“…The interstitial wheat segments were introgressed from the common wheat cultivar ‘Pavon 76’ (also developed at CIMMYT) to eliminate the Sec-1 locus from 1RS and to incorporate the Glu-B3/Gli-B1 locus from 1BS into the 1RS chromosome to improve bread-making quality (Lukaszewski, 2000). The source of this 1RS arm was the rye cultivar ‘Petkus’, and the resulting 1RS.1BL translocation became widely distributed in wheat breeding programs around the world (Rabinovich, 1998; Schlegel and Korzun, 1997; Landjeva et al , 2006; Zhang et al , 2011).…”

“…One understudied area that can contribute to these yield increases is the role of different root architectures on wheat adaptation to different soils. Although some progress has been made in the understanding of root development and architecture in Arabidopsis (Yu and Luan, 2016; Liu et al , 2017), this knowledge is lacking in grass species (Voss-Fels et al , 2018). There have been some examples of phenotypic selection of root architecture in breeding programs (Richards et al , 2010; Wasson et al , 2012), but those methods are laborious and can be accelerated by a better understanding of the genes controlling wheat root architecture.…”

The introgression of a small segment of wheat (Triticum aestivum L.) chromosome arm 1BS in the distal region of the rye (Secale cereale L.) 1RS.1BL arm translocation in wheat (henceforth 1RSRW) was previously associated with reduced grain yield, carbon isotope discrimination, and stomatal conductance, suggesting reduced access to soil moisture. Here we show that lines with the normal 1RS arm have longer roots than lines with the 1RSRW arm in both field and hydroponic experiments. In the 1RSRW lines, differences in seminal root length were associated with a developmentally regulated arrest of the root apical meristem (RAM). Approximately 10 d after germination, the seminal roots of the 1RSRW plants showed a gradual reduction in elongation rate, and stopped growing a week later. Seventeen days after germination, the roots of the 1RSRW plants showed altered gradients of reactive oxygen species and emergence of lateral roots close to the RAM, suggesting changes in the root meristem. The 1RSRW lines also showed reduced biomass (estimated by the normalized difference vegetation index) and grain yield relative to the 1RS lines, with larger differences under reduced or excessive irrigation than under normal irrigation. These results suggest that this genetic variation could be useful to modulate root architecture.

“…Extracellular RLK domains are classified into more than 20 classes, including S-domains, leucine-rich repeats (LRR), epidermal growth factor-like (EGF), lectin-like, tumor-necrosis factor (TNF), and pathogenesis related-5 protein (PR5), etc. Although a large number of RLKs have been identified in plants, initial studies mainly focused on expression patterns and biochemical analyses, therefore, functional studies of their signal transduction pathways are still inadequate, and most RLKs are still “orphan,” i.e., the ligands and downstream targets of most RLKs in Arabidopsis and Rice ( Shiu et al, 2004 ), and a group of RLKs as cell surface receptors for root meristem growth factors are still unknown ( Yu and Luan, 2016 ), which need further investigation.…”

Leaf senescence is an evolutionarily acquired process and it is critical for plant fitness. During senescence, macromolecules and nutrients are disassembled and relocated to actively growing organs. Plant leaf senescence process can be triggered by developmental cues and environmental factors, proper regulation of this process is essential to improve crop yield. Protein kinases are enzymes that modify their substrates activities by changing the conformation, stability, and localization of those proteins, to play a crucial role in the leaf senescence process. Impressive progress has been made in understanding the role of different protein kinases in leaf senescence recently. This review focuses on the recent progresses in plant leaf senescence-related kinases. We summarize the current understanding of the function of kinases on senescence signal perception and transduction, to help us better understand how the orderly senescence degeneration process is regulated by kinases, and how the kinase functions in the intricate integration of environmental signals and leaf age information.

“…Receptor‐like kinases (RLKs) form the largest receptor family in plants (Franck et al ., 2018 ; Yu and Luan, 2016 ). Approximately 600 and 1000 RLK family members have been found in Arabidopsis thaliana and Oryza sativa , respectively (Li et al ., 2016 ).…”

Receptor-like kinases (RLKs) constitute the largest receptor family involved in the regulation of plant immunity and growth, but small-molecule inhibitors that target RLKs to improve agronomic traits remain unexplored. The RLK member FERONIA (FER) negatively regulates plant resistance to certain soil-borne diseases that are difficult to control and cause huge losses in crop yields and economy. Here, we identified 33 highly effective FER kinase inhibitors from 1494 small molecules by monitoring FER autophosphorylation in vitro. Four representative inhibitors (reversine, cenisertib, staurosporine and lavendustin A) inhibited the kinase activity of FER and its homologues in several crops by targeting the conserved ATP pocket in the kinase structure. FER contributes to the physiological impact of representative inhibitors in plants. The treatment of roots with reversine, staurosporine and lavendustin A enhanced innate immunity in plant roots and thus alleviated soil-borne diseases in tobacco, tomato and rice without growth penalties. Consistently, RNA sequencing assays showed that lavendustin A and reversine exert profound impacts on immunity-related gene expression. Our results will set a new milestone in the development of the plant RLK kinase regulation theory and provide a novel strategy for the prevention and control of plant soil-borne diseases without growth penalties.
