The double-recessive genic male-sterile(ms)line ms5 ms6 has been used to develop cotton(Gossypium hirsutum)hybrids for many years,but its molecular-genetic basis has remained unclear.Here,we identified the Ms5 and Ms6...
Pollen grains and plant spores have emerged as innovative biomaterials for various applications such as drug/vaccine delivery,catalyst support,and the removal of heavy metals.The natural microcapsules comprising spore...
The structurally robust biopolymer sporopollenin is the major constituent of the exine layer of pollen wall and plays a vital role in plant reproductive success.The sporopollenin precursors are synthesized through an ...

Pollen wall is the most complicated cell wall in plant. It is composed of outer exine and inner intine with the exine fiar- ther divided into sexine and nexine. The composition of in- tine layer is generally considere...
Sporopollenin exines microcapsules, derived from the naturally occurring spores of Lycopodium clavatum, have been loaded in-situ with humic acid sodium salt-Zinc (HA-Zn) complex. The chemical treatment method utilised...
