Sorghum (Sorghum bicolor L.) a drought tolerant staple crop for half a billion people in Africa and Asia, an important source of animal feed throughout the world and a biofuel feedstock of growing importanceorghum's originated from tropical regions rendering the crop to be cold sensitive. Low temperature stresses such as chilling and frost greatly affect the agronomic performance of sorghum and limit its geographical distribution, posing a major problem in temperate environments when sorghum is planted early.

We have developed sorghum lines in the Tx430 genetic background suppressed for expression as a means of inducing epigenetic variation, and have used these materials to evaluate changes in plant growth vigor.

- Belowground microbiomes play a key role in supporting plant growth by aiding nutrient cycling and mitigating stresses related to nitrogen limitations.
- An analysis was conducted on the bacterial communities associated with different sweet sorghum genotypes under low and high nitrogen conditions to assess their sensitivity to nitrogen stress.
- Results showed distinct bacterial communities in nitrogen-stress tolerant and sensitive genotypes only under high nitrogen, and certain beneficial bacteria were more abundant in tolerant plants under low nitrogen, suggesting the importance of these microbial interactions in stress management.
