mutants, while singleathb8mutants do not show detectable changes in leaf vein patterns (Donneret al., 2009). Thus, additional regulators redundant with ATHB8 and downstream of MP are likely involved in procambial cell determination. As ATHB8 participates in cambium and/or xylem identity in both...
Xylem tissues do not have cross walls and have tubular or star-shaped structure. Present near the periphery of the vascular bundle and have larger fibers. Xylem is present in the middle of the vascular bundle and has smaller fibers. Figure 1: Xylem and Phloem Components. Credit: Kelvinsong ...
Left: a cross-section of an Arabidopsis root apical meristem. Right: a magnified image of the area of the square shown in the left panel. The central five cells in a row are xylem precursor cells functioning as a signaling center. Green represents conceivable cytokinin content, which is produ...
Leaf duration was positively correlated to the proportion of solitary vessels in an entire xylem cross section, indicating a trade-off between hydraulic efficiency and leaf duration. Across all species, earlier bud and leaf emergence in the spring was associated with a higher proportion of the ...
Through both single-cell and laser capture microdissection transcriptomic profiling, we determine the developmental lineages of ray and fusiform cells in stem-differentiating xylem across four divergent woody angiosperms. Based on cross-species analyses of single-cell clusters and overlapping trajectories, we...
If xylem is the non-living vascular tissue in plants that transports water from the roots to the rest of the plant, and constitutes the rings on a cross section of a tree, how does it grow with the re What is the main function of cuticle in plants? What is the role of turgor pressu...
Graduation date: 2005 In deciduous species, water exits stems mainly through leaf traces attached to the outer growth ring and yet we know that water ascends throughout the entire cross-section of the sapwood. There is an increasing amount of information on sap flow and sapwood hydraulic proper...
cross section of the large protease repertoire in plants. For example, coding sequences for a number of more than 550 different potential proteases, which are grouped in more than 50 different families, are found in the Arabidopsis genome [36]. The proteases identified from our analysis could ...
Figure 1.Anatomy of primary and secondary vascular tissues inArabidopsisand in comparison withPopuluswood-forming region. The same developmental phases can be identified in the cross section of(I)Populusstem and(II)6-week-oldArabidopsishypocotyl, both representing secondary vascular development, as well...
Here we identified a key regulator called CsREV, which differentially regulates xylem patterns between leaves and stems, thereby conferring drought tolerance in tea plants. When drought occurs, upregulation of CsREV activates the CsVND7a-dependent xylem vessel differentiation. However, when drought ...
