The fine regulation of root and stomatal architecture and physiological responses in crop plants towards drought stress is reported in the present study. The impact of water stress on relative water content (RWC), chlorophyll content, stomatal index and plant growth traits were evaluated in the two contrasting cotton varieties i.e., LRA-5166 (drought-tolerant) and NBRI-67 (drought-sensitive) during water stress. Results exhibited the significant variation in RWC, root and shoot length, root dry weight as well as an alteration in stomatal index between LRA-5166 and NBRI-67 subjected to water stress. Under water stress shoot dry weight, total dry weight and chlorophyll content in LRA-5166 were not found altered while it reduced in NBRI-67. Collectively, we demonstrated the two varieties of cotton behave differently to maintain biomass and withstand water stress. Moreover, we suggested that the physiological roles of increased root growth with reduced stomatal index distinctly maintain water homeostasis in LRA-5166 and NBRI-67 under water stress. These studies collectively demonstrated that phenotypic plasticity of root and stomata could play a significant role in regulating the biomass productivity and stress-tolerant in cotton during drought.

The strength and health of a plant are largely determined by what lies beneath the soil—its roots. But what if you could supercharge root growth, leading to healthier, more productive plants?

Scientists identify gene that triggers dramatically increased root growth

Oak Ridge National Laboratory scientists identified a gene "hotspot" in the poplar tree that triggers dramatically increased root growth. The discovery supports the development of better bioenergy crops and other plants that can thrive in difficult conditions while storing more carbon belowground. The team used a vast poplar dataset to identify regulator genes that can trigger hundreds of other gene expressions in the tree. They confirmed the molecular function of one hub gene, PtrXB38, and found that plants with the gene produced prolific and deeper roots. The gene even stimulated the growth of aerial roots on stems and leaves. The work is published in the journal New Phytologist. "With more roots, these plants absorb more nutrients, grow larger, are more tolerant to drought and can draw more carbon underground for longer-term storage," said ORNL's Wellington Muchero. The aerial roots may also make the plant more tolerant to flooding. "This naturally occurring gene has implications for biomass production, food production and climate change mitigation."

When growing roots are treated with a microtubule-depolymerizing drug, such as oryzalin, the region of elongation expands laterally, becoming bulbous and tumor like (Figure 14.17A and B). (...) The CESA units were observed to move within the plasma membrane along microtubule tracks (Figure 14.17C); they were also seen to be inserted into the plasma membrane from the Golgi apparatus at microtubule-tethered compartments.

This year I had 3 tomato seedlings have their stems eaten right through by slugs. Fortunately I was able to regrow roots on each plant by soaking in water with seaweed solution.

Top pic: the 3rd plant this happened to showing the new grown roots prior to potting up.

Bottom pic: the 2 closest plants successfully re grown and replaced into their garden bed.

Tomato plants and gardeners are amazing, resilient individuals!
