Physiological and Anatomical Differences and Differentially Expressed Genes Reveal Yellow Leaf Coloration in Shumard Oak

Abstract: Shumard oak (Quercus shumardii Buckley) is a traditional foliage plant, but little is known about its regulatory mechanism of yellow leaf coloration. Here, the yellow leaf variety of Q. shumardii named ‘Zhongshan Hongjincai’ (identified as ‘ZH’ throughout this work) and a green leaf variety named ‘Shumard oak No. 23’ (identified as ‘SO’ throughout this work) were compared. ‘ZH’ had lower chlorophyll content and higher carotenoid content; photosynthetic characteristics and chlorophyll fluorescence parameters we… Show more

“…Mutants of ZEP and VDE have been found in various plants, including Arabidopsis npq1 , npq2 , tomato hp3 , and microalgae lhcx1 [ 56 , 57 , 58 ]. The downregulation of ZEP is often accompanied by excessive accumulation of zeaxanthin and shows reduced levels of downstream metabolites such as ABA [ 59 ].…”

“…Quantitative real-time PCR (qRT-PCR) was used to detect gene expression levels with a BIO-RAD CFX Connect Optics Module (Bio-Rad, Des Plaines, IL, U.S.A.), and their values were calculated referring to the 2 –ΔΔCt comparative threshold cycle ( C t ) method . Total RNAs were extracted using a MiniBEST Plant RNA Extraction Kit (TaKaRa, Japan).…”

“…qRT-PCR was performed using the SYBR Premix Ex Taq (Perfect Real Time) (TaKaRa, Japan) and contained 12.5 μL 2 × SYBR Premix Ex Taq, 2 μL cDNA solution, 2 μL mix solution of target gene primers, and 8.5 μL ddH 2 O in a final volume of 25 μL. The amplification was carried out under the following conditions: 95 °C for 30 s, 40 cycles at 95 °C for 5 s, 52 °C for 30 s, and 72 °C for 30 s. , All used primers were listed in Table S1 of the Supporting Information (SI).…”
