An ancestral T2 RNase provides insights into the origin and evolution of self-incompatible S-RNase
UncategorizedAbstractWith the evolution of true floral structures, angiosperms have become the most diverse and successful plant group, a success largely attributed to the genetic diversity generated by self-incompatibility. The canonical S-RNase (class III T2 RNase)/F-boxes locus that mediates gametophytic self-incompatibility…
Tissue-specific accumulation of Na+ in leaves of two tomato species is linked to differences in symplastic transport
UncategorizedAbstractSoil salinization is a growing global threat that limits crop productivity. To cope with sodium (Na+) stress, plants have evolved tolerance mechanisms, including excluding Na+ from shoot tissues and tolerating elevated Na+ within shoots through tissue- and cellular-level mechanisms. Most current…

Call to Action: Proposed DHS Fees on Optional Practical Training (OPT)
UncategorizedThe Department of Homeland Security has proposed substantial new fees for Optional Practical Training (OPT), which allows international students on F-1 visas to work in their field of study during or after their degree programs. The proposal would require institutions to pay $70,000 for an initial OPT…
A century of soybean breeding increased photosynthetic capacity but not NPQ relaxation
UncategorizedAbstractAccelerating photoprotective regulation to improve carbon assimilation is a promising strategy to increase crop productivity. Although rapid non-photochemical quenching (NPQ) relaxation has been validated as a target through metabolic engineering, it remains unclear whether conventional breeding…
Catabolism of jasmonoyl-isoleucine modulates maize development and defense responses
UncategorizedAbstractProper spatial and temporal accumulation of the phytohormone jasmonoyl-isoleucine (JA-Ile) requires precise control of both its biosynthesis and catabolism. Two pathways for JA-Ile catabolism are the conversion of JA-Ile to 12-hydroxy-JA-Ile (12OH-JA-Ile) by JA-Ile hydroxylases, and the reversible…
Opposing modulation of QUAC1/ALMT12 by S-type channel inhibition and R-type channel activation during elevated-CO2 and ABA-induced stomatal movement
UncategorizedAbstractAtmospheric CO2 concentrations, now 50% higher than pre-industrial levels, induce plant stomatal closure. The slow (S)-type anion channels in guard cells are activated by elevated CO2/bicarbonate and promote that process. However, the response of the rapid (R)-type anion channels to CO2/bicarbonate…
The LbBLH9-LbGeBP module regulates salt gland development and salt tolerance in Limonium bicolor
UncategorizedSummaryGLABROUS1 enhancer-binding protein (GeBP) transcription factors play pivotal roles in the regulating plant development and stress responses. However, the function of GeBP family members in regulating salt gland development and salt tolerance in Limonium bicolor remains unclear. In this study,…
