Enhancing drought stress tolerance and growth promotion in chiltepin pepper (Capsicum annuum var. glabriusculum) through native Bacillus spp.

The drought can cause a decrease in food production and loss of biodiversity. In northern Mexico, an arid region, the chiltepin grows as a semi-domesticated crop that has been affected in its productivity and yield. An alternative to mitigate the effect of drought and aid in its conservation could be using Plant Growth-Promoting Bacteria (PGPB).

Pepper growth promotion and biocontrol against by and formulations.

Background: genus has been used in horticultural crops as a biocontrol agent against insect pests, microbial phytopathogens, and plant growth-promoting bacteria (PGPB), representing an alternative to agrochemicals. In particular, (Bc) and (Bt) have been studied for their fungicidal and insecticidal activities. However, their use as biofertilizer formulations and biocontrol agents against phytopathogenic bacteria is limited.

First Identification of an Unusual Recombinant Potato virus Y Strain in Potato in Mexico.

Potato virus Y (PVY) has been reported in potato crops in Mexico (3), with tobacco necrotic variants found in the central State of Mexico (4). Nevertheless, many individual states are currently declared PVY free and distribution of individual strains of PVY in potato in different states of Mexico and in different solanaceous crops had not yet been studied. A limited field PVY survey was conducted on potato in the State of Chihuahua in August 2009.
