Title: HIT THE HEAT STRESS ON DIPLOTAXIS TENUIFOLIA
Authors: D'ATTI D, COLOZZA D, FAINO L, MENDES M, PAJORO A
Publisher Information: Società Italiana di Genetica Agraria, 2024.
Publication Year: 2024
Subject Terms: Diplotaxis tenuifolia, heat stress, PCD, translational biology, modern breeding
Description: Italy, particularly the Sele Plain area in the province of Salerno, is one of the world's largest producers of Diplotaxis tenuifolia, a perennial plant also known as “wild rocket”. D. tenuifolia suffers from climate change, rising temperature increases plant sterility and, as a result, reduction in agricultural yields. Heat stress (HS) induces programmed cell death (PCD). In the model plant Arabidopsis thaliana, a species belonging to the Brassicaceae family as D. tenuifolia, PCD is the last step of cellular development for plant cell like synergid cells present in the female gametophyte. When the pollen tube contacts synergid cell actives PCD and there is the release of two sperm cells that fuse with egg and central cells to produce the embryo and the endosperm; for this reason, PCD is essential for the fertilization process and seed production. It has been shown that high temperature anticipates plants PCD, compromises fertilization and therefore seed development. However, little is known about the mechanisms that are involved in PCD during heat stress and the conservation among different species.
