Article Synopsis
- Agriculture faces challenges from global changes, especially drought, which limits crop production, evidenced in pea (Pisum sativum) during early reproductive phases.
- The study analyzed how a water deficit affected plant growth, sugar content, and gene expression at two key stages: embryonic and seed-filling.
- Results showed significant gene regulation related to water stress in the embryonic stage, indicating a shift in sugar metabolism, highlighting the importance of transcription factors and transporters during drought response and seed development.
Grain legumes are major food crops cultivated worldwide for their seeds with high nutritional content. To answer the growing concern about food safety and protein autonomy, legume cultivation must increase in the coming years. In parallel, current agricultural practices are facing environmental challenges, including global temperature increase and more frequent and severe episodes of drought stress.

Invertases play pivotal roles in development and stress response, determining yield and quality of seed production. In this context, the repertoire of invertase gene families is critically scarce in legumes.

- In plants, roots primarily receive sucrose from aerial parts through the phloem, relying on this sugar for energy and storage.
- A portion of the carbon is released into the soil, benefiting beneficial microorganisms while also attracting parasitic microbes.
- The transport of sugars happens through cell connections (symplast) or via various membrane transporters (apoplast), which also play a role in the plant's response to environmental challenges.
The regulation of source-to-sink sucrose transport is associated with AtSUC and AtSWEET sucrose transporters' gene expression changes in plants grown hydroponically under different physiological conditions. Source-to-sink transport of sucrose is one of the major determinants of plant growth. Whole-plant carbohydrates' partitioning requires the specific activity of membrane sugar transporters.
