“…Pi‐starvation conditions also result in a decrease in phosphorylated sugar levels in both leaves and roots, most probably due to the lower activities of fructokinase and hexokinase (Dietz and Foyer ; Rychter and Randall ). Decreased respiration rate is also one of the reasons for accumulation of soluble sugars in P‐deficient plants (Wanke et al ).…”

As an essential plant macronutrient, the low availability of phosphorus (P) in most soils imposes serious limitation on crop production. Plants have evolved complex responsive and adaptive mechanisms for acquisition, remobilization and recycling of phosphate (Pi) to maintain P homeostasis. Spatio-temporal molecular, physiological, and biochemical Pi deficiency responses developed by plants are the consequence of local and systemic sensing and signaling pathways. Pi deficiency is sensed locally by the root system where hormones serve as important signaling components in terms of developmental reprogramming, leading to changes in root system architecture. Root-to-shoot and shoot-to-root signals, delivered through the xylem and phloem, respectively, involving Pi itself, hormones, miRNAs, mRNAs, and sucrose, serve to coordinate Pi deficiency responses at the whole-plant level. A combination of chromatin remodeling, transcriptional and posttranslational events contribute to globally regulating a wide range of Pi deficiency responses. In this review, recent advances are evaluated in terms of progress toward developing a comprehensive understanding of the molecular events underlying control over P homeostasis. Application of this knowledge, in terms of developing crop plants having enhanced attributes for P use efficiency, is discussed from the perspective of agricultural sustainability in the face of diminishing global P supplies.

“…The most common cold-induced ultrastructural changes in root cells include: vacuolization, distended ER, higher number of GA cisternae, enlarged plastids deprived of starch, swollen mitochondria with reduced number of cristae, lost integrity of nuclei envelope, higher chromatin condensation and granular component disappearance from a nucleolus (Crèvecoeur et al 1983, Gašparíková et al 1996, Wanke et al 1998, Lee et al 2002.…”

Two soybean [Glycine max (L.) Merr.] cultivars: Aldana (more resistant) and Essor (less resistant to low temperature) were subjected to chilling at 5 °C for 24 h, and then the ultrastructure of the root meristem cells was investigated. The ultrastructure of control root cells of the tested cultivars differed in the number of condensed mitochondria, plastids with phytoferritin, deformed vacuoles, as well as multivesicular bodies (MB) in cytoplasm and vacuoles. Chilling induced concentric endoplasmic reticulum (ER) arrangement in both soybean cultivars, while the circular Golgi apparatus (GA) occurred only in cv. Essor and MB in the cytoplasm of cv. Aldana cells. Additionally, in cv. Aldana chilling increased the number of condensed mitochondria, MB in vacuoles and multilamellar structures (MS) in cytoplasm whereas in cv. Essor it enlarged the population of plastids with phytoferritin and the number of MB in cytoplasm. After chilling treatment the population of deformed vacuoles with phenolic compounds in the form of electron dense granules increased but the number of multilamellar structures (MS) in the vacuoles of both cultivars decreased. The ultrastructural changes induced by the chilling stress were not lethal but rather adaptive, especially in more resistant cv. Aldana.Additional key words: Glycine max, low temperature, transmission electron microscopy.

We used soil-grown pho mu tants af fected in Pi status, as well as wild-type (wt) plants grown un der Pi de fi ciency con di tions in liq uid me dium, and leaves of wt plants fed with D-mannose. Gen er ally, ApS, ApL1, Ugp and Inv genes were upregulated, al though to a var ied de gree, un der con di tions of Pi-stress. The ap plied con di tions had dif fer en tial ef fects on expres sion of other genes stud ied. For in stance, Sus1 was downregulated in pho1 (Pi-de fi cient) mu tant, but was un affected in wt plants grown in liq uid me dium un der P-de ficiency. Mannose had dis tinct con cen tra tion-de pend ent ef fects on ex pres sion of genes un der study, pos si bly re flect ing a dual role of mannose as a sink for Pi and as glu cose an a log. Feed ing Pi (at up to 200 mM) to the de tached leaves of wt plants strongly af fected the ex pres sion of ApL1, ApL2, Sus1 and Inv genes, pos si bly due to an os motic ef fect ex erted by Pi. The data sug gest that ADP-glu cose and UDP-glu cose pyrophosphorylases (en zymes in di rectly in volved in Pi re cycling) as well as invertases (su crose hy dro ly sis) are transcriptionally reg u lated by Pi-de fi ciency, which may play a role in homeostatic mech a nisms that ac cli mate the plant to the Pi-stress con di tions.
