Jasmonic acid facilitates flower opening and floral organ development through the upregulated expression of SlMYB21 transcription factor in tomato

Plants coordinate the timing of flower opening with pollen and gynoecium maturation to achieve successful pollination. However, little is known about how the coordination is executed. We found that flower bud development was paused immediately before flower opening in a jasmonic acid (JA)-insensitive tomato mutant, jai1-1. Phytohormone measurement and RNA analysis in flower buds revealed that newly synthesised JA peaked at two days before flower opening and the expression of a transcription factor gene SlMYB21 delayed in jai1-1. Buds of transgenic tomato plants expressing an artificial repressor, AtMYB24-SRDX, which was expected to impede the function of SlMYB21, aborted flower opening and resembled those of jai1-1. Furthermore, the AtMYB24-SRDX plants produced abnormal pollen grains deficient in germination and pistils that did not support pollen tube elongation. We concluded that JA facilitates the expression of SlMYB21, which coordinates flower opening, pollen maturation, and gynoecium function in tomato. Jasmonic acid stimulates SlMYB21 expression, which is required for coordinated flower opening and fertility in male and female organs in tomato.ファイル公開：2019/02/15journal articl

ESR/NMR Development of double resonance system for observation of 31p nuclear spin state in low concentration Si:P and ESR measurement of dynamic nuclear polarizatio

We constructed an ESR/NMR double-resonance system for liquid-4He temperatures in order to detect a 31P-DNP-NMR signal from lightly doped (insulator) Si:P samples. We measured steady-state ESR of insulator samples of Si:P with the newly made system. DNP effect on ESR spectrum was found at 1.5 K. We also found that the magnitude of the nuclear spin polarization was changed by applying NMR pulses.research repor

Dietary carbohydrate restriction in type 2 diabetes mellitus and metabolic syndrome: time for a critical appraisal-2

Was implemented and at week 9, dieters were put on maintenance diet. Combined effect of calorie reduction and maintenance are reported at week 12. : data from Krauss, [58] were converted from reported log values in their Table 2 and per cent of baseline was calculated. : data from Sharman, [56]: A eucaloric ketogenic diet was instituted for six weeks (no weight loss phase). Points were recorded at week 3 and 6. Figure modified from Feinman & Volek [57]. Similar results were found for HDL, apoB/apoA1 and other markers of CVD [57, 58]<p><b>Copyright information:</b></p><p>Taken from "Dietary carbohydrate restriction in type 2 diabetes mellitus and metabolic syndrome: time for a critical appraisal"</p><p>http://www.nutritionandmetabolism.com/content/5/1/9</p><p>Nutrition & Metabolism 2008;5():9-9.</p><p>Published online 8 Apr 2008</p><p>PMCID:PMC2359752.</p><p></p
