  • Water-uptake through roots, is an essential process of the water flow in plants. Its visualization is very useful for understanding sap flow dynamics at whole plant level. In this study, the tips of Arabidopsis' root hairs were excised and exposed to repeated dehydration and rehydration processes. The water-refilling through individual xylem vessels was visualized using the synchrotron X-ray micro-imaging technique. The high temporal resolution ($2\;{\mu}m$) and beam intensity of the X-ray source allowed to acquisition of consecutive X-ray images of the water-refilling process up to 10 frames/sec. Various flow patterns were observed and the ascending speed of the water-air interfaces was analyzed. The relation between the water-rising height and ascending speed was also analyzed. The present results would provide better alternative for investigating sap flows in roots.

  • Rubus hongnoensis Nakai, Korean endemic species were reexamined on the basis of morphological characters. Both sides of leaves are pubscent and particularly glandular hairs are present on main vein. All parts except petals and stems are hairy. Petioles and stem have prickles. Leaflets are 3-7. Fruits is red.

  • A new species of Copepoda, Modiolicola avdeevi (Poecilostomatoida, Sabelliphilidae) associated with the bivalve Modiolus difficilis Kuroda and Habe in the Sea of Japan, is described . Although resembling close to Modiolicola bifidus Tanaka, 1961 in the body form, the new species is distinguished from M.bifidus by the more slender antenna, stouter caudal rami and more slender leg 5.

  • To date, Periphyllus allogenes is known only in Korean peninsula, has been reported with morphological characteristics about only the aptera viviparous generation. In this study, we collected fundatrix and alate viviparous female individuals of P. allogenes samples from Gapyeong-gun, and Hongcheon-gun in Korea between 2021 and 2022. Herein, we provide new descriptions, measurements, distributions, host plants, and photographs of unknown morphs, fundatrix and alate viviparous generations of P. allogenes.
