabena and Stenotrophomonas have been implemented against main viruses reported in tomato: Cucumber mosaic virus (CMV), Tobacco mosaic virus (TMV), Tomato chlorotic spot virus (TCSV), Tomato mottle virus (ToMoV), Tomato spotted wilt virus (TSWV), Tomato yellow leaf curl virus (TYLCV), Potato virus Y (PVY), Groundnut bud necrosis virus (GBNV), with benefits in decreased incidence and severity up to 80 % and yield increase over 40 %. In Mexico, only Bacillus has been used. The use of PGPR is a strategy that could mitigate the impact of viral and viroid diseases and can be integrated into integrated management.

番茄（Solanum lycopersicum）中的病毒和病毒病，以及作为管理替代办法的植物生长促进根瘤菌

病毒和病毒病在全球番茄（Solanum lycopersicum）中引发多种病害，造成重大经济损失。大约有 312 种病毒和 7 种病毒病，其中超过 28 种存在于墨西哥。因此，使用植物生长促进根瘤菌（PGPR）可以有效地替代病毒和病毒。假单胞菌属、芽孢杆菌属、Azospirillum 菌属、Anabena 菌属和 Stenotrophomonas 菌属已被用于防治番茄中报告的主要病毒：黄瓜花叶病毒 (CMV)、烟草花叶病毒 (TMV)、番茄萎黄斑点病毒 (TCSV)、番茄斑驳病毒 (ToMoV)、番茄斑点枯萎病病毒 (TSWV)、番茄黄叶卷曲病毒 (TYLCV)、马铃薯病毒 Y (PVY)、落花生芽坏死病毒 (GBNV)。墨西哥只使用了芽孢杆菌。使用 PGPR 是一种可减轻病毒和病毒病影响的策略，可纳入综合管理。
