Mexico ranks second in the world for Persian lime () exports, making it the principal citrus exporter within the national citrus industry, exporting over 600,000 tons per year. However, diseases are the main factor reducing production, resulting in significant economic losses. Among these diseases, fungal diseases like dieback, caused by species of , are an emerging issue in Persian lime.

Huanglongbing (HLB) is a vascular disease of caused by three species of the α-proteobacteria " Liberibacter", with " Liberibacter asiaticus" (Las) being the most widespread and the one causing significant economic losses in citrus-producing regions worldwide. However, Persian lime ( Tanaka) has shown tolerance to the disease. To understand the molecular mechanisms of this tolerance, transcriptomic analysis of HLB was performed using asymptomatic and symptomatic leaves.

(rosy trumpet) is an economically important neotropical tree in Mexico that is highly valued for the quality of its wood, which is used for furniture, crafts, and packing, and for its use as an ornamental and shade tree in parks and gardens. During surveys conducted in the lower Balsas River Basin region in the states of Guerrero and Michoacán, symptoms of floral malformation were detected in trees. The main objectives of this study were to describe this new disease, to determine its causal agent, and to identify it using DNA sequence data.

Article Synopsis
  • Fusarium pseudocircinatum is identified as the primary cause of big-leaf mahogany malformation disease (BLMMD) in mahogany trees in Mexico, significantly impacting this valuable timber species.
  • The study assessed genetic diversity among F. pseudocircinatum isolates collected from 611 mahogany trees across four Mexican states, finding high overall genetic variability with 87 unique multilocus genotypes identified.
  • The high genetic diversity (average 0.147) and significant variation within genotypes suggest ongoing genetic flow and possible historical dispersion routes, particularly between isolates from Colima and Michoacán.

Article Synopsis
  • An oomycete plant pathogen affects a variety of plants and is particularly harmful to chili pepper crops worldwide.
  • The research aimed to enhance the genome resources related to this pathogen.
  • Six different isolates of the pathogen were sequenced from Mexico to contribute to the understanding of its diversity.

Article Synopsis
  • * Researchers obtained 61 isolates (32 from mango and 29 from mahogany) and used 14 internal simple sequence repeat (ISSR) primers, ultimately selecting 5 that showed the most variation, producing 49 polymorphic bands.
  • * Results revealed significant genetic variability among the isolates based on the host plant (43%), less so between mango and mahogany isolates (34%), indicating that the host of origin has a greater impact on genetic diversity than geographic location.
