Genome-wide identification and expression analysis of Hsp70 family genes in Cassava (Manihot esculenta Crantz).

In this study, researchers identified 22 Hsp70 genes in cassava and analyzed their functions. They found that these genes are involved in various cellular processes and play a role in stress tolerance and adaptation. This information can help scientists make informed decisions for their lab regarding stress management in cassava.

A dual transcriptomic approach reveals contrasting patterns of differential gene expression during drought in arbuscular mycorrhizal fungus and carrot.

This study looked at how arbuscular mycorrhizal (AM) fungi and carrot plants respond to drought. Drought decreased photosynthesis and plant growth, and decreased root colonization. Genes related to symbiosis were downregulated in carrot but upregulated in the fungus. This shows that carrot plants reduce their investment in symbiosis during drought, while the fungus increases its efforts.
