semi-precious gem. The flower cluster is one of the most complete ever found in amber and appeared at a time when many of the flowering plants were
However, the Fm and photosynthetic performance parameters of rewarmed fronds (Fv/Fm and ΦPSII values) in all cases demonstrated values on average not more than 10% of values for intact control plants (Figure 5C,D and Figure S7G–L,N–Q, Table S3). These two observations suggest that, ...
Nelumbonaceae, the lotus-lily family of the order Proteales, consisting of two species of attractive aquatic plants. One of these species is the sacred lotus of the Orient (Nelumbo nucifera) and is found in tropical and subtropical Asia. The other specie
The plants (100 mg) were extracted in 1 mL freshly made solution of butanol:HCl:water (18:1:81). After boiling for 3 min, the solution was incubated at 25 °C for 24 h and then centrifuged for 40 min. The supernatant was measured for absorbance under 535 nm and then 650 nm. The...
In contrast, under Pi starvation, out5 plants formed very short primary roots and root hairs. However, OTU5 function is likely distinct from SWR1c- mediated H2A.Z deposition, as phosphate starvation response genes were not activated in the otu5 mutant (as was the case for arp6), and ...
Citrus is economically one of the most important fruit crops in the world. To date, the analysis of SBP-box genes has focused mainly on the model plants, such as Arabidopsis and rice. However, little information is known about the evolution, functions, and expression patterns of the SBP-box...
In detached leaves of eight desiccation-tolerant angiosperm species tested, drought stress did not induce desiccation tolerance suggesting that transported hormone signals may be acting in tolerance-induction in intact plants [31]. Desiccation tolerance, however, appeared to be constitutive in Myrotham...
