Transcriptome and MicroRNA Analysis of <i>Juglans regia</i> in Response to Low-Temperature Stress.

ABSTRACT: Walnuts are among the globally significant woody food and oil tree species. At high latitudes, they frequently experience late-frost damage, inducing low-temperature stress, which significantly affects walnut seedlings. The aim of this study was to investigate the physiological and biochemical alterations in walnut seedlings under low-temperature (LT) stress along with its underlying molecular mechanisms. Physiological indices were determined, and the transcriptome and miRNA were sequenced by sampling leaves (0 h, 6 h, 12 h, 24 h, and 48 h) of two-month-old live seedlings of walnuts treated with a low temperature of 4 °C. The results indicated that LT stress induced an increase in electrical conductivity and malondialdehyde content while simultaneously causing a reduction in Fv/Fm. From th
