Transcription activator-like effector nucleases successfully generate a heritable tomato mutant.
Abstract Gibberellin (GA) regulates plant development primarily by triggering the degradation/deactivation of DELLA proteins. However, it remains unclear whether all GA responses are regulated DELLAs. Tomato (Solanum lycopersicum) has a single gene named PROCERA (PRO), and its recessive pro allele exhibits constitutive activity but retains responsiveness to external GA. In loss-of-function mutant proΔGRAS, examined developmental were considerably enhanced relative defect in seed desiccation...
The plant hormone indole-3-acetic acid (IAA or auxin) mediates the elongation growth of shoot tissues by promoting cell expansion. According to theory proposed in 1970s, auxin activates plasma membrane H+-ATPases (PM H+-ATPases) facilitate expansion both loosening wall through acidification and solute uptake. Mechanistically, however, this process is poorly understood. Recent findings Arabidopsis (Arabidopsis thaliana) have demonstrated that auxin-induced SMALL AUXIN UP RNA (SAUR) genes...
Abstract Crops with reduced nutrient and water requirements are urgently needed in global agriculture. Root growth angle plays an important role acquisition. A maize diversity panel of 481 genotypes was screened for variation root employing a high‐throughput field phenotyping platform. Genome‐wide association mapping identified several single nucleotide polymorphisms (SNPs) associated angle, including one located the expressed CBL‐interacting serine/threonine‐protein kinase 15 ( ZmCIPK15 )...
Root anatomical phenotypes present a promising yet underexploited avenue to deliver major improvements in yield and climate resilience of crops by improving water nutrient uptake. For instance, the formation root cortical aerenchyma (RCA) significantly increases soil exploration resource capture reducing metabolic costs tissue. A key bottleneck studying such has been lack robust high-throughput phenotyping platforms. We exploited approach based on laser ablation tomography, termed Anatomics...
sugary enhancer1 ( se1 ) is a naturally occurring mutant allele involved in starch metabolism maize endosperm. It recessive modifier of sugary1 su1 and commercially important modern sweet corn breeding, but its molecular identity mode action remain unknown. Here, we developed pair near-isogenic lines, W822Gse su1-ref/su1-ref se1/se1 W822GSe Se1/Se1 ), that Mendelize the phenotype an su1-ref background. kernels have lower higher water soluble polysaccharide sugars than kernels. Using...
DELLA proteins were first identified as inhibitors of gibberellin (GA) signalling but have since been shown to be involved in regulation many growth responses. GA causes responses by triggering the destruction (Willige et al., 2007). These contain a conserved domain, which is followed GRAS domain. The domain defines family proteins, including named after three members: GAI (gibberellic-acid insensitive), RGA (Repressor ga1-3), and SCR (Scarecrow). encompasses DELLA, LExLE TVHYNP motifs....
