Tobacco drought stress responses reveal new targets for

The Solanaceae are an economically important family of plants that include tobacco (Nicotiana tabacum L.), tomato, and potato. Drought is a major cause of crop losses. We have identified major changes in physiology, metabolites, mRNA levels, and promoter activities during the tobacco response to drought. We have classified these as potential components of core responses

How Drought Affects Plants East Texas Gardening

Oct 14, 2011Here is a short overview on how drought affects plants, so you can understand why this dry spell could continue to affect trees for months or years even after the drought ends. One definition for drought is the absence of rainfall or supplemental irrigation for a period of time sufficient to deplete soil moisture and injure plants.
