“…DEGs encoding nucleases and vacuolar processing enzyme (VPE) were highly expressed in TZ with about 8-to 85-fold changes compared to SW-1 or SW-2 ( Figure 9; Table S6). Both nucleases and VPEs have been reported as actively involved in regular plant PCD and TE differentiation [43,44], and the plant PCD process also harbors aspartic, serine, and cysteine protease activities in the autolytic process [43,45]. Aspartic protease-encoding transcripts were detected in our DEGs.…”

“…The expression level of XBCP gene gradually reduced from SW-1 and SW-2 toward TZ, indicating the down-regulation of this DEG in TZ, where the ray parenchyma cells began to die. Two closely related cysteine proteases, XCP1 (xylem cysteine protease 1) and XCP2, are considered key autolytic enzymes produced for the PCD of TEs [43], and these two genes were highly expressed before the cell death of vessel or fiber cells [48,49]. However, similar to the expression pattern of our XBCP gene, the expressions of these two XCP genes in the ray parenchyma cells of Populus showed decreases from outer SW toward inner SW, where the ray parenchyma cells gradually die [50].…”

Taiwania (Taiwania cryptomerioides) is an important tree species in Taiwan because of the excellent properties of its wood and fascinating color qualities of its heartwood (HW), as well as the bioactive compounds therein. However, limited information is available as to the HW formation of this species. The objective of this research is to analyze the differentially expressed genes (DEGs) during the HW formation process from specific Taiwania xylem tissues, and to obtain genes that might be closely associated with this process. The results indicated that our analyses have captured DEGs representative to the HW formation process of Taiwania. DEGs related to the terpenoid biosynthesis pathway were all up-regulated in the transition zone (TZ) to support the biosynthesis and accumulation of terpenoids. Many DEGs related to lignin biosynthesis, and two DEGs related to pinoresinol reductase (PrR)/pinoresinol lariciresinol reductase (PLR), were up-regulated in TZ. These DEGs together are likely involved in providing the precursors for the subsequent lignan biosynthesis. Several transcription factor-, nuclease-, and protease-encoding DEGs were also highly expressed in TZ, and these DEGs might be involved in the regulation of secondary metabolite biosynthesis and the autolysis of the cellular components of ray parenchyma cells in TZ. These results provide further insights into the process of HW formation in Taiwania.

“…Moreover, some abiotic stress-related proteins, such as cysteine proteinase (CP, spot 4), pyridoxine biosynthesis PDX1-like protein 3 (PDX1, spot11), and alcohol dehydrogenase (ADH, spots 20) were also found to respond to high salinity and the NaCl and H 2 S treatment. An increase in the CP activity occurs just before the first senescence symptoms became visible in most plants [49]. CP is involved in PCD, and the balance between the levels of CP and phytocystatins is kept in a certain state through the antagonistic activities of abscisic acid (ABA) and gibberellins [50,51].…”

As a dominant mangrove species, Kandelia obovata is distributed in an intertidal marsh with an active H2S release. Whether H2S participates in the salt tolerance of mangrove plants is still ambiguous, although increasing evidence has demonstrated that H2S functions in plant responses to multiple abiotic stresses. In this study, NaHS was used as an H2S donor to investigate the regulatory mechanism of H2S on the salt tolerance of K. obovata seedlings by using a combined physiological and proteomic analysis. The results showed that the reduction in photosynthesis (Pn) caused by 400 mM of NaCl was recovered by the addition of NaHS (200 μM). Furthermore, the application of H2S enhanced the quantum efficiency of photosystem II (PSII) and the membrane lipid stability, implying that H2S is beneficial to the survival of K. obovata seedlings under high salinity. We further identified 37 differentially expressed proteins by proteomic approaches under salinity and NaHS treatments. Among them, the proteins that are related to photosynthesis, primary metabolism, stress response and hormone biosynthesis were primarily enriched. The physiological and proteomic results highlighted that exogenous H2S up-regulated photosynthesis and energy metabolism to help K. obovata to cope with high salinity. Specifically, H2S increased photosynthetic electron transfer, chlorophyll biosynthesis and carbon fixation in K. obovata leaves under salt stress. Furthermore, the abundances of other proteins related to the metabolic pathway, such as antioxidation (ascorbic acid peroxidase (APX), copper/zinc superoxide dismutase (CSD2), and pancreatic and duodenal homeobox 1 (PDX1)), protein synthesis (heat-shock protein (HSP), chaperonin family protein (Cpn) 20), nitrogen metabolism (glutamine synthetase 1 and 2 (GS2), GS1:1), glycolysis (phosphoglycerate kinase (PGK) and triosephosphate isomerase (TPI)), and the ascorbate–glutathione (AsA–GSH) cycle were increased by H2S under high salinity. These findings provide new insights into the roles of H2S in the adaptations of the K. obovata mangrove plant to high salinity environments.

“…Proteases are known to contribute to the execution of PCD. Although the details of the contribution of individual genes are yet to be elucidated, the expression profile of several protease genes strongly coincide with PCD in different grain tissues (Buono et al ., 2019). Such correlative evidence have been used to implicate a number of protease genes as actors during PCD of one or more cereal grain tissues.…”

5• The normal developmental sequence in a grass grain entails the death of several 6 maternal and filial tissues in a genetically regulated process termed programmed 7 cell death (PCD). The progression and molecular aspects of PCD in developing 8 grain have been reported for domesticated species like barley, rice, maize and 9 wheat. Here, we report a detailed investigation of PCD in the developing grain of 10 a wild model species, Brachypodium distachyon. 11• We detected PCD in developing Brachypodium grains using molecular and 12 histological approaches. We also identified and surveyed the expression of 13 Brachypodium orthologs of protease genes known to contribute to grain PCD. 14 • We found that Brachypodium nucellus degenerates by PCD in a centrifugal 15 pattern following anthesis, although at a slower rate compared to cultivated 16 cereals. Mesocarp PCD was not coordinated with endosperm development. 17 Brachypodium lacks an expansion of vacuolar processing enzymes known for 18 their roles in nucellar PCD. 19 • Combined with existing knowledge on grain PCD, our study suggests the 20 importance of rapid nucellar PCD for grain size and that the pattern of mesocarp 21 PCD affects grain shape. 22
