Photosynthesis is the basis of plant growth and development, and is seriously affected by low phosphorus (P) stress. However, few studies have reported for the genetic foundation of photosynthetic response to low P stress in soybean. To address this issue, 219 soybean accessions were genotyped by 292,035 high-quality single nucleotide polymorphisms (SNPs) and phenotyped under normal and low P conditions in 2015 and 2016. These datasets were used to identify quantitative trait nucleotides (QTNs) for photosynthesis-related traits using mrMLM, ISIS EM-BLASSO, pLARmEB, FASTmrMLM, FASTmrEMMA, and pKWmEB methods. As a result, 159 QTNs within 31 genomic regions were found to be associated with four photosynthesis-related traits under different P stress conditions. Among the 31 associated regions, five (q7-2, q8-1, q9, q13-1, and q20-2) were detected commonly under both normal and low P conditions, indicating the insensitivity of these candidate genes to low P stress; five were detected only under normal P condition, indicating the sensitivity of these candidate genes to low P stress; six were detected only under low P condition, indicating the tolerantness of these candidate genes to low P stress; 20 were reported in previous studies. Around the 159 QTNs, 52 candidate genes were mined. These results provide the important information for marker-assisted breeding in soybean and further reveal the basis for the application of P tolerance to photosynthetic capacity.
Luminescence
switching materials are vital to various data security-related
techniques, including data encryption–decryption. Here, we
report a family of pseudopolymorphs based on a diimine–platinum(II)
complex, Pt(Me3SiCCbpyCCSiMe3)(CCC6H4Br-3)2 (1), and systematically studied the influence of stacking modes on
luminescence switching behaviors. Upon exposure to heat or tetrahydrofuran
vapor, these pseudopolymorphs exhibit unusual stacking mode-intervened
luminescence switching (SMILS) property that non-columnar and quasi-columnar
pseudopolymorphs undergo single- and multi-step conversion processes,
respectively, to the same non-columnar products. Systematic studies
revealed that the unique SMILS behavior is caused by the existence
of stable intermediate products as well as different conversion processes
of pseudopolymorphs with distinct stacking modes. Such a new property
leads to the self-encryption function of 1, which is
very important for improving the existing data encryption–decryption
technique. On this basis, we developed a facile, reusable, equipment-free
technique with 1 as the only starting material and realized
data encryption–decryption successfully.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
