Low gibberellin (GA) activity in tomato (Solanum lycopersicum) inhibits leaf expansion and reduces stomatal conductance. This leads to lower transpiration improved water status under transient drought conditions. Tomato has three GIBBERELLIN-INSENSITIVE DWARF1 (GID1) GA receptors with overlapping activities high redundancy. We tested whether mutation a single GID1 without affecting growth productivity. CRISPR-Cas9 gid1 mutants were able maintain higher content water-deficit Moreover, while...
The pleiotropic and complex gibberellin (GA) response relies on targeted proteolysis of DELLA proteins mediated by a GA-activated GIBBERELLIN-INSENSITIVE DWARF1 (GID1) receptor. tomato (Solanum lycopersicum) genome encodes for single protein, PROCERA (PRO), three receptors, SlGID1a (GID1a), GID1b1, GID1b2, that may guide specific GA responses. In this work, clustered regularly interspaced short palindromic repeats (CRISPR) /CRISPR associated protein 9–derived gid1 mutants were generated...
Abstract The response of tree leaf gas exchange to elevated CO 2 concentrations has been investigated in numerous experiments along the past 30 years. Stomatal regulation is a major plant control over exchange, and increasing will shape biological activity forests future. Here, we collected 144 records from 57 species on stomatal conductance manipulation trees (340–980 ppm ). ‐induced downregulation was calculated as slope linear regression between [CO ]. Among species, ( ) change per 100...
Summary Gibberellins (GAs) are growth-promoting hormones that regulate organ growth, mainly via cell elongation. Contradicting reports leave an open question of whether GA is as important for root elongation it stem Here we have addressed this focusing on tomato ( Solanum lycopersicum ) primary-root We used a combination physiological, molecular and genetic approaches to tackle question. Tomato has three receptors; GID1a, GID1b1 GID1b2. The loss all receptors, strongly suppressed leaf...
Summary The promoting effect of gibberellin (GA) on primary-root elongation is well-documented in several plant species, yet its influence others, including tomato ( Solanum lycopersicum ), remains unclear. role GA has been studied using the GA-deficient mutants gib-1 and ga20-oxidase ga20ox1 ) various growth systems, Dark (D)-root D-shoot plates. application to these following germination vermiculite, promoted elongation. However, when roots grew deeper into dark environment hormone had no...
