Given the aphids high reproductive capacity, assessing their biocontrol by using entomopathogenic fungi is crucial; to determine their potential, fungi were tested in planta and in field conditions. Significant decrease of Myzus persicae (Sulzer) population was observed in planta after applying Beauveria bassiana (strain 7R), Trichoderma gamsii (strain Z) or Metarhizium brunneum (strain Meta Br1) at 1 × 10 or 1 × 10 conidia/mL on pepper plants. Significant differences of aphids' populations were detected between fungus concentration and control (F = 68.

One of the most important photosynthetic components, sensible to hydric stress, is maximum quantum yield for photosystem II (PSII, or Fv/Fm).

Maize is the most important crop around the world and it is highly sensitive to abiotic stress caused by drought, excessive salinity, and extreme temperature. In plants, trehalose has been widely studied for its role in plant adaptation to different abiotic stresses such as drought, high and low temperature, and osmotic stress. Thus, the aim of this work was to clone and characterize at molecular level the trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP) genes from maize and to evaluate its differential expression in maize seedlings under drought stress.

Article Synopsis
- Environmental risk assessment (ERA) evaluates whether genetically modified (GM) crops, specifically insect-resistant and herbicide-tolerant maize hybrids, could pose increased pest potential or environmental harm compared to conventional maize.
- Studies conducted across five ecoregions in Mexico from 2009-2013 showed no significant differences in aspects like stand count and lodging between GM hybrids and conventional maize, indicating minimal ecological risks.
- While some phenotypic differences were noted in seedling vigor and grain characteristics, these differences are not expected to lead to ecological risks, suggesting that the GM hybrids can effectively protect crops from insect damage without additional environmental concerns.
Article Synopsis
- Mexico is taking action to preserve its maize varieties and minimize gene flow between transgenic and conventional maize through spatial isolation.
- The study assessed outcrossing rates between yellow-kernel (transgenic) and white-kernel (conventional) maize at various distances, finding that outcrossing was highest (12.9%) at 1 meter and decreased significantly with distance.
- The results indicate that implementing spatial isolation can effectively reduce the risk of transgenic pollen contaminating local maize varieties in Mexico, supporting coexistence strategies used in other regions.
